Features The TG-EL-D4A can monitor tank volume (gallons or liters) and tank leak detectors for one or two tanks via 10 inputs (six Intrinsically Safe inputs and four auxiliary). Flexible, multipurpose Intrinsically Safe (I.S.) inputs: Each of the six I.S. input channels can be connected to either a two-wire 4-20 mA xmtr or a contact closure. A wide variety of ullage, depth, head, flow, discriminating leak, leak switch, fill alarm level switch, fill alarm silence PB switches and sensors can be field-configured from the TG-EL-D4A menus to be connected to any one of the six I.S. input channels. The 4-20 mA engineering units for the standard Preferred Utilities sensors are preloaded and automatically entered when one of these sensors is assigned to an input channel. Other I.S. 4-20 mA xmtrs can also be used (with manually configured engineering units). Fully field-configurable: The TG-EL-D4A can be completely configured in the field from its LCD menus. A laptop is not required to configure the TG-EL-D4A. Gallons (or liters) volume calculation based on: a) One of five standard tank shapes with user-entered tank dimensions (inches or centimeters), or b) A user-entered volume-vs.-depth stick chart (up to 51 points), typically from tank mfg. stick chart data. The D4A can print a stick chart for either dimension-based or manual stick chart-based calculations. Delivery detection and data logging: The TG-EL-D4A automatically detects a delivery and stores the delivered volume in a time/date-stamped data-logger nonvolatile memory. For a dual-tank system, the last seven deliveries for each tank are stored. For a single-tank system, the last 14 deliveries are stored. The printer can be configured to automatically print a time/date-stamped “Gallons Delivered” report after the delivery that can be used to verify the invoice before payment. The complete delivery history can be viewed from the TG-EL-D4A LCD screen and is also available via Modbus. Delivery verification and shortage detection: With the high price of oil, it is important to pay for only what is actually delivered. The delivery data logging and reports are the first level of verification. This is accomplished with a single fluid-depth sensor per tank. If a secondary sensor is installed, the D4A provides more sophisticated verification. The D4A supports three primary/secondary sensor combinations: Level (primary)/head (secondary) Level (primary)/flow (secondary) Head (primary)/flow (secondary) A level sensor directly measures the fluid depth with TG-EL-WF wire float, ultrasonic, float-based magnetostrictive sensors, and others. A flow sensor is installed in the delivery pipe and directly measures the delivered fluid volume. A head sensor measures the weight (pressure) of the fluid at the bottom of the tank, calculates the fluid depth based on a user-entered specific gravity and then calculates the volume based on the derived depth. Head sensor-based volume is generally less accurate than level- or flow-based volume. The level/flow or head/flow combinations compare the tank volume difference before and after the delivery with the flow meter-measured volume. If the volume difference is larger than the user-adjusted threshold, the D4A notes the difference on the printed delivery report and records the difference in the alarm history (but does not trigger the alarm system). The level/head combination cross-checks a volumetric measurement against a weight-based measurement. Delivery “shorting” by air injection, or by waste fluid blending, changes the delivered oil density (i.e., specific gravity) and “fools” both the truck delivery meter volumetric measurement and level-based tank volume calculations, even with the most precise sensors.

Revised 1/19/11

Delivery verification and shortage detection (continued): The head sensor responds to fluid weight and will detect a “light” oil delivery due to air injection, or a “heavy” oil delivery due to waste oil blending. The TG-EL-D4A uses specialized head sensor compensation calculations at the time of each delivery to enhance the detection of specific gravity changes and notes a suspicious oil-density change on the “Gallons Delivered” printed report and in the alarm history (but does not trigger the alarm system). Usage monitoring and data logging: Every day at midnight, the TG-EL-D4A computes the usage for the previous day based on: tank volume at the previous midnight, the sum of all deliveries during the day, and the tank volume at the current midnight. The resulting daily usage is date-stamped and stored in the data-logger EEPROM memory. Every Sunday at midnight, the previous seven days are added together and stored as the weekly usage. The oldest data are overwritten by newer data. Usage data can be printed, viewed via the LCD menus, or read by Modbus. For a dual-tank system, the D4A stores the last seven individual days and the last four weeks’ usage for each tank. For a single-tank system, the D4A stores the last 14 individual days and the last eight weeks’ usage for each tank. Alarm history data logging: The TG-EL-D4A can be configured to generate a wide variety of alarms. Alarms are time- and date-stamped and then stored in the data-logger EEPROM memory. The alarm history can be printed, viewed via the LCD menus, or read by Modbus. The TG-EL-D4A stores the last 10 alarms regardless of how many tanks are configured. Theft alarm: Thefts are monitored in two ways: idle tank volume change and high usage rate. Idle tank: An idle tank will trigger a theft alarm if the volume drops an adjustable amount below the volume saved at the time the tank became idle. This mode requires a contact closure input that indicates when the tank is idle. This could be a manual valve auxiliary switch, a pump starter auxiliary switch, a flow switch, a diesel generator “not running” contact, or other means. High usage: The D4A monitors the tank volume every few minutes and calculates a short-term usage rate. If this rate is higher than a user-adjustable theft rate, a theft alarm will be triggered. This strategy assumes that the peak usage rate is known and that the theft is caused by a rapid, higher flow rate, or removal of oil. Fill alarm: When the tank is being filled and the volume exceeds the high-high volume setpoint, the TG-EL-D4A can be configured to activate a relay output. This, in turn, can activate an FA-AV-x-D3 (or similar) audible/visual fill alarm near the tank fill pipe to warn the driver to stop filling the tank before it overfills. This alarm self-silences after an adjustable time delay, or it can be manually silenced. The driver can test the fill alarm by pressing and holding the remote alarm silence button for more than five seconds. If the tank is not full, this test will trigger the fill alarm relay output. “Not Full” means the volume is lower than the high-high volume setpoint and the FILALM LS input is inactive (if configured). For dual-tank systems, the D4A can be configured for an individual fill alarm per tank, a common fill alarm for both tanks, individual or common fill alarm silence/test buttons, or any combination of individual/common devices. A fill alarm is not recorded in the alarm history, does not trigger the D4A, and does not cause the D4A bar graph to blink. The fill alarm is intended only to alert the tank truck driver. If these features are desired, enable the high-high alarm feature for the tank. A remote visual light for “Tank Full” indication can be implemented by configuring one of the relays as a highhigh status relay. HD-A2-C discriminating leak alarms: HD-A2-C leak sensor inputs to the TG-EL-D4A can discriminate among the following conditions: dry, oil present, water present, shorted field wiring, and open-circuit field wiring. Any condition other than “dry” will trigger a leak alarm for that channel and be recorded in the alarm history with the channel number and the condition. Any type of leak alarm requires a manual reset after the condition has been cleared. Instruction Manual SDI-TG-EL-D4A-xx-x-0 Preferred Utilities Manufacturing Corporation

Revised 1/19/11

HD-A2-C continuous self-test, daily test, and manually initiated test: All leak-detection systems must be periodically tested over the 20- to 30-year life of the tank to ensure that the leak-detection system will work if/when a leak occurs. The HD-A2-C continuously does self-tests, including testing the critical wet/dry light source and detector, and will change its output to non-dry if a problem is detected. Every midnight, the TG-EL-D4A commands all HD-A2-Cs to do a self-test and then tests each HD-A2 to determine if its output is falsely “stuck” at the “dry” output signal. This test also can be initiated at any time by an inspector from the main menu. Contact closure leak sensor field Wiring Fault Test Network (WFTN): Contact closure leak sensors open or close an internal switch contact to signal a leak or no-leak condition. Field wiring faults can prevent leak detection. An open circuit in the field wiring of a N.O. (normally open) leak sensor prevents leak detection. A short circuit in the field wiring of a N.C. (Normally Closed) leak sensor prevents leak detection. Installation of a WFTN (Wiring Fault Test Network) in the junction box of a contact closure leak sensor allows the TG-EL-D4A to continuously discriminate among these four conditions: no leak, leak, wiring open, or wiring short. Any condition other than “no leak” will trigger a leak alarm for that channel and be recorded in the alarm history with the channel number and the condition. Any type of leak alarm requires a manual reset after the condition has been cleared. Alarm and status functions: In addition to the fill alarm, theft alarm, and leak alarms discussed above, each tank has four volume-based alarm functions, four volume-based status functions, and two volume-based control functions. Alarm and status functions are very similar. The differences between an alarm and a status are: Feature Alarm Status Triggers the common alarm yes no Causes the bar graph to blink yes no Silenced by the various alarm silence signals yes no Creates a time/date-stamped alarm history entry yes no Can be disabled via the configuration menus yes no Adjustable time delay (one adj. for all alarms) yes no Automatically resets after condition clears depends yes Turns on a Modbus coil yes yes Can be configured to energize an output relay yes yes There are eight user-adjustable volume setpoints and one alarm delay seconds parameter: HIGH-HIGH T1, HIGH T1, LOW T1, LOW-LOW T1, HIGH-HIGH T2, HIGH T2, LOW T2, and LOW-LOW T2. Each setpoint is used by both an alarm function and a status function, and sometimes by other functions. The setpoint name describes the logic: HIGH-HIGH setpoint: If the volume is higher than the HIGH-HIGH setpoint for more than the alarm delay seconds, a HIGH-HIGH alarm is triggered. HIGH-HIGH setpoint: If the volume is higher than the HIGH-HIGH setpoint, a HIGH-HIGH status is triggered.. LOW setpoint: If the volume is lower than the LOW setpoint, a LOW status is triggered. Other setpoint uses: The HIGH-HIGH setpoint triggers the fill alarm function described above. FILL function: If volume < LOW setpoint, FILL turns ON. If volume > HIGH setpoint, FILL turns OFF. If both conditions are true, FILL turns OFF. DRAIN function: If volume > HIGH setpoint, DRAIN turns ON. If volume < LOW setpoint, DRAIN turns OFF. If both conditions are true, DRAIN turns ON.

None of the alarms or statuses energizes any particular relay output channel. The six output relays are energized by the alarm or status function selected by the user during configuration. See the RELAY CONFIG menu. RS485 Modbus: The current depths, volumes, alarms, and statuses can be read via Modbus. The last 10 alarms and all of the delivery and usage data-logger data can be read via Modbus. See the table at the end of the manual. Printer: There are three printer reports: short, long, and stick chart. The short report includes for each tank: current depth and volume; volume, usage, and HD-A2 test results at previous midnight; last delivery; and all alarms that occurred within the last 24 hours. The long report includes for each tank: the 14 latest deliveries, the 14 last daily consumptions, the eight last weekly consumptions, and the last 10 alarms. The stick chart report shows the volume at various depth intervals, one tank per report. The depth interval is user-configured, with a maximum of 50 evenly spaced depths, plus the full volume and depth.

Wiring NOTE: Do NOT begin to wire the TG-EL-D4A or the sensors unless the TG-EL-D4A I/O Channel Configuration Worksheet has been completed and all of the Intrinsic Safety wiring and physical installation notes have been read.

WARNING Failure to follow all procedures in this manual, on drawing 190788, and in the instruction manuals of all Intrinsically Safe sensors connected to the TG-EL-D4A voids the Intrinsically Safe design and may create an explosion risk in the hazardous area.

Intrinsically Safe wiring notes: What is “Intrinsic Safety”? "Intrinsically Safe" (I.S.) means that when the TG-EL-D4A-xx-x-x tank gauge and compatible sensors are properly installed, the sensors and the field wiring in the hazardous area will be incapable of releasing sufficient energy to cause ignition of a Group C or D hazardous atmosphere. The installation must comply with the requirements of the TG-EL-D4A Control Drawing 190788 (next page) and all requirements on the control drawings of all associated apparatus in the hazardous location that is wired to the TG-EL-D4A terminals 51 through 65. Non-Intrinsically Safe devices may NOT be wired to terminals 51 through 65. The Intrinsically Safe wiring must remain physically separated from all other non-Intrinsically Safe wiring by means of conduit, raceways, partitions, or tie-downs. Tie-downs are acceptable if a 2" minimum separation is permanently maintained. The ground wires connected to terminals 50 and 66 are an essential part of the Intrinsic Safety design of the TG-EL-D4A. Two separate, independent, I.S. ground wires must be run from terminals 50 and 66 back to the grounding point of the AC power-supply system with less than a 1-ohm resistance. This wiring can NOT be electrically combined with any other AC ground wiring. Splices are not recommended. Follow all NEC and CSA codes for installation and marking of Intrinsically Safe wiring and grounding. The capacitance and inductance of the field wiring cable affects the Intrinsically Safe design as noted on Control Drawing 190788. Preferred p/n 92612 and 26000 cables are rated at less than 0.00005 uf/ft. and 0.0002 mH/ft. 1000-ft. cable runs, or less, satisfy the drawing 190788 I.S. requirements and the 4-20mA loop resistance requirements using either 92612 or 26000 cable from any TG-EL-D4A-xx-x I.S. input channel to any of the following: TG-EL-WF-7-C, TG-EL-WF-12-C, TG-EL-HLT-7-C, TG-EL-HLT-15-C, TG-EL-ULT-18-C, HD-A2-C, or WFTN-1. "Simple switches" are inherently Intrinsically Safe and do not require UL, FM, CSA, or other approvals to be used in a hazardous location when connected to an Intrinsically Safe associated apparatus (the TG-EL-D4A). A "simple switch" is a mechanically actuated electrical contact that does not have any other electrical components (especially no added capacitance and no added inductance). A simple switch does not store or discharge any electrical energy. All electrical energy is provided by, and limited by, the I.S. design of the TG-EL-D4A.

Non-Intrinsically Safe wiring notes: Do not run low-voltage DC wiring bundled with, or in the same conduit as, AC wiring. Ground DC shielded cables only where shown. Insulate exposed shields to prevent connections to ground.

When the SENSOR TYPE is changed, the calibration is changed automatically to the above defaults. The default calibration data for sensors LVL OTHER, HEADOTHER, and LVL UL18 must be changed by the user to reflect the calibration of the sensor being used. The calibration data for SENSOR TYPES: LVL WF7, LVL WF12, HEAD HL7, and HEAD HL15 should not be changed and must be set to the above default values. The default units are: IN-GALLON (inches-gallons). Units can be changed to CM-LITER (centimeters-liters) via the UNITS selection in CONFIGURE MENU. If CM-LITER units are used, the 20 mA calibration must be changed manually to the equivalent cm values in the table above via the INPUT X SENSOR CONFIG menu. Fluid depth methods Ullage is the distance from the top of the tank down to the top of the fluid. Actual depth = (tank full height – ullage) + depth adj. Depth is the distance from the top of the fluid down to the bottom of the tank. Actual depth = xmtr depth + depth adj.

Fluid depth methods

(continued)

Depth Adjust is provided to correct deviations caused by mounting height errors, sensor body sizes, … etc. Examples: The TG-EL-HLT-7-C sensor body is 1" diameter. When it lies on the bottom of the tank, the pressure port is 0.5" above the bottom of the tank. Set Depth Adjust to +0.5" to compensate. If the TG-EL-WF-7-C tank mounting flange is the incorrect height, or if the float is in the wrong position on the wire, the Depth Adjust setting can be used to correct these errors.

"Stick depth" is the depth displayed on the face of the TG-EL-D4A and in the VIEW I/O troubleshooting screen. Stick depth = (actual depth – striker plate thickness)

TG-EL-WF-x-C 'Wire Float' Level Sensor

Stick for Manual Tank Level Measurement

The fluid depth measured with a stick ("stick depth") is typically less than the actual fluid depth because of the thickness of a “striker plate” at the bottom of the tank. Striker plates are installed by tank manufacturers to prevent damage caused by repeatedly dropping the stick into the tank and are typically 5/16" thick (0.31"). See tank mfg. drawing for actual thickness. Most tank mfg. "stick charts" show fluid volume versus stick depth. Therefore, the TG-EL-D4A displays the "stick depth" to the user.

Fluid Level Stick Depth

Actual Depth

The default striker plate thickness = 0.3". It is adjusted in the TANK x SIZING MENU. Setting the thickness to 0.0" makes the D4A "Striker Plate" display actual depth. Striker plate thickness must be manually changed to the equivalent centimeters (0.8 cm is 5/16") if the units are changed to CM-LITER. For maximum accuracy, "actual depth" is used in the D4A internal volume calculations for the of standard tank shapes and LIN/VERT. However, "striker depth" is used internally for STIKCHRT volume calculations.

Revised 1/19/11

Tank Dimensions and Stick Chart Types The STICK CHART TYPE that is selected determines how the TG-EL-D4A calculates the tank volume (gallons or liters) based on the fluid depth. Stick chart type choices include: FLAT HORZ (horizontal cylinder with flat ends): Volume is calculated based on: actual depth, the dimensions entered and the tank shape. The user does not enter stick chart volume versus depth data points. DISH HORZ (horizontal cylinder with dished ends ): Volume is calculated based on: actual depth, the dimensions entered and the tank shape. The user does not enter stick chart volume versus depth data points. V OBROUND (vertical “obround” tank): Volume is calculated based on: actual depth, the dimensions entered and the tank shape. The user does not enter stick chart volume versus depth data points. Multiple tanks can be headered together with equalizing piping; simply enter the number of tanks headered together. H OBROUND (horizontal 'obround' tank): Volume is calculated based on: actual depth, the dimensions entered and the tank shape. The user does not enter stick chart volume versus depth data points. Multiple tanks can be headered together with equalizing piping; simply enter the number of tanks headered together. LIN/VERT (linear tank with straight, vertical walls and flat bottom): The horizontal cross-section shape and dimensions must be the same from bottom to top. Cross sections can be circular, square, rectangular, hexagonal, ... etc. Tank volume is directly proportional to actual depth. Based on the tank shape, the user must know and enter the tank FULL VOLUME at the tank FULL HEIGHT and must enter the tank FULL HEIGHT. The D4A does not calculate the full volume. It must be obtained from the tank manufacturer. STIK CHRT (stick chart-based): The D4A has a user-entered table with up to 50 volumes corresponding to equally spaced stick depths (user-entered DEPTH INTERVAL sets the spacing). The user must also enter the tank FULL VOLUME and the tank FULL HEIGHT. Typically this information is from the tank mfg. stick chart document. The D4A linearly interpolates the volume for depths in between the volumes entered and thus is somewhat less accurate than the other five stick chart types. Fewer than 50 points in the table are used when the DEPTH INTERVAL is increased. Example: 96.5" full height, 2.0" interval, 47 points used (empty and full don't use table points).

Head sensor specific gravity: If a HEAD HL7, HEAD HL15, or HEADOTHER sensor type is configured for this tank, then the specific gravity of the fluid must be entered in the TANK X DATA screens. Some specific gravities: Fluid Typical Range No. 1 fuel oil or kerosene 0.82 0.806 – 0.825 No. 2 fuel oil or diesel 0.876 0.825 – 0.887 No. 6 fuel oil 1.014 0.950 – 1.050 Note: No. 6 fuel doesn't really have a “typical” value; it varies substantially based on the point of origin. The resulting stick depth derived from the HEAD sensor signal is displayed as the next item in the menu. If the displayed depth does not appear to be correct, verify the specific gravity, sensor 20 mA cal, depth adj., and striker-plate thickness entries, and check to make sure the sensor is at the bottom of the tank

Delivery Detection Setup The TG-EL-D4A calculates the delivery volume by: Delivered volume = delivery “stop” volume – “initial” volume While waiting for a delivery, the D4A monitors tank volume and saves the lowest volume as the “initial” volume. To prevent false delivery detection, The D4A will declare only that a delivery is "in progress” if the volume has increased more than the user-adjusted START DELIVERY: VOLUME INCREASE value.

The VOLUME INCREASE value should be set high enough to prevent false delivery detection due to fluid thermal expansion, but lower than the smallest delivery volume anticipated. The default value is 100 gallons. The delivery is considered completed when the volume has not increased for SETTLING SECONDS (user-adjustable). This time delay should be long enough to allow the driver to drain the hose into the tank after stopping the delivery. The default time is 60 seconds.

NOTE: If the fuel from the tank is being burned/used while the delivery is in progress, the TG-EL-D4A will report a smaller delivery volume than actual delivery volume.

Delivery Verification Setup Delivery verification requires two sensors per tank, configured as primary and secondary via the INPUT CONFIG menu. The allowed combinations are: Level/Flow, Head/Flow, and Level/Head. After each delivery, the D4A compares the delivery volume reported by each sensor. If the difference between the two delivery volumes is larger than the user-adjusted GAL/LITER 2-SENSOR VERIFICATION ALARM, the difference is noted on the printed delivery report and also stored in the alarm history, but it does not actually trigger the alarm system. If a level/head sensor combination is installed: After a delivery, if the D4A determines that the measured before/after specific gravity has changed more than the user-entered SP.GRAV. CHANGE THRESHOLD, the difference is noted on the printed delivery report and also stored in the alarm history, but it does not actually trigger the alarm system.

Theft Alarm Setup Theft alarms are triggered either by an idle tank volume decrease or a short-term high-usage rate. Only one method is activated at a time. THEFT ALARM ENABLE TANK X must be set to “Enabled” to activate the theft alarm feature. If an IDLE TANK switch input is installed: When the IDLE TANK sensor changes from “Active” to “Idle,” the D4A saves the tank volume. It will trigger a theft alarm if the volume decreases more than the user-entered IDLE TANK VOL CHG THEFT SP TANK X gallons (or liters).

When the IDLE TANK sensor indicates the tank is active (or if this sensor is not installed), the D4A monitors the tank volume every few minutes and calculates a short-term usage rate (gpm or lpm). If the short-term rate is higher than the user-entered GPM/LPM FLOW RATE THEFT SP TANK X, the D4A will trigger a theft alarm. This value must be set higher than the peak tank usage rate to prevent false alarms.
