System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Correct use The safety system MGB-L1B-... / MGB-L2B-... is an electromagnetic interlock device with guard locking. The system comprises at least one locking module MGB-L1B-... / MGB-L2B-... and one handle module MGB-H... The locking module MGB-L1B-PN.-... / MGB-L2B-PN.-... is operated as an IO device in the PROFINET (PROFIsafe). In combination with a safety guard and the machine control, the MGB system prevents the safety guard from being opened while a dangerous machine movement is being performed. For the control system, this means that

 starting commands which cause hazardous situations must become active

only when the safety guard is in protective position and the guard locking is in locked position. The locked position of the guard locking must be released only when the hazardous situation is no longer present.

Before safety components are used, a risk assessment must be performed on the machine, e. g., in accordance with

 EN ISO 13489-1, Safety of machinery. Safety related parts of control systems. General principles for design

 EN ISO 14121, Safety of machinery. Risk assessment. Principles. Correct use includes compliance with the relevant requirements for installation and operation, in particular

 EN ISO 13489-1, Safety of machinery. Safety related parts of control systems. General principles for design

 EN 1088, Safety of machinery. Interlocking devices associated with guards. Principles for design and selection

 EN 60204-1, Safety of machinery. Electrical equipment of machines. General requirements.

The safety system MGB can only be combined with the intended modules in the MGB system family. On the modification of system components, EUCHNER provides no warranty for safe function. The customer is responsible for the safe overall function, especially for the safe integration into the PROFIsafe environment. Important!

 The user is responsible for the integration of the device into a safe overall system. For this purpose, the overall system must be validated, e.g. in accordance with EN ISO 13849-2.  Correct use requires observing the permissible operating parameters (see Technical data).  If a product data sheet is included with the product, the information on the data sheet applies in case of discrepancies with the operating instructions.  In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed for the MTTFd according to the limit value in EN ISO 13849-1:2008, Section 4.5.2. This corresponds to a minimum value for the PFHd of 2.47x10-8/h.

Exclusion of liability and warranty In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void.

General safety instructions Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel. Check the safe function of the safety guard particularly

 after any setup work  after the replacement of an MGB component  after an extended period without use  after every fault Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the maintenance schedule. Warning! Loss of safety function in the event of incorrect connection or incorrect use.  Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. On this topic pay attention in particular to the measures for reducing the possibility of bypassing from EN 1088:1995+A2:2008, Section 5.7.  The switching operation is only allowed to be triggered by the intended handle module MGB-H... that is positively fastened to the safety guard. The device is only allowed to be installed and placed in operation by authorized personnel  who are familiar with the correct handling of safety components  who are familiar with the applicable EMC regulations  who are familiar with the applicable regulations on health and safety and accident prevention  who have read and understood the operating instructions and the system manual. Important! Prior to use, read the operating instructions and the system manual and keep these in a safe place. Ensure the operating instructions and the system manual are always available during mounting, setup and servicing. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage period required. For this reason you should archive a printed copy of the system manual. If you should lose the operating instructions or the system manual, you can download these documents from www. EUCHNER.de.



System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Function Together with a handle module, the locking module makes it possible to lock moveable safety guards. The combination also serves as a mechanical door stop at the same time. Important! To operate the device as a guard lock according to EN 1088, the signals for door position (T), bolt position (R) and guard lock monitoring (Z) must be polled in a logical AND operator. This operator is already implemented in the safety bit SI10. As an alternative, you can also link the bits SI3 to SI5 individually in your control system. The following switch-on condition applies for safety bit SI10 (see also System status table and section PROFIsafe data bytes):

 Safety guard closed  Bolt tongue inserted in the locking module  Locking arm in locking position (guard lock monitoring) The locking module detects the position of the safety guard and the position of the bolt tongue. The position of the locking arm is also monitored. The bolt tongue in the handle module is retracted and extended by actuating the door handle. When the bolt tongue is fully inserted in the locking module, the locking arm locks the bolt tongue in this position. Depending on the version, this locking is by spring force or solenoid force.

Version MGB-L1B-... The locking arm is kept in locked position by spring force and is unlocked by magnetic force (closed-circuit current principle).

Version MGB-L2B-... The locking arm is kept in locked position by magnetic force and unlocked by spring force when the solenoid is switched off (open-circuit current principle). Warning!

 The safety guard can be opened immediately in the event of interruption of the solenoid power supply!

 Usage only in special cases in accordance with strict evaluation of the accident risk (see EN 1088:1995+A2:2008, section 5.5). Typical case: If the risk of accidental locking inside a safety guard during a power failure is higher than the risk of ineffective guard locking.

System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Protection against environmental effects Lasting and correct safety function requires that the system must be protected against foreign bodies such as swarf, sand, blasting shot, etc. which can become lodged in the locking and handle modules. For this purpose a suitable installation position should be selected. Cover device during painting work!

Electrical connection Warning! Installation must be performed only by authorized personnel. Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection.  All the electrical connections must either be isolated from the mains supply by a safety transformer according IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures.  For use and operation as per the requirements, a power supply with the feature "for use in class 2 circuits" must be used. The same requirement applies to the safety outputs. Alternative solutions must comply with the following requirements: a) Electrically isolated power supply unit with a max. open-circuit voltage of 30 V/DC and a limited current of max. 8 A. b) Electrically isolated power supply unit in combination with fuse as per UL248. This fuse should be designed for max. 3.3 A and should be integrated into the 30 V/DC voltage section. Attention!

 The supply for further subscribers on the bus may be forwarded via the Euchner MGB system. The entire supply current through the MGB must not be higher than specified in the section Technical data.  The function earth must be connected. An M6 threaded bore is available on the mounting plate for this purpose. Important!

 If the device does not appear to function when operating voltage is applied (e. g. UB LED does not illuminate), the safety switch must be returned unopened to the manufacturer.  To ensure the stated degree of protection IP67 is achieved, the cover screws must be tightened to a tightening torque of 1 Nm.  Tighten screw for the cover for the mechanical release to 0.5 Nm.

 The electrical connection is established via push-pull plugs according to IEC 61076-3-117 variant 14 (for connector assignment see Figure 11).

Ethernet connection on bus module The bus module includes a PROFINET RT switch for Ethernet connection (see Figure 11).

System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Setup Integrating into PROFINET and PROFIsafe Attention! The parameters "Update time" and "F-WD-Time" have a decisive effect on the reaction time of the safety function. The safety function could be lost if the reaction times are too long. Important! You will require the corresponding GSD file in GSDML format in order to integrate the MGB system:

 GSDML-Vx.x-EUCHNER-MGB_110026-YYYYMMDD.xml You can find the GSD file in the download area at www.EUCHNER.de. Prior to commissioning, the GSD file must be imported into the configuration software of the control system (see control system manual). You must perform the following steps to integrate the MGB system into PROFINET. 1. Configure the MGB system with the configuration software of the control system and assign parameters. The following PROFINET parameters must be set:

 Device name (factory setting from GSD file): [euchnermgb].  IP address: optionally fixed or dynamic  Update time

Recommendation [32 ms] Max. value [128 ms] (with number of repeat cycles = 3)

The following PROFIsafe parameters must be set:

 F_dest_adr (PROFIsafe address): this is automatically assigned by the control system as a rule.

 F_WD_Time (time during which the control system expects a response by the PROFIsafe device): [xxx ms]. Factory setting from GSD file: (600 ms)

. Set the PROFIsafe address (F_dest_adr) on the MGB system using the DIP switches (see Figure 11). Important: Identical addresses must be set in the control system and on the device. . Save the configuration and transfer it to the MGB system.

15

System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Replacement of an MGB system without programming device If servicing is required, the MGB system is easy to replace with a new one. For this purpose the following prerequisites must be met:

 The DIP switch settings on the new device must match those on the old device.

 Your Profinet master must support the automatic replacement of Profinet subscribers.

 Your Profinet topology must be correctly configured.  There must not be a device name in the MGB system.

This field is blank in the default setting on delivery. Systems that already contain a name must first be reset to the factory settings.

Once these conditions are met, simply replace the old system with the new system. The Profinet bus does not need to be switched off for this purpose.

System reset to factory settings You will find detailed instructions in the manual for the configuration software for your control system.

16

System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Teach-in operation The handle module must be assigned to the locking module using a teach-in function before the system forms a functional unit. During a teach-in operation the system is in the safe state (bit SI10 is not set). Important!

 The locking module disables the code for the previous handle module if teach-in is carried out for a new handle module. Teach-in is not possible again immediately for this module if a new teach-in process is carried out. The disabled code is deleted in the locking module only after a third code has been taught.  The locking module can only be operated with the last handle module taught.  If, in the teach-in standby state, the locking module detects the handle module taught-in or a disabled handle module, the teach-in standby state is ended immediately and the locking module changes to the normal state.  If the bolt tongue is in the operating distance for less than 60 s, the handle module is not taught.

Teaching in handle module 1. Fit handle module. . Close safety guard. Check for correct alignment and distance using the marking on the locking module and re-adjust if necessary. . Insert bolt tongue in the locking module. 4. Apply operating voltage to the locking module.

 Teach-in process starts, green LED (DIA1) flashes slowly (approx. 2 Hz). The

teach-in standby state is active for 3 minutes after switch on. During teach-in, the locking module checks whether the handle module is a disabled handle module. Provided this is not the case, the teach-in operation is completed after approx. 60 seconds, and the green LED (DIA1) goes out. The new code has now been stored, and the old code is disabled.

5. Reset via bit O18 to activate the handle module's code from the teach-in operation in the locking module.

Mechanical function test It must be possible to easily insert the bolt tongue in the locking module. To check, close safety guard several times and actuate door handle. If available, check function of the escape release. It must be possible to operate the escape release from the inside without excessive effort.

17

System Manual Safety System MGB-L1B-PNA-.../MGB-L2B-PNA-... (PROFINET)

Electrical function test 1. Switch on operating voltage or reset using output bit O18. . Close all safety guards and insert the bolt tongue into the locking module. In the case of guard locking by solenoid force,  activate guard locking.

 The machine must not start automatically.  It must not be possible to open the safety guard.  The yellow STATE LED illuminates continuously. . Enable operation in the control system.

 It must not be possible to deactivate guard locking as long as operation is enabled.

4. Disable operation in the control system and deactivate guard locking.

 The safety guard must remain locked until there is no longer any risk of injury.  It must not be possible to start the machine as long as the guard locking is deactivated.

 It must be possible to open the safety guard. Repeat steps 2-4 for each safety guard.
