Features
The TG-EL-D4B can monitor tank volume (gallons or liters) and tank leak detectors for one or two tanks via
8 Intrinsically Safe inputs.
Fully field-configurable: The TG-EL-D4B can be completely configured in the field from its touchscreen menus.
A laptop with D4B_Edit software can also be used to configure the D4B via the USB port.
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 D4B can print a stick chart for either dimension-based or manual stick chart-based calculations.
Delivery detection and Data Logging: The TG-EL-D4B automatically detects a delivery and stores the delivered volume in a
time/date-stamped data-logger nonvolatile memory. The most recent 50 Deliveries are saved.
The printer can be configured to automatically print a time/date-stamped “Volume Delivered” report after each delivery that can be used
to verify the invoice before payment. The complete delivery history can also be viewed from the TG-EL-D4B screen, or read via USB into
D4B_Edit.
Usage monitoring and Data Logging: Every day at midnight, the TG-EL-D4B 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. Usage less than
(0.1% of Full Tank volume) or (Idle Tank Volume Change Theft SP) is considered to be 0 usage for the day. This prevents nuisance
usage due to fluid thermal expansion/contraction.
The resulting daily usage is date-stamped and stored in the data-logger nonvolatile 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 touchscreen menus, or read by Modbus.
For a single-tank system, the D4B stores the last 70 days and the last 52 weeks usage for the tank.
For a dual-tank system, the D4B stores 70 total usage records, so typically 35 days and 26 weeks for each tank.
On Demand HD-A2-C Leak Detector Test: The user, or an inspector, can initiate an HD-A2-C test from the display menu. If the printer
option is installed a time/date stamped pass/fail report will be printed.
Daily Automatic HD-A2-C Leak Detector Testing and Data Logging: Every Day at midnight, all HD-A2-C Leak Detectors are
automatically tested. If any Fail, the Manual Reset Leak Alarm is activated. The last 70 pass/fail results for each HD-A2-C, and the
channel(s) that failed is stored in the data logger.
Flexible, multipurpose Intrinsically Safe (I.S.) inputs: Each of the eight I.S. input channels can be connected to either a two-wire 4-20
mA transmitter or a contact closure. A wide variety of ullage, depth, head, discriminating leak, leak switch, fill alarm level switch, fill alarm
silence PB switches and sensors can be field-configured from the TG-EL-D4B menus to be connected to any one of the eight I.S. input
channels.
Selection of a standard Preferred Utilities sensor also configures the 4-20mA engineering units. Other I.S. 4-20 mA transmitters can also
be used with manually entered 4-20mA engineering units.
RS485 and Ethernet Modbus: The current depths, volumes, alarms, and statuses can be read via Modbus. The previous day delivery
and usage data can be read via Modbus. See the table at the end of the manual for Modbus addresses.
Custom Names: The touchscreen allows the user to enter a 12 character Name for each of the 15 Inputs. Each Tank also has a user
entered Name. These Custom Names appear on all Operator screens, Alarms, and Alarm History screens.
However, the Configuration/Setup menus used during installation the TG-EL-D4B refer to “Tank A” and “Tank B”.

Instruction Manual SDI-TG-EL-D4B-xx-x-0 page 5 of 38 Revised 3/8/22
Preferred Utilities Manufacturing Corporation Firmware 1.06
Alarms & Status’s:
The TG-EL-D4B can be configured to generate a wide variety of alarms. Alarms are time and date-stamped and then stored in the
data-logger nonvolatile memory. The alarm history can be printed, viewed on the touchscreen, or read into D4B_Edit PC software. The
TG-EL-D4B stores the last 50 alarms and events.
Over Fill alarms (FILALM x and OFIL-LK C): Typically an outdoor bell and light (FA-AV-xD3, or equal) are installed near the tank fill
pipe to warn the driver to stop filling the tank before it overfills.
For each tank, any, or all, of these signals/sensors can affect the outdoor bell:
Level Sensor HI Volume Setpoint (HI SP) TG-EL-WF, TG-EL-HLT, or other 4-20mA level sensor
Level Sensor HIHI Volume Setpoint (HIHI SP) TG-EL-WF, TG-EL-HLT, or other 4-20mA level sensor
Tank high level float switch (FILALM LS) HLS, PLS, or other float switch
Vent Pipe float switch (VENT LS) RBS, or other float switch
Leak Sensor (LK HD-A2, LK CONTAC) HD-A2-C, RBS, HLS, PS-LDS, or other
The FILALM x output rings the outdoor bell when: HIHI SP is exceeded, or FILALM LS or VENT LS is active.
The OFIL-LK C output rings the outdoor bell when: HI SP or HIHI SP is exceeded, or FILALM LS, VENT LS, or any Leak Sensor
(HD-A2-C or LK CONTAC) is active for either tank.
The outdoor FilAlarm bell can be silenced by the driver if an outdoor pushbutton is wired to an FILALM AS input, or it will automatically
silence after 60 seconds (adj. 10-120 sec.). Before filling the tank, the driver can test the fill alarm by pressing and holding the outdoor
alarm silence button for more than five seconds.
The FilAlarm output (bell) will re-activate every time any of the related signals activates.
FILALM x output example: Volume > HIHI SP, bell sounds, bell silences (Driver or Auto Silence), tank keeps filling, FILALM LS tank level
switch activates, bell sounds, bell silences, tank keeps filling, VENT LS vent pipe switch activates, bell sounds. The OFIL-LK output
responds similarly, but for more sensors.
The Outdoor light is typically activated by the HIHI x ST output, which energizes if Volume > HIHI SP, FILALM LS, or VENT LS is active.
For dual-tank systems, individual (or common) lights, bells, alarm silence buttons and/or bells can be used, provided enough outputs are
available.
Overfill Alarms do not trigger the D4B local alarm beeper or ALARM COM output, and are not recorded in the Alarm History. However, HI
and HIHI Volume alarms are data logged.
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 D4B 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 normal peak flow rate is known and that the theft
is caused by a high flow rate removal of oil by a pump.

Instruction Manual SDI-TG-EL-D4B-xx-x-0 page 6 of 38 Revised 3/8/22
Preferred Utilities Manufacturing Corporation Firmware 1.06
Other 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. Status functions do not trigger the alarm outputs.
Almost all alarms reset/silence automatically when the condition clears. A Leak alarm will stay in alarm until the the Leak signal returns
to normal and is then Reset by the Operator. The Low-Low level alarm can be configured as either manual reset or auto reset. The
ALARM COM output can be silenced either from the faceplate Alarm Silence button, or from a COMMON AS input from an external
pushbutton.
There are four user-adjustable volume setpoints for each Tank (total of eight), and one alarm delay seconds parameter:
HIGH-HIGH, HIGH, LOW, LOW-LOW
Each setpoint is used by both an alarm function and a status function, and sometimes by other functions.
The setpoint name describes the logic, examples:
HIGH-HIGH setpoint: If the volume is higher than the HIGH-HIGH setpoint for more than the alarm delay seconds, outputs configured as
either HIHI x AL or HIHI x ST are triggered.
LOW setpoint: If the volume is lower than the LOW setpoint, LO x AL and LO x ST outputs are 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.
Any Alarm or Status can energize any output. The user configures each output to respond to the desired Alarm or Status. Multiple
outputs can be configured to respond to the same Alarm or Status. See the ROUT/DOUT CONFIG menu.
Printer:
The TG-EL-D4B-EP-0-0 includes a printer and is pre-mounted in a wall mount enclosure.
The TG-EL-00-0-0 and TG-EL-E0-0-0 does not include a printer. The TG-EL-D4A-PRINTER can be purchased separately, mounted in a
user provided enclosure.
The following printed reports are provided:
Short report includes for each tank: current depth and volume; previous day’s usage; last delivery and the
most recent HD-A2 test result; and the last 10 alarms.
Long report includes everything on the short report, plus: the 10 latest deliveries for each tank, the last 8 daily consumptions for
each tank, and the last 5 weekly consumptions for each tank.
Stick Chart report shows the volume at various depth intervals, one tank per report (maximum of 50 evenly spaced depths, plus the
full volume and depth).
Any of the above reports can be printed at any time by the operator via the touchscreen PRINT button if the printer option is enabled.
In addition, reports can be configured to automatically print based on the following events:
Every Midnight: Disable, Short Report, Long Report
Every Sunday Midnight: Disable, Long Report
After Any Alarm: Disable, Short Report
After a Delivery: Disable, Long Report
If the printer is not installed, all data logged data can also be extracted with the D4B_Edit Windows PC App for viewing and saved in a
.csv format for easy integration into a spreadsheet.

Physical Installation
WARNING
Failure to comply with Control drawing 190789, and the instruction
manuals of all Intrinsically Safe sensors connected to the TG-EL-D4B,
voids the Intrinsically Safe design and creates an explosion risk in
the hazardous area.
TG-EL-D4B-00-x-x is designed for flush mounting in an enclosure.
TG-EL-D4B-Ex-x-x is pre-mounted in an enclosure.
The TG-EL-D4B should be mounted in a non-hazardous, indoor, NEMA 12
location that is free from excessive vibration. It is rated for continuous operation
over the 32º F-122º F (0º C-50º C) range.
The optional printer is rated NEMA 1 and should not be exposed to mists or
sprays.
Read all of the Intrinsic Safety (I.S.) requirements on drawing 190789 and in the
Wiring section before mounting the TG-EL-D4B.
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 I.S.-vs.-non-I.S. separation must be maintained both inside the panel that the
TG-EL-D4B is mounted in and outside the panel, all the way to the tank sensors.
See the sketches below for conduit entry locations and internal wire routing paths that will maintain the 2" minimum separation between
I.S. and Non-I.S. wiring.

Wiring
NOTE:
Do NOT begin to wire the TG-EL-D4B or the sensors unless the
TG-EL-D4B 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 comply with Control drawing 190789, and the instruction manuals of all Intrinsically
Safe sensors connected to the TG-EL-D4B, voids the Intrinsically Safe design and creates 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-D4B-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-D4B Control Drawing 190789 (next page) and all requirements on the
control drawings of all associated apparatus in the hazardous location that is wired to the TG-EL-D4B terminals 21, 22, 51 through 70.
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 21 and 22 are an essential part of the Intrinsic Safety design of the TG-EL-D4B. Two
separate, independent, I.S. ground wires must be run from terminals 21 and 22 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 190789.
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, of either 92612 or 26000 cable satisfies drawing 190789 I.S. capacitance and inductance requirements when
wired from from any TG-EL-D4B-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 any simple switch.
"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-D4B).
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-D4B.
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.
WARNING
Connecting Non-Intrinsically Safe devices to any Intrinsically Safe terminal voids the Intrinsically Safe
design and creates an explosion risk in the hazardous area

NOTES:
1. ‘Electric Code’ means: ANSI/NFPA 70 National Electrical Code, or Canadian Electrical Code, or Local installation Codes, as applicable.
2. Control equipment connected to the TG-EL-D4B-xx-x-x must not use or generate more than 250 Vac or Vdc with respect to earth.
3. The Capacitance and Inductance of the field wiring cable from the TG-EL-D4B to the Intrinsically Safe Apparatus must be calculated and
included in the calculations in Note 4. Ccable = Cable Capacitance for the installed length, Ci = Intrinsically Safe Apparatus Internal
Capacitance (marked on the device), Ca = TG-EL-D4B Max Allowed Connected Capacitance (see above). The same descriptions apply
for inductance: Lcabl e , Li , and La . If the cable capacitance and inductance per foot is not known, use: Ccable = 0.00006 uF/foot and
Lcable = 0.0002 mH/foot.
4. Third Party Listed, Entity Rated, Intrinsically Safe Apparatus can be connected to TG-EL-D4B terminals 51 - 70 IF it is suitable for the
application AND it is installed in accordance with the manufacturers instructions AND all wiring is in accordance with the
TG-EL-D4B-xx-x-x instructions AND it satisfies ALL of the following relationships:
Intrinsically Safe Apparatus Associated Apparatus (TG-EL-D4B-xx-x-x)
Vmax ( or Ui ) > Voc ( or Vt or Uo )
Imax ( or Ii ) > Isc ( or It or Io )
Pmax ( or Pi ) > Po
Ci + Ccable < Ca ( or Co )
Li + Lcable < La ( or Lo )
5. A Switch (with no added capacitance or inductance) is a Simple Apparatus and does not require Third Party Approval in order to be
connected to the TG-EL-D4B. See the Electric Code and ANSI/NFPA article 504.
6. The TG-EL-D4B-xx-x-x MUST be connected to a suitable ground electrode per the Electric Code. Resistance from the TG-EL-D4B-xx-x-x
Intrinsically Safe Ground terminals 21 and 22 to the AC Power Source Ground Electrode must be less than 1 ohm.
Two independent I.S. Ground wires (14 ga. Min.) must be run from the TG-EL-D4B to Ground (one to terminal 21, one to terminal 22).
7. Intrinsically Safe wiring from the TG-EL-D4B to the Intrinsically Safe Apparatus must remain physically separated from non-Intrinsically Safe
wiring by means of conduit, raceways, partitions, or tie-downs which permanently maintain at least 2" separation.
See the Electric Code and ANSI/NFPA article 504.
8. Multiple Intrinsically Safe circuits may be run in the same conduit or raceway IF the total insulation thickness separating conductors of
different circuits is at least 0.020" (0.50mm). See ANSI/NFPA 70 article 504.
9. Special Note for Model TG-EL-D4B-00-0-0:
The TG-EL-D4B-00-0-0 must be installed in an enclosure suitable for the application in accordance with the NEC.
10. WARNING: No User serviceable Parts. Return to factory for all repairs.

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.
Head is the pressure at the bottom of the tank caused by the weight of the
fluid above it. Head sensors measure this pressure in "Inches of Water
Column" or in "Centimeters of Water Column" units.
Actual depth = ("WC x Specific Gravity) + Depth Adj.
The specific gravity is entered via the TANK x SIZING menu.
