Multilin DGCS Switch Controller Chapter 2: Overview
Overview
Description of the DGCS Controllers The distribution feeders are equipped with feeder DGC Switch Controllers (pole-top, padmount) that are typically installed at the source end of the feeder. Distribution circuits called “laterals” are connected between two consecutive feeder switches. They are protected by over-current fuses and they are not automated. A typical distribution feeder layout is depicted in Figure below.
MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL

DESCRIPTION OF THE DGCS CONTROLLERS
CHAPTER 2: OVERVIEW
Figure 2-1: Typical distribution feeders layout
The switches are grouped into three main groups: •
Reclosers: These switches are capable of interrupting fault currents. They are similar to breakers.
•
Load Breaking Switches: These switches are not capable of interrupting fault currents, but can interrupt load currents. They can open only during a normal load condition, or when the circuit breaker in the substation is opened.
•
No-load switches: These switches are not capable of interrupting neither during fault, nor during normal load conditions. They can only open or close when the circuit breaker in the substation is opened.
As mentioned before, the DGC Switch Controller is intended to control load and no-load breaking switches. The switches are usually located on the trunk of the distribution feeder. The controller is equipped with 6 voltage and 3 current inputs that can be connected to voltage and current transformers respectively, or to any other voltage and current sensors with AC outputs within the specified voltage and current ranges. The controller uses two auxiliary contacts (52a and 52b) to detect open/close switch position, and produce an alarm flag in case of the contacts discrepancy. This is implemented in a hardcoded logic producing output flags that can be used to build user defined logic. The DGCS is equipped with a set of standard function elements available for the user through inputting related setting values. Additional functions that are not part of the standard DGCS element set can be easily configured and implemented using FlexLogic™ functionality. The controller is equipped with MDS radio that securely transmits data to the subscribed distribution automation devices, relays, SCADA, etc. The transmission uses DNP 3.0 protocol. The figure below depicts the section of a distribution feeder, where a DGC Switch Controller is used:

MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL
CHAPTER 2: OVERVIEW
DESCRIPTION OF THE DGCS CONTROLLERS
Figure 2-2: DGCS used as a feeder switch controller
The controller is equipped with the following AC inputs: •
6 PT inputs (Ph-Ph / Ph-N configurations)
•
3 CT inputs (Phase currents)
The main purpose of the DGC Switch Controller is to provide voltage and power measurements, voltage- and current-based computations, as well as several other digital parameters at the local point. In addition, this information can be transmitted to the remote user. MAIN FUNCTIONS OF THE DGC SWITCH CONTROLLER
The DGCS provides two modes of operation: •
Remote mode
•
Local mode
The mode can be selected only by using the faceplate pushbutton. When in Remote mode, the DGCS accepts remote commands to operate the switch. When in Local mode, remote commands are blocked and only local commands can be executed. The local commands are available only at the DGCS faceplate (pushbuttons, keypad and LED). The DGCS provides two types of the open/close command execution: •
Manual
•
Auto
In Manual, the user is directly issuing an open or a close command to the controller. In Auto, the commands are executed by programmable function elements that are running on the controller. Both (open and close) commands are interlocked with various detection functions in order to avoid the switch to be operated at certain current and voltage levels (depending on the switch type). The DGC Switch Controller is capable of measuring three phase voltages and currents from the electric distribution line. Based on the measured quantities, it can perform the following: AC Parameters Level Detections •
Power Loss

AC PARAMETERS LEVEL DETECTIONS
Each level detection function generates a flag that is logged as an event. Power Loss: The controller provides a technique of specifying minimum load current (xCT) threshold and minimum voltage (xVT) threshold. When both quantities are below the threshold (pickup) level, the DGCS will generate a flag representing power loss. Phase Instantaneous Overcurrent:: The controller provides a technique of specifying the instantaneous overcurrent condition for the switch, and generates a flag during overload conditions. The flag may be used to block the opening of the switch, if the overload level is above the switch rating. The flags are generated and reported to the master host via the radio communications. Phase Timed Overcurrent: The controller provides a technique of specifying the timed overcurrent condition for the switch. The user can select different overload curves as a part of the setup procedure for the actual application. During the overload condition the controller generates a flag. The flag may be used to block the opening of the switch, if the overload level is above the switch rating. The flags are generated and reported to the master host via the radio communications. Neutral Instantaneous Overcurrent: The controller provides a technique of specifying the maximum allowed neutral current level above which the controller generates a flag to indicate abnormal ground fault condition. Overvoltage: The controller provides a technique of setting the maximum phase voltage level, above which the controller generates a flag to indicate abnormal overvoltage condition. Phase undervoltage: The controller provides a technique of setting the minimum phase voltage level, below which the controller generates a flag to indicate loss of potential condition. Voltage unbalance and phase loss: The controller provides a technique of setting the maximum negative sequence voltage level, above which the controller generates a flag to indicate voltage unbalance condition. Another (higher) maximum negative sequence voltage level can be set above which a phase loss flag will be generated. AUTOMATIC LOGIC FUNCTIONS
Auto Sectionalizing: The Auto sectionalizing element provides a good mechanism to localize a fault by coordinating this function with the reclosing operations of the feeder breaker within a timing schedule. The logic implemented in this element provides a way to detect several reclosing actions from the main circuit breaker and accordingly open the local switch, in periods when the voltage is absent. The logic uses the information of the overcurrent condition followed by a loss of voltage, loss of current, power flow direction and voltage detection functions to execute the transition into internal states. CLP Cold load pickup: The CLP function is used to avoid fault detections under energizing or inrush conditions. The Cold Load pickup provides two different working ways: Time Block and Multiplier factor. When the CLP is programmed, the energizing process is detected by the transition from a ‘no voltage and no current’ state to a ‘voltage and current present’ condition. Time Block selected: After a CLP condition is detected, the time overcurrent functions are blocked during the period of time programmed in CLP function. Multiplier factor selected: Each Overcurrent element is provided by a setting to indicate the factor at which the pickup threshold of the function shall be increased under inrush conditions. If the current magnitude measured is higher this setting, the element will operate. COMMUNICATION CAPABILITIES

MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL
CHAPTER 2: OVERVIEW
DESCRIPTION OF THE DGCS CONTROLLERS
The DGC Switch Controller can measure/compute electrical quantities, detect the status of the grid equipment and produce various alarms and events. This information can be sent to the distribution center by means of the Distributed Network Protocol (DNP) communications. In addition, the DGCS can receive different status information and commands through the DNP. MEASUREMENTS
The measurements provided by DGCS are as follows: On the Source side
UNITS
-Ph-N and Ph-Ph Voltages. -Neutral Current -Phase Current -Positive Sequence Voltage -Negative Sequence Voltage -Zero Sequence Voltage -Positive Sequence Current -Negative Sequence Current -Zero Sequence Current -3Ph active Power -3Ph Reactive Power -3Ph Apparent Power -Power Factor -Frequency -THD Currents (up to 8th harmonic) -THD Voltage (up to 8th harmonic)
[V or kV]. (Secondary or primary) [A] [A] [V] [V] [V] [A] [A] [A] [kW] [kVAr] [kVA] [Hz] % %
On the Load side -Ph-N and Ph-Ph Voltages. -Positive Sequence Voltage -Negative Sequence Voltage -Zero Sequence Voltage -THD Voltages (up to 8th harmonic)
[V or kV]. (Secondary or primary)-[V]-[V]-[V]-%
The DGCS calculates the 3ph power based on currents from Wye connected CTs , and either voltage inputs from Wye connected PTs, or Delta connected PTs. In addition, two PTs or either only one PT can be used. The controller has to be configured for different PT connections in order to compute the 3ph power properly. The DGC Switch Controller provides DFT and RMS measurements. The internal metering process is executed at the internal frequency rate of 1 /4 of a full cycle. MONITORING AND CONTROL FUNCTIONS
The DGC Switch Controller is able to monitor the switch state based on auxiliary input 52a /52b provided by the feeder switch. Several external inputs for monitoring possible errors are also mounted on the switch: - Low charge limit switch (LCL) - Spring Charge limit (SCL) - Disconnect Closed & Latched (DCL) - Open visual disconnect contact These inputs can be used to inhibit any possible local and remote closing and opening commands to the feeder switch. The controller is able to monitor other external states as low battery conditions, high and low ambient temperature (if the order code included an RTD input card), etc. Maintenance Elements The maintenance elements provide alarms to the system based on: •
Maximum number of closing/opening executed commands per period of time
•
I2t measurements per feeder.
Data Logger
MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL
2–5
DESCRIPTION OF THE DGCS CONTROLLERS
CHAPTER 2: OVERVIEW
The DGCS provides data logger capabilities. The data logger stores the current and voltage measurements of three phases per feeder at every minute (the interval is configurable). It can also store the 3 Ph active and reactive power. A minimum of 72 hours should be stored for statistical features. There are two more buffers containing information over the largest current values reached. •
The largest value per hour is also stored in the ‘peak hourly register’. A minimum of 72 values should be stored for statistical features.
•
The largest value per 72 hour is also stored in the ‘peak 72 hour register’ buffer.
Event Recorder The DGCS can store up to 1024 consecutive events. Operate and dropout events of fault detection functions can be enabled or disabled by settings. A snapshot of the phase voltage/current and power metering can also be included and stored at each Event. Some of events and alarms include the following: •
Remote mode
•
Local mode
•
Remote/Manual Close command
•
Remote/Manual Open Command
•
switch opened/ closed / failed
•
Overload events
•
Overvoltage events
•

IN SERVICE:
The DGCS is operational and functioning properly when the “In-Service” LED shows green. The LED turns off upon detection of an internal firmware or hardware error. The product is not programmed when shipped, and the “In-Service” LED will not light upon power up. The LED will turn on green upon selecting the “Ready” setting under the S1 INSTALLATION/PRODUCT STATUS menu.
ALARM:
The “Alarm” LED turns orange upon detection of either an internal firmware error, a hardware error, or upon ALARM conditions driven by the control of the configuration elements such as “phase IOC” or “phase TOC”.
COMMS OK:
The communications LED, is a bi-color LED, meaning that it will show green when the transmit/receive channels are set and the DGCS is communicating with another smart device or SCADA. This LED will turn orange if the communication channels – communication card failure, or communication channels - are not working properly.
4 X 20 CHARACTER LCD The DGCS has an LCD with 4 lines of 20 characters, that allows visibility under varied lighting conditions. When the keypad and the display are not being used, system information is displayed after a user-defined period of inactivity. Pressing the keypad when the screen shows the default display returns the display to the last available message before the default screen activated. Any DGCS control actions, as well as element operations, are displayed automatically, overriding any target message displayed at that time. The display and the navigation keypad are conveniently located to provide the user easy access to any settings, actual values, status, monitoring tools, or statistics. NOTE:
NOTE
Pressing any of the Quick Settings pushbuttons, invokes only the settings programmed in the active Settings Group. Accessing and editing of settings from the other Settings Groups can be done using the navigation keypad pushbuttons. SWITCH CONTROLLER CONTROL PANEL The Switch Controller control panel includes the following pushbuttons: Figure 4-2: Switch Controller Control Panel
Working with the Keypad The display messages are organized into a Main Menu, pages, and sub-pages. There are four main menus labeled Actual Values, Quick Setup, Settings, and Maintenance.

Password security is an optional feature of the DGCS which can be setup using the EnerVista DGCS Setup software. The password system has been designed to facilitate a hierarchy for centralized management. This is accomplished through a Master level access password which can be used for resetting lower level access passwords and higher level privileged operations. In cases where operational security is required as well as a central administrative authority then the use of the password system is highly encouraged. The feature robustness of this system requires it to be managed exclusively through the EnerVista setup software. This section describes how to perform the initial setup. For more details on the password security feature, refer to Chapter 6 - Password Security. 1.

DGCS devices shipped from the factory are initially set with security disabled. If the password security feature is to be used, the user must first change the Master Reset Password from the initial Null setting. This can be done only over communications, not from the front panel keypad. The new Master Reset Password must be 8 to 10

characters in length, and must have minimum 2 letters and 2 numbers. The letters are case sensitive. After entering a valid Master Reset Password, enter the new Master Reset Password again to confirm, then select Change Password.
2.
Now that the Master Reset Password has been programmed, enter it again to log in to the Master Access level. The Master Level permits setup of the Remote and Local Passwords. If the Master Reset Password has been lost, record the Encrypted Key and contact the factory to have it decrypted.
3.
With Master Level access, the user may disable password security altogether, or change the Master Reset Password.
4.
The Master Access level allows programming of the Remote Settings and Remote Control passwords. These passwords are initially set to a Null value, and can only be set or changed from a remote user over RS485 communications. Remote Passwords must be 3 to 10 characters in length.

CHAPTER 4: INTERFACES
5.
Initial setup of the Local Settings and Local Control passwords requires the Master Access level. If Overwrite Local Passwords is set to YES, Local passwords can be changed remotely only (over RS485). If Overwrite Local Passwords is set to NO, Local Passwords can be changed locally only (over USB or keypad). If changing Local Passwords is permitted locally, the keypad user can only change the Local Passwords if they have been changed from the initial NULL value to a valid one. Local Passwords must be 3 to 10 characters in length.
6.
If any Remote Password has never been set, that level will not be attainable except when logged in as the Master Level. The same logic applies to the Local Passwords.
7.
When passwords have been set, the user will be prompted to enter the appropriate password depending on the interface being used (remote or local), and the nature of the change being made (settings or control). If the correct password is entered, the user is now logged into that access level over that interface only. The access level turns off after a period of 5 minutes of inactivity, if control power is cycled, or if the user enters an incorrect password.

Password security Password security features are designed into the relay to provide protection against unauthorized setting changes and control. The relay has programmable passwords for both Local and Remote access, which can be used to allow settings changes and command execution from both the front panel and the communications ports. These passwords consist of 3 to 10 alphanumeric characters. The Local and the Remote passwords are initially set after entering in a Master Reset Password (MRP). The Master Reset Password (MRP) is set to “NULL” when the relay is shipped from the factory. When the MRP is programmed to “NULL” all password security is disabled.. The remote user may choose to allow the local user to change the local passwords. Each interface (RS485, USB, and front panel keypad) is independent of one another, meaning that enabling settings access on one interface does not enable access for any of the other interfaces (i.e., the password must be explicitly entered via the interface from which access is desired). The EnerVista DGCS Setup software incorporates a facility for programming the relay’s passwords as well as enabling/disabling settings access. For example, when an attempt is made to modify a settings but access is restricted, the program will prompt the user to enter the password and send it to the relay before the settings can actually be written to the relay. If a SCADA system is used for relay programming, it is up to the programmer to incorporate appropriate security for the application. Aside from being logged out of security, which allows the user to read settings and actual values only, three levels of security access are provided: settings Level, Control Level, and Master Level. The settings and Control Levels can be attained either locally using the Local passwords (USB port and keypad), or remotely using the Remote passwords (RS485 port). The user can have either settings or Control Level active, but not both simultaneously from the same interface. The Master Level is used for setting and resetting of passwords, and includes all settings and Control Level access rights. The Master Level cannot be attained from the keypad. The Master Reset Password must be 8 to 10 characters in length, and must contain at least 2 letters and 2 numbers. The Master Level can define whether the local user is permitted to change Local Passwords without having to enter the Master Level. The Master Reset Password is encrypted, and is not viewable from the keypad. If the Master Reset Password is lost, the user should contact the factory to decrypt the Master Reset Password.

The DGCS is equipped with one serial RS485 communication port. The RS485 port has settings for baud rate and parity. It is important that these parameters agree with the settings used on the computer or other equipment that is connected to these ports. This port may be connected to a computer running the EnerVista DGCS Setup software. This software can download and upload setting files, view measured parameters, and upgrade the device firmware. A maximum of 32 -series devices can be daisy-chained and connected to a DCS, PLC, or PC using the RS485 port. Select the Settings > Communications > Serial Ports menu item in the program, or the SETTINGS > S1 PRODUCT SETUP > COMMUNICATIONS > RS485 path on the display, to configure the serial port.

BAUD RATE Range: 9600, 19200, 38400, 57600, 115200 Default: 115200 This setting specifies the baud rate (bits per second) for the RS485 port. PARITY Range: None, Odd, Even Default: None This setting specifies the parity for the RS485 port.
Modbus
The Modicon Modbus protocol is supported by the DGCS. Modbus is available via the RS485 serial link (Modbus RTU). The DGCS always acts as a slave device, meaning that it never initiates communications; it only listens and responds to requests issued by a master device. A subset of the Modbus protocol format is supported that allows extensive monitoring, programming, and control functions using read and write register commands. Refer to the DGCS Communications Guide for additional details on the Modbus protocol and the Modbus memory map. The Modbus server can simultaneously support two clients over serial RS485. The server is capable of reporting any indication or measurement and operating any output present in the device. A user-configurable input and output map is also implemented. The DGCS operates as a Modbus slave device only Select the Settings > Communications > Modbus > Protocol menu item in software, or the SETTINGS > S1 PRODUCT SETUP > COMMUNICATIONS > MODBUS path to set up the modbus protocol as shown below.
The following Modbus settings are available: MODBUS SLAVE ADDRESS Range: 1 to 254 in steps of 1 Default: 254 This setting specifies the Modbus slave address . Each device must have a unique address from 1 to 254. Address 0 is the broadcast address to which all Modbus slave devices listen. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur. Generally, each device added to the link should use the next higher address starting at 1. Please refer to the DGCS Communications Guide for details on how to set up the Modbus communications protocol.

Open/Close Setup The recloser Control feature has a programmable menu where the user can set the criteria for open and close commands to the installed load or no load break recloser. DGCS has one dedicated output relay for the “Open” command and another one for the “Close” command. Depending on ordered controller, the DGCS may have a number of other auxiliary output relays that can be programmed to close/open logic as well. The logic diagrams below show how the open and close commands are individually generated. recloser control outputs will energize when the respective close/open request is generated, unless any blocking condition exists. De-energizing of the outputs is controlled by the state of the recloser as monitored by its 52a and/or 52b contact and delayed by a settable period of time. Details are shown in the table below, “recloser Auxiliary Contacts and recloser Operation”.

In Manual mode, the DGCS controls the recloser by responding to manually performed commands from the faceplate pushbuttons OPEN and CLOSE. In Automatic mode, the decision to send a Recloser Open command will made by Control elements, if it is enabled. In both modes the DGCS controller sends either Open or Close command to the recloser using two digital outputs: RLY 1 RCR OPEN and RLY 2 RCR CLOSE. With Remote mode selected when in AUTO mode, the recloser can be also controlled by either the OPEN/CLOSE commands sent via communications, or via asserting inputs configured in the Remote Inputs menu: REMOTE OPEN CMND and REMOTE CLOSE CMND. The remote control overrides the automatic control. After the remote regulation is performed, the controller will revert back to automatic mode. Block Auto mode from Communications (COMM BLOCK AUTO) The Auto mode can be blocked remotely by asserting the command COMM BLOCK AUTO via communications. This can be done only by using the EnerVista DGCS Setup program while in Remote control. In this case the recloser can be controlled only remotely. This command is not visible on the HMI. Save Block Auto from Communications (SAVE COMM BLK AUTO) While in Remote mode, the user can select to keep the Auto mode blocked during loss of communication or loss of power to the DGCS, by setting the command SAVE COMM BLK AUTO, to “Enabled”. This will keep the Auto mode blocked after the communication or the power to the DGCS has been restored. Unblock Auto mode from Communications (COMM UNBLOCK AUTO) Both the COMM BLOCK AUTO and the SAVE COMM BLK AUTO selections will reset upon issuing COMM UNBLOCK AUTO command.

Battery backup The DGCS is capable of controlling the feeder switch in different conditions including power loss. The power loss can occur if the feeder circuit breaker opens up or there is a distribution grid blackout. During all power loss conditions, the DGCS is supplied from a backup battery. It is sized to keep the DGCS running for 8 hours. During normal running conditions, the battery is connected to the charger. Switching to different modes of operation is controlled by a standard IO-E module. This module is inserted in the second slot of the two DGCS racks, reserved for IO-E modules. The hardware described above is referred to as DGCS Battery Backup System (BBS). The battery is a Sealed Valve Regulated Lead Acid (SVRLA) battery. A slow “3 step charging cycle” is recommended for optimal charging of SVRLA batteries. Improper charging is among the most common problems of premature failure of Lead Acid batteries. The preferred three step charging procedure is common for SVRLA batteries and consists of a constant current step followed by two steps of constant voltage. In the first step, BULK

CHAPTER 6: SETTINGS
S2 SYSTEM SETUP
step, a constant current is applied to the battery until the battery voltage reaches a level of 80% State of Charge (SOC). The next step of charging is referred to as the TOP OFF or ABSORPTION step, and holds the 80% SOC voltage constant until the battery is not accepting any more charge (or until a pre-set timer in the controller has expired). At this point, the voltage is dropped to a new level and held constant in what is called the FLOAT step, so that the battery remains fully charged. This profile is optimal for most lead acid batteries. For 24 V battery systems, the voltage (at 25°C) should be within the range of 28.4 to 30 V. The battery backup is not like a traditional standard battery and charger. The system implemented is in fact simpler as it splits the charger into two parts: a power supply and a charger controller. The main reason a traditional method cannot be implemented is because no off the shelf charger exists that meets the wide temperature range of –40° to 60° and can withstand GE type test requirements. It is also important to capture the minimum and maximum voltages that the load can withstand. The minimum turn ON voltage for the load Switch Controller is 20VDC. The battery should therefore supply power down to 20VDC and then cut the load off to prevent deep discharge. A Battery Management System (BMS) board is implemented to the BBS to optimize battery life and provide useful feedback to the DGC. The BMS board will output the following to the DGC: 1.
Battery Low warning (19.6 V)
2. Battery fuse blown. Main function The connections of the BBS components are shown in the following BBS wiring diagram. Under normal running conditions, the main power supply feeds the DGCS and the battery charger. When a power loss condition occurs, the battery supplies power to the DGCS. Occasionally, the system checks the battery condition. MODES OF OPERATION Run In normal running condition, the power is fed from the unit labeled ‘POWER SUPPLY’, contact output 1 is closed, and contact output 2 is open. So, the battery is connected to the charger (unit labeled ‘CHARGER’) and its capacity is constantly being maintained at optimum level. In addition, the DGCS CPU power input is constantly energized. Once the unit is completely shut-off it cannot be powered by Battery only. An AC source must be applied to turn the unit on. Backup The BBS switches to this mode, when the power is down. In Backup mode, terminals labeled ‘BATTERY’ connect to terminals ‘DC LOAD’ inside the charger (unit labeled ‘ROGUE’) allowing the battery to feed the DGCS. Contact output 1 is closed, and contact output 2 is open. Test Battery test In test mode, the battery is disconnected from the charger and connected to an 8 ohm resistor for a certain time period that can be programmed in the BBS menu. During the test, Contact output 1 is open and Contact output 2 is closed. The duration of the test can be programmed. If the voltage stays above the contact input threshold (19.4 V) during the test, the battery will be considered healthy. Otherwise, the test aborts, and an alarm flag is set. The sequence is initiated periodically. The time between two tests can be set. In addition, pushing the button labeled ‘BATTERY TEST’ on the front panel, initiates the testing sequence.

Fuse test The Battery fuse test is performed simultaneously with the battery test by checking the state of Contact inputs 1 and 2. If both are detected high, the fuse is considered healthy. If Contact input 2 is high but Contact input 1 is low, the fuse blown alarm will be set. Battery alarm LED This is a red LED located on the front panel. The LED light is off during normal operation.

10 Amp Capacity: The charger can facilitate a total of 10 amps to charge the battery and power the load.
•
Temperature Compensation: The charger has an internal temperature sensor and varies charging voltages accordingly.
•
3-stage Operation: The charger uses a 3 stage system to optimize lead acid battery charging. (Refer to graph for typical charging pattern).
The controller terminals are listed below:

A microcontroller reads the battery and power input voltages, along with a set of internal timers and other logic, and determines what the state of the switches (FETs) should be. The two switches are controlled and activated independently, such that either one, both, or neither switch can be activated at any given time. Figure 6-7: BMS Charge Graph
The graph above shows an ideal charging cycle typically found after a lead acid battery has discharged overnight. The red line (upper) indicates the battery terminal voltage and the green line (lower) indicates the charging current supplied to the battery.

CHAPTER 6: SETTINGS
When the charger is first connected, or when the battery voltage drops below approximately 2.15V per cell, the charger enters bulk (fast) mode, where it attempts to bring the voltage to approximately 2.45V per cell. At this point, top-off mode is entered. When the charger senses that the battery is no longer taking a charge, float mode is entered where the voltage is lowered and maintained at approximately 2.3V per cell. The current for the load will come from the solar/power input when available, and the battery in that case will provide power filtering and smoothing to the load, while at the same time maintaining a float/trickle charge from the power source. The battery effectively acts as a large capacitor when connected in this manner
Battery safety information
To prevent fire or chemical burns: •
Do not attempt to recharge batteries after removal from the unit.
•
Do not disassemble, crush, or puncture the batteries.
•
Do not short the external contacts of the batteries.
•
Do not immerse the batteries in water.
•
Do not expose to temperatures higher than 80°C (176°F).
•
The batteries are recyclable. They contain lead and pose a hazard to the environment and human health if not disposed of properly. Return the battery to a factory authorized service center or refer to local codes for proper disposal requirements.
•
Do not open or mutilate batteries. They contain an electrolyte which is toxic and harmful to the skin and eyes.
•
Replace batteries with the same number and type of batteries as originally installed.
To prevent personal injury from hazardous energy: •
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Do not place tools or metal parts on top of batteries.

Phase TOC The settings of this function are applied to each of the three phases to produce pickup and alarm condition per phase. The TOC pickup flag is asserted, when the current on any phase is above the PKP value. The TOC alarm flag is asserted if the element stays picked up for the time defined by the selected inverse curve and the magnitude of the current. The element drops from pickup without operation, if the measured current drops below 97-

DESCRIPTION
MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL
CHAPTER 6: SETTINGS
S3 CONFIGURATION
The relay has a total of two phase, two neutral, and two ground/sensitive ground time overcurrent elements. The programming of the time-current characteristics of these elements is identical in all cases and will only be covered in this section. The required curve is established by programming a Pickup Current, Curve Shape, Curve Multiplier, and Reset Time. The Curve Shape can be either a standard shape or a user-defined shape programmed with the FlexCurve™ feature. Accurate coordination may require changing the time overcurrent characteristics of particular elements under different conditions. For picking up a cold load, a different timecurrent characteristic can be produced by increasing the pickup current value. The following setpoints are used to program the time-current characteristics. •
PICKUP: The pickup current is the threshold current at which the time overcurrent element starts timing. There is no intentional ‘dead band’ when the current is above the pickup level. However, accuracy is only guaranteed above a 1.5 per unit pickup level. The dropout threshold is 98% of the pickup threshold. Enter the pickup current corresponding to 1 per unit on the time overcurrent curves as a multiple of the source CT. For example, if 100: 5 CTs are used and a pickup of 90 amps is required for the time overcurrent element, enter “0.9 x CT”.
•
CURVE: Select the desired curve shape. If none of the standard curve shapes is appropriate, a custom FlexCurve™ can be created by entering the trip times at 80 different current values; see S2 SYSTEM SETUP > FLEXCURVE A. Curve formulas are given for use with computer based coordination programs. Calculated trip time values are only valid for I / Ipu > 1. Select the appropriate curve shape and multiplier, thus matching the appropriate curve with the protection requirements. The available curves are shown in the table below.

•
MULTIPLIER: A multiplier setpoint allows shifting of the selected base curve in the vertical time direction. Unlike the electromechanical time dial equivalent, trip times are directly proportional to the value of the time multiplier setpoint. For example, all trip times for a multiplier of 10 are 10 times the multiplier 1 or base curve values. When Timed Over-Current is programmed with Definite time, the operating time is obtained after multiplication of the selected Multiplier (TDM) by a 0.1 s base line. For example, selection of TDM = 5 would lead to a 0.5 s operating time.
•
RESET: Time overcurrent tripping time calculations are made with an internal ‘energy capacity’ memory variable. When this variable indicates that the energy capacity has reached 100%, a time overcurrent trip is generated. If less than 100% is accumulated in this variable and the current falls below the dropout threshold of 97 to 99% of the pickup value, the variable must be reduced. Two methods of this resetting operation are available, Instantaneous and Linear. The Instantaneous selection is intended for applications with other relays, such as most static units, which set the energy capacity directly to zero when the current falls below the reset threshold. The Linear selection can be used where the relay must coordinate with electromechanical units. With this setpoint, the energy capacity variable is decremented according to the following equation.

USER Curves The relay provides a selection of user definable curve shapes used by the time overcurrent protection. The User curve is programmed by selecting the proper parameters in the formula:
A, P, Q, B, K - selectable curve parameters within the ranges from the table: D is the Time Dial Multiplier. User Curve can be used on multiple elements only if the time dial multiplier is the same for each element. V = I/IPICKUP (TOC setting) is the ratio between the measured current and the pickup setting. The maximum trip time for the User Curve is limited to 65.535 seconds. The User Curve can be used for one protection situation only.

Flexcurves Prospective FlexCurves™ can be configured from a selection of standard curves to provide the best approximate fit, then specific data points can be edited afterwards. Click the Initialize button to populate the pickup values with the points from the curve specified by the "Select Curve" setting and the "Multiply" value. These values can then be edited to create a custom curve. Click on the Clear FlexCurve Data button to reset all pickup values to zero. Curve data can be imported from CSV (comma-separated values) files by clicking on the Open button. Likewise, curve data can be saved in CSV format by clicking the Save button. CSV is a delimited data format with fields separated by the comma character and records separated by new lines. Refer to IETF RFC 4180 for additional details. The curve shapes for the two FlexCurves are derived from the following equations.
In the above equations, Toperate represents the operate time in seconds, TDM represents the multiplier setting, I represents the input current, Ipickup represents the value of the pickup current setting, Tflex represents the FlexCurve™ time in seconds.

For example if an ANSI Extremely Inverse curve is selected with TDM = 2, and the fault current was 5 times bigger than the PKP level, the operation of the element will not occur before a time elapse of 495 ms from pickup. Initialization Used after specifying a curve to use as a base for a custom FlexCurve™ (see Select Curve and Multiply above). When the Initialize FlexCurve button is clicked, the pickup settings will be populated with values specified by the curve selected in this setting.

1.03 × Pickup, ..., 20.00 × Pickup Range: 0 to 65535 ms in steps of 1 Default: 0 ms These settings specify the time to operate at the following pickup levels 1.03 to 20.00. This data is converted into a continuous curve by linear interpolation between data points. To enter a custom FlexCurve™, enter the operate time for each selected pickup point. NOTE:
NOTE
Each FlexCurve can be configured to provide inverse time characteristic to more than one Time Overcurrent Element. However, for computation of the curve operating times, one must take into account the setting of the Time Delay Multiplier from the FlexCurve menu, and the Time Delay Multiplier setting from TOC menu. The true TDM applied to the TOC element when FlexCurve is selected is the result from the multiplication of both TDM settings. For example, for FlexCurve Multiplier = 5, and Phase TOC Multiplier = 2, the total Time Dial Multiplier will be equal to 10. To avoid confusion, it is suggested to keep the multiplier from the TOC menu equal to 1, and change only the multiplier from the selected FlexCurve. This way, one can see from the FlexCurve setup, the curve operating times as related to the multiples of pickup.
Neutral overcurrent The relay has one Neutral Instantaneous Overcurrent detection function. The settings of this function are applied to the calculated neutral current as a pickup flag. The Neutral IOC pickup flag is asserted when the neutral current is above the PKP value. The Neutral IOC operate flag is asserted if the element stays picked up for the time defined by the Neutral IOC Delay setting. If the pickup time delay is set to 0.00 seconds, the pickup and operate flags will be asserted at the same time. The element drops from pickup without operation if the neutral current drops below 97 to 98% of the pickup value.

The undervoltage elements can be programmed to have an inverse time delay characteristic. The undervoltage delay setpoint defines a family of curves as shown below. The operating time is given by:
T=

Eq. 1
Where: T = Operating Time D = Undervoltage Delay setpoint V = Voltage as a fraction of the nominal VT Secondary Voltage Vpu = Pickup Level At 0% of pickup, the operating time equals the Undervoltage Delay setpoint.

Power loss The Power Loss detection function is used to detect a power loss condition in each phase of the power distribution line. After opening the upstream breaker, the DGC has to confirm that the voltage and current levels of the line are below a minimum threshold.When the switch type is selected as ’no-load,’ the opening or closing commands of the switch are interlocked with this function. Any OPEN or CLOSE command will be blocked unless the currents and voltages of each phase fall below minimum set values. This function is also used by the auto-sectionalizing function to detect the power loss condition after a previous IOC fault detection. When the switch is closed, the power loss detection of the source side is used to control the opening commands execution. However, for DGC devices provided with voltage on both sides of the line, the power loss condition has to be established in both sides before closing a no-load switch into the power line.
PATH: SETTINGS > S3 CONFIGURATION > SETPOINT GROUP 1/2/3 > POWER LOSS MIN PH CURR PICKUP Range: 0.01 to 0.40xCT in steps of 0.01xCT Default: 0.03xCT This setting is used to detect the circuit breaker open condition.

CHAPTER 6: SETTINGS
Auto sectionalizing The Auto Sectionalizing function of the DGCS is designed to control a switch separating the sections of a feeder. Normally there are several switches within one feeder, each controlled by a separate DGCS. The feeder is protected by a circuit breaker installed on the source side. When there is a fault on the feeder, Auto Sectionalizing functions in all feeder DGCS units coordinate the actions of the breaker using feeder switches. At the end of the switching sequence, the switch at the entry point of the faulty section remains open, allowing the upstream sections to resume normal operation. As indicated above, the distribution feeders are equipped with feeder switches (pole-top, pad-mount) that can segment the feeder into electrically isolated sections. Distribution circuits called “laterals” (labeled as ‘Loads’) are connected between two consecutive switches. These are protected by over-current fuses and are not automated. An example of the circuit is depicted in the figure below. Figure 6-18: Typical Distribution Circuit
For the topology shown above, the assumption is that there is a fault (F2) on Feeder 1. Circuit breaker 1 will start with the trip-reclose operating profile shown below.

MULTILIN DGCS SWITCH CONTROLLER – INSTRUCTION MANUAL
CHAPTER 6: SETTINGS
S3 CONFIGURATION
Figure 6-19: Circuit Breaker Operating Profile - F2 fault condition
The circuit breaker operating steps on the profile are numbered from 1 to 12. The height of the profile step is scaled to the current and the length of the profile step is scaled to the duration of the state. The duration of steps and the number of re-closing attempts can be set on the circuit breaker controller. Usually the entire CB fault operating profile completes within 60 seconds. The number of re-closing attempts must be set to the number of feeder switches, incremented by 1. Usually, the maximum number of re-closing attempts is 4, which limits the number of sectionalizing switches to 3. In this example, there are 3 reclosing attempts (events 3, 7 and 11). Each DGCS is equipped with a CT set that is installed at the source side of the corresponding switch. Using the current readout, DGCs will detect the fault current if the fault occurred downstream of the switch. Both DGCs are in counting mode. They are counting events ‘Overcurrent followed by power supply loss’. For the last switch on the feeder (furthermost from the circuit breaker) the count limit must be set to 2 and it should increment by 1 for each switch positioned closer to the circuit breaker. In this case the DGCS_11 count limit is 3 and the DGCS_12 count limit is 2. When a DGCS unit count reaches its limit, the switch will open. Two cases will be considered: F1. The fault occurred between the Tie breaker / switch and DGCS_12. After the Auto Sectionalizing sequence is complete, the DGCS_12 will open during CB event 6. After CB step 7 is complete, the nominal current will flow through the feeder and the faulty feeder segment will be sectionalized. F2. The fault occurred between the DGCS_11 and DGCS_12. After the Auto Sectionalizing sequence is complete, the DGCS_11 will open during CB event 10. After CB step 11 is complete, the nominal current will flow through the feeder and the faulty feeder segment will be sectionalized. NOTE:
NOTE
Each DGCS is set to detect a reverse power condition. If such a condition has been detected, the Auto Sectionalizing sequence will operate, but the “Open Switch” command will not be executed.

The limit for the third last switch should be set to 4. AUTO SECT MODE Range: Timing mode, Counting mode Default: Counting mode This setting selects the mode of Auto Sectionalizing. In Timing mode, ‘Auto Sect Delay’ time should be set to the lowest value for the last switch on the feeder (furthermost from the circuit breaker). For the second last switch, the time should be longer, continuing in the same way to the first switch on the feeder. AUTO SECT DELAY Range: 0.1 to 60.0 s in steps of 0.1s Default: 0.2 s This setting selects the time delay between issuing and executing the Auto Sectionalizing command. REVERSE PWR DETECT Range: Enabled, Disabled Default: Disabled This setting selects the detection of the reverse power. When enabled, a reverse power condition triggers the message “REVERSE POWER.” REVERSE PWR PKP Range: 0 to -50000 kW in steps of 1kW Default: -50 kW This setting selects the pickup level for the reverse power detection. It is recommended to avoid setting zero for the pickup level since in that case the ‘no load’ condition will be interpreted as a ‘reverse power’ condition. REVERSE PWR DELAY Range: 0.0 to 60.0 s in steps of 0.1 s Default: 0.5 s This setting delays the reverse power detection. Reverse power has to be lower than the pickup value for more than the time in this setting, before the REVERSE POWER message is asserted. AUTO SECT TIMEOUT Range: 6 to 600 in steps of 1s Default: 60 s The Auto Sectionalizing sequence must be complete before this time elapses. If the time expires before the completion of the sequence, the sequence will reset. This time should be equal to the duration of the breaker switching sequence.

The DGCS provides counters for counting the switch OPEN and CLOSE actions. Every new OPEN action increments the content of the Flexlogic variable SWITCH OPEN COUNT. Equally, every new CLOSE action increments the content of the Flexlogic variable SWITCH CLOSE COUNT. Both variables are located in MAINTENANCE / M3 COUNTERS. The user can select the limit for each action separately. When a limit has been reached, a corresponding message is produced.

S3 CONFIGURATION
CHAPTER 6: SETTINGS
The DGCS is provided with an Arcing Current Counter that calculates the energy of the arc created for every switch open action. The calculation is performed for each phase and it is based on the instantaneous value of the KI2t being integrated for the duration of the switch open action. Furthermore, the controller adds up the arc energy of every new switch open action, creating an accumulated count of this quantity for a long period of time. The accumulated arcing energy of phase A is saved in the Flexlogic variable KI2t SW COUNT PH A, as is the accumulated arcing energy of phases B and C. The controller provides for setting the limit for arcing energy and if any of the phases’ arcing energy value exceeds this limit, the alarm message is triggered. Usually, the switch manufacturer provides the maximum KI2t value and when this value is reached, the switch has to be repaired. This makes the Arcing Current function a very useful maintenance tool. The logic diagrams for the Switch Action Counter and the Arcing Current Counter are shown below.
PATH: SETTINGS > S3 CONFIGURATION > WEARING MONITOR ACT CNTR FUNCT Default: Disabled Range: Enabled, Disabled This setting enables the functionality of the Switch Action Counter. It has two separate parts: one for counting open actions, and another for counting close actions of the switch. When enabled, every open or close action of the switch results in incrementing of the open or close count respectively. OPEN CNTER LIMIT Default: 9999 Range: 1 to 9999 Steps 1 This is the maximum number of openings allowed for the controlled switch. When this value is exceeded, the message OP CNT LIM REACHED appears to signal this issue. Once the message is activated, it can be removed by resetting the open counter. The path of the reset command is: MAINTENANCE / M3 STATISTICS/ RESET COUNTERS / RESET OPEN COUNT. When the limit of 9999 is reached the Open Counter starts from zero. CLOSE CNTER LIMIT Default: 9999 Range: 1 to 9999 Steps 1 This is the maximum number of closings allowed for the controlled switch. When this value is exceeded, the message CL CNT LIM REACHED appears to signal this issue. Once the message is activated, it can be removed by resetting the open counter. The path to the reset command is: MAINTENANCE / M3 STATISTICS / RESET COUNTERS / RESET CLOSE COUNT. When the limit of 9999 is reached the Close Counter starts from zero.

Change setpoint group
The DGCS has three identical settings groups - Groups 1, 2, and 3 - for all DGCS monitoring elements. Switching between these three groups is available either automatically by assigning an input (contact, virtual, remote, flexlogic element), or manually through communications. Group 1 is the default setting group. The device can automatically switch from Group 1 DGCS elements to the other group elements, and vice versa, by setting up the switching conditions under “Change Setpoint Group”. Under some application conditions, it may be

undesirable to change settings groups. In such cases, the user can set a condition under “BLK GROUP CHANGE”, where if asserted, the active settings group will stay active, even if the input configured to switch to the other settings group is asserted. For example if the active group was group 1 at any given time, and the input configured under “BLK GROUP CHANGE” is asserted, the relay will maintain settings group 1, even if the input “SET GROUP 2 (3) ACTIVE” is asserted. Visa versa, if the “BLK GROUP CHANGE” input is asserted, the relay will not switch from group 2/3 to group 1, even if the input under “SET GROUP 2 (3) ACTIVE” is de-asserted. The device will default to settings group 1, if both the input “SET GROUP 2 (3) ACTIVE” and the blocking input “BLK GROUP CHANGE” are de-asserted. Table group 3 of settings has a higher priority than the rest of settings groups. That means, if both “SET GROUP 2 ACTIVE” and “SET GROUP 3 ACTIVE” signals are maintained asserted at the same time, the DGCS will change to the table 3 of settings. The logic functionality takes into account this feature.
PATH: SETTINGS > S4 CONTROLS > CHANGE SETPOINT GROUP SET GROUP 2 ACTIVE Range: Off, Contact Input 1 to 12 (Order Code dependent), Virtual Input 1 to 32, Virtual Output 1 to 32 Default: Off This setting selects an input, used to change to Settings Group 2, when asserted. If no group change supervision is selected, the Settings Group 2 will stay active as long as the “SET GROUP 2 ACTIVE” input is asserted, and will revert to group 1 when this input is deasserted. SET GROUP 3 ACTIVE Range: Off, Contact Input 1 to 12 (Order Code dependent), Virtual Input 1 to 32, Virtual Output 1 to 32 Default: Off This setting selects an input, used to change to Settings Group 3, when asserted.

Cold load pickup The DGCS can be programmed to block the instantaneous over-current elements, and raise the pickup level of the time over-current elements, when a cold load condition is detected. The cold load condition is detected during closing of the breaker on a feeder that has been de-energized for a long time. The feeder inrush current and the motor accelerating current during breaker closing may be above some over-current protection settings. The diagram shows the slow decaying of the cold load current starting at about 500% of the nominal current at the time of breaker closing, decaying down to 300% after 1 second, 200% after 2 seconds, and 150% after 3 seconds.

The relay detects Cold Load condition (Cold Load Pickup armed), if the currents on all three phases drop below 3% of the CT nominal rating for the period of time greater, than the Outage Time Before Cold Load setting. The Cold Load condition can be immediately initiated (Outage Time Before Cold Load timer bypassed), by asserting a contact input selected for External CLP Initiate. The second timer Cold Load Pickup Block is used to specify the time of blocking the instantaneous over-current elements, and the time of raised pickup levels of the time overcurrent elements, after breaker closing. The timer starts when at least one of the three phase currents is above 10% of CT nominal. Upon timer expiration, the settings return to normal. The following path is available using the keypad. For instructions on how to use the keypad, please refer to Chapter 3 - Working with the Keypad.

CHAPTER 6: SETTINGS
FlexLogic™ The DGCS FlexLogic™ system, defines operators, and lists of operands. In essence, all the necessary information for custom built logic. The FlexLogic tool is accessible from the EnerVista DGCS Setup program under the SETTINGS > FLEXLOGIC menu All DGCS digital signal states are represented by FlexLogic™ operands. Each operand is in one of two states: on (asserted, logic 1, or set), or off (de-asserted, logic 0, or reset). There is a FlexLogic™ operand for each contact input, contact output, communications command, control panel command, element trip, and element alarm, as well as many others. A list of FlexLogic™ operands and operators are sequentially processed once every 4.17 ms or 5 ms, depending on the power system frequency (60 Hz or 50 Hz). When list processing encounters an operand, the value of that operand is placed in a first in - first out stack. When list processing encounters a calculation operator, the number of values required for the calculation are removed from the stack, and the result of the operation is placed back on the stack. The operators are logic gates (for example, AND, OR, NOT), timers, latches, one-shots, and assignments. Assignment operators assign the value calculated by the preceding operators to a special class of operands called virtual outputs. Like any other operand, a virtual output can be used as an input to any operator – feedback to achieve seal-in is allowed. When list processing encounters an end operator, processing is stopped until the next processing cycle, at which time it restarts at the top of the list. Each contact output has a setting to specify the operand that drives the output. Any operand may be selected – selection of a virtual output is the means by which FlexLogic™ directly controls external equipment such as the motor contactors. The operators used in FlexLogic™ conform to the following rules: •
512 lines for bulding logic are available in the FlexLogic tool. All lines are executed every 1 / 4 power system cycle (4.17 ms. or 5 ms).
•
A virtual output may only be assigned once within the FlexLogic environment. An unassigned virtual output will have a value of off.
•
A maximum of thirty (32) general purpose timers (timers 1 through 32) are available for configuration. Each timer may only be used once within the FlexLogic environment.
•
A maximum of thirty (30) one-shots is allowed.
•
A maximum of 16 latches is supported.
The operators available in FlexLogic™ are shown below:

Virtual inputs There are 32 Virtual Inputs that can be individually programmed to respond to Input commands entered via the relay keypad, or by using communication protocols. Virtual Input programming begins with enabling the Virtual Input function and selecting the Virtual Input Type - Self-Reset or Latched - under SETTINGS > S5 INPUTS/OUTPUTS. Next, under SETTINGS > S4 CONTROLS > VIRTUAL INPUTS, the user assigns either an On or an Off command to the Virtual Input enabled earlier. Referring to the Virtual Inputs logic diagram below, a Virtual Input type can be selected to be either Self-Reset, or Latched. When Self-Reset is selected, and the command On is executed, the virtual input is evaluated as a pulse at rate of one protection pass. When the Latched type is selected, the On state of the Virtual Input will be latched.

Multilin DGCS Switch Controller Chapter 8: Commands
Commands
The DGCS OPEN/CLOSE commands can be used in three different ways: •
OPEN and CLOSE commands from the DGC faceplate pushbuttons or the DGC menu. This method of control is active in Local / Manual mode, providing that the DGCS control is not set to OFF and no other blocks or switching inhibits are applied.
•
Remote OPEN and CLOSE control upon energizing of assigned inputs under SETTINGS/ CONTROLS/REMOTE CONTROL. This method of control will be active, in Remote / Manual and Remote / Auto mode, providing the DGC–S control is not set to OFF and no other blocks or switching inhibits are applied.
•
OPEN and CLOSE commands over DNP addresses using radio and the EnerVista DGCS Setup menu. This method of control will be active in Remote / Auto mode, providing the DGCS control is not set to OFF and no other blocks or switching inhibits are applied.
The DGCS RESET command is available on the faceplate keypad button, shown below, and in the Commands menu. Figure 8-1: DGC faceplate OPEN/CLOSE commands

CHAPTER 8: COMMANDS
The Switch OPEN and CLOSE commands received via the selected inputs, are executed if the DGCS control is enabled and the selected control mode is Remote (the Remote LED is lit). The remote OPEN and CLOSE commands are blocked if the “Local” control mode is selected (the “Local” LED is lit) or the corresponding BLOCK command is active. The Remote Reset command can be executed by asserting the selected input when the controller is in Remote mode. PATH: S4 SETPOINTS > CONTROLS > REMOTE CONTROL REMOTE OPEN Range: Off, Contact Input, Virtual Input, Virtual Output Default: Off This setting defines the Input to trigger the OPEN command to the switch. This Input can be selected from the list of Inputs including Contact Inputs, Virtual Inputs, Protection or Control Operand, as well as Input Flags received from SCADA, or IEDs. REMOTE CLOSE Range: Off, Contact Input, Virtual Input, Virtual Output Default: Disabled This setting defines the Input to trigger the CLOSE command to the switch. This Input can be selected from the list of Inputs including Contact Inputs, Virtual Inputs, Protection or Control Operand, as well as Input Flags received from SCADA, or IEDs. REMOTE RESET Range: No, Off, Contact Input, Virtual Input, Virtual Output Default: Off This setting is used to reset the LEDs, alarms, and target messages generated during some abnormal Switch condition. The setting provides for the selection of an Input from a list of Inputs, that performs the RESET action upon activation. OPEN and CLOSE commands over DNP addressing, using radio The OPEN or CLOSE command can be initiated from a SCADA or an IED using radio communication. The controlling device maps an OPEN or CLOSE command to its binary outputs and transmits them via radio communication to the controller. Upon receipt the DGCS controller executes the appropriate action. The DGCS controller executes the received commands, if the controller is not in OFF mode and the selected control mode is set to “Remote” (the Remote LED is lit). The remote OPEN and CLOSE commands via radio, are blocked if the “Local” control mode is selected (the “Local” LED is lit).
