SECTION 3: INSTALLATION INSTRUCTIONS
Bennett Pump Dispensers are to be installed by trained technicians. All technicians must be aware of ALL safety instructions. If you are
not a Bennett trained technician, please contact Bennett Technical Support at 1-800-423-6638 for training information.
UNLOADING, UNPACKING AND PROPER STORAGE
Bennett dispensers are bolted to a pallet and then carefully packaged with cardboard/styrofoam liners and in a
cardboard exterior carton. The entire package is then securely wrapped with plastic shrink wrap. Use a fork lift to
transport the dispenser while it is still on the pallet.
Before signing the freight delivery receipt, inspect the carton and pallet for any obvious signs of damage to the
dispenser. If any damage is found with the product, instruct the delivery driver to make a notation on the delivery
receipt before signing. If possible, open the carton and inspect the dispenser before signing the delivery receipt.
Bennett dispensers are shipped F.O.B. This means that the title to the equipment passes to the purchaser at the
time the equipment is loaded on the truck at our factory. Freight damage claims are the responsibility of the
purchaser. Bennett will assist in preparing any damage claim, by helping to identify and price any parts
necessary to make needed repairs.
Carefully remove the plastic shrink-wrap from the carton. Then carefully remove the cardboard container and any
inside liners. DO NOT DISCARD THE PACKAGING. Should the need arise to repackage the dispenser, the
cardboard packaging can be reused. Plastic shrink-wrap can be purchased at office supply stores or industrial
packaging stores.
Examine the exterior panels for any signs of freight damage. If shipping damage has occurred after signing for
delivery, call the freight carrier immediately and request an inspection. DO NOT DISCARD THE PACKAGING;
the inspector will want to examine it.
If there is no freight damage to the exterior of the dispenser, use the door key (wire tied to the nozzle hook) to
unlock the upper door. Remove the lower panel from the dispenser. Visually examine the interior of the dispenser
for shipping damage. While the dispenser is extremely sturdy, a dispenser that has been “dropped” can suffer
damage internally even while it appears normal on the exterior.
Read the model/serial plate of the dispenser and check to confirm that the hydraulic configuration is what your
order specified.
Report any non-shipping related problems to Bennett Customer Service:
In USA, telephone [phone] or outside the USA, telephone [phone]; or via FAX to [phone];
or via email to [e-mail]. Or write to us at:
Bennett Pump Company
1218 E. Pontaluna Road
Spring Lake, Michigan, USA 49456
After freight inspection, it is extremely important to store the new dispensers in a heated building prior to
installation. Bennett factory test all units with de-ionized water prior to shipment. If stored in an environment that
is below freezing (32°F.), internal components will freeze or crystallize. This will cause damage to the internal
hydraulics at startup if these guidelines are not followed. Any damages related to improper storage are not
covered under the Bennett Limited Warranty for DEF dispensers.

ELECTRICAL FIELD WIRING- GENERAL INFORMATION
Electrical Wiring Section -
Find the wiring diagram specific to the dispenser model that is being worked on in the Wiring Diagrams section.
Read and follow all directions including supplemental notes contained on the drawing.
The dispenser’s field wiring connections are in the upper electronics head (electrical enclosure) of the dispenser.
Using the door keys shipped with the dispenser, (on nozzle boot) unlock the lock on the upper electronics enclosure
and open the door to access the wiring terminal on the CPU/ Control board. Field wiring will land on terminal strip
on base of electrical enclosure.
All field wiring must be stranded copper, oil and gas resistant (THHN) color coded, with a 600 volt insulation rating.
See wiring diagrams section for proper wire sizes. Pull 60” extra wire to reach the top of the dispenser. Do not use
wire nuts. The ends of the wires should be clean and free from oxidation.
Conduit for the field wiring must be 3/4”, rigid metal and continuous. The use of PVC conduit is not allowed. All
conduit between the building and each dispenser should be a separate conduit run.
Dispenser Electronic Power must be on a separate dedicated circuit breaker. Do not put submerged pump power
on this circuit breaker. Up to two dispenser may be placed on (1) 15 amp circuit breaker. No more than two
dispensers per 15 amp breaker. All dispensers at the station must be on the same phase of power.
All dispenser field wiring between the building and the dispenser for power, neutral and ground wire conductors
must not be spliced, wire nutted or shared with any other equipment. Doing so would void the Bennett Limited
Warranty. All power, neutral and ground conductors shall be run from the dispenser to the main service panel.
Electrical contractors must pull 60” of wire above the grade level to reach through the dispenser’s conduit
and into the electrical area at the top of the dispenser. Read and follow all instructions on the wiring
diagram and observe all national and local electrical codes.
In instances where new dispensers are replacing old dispensers, Bennett recommends new wiring be pulled to
each dispenser.
The maximum distance from the breaker panel to the dispenser is 500 feet.
WARNING: DO NOT CROSS PHASE REMOTE DISPENSERS OR DAMAGE WILL OCCUR. When installing more
than one dispenser the remote sub-pump relay control wire from each dispenser must be on the same phase of
power or cross phasing will occur at the sub-pump relay. This means that the electronic power for all dispensers
at the site must be on the same phase.
Electrical Conduits - Make sure that each dispenser has a dedicated electrical conduit. Wiring from multiple
dispensers in a single conduit is not allowed. All conduit should be rigid metal and drawn up tight. The use of PVC
(plastic) conduit is not allowed and will void the Bennett Warranty. Make sure any intercom wiring is not run with
dispenser field wiring. A separate (second) conduit must be run if intercoms are used near the dispenser.
PURGING PRODUCT LINES FOR REMOTE DISPENSERS

147193 Installation Manual DEF 100-200 Installation Introduction
11
Once product piping and tanks have been tested for leaks and any leak conditions have been fixed, and all electrical
connections have been made and verified, the remote dispenser product lines must be purged of all air that may
be trapped in the lines.
WARNING! Take appropriate measures to contain any product loss. Dispose of any spilled product in
a proper manner consistent with applicable laws and codes.
Use a test prover can or other appropriate approved container to dispense diesel exhaust fluid through the
dispenser. Begin dispensing by only slightly opening the nozzle to allow any entrapped air in the dispenser to slowly
release through the nozzle. This prevents over-speeding of the meter.
Once the dispenser has been purged of all air, the DEF meter should be tested for calibration. Refer to the
appropriate section in this manual for calibration procedures.
PURGING PRODUCT LINES FOR SUCTION PUMPS
Once product piping and tanks have been tested for leaks, any leak conditions have been fixed, and all electrical

through the conduit and into the upper electronic enclosure. Make sure that the copper ends of the wires are clean
and free of oxidation.
Electrical contractors must pull 60” of wire above the grade level to reach through the dispenser’s
conduit and into the electrical area at the top of the dispenser. Read and follow all instructions on the
wiring diagram and observe all national and local electrical codes.
PROPER EQUIPMENT GROUNDING
INSTRUCTIONS FOR EARTH GROUNDING THE EQUIPMENT
WARNING: Failure to properly ground the equipment can cause injury or damage to the equipment
and will void the Bennett limited warranty.
This product must be properly grounded. Each dispenser requires a 12-gauge Green earth ground wire. Grounding
provides a path of least resistance for electric current to reduce the risk of electric shock. Grounding is also required
to protect the dispenser’s computer from external electrical noise generating devices. The ground wire connection
must provide 1 ohm (or less) resistance to earth ground. To establish a good earth ground, follow this procedure:
1. Connect a 12-gauge (minimum), green stranded wire to the grounding terminal on the electronics enclosure
deck. Only one ground wire is required per dispenser.
2. Pull the wire through the rigid metal conduit and connect it directly to the ground bar of the MAIN electrical
service panel, not a sub-panel. Do NOT rely on the metal conduits as a ground anywhere in the system.
DO NOT USE WIRE NUTS ON GROUND WIRES. USE COMPRESSION CONNECTORS ONLY.
3. Do not daisy-chain ground wires. All ground circuits must be dedicated wires connected directly to the ground
bar in the main electrical panel. A direct connection to the site’s ground rod must be connected to the ground bar
in the main electrical panel.
AC POWER INSTALLATION
Each dispenser uses one 115V or 230V 50/60 Hz circuit for dispenser power. Make sure the power source has the
correct frequency and voltage. Connect the electrical circuit to the terminal strip on the CPU board or the terminal
block on the electronics deck. Only one dispenser electronics Hot and Neutral needs to be pulled per dispenser.
That power will be shared by the CPU and suction motor (if applicable).
Reference Note: L1 is hot and L2 is Neutral.
Electronic Power Connections: Remote
1. Connect the White (Neutral) 14ga. wire to terminal 2 of TS1 on the CPU board. The CPU board is located on
the upper electronics wall.
2. Connect the Black (Hot) 14ga. wire to terminal 3 of TS1 on the CPU board.
3. Dispenser power must be connected to a dedicated 15 amp. circuit breaker. Electronic power for all dispensers
at an installation must be wired to the same AC line phase or damage from cross phasing will result in the
remote sub-pump relay control circuits.
Electronic Power Connections: Self Contained Suction
1. Connect the White (Neutral) 14ga. wire to “NEUTRAL” on the terminal block. The terminal block is located in
the upper electronics enclosure.
2. Connect the Black (Hot) 14ga. wire to “L1” on the terminal block.

Rules to ensure proper operation:
1. Each dispenser uses one 115V or 230V circuit for dispenser power. Put no more than two (2) dispensers on a
circuit breaker.
2. Do not connect any other devices or motors to these circuits.
3. Put the pump wiring in a dedicated separate conduit. Do not put non-pump related wires, such as price signs
or intercoms, in the same conduit as pump wiring.
4. Use only 14-gauge stranded gas and oil resistant THHN wire.
5. Do not use wire nuts anywhere in the pump wiring runs.
WARNING: All Dispenser AC Power circuits (For Remotes Systems Only) must be on the same phase
or damage will result to the dispenser power board or the sub-pump relay box.
CONNECTING PUMP MOTOR POWER FOR REMOTE DISPENSERS
Remote dispensers require the use of submerged pumps. These pumps are located in the Underground Storage
Tank and are controlled by a “control relay”. The dispenser sends the signal to the control relay to energize the
submerged pump. Consult with the submerged pump manufacturer for more information on control relay boxes.
Connect the “Motor Out” power wire between the dispenser and the control relay box as follows:
Submerged Pump Motor Control —Connect to terminal 2 of TS2 located on the CPU electronics enclosure.
This should be a 14 ga. wire. It is recommended that the installer use a blue wire for submerged pump motor
control. Refer to the Remote Power Wiring Diagram section of this manual.
Note - Select Submerged Pump control or Suction Pump control by setting a jumper wire on the CPU. Make sure
that there is a jumper from P1 to P3 on the CPU if controlling a submerged pump relay. This will be set at the
factory.
CONNECTING PUMP MOTOR POWER FOR SUCTION SYSTEMS
Self-contained dispensers have the pump motor mounted in the lower hydraulic area. The power is passed to the
pump motor using the pump motor relay located on the CPU board in the electronic enclosure.
***Suction motor connections are pre-wired to the terminal block from the factory. Please refer to
the Self Contained Power Wiring Section of this manual.
Note - Select Submerged Pump control or Suction Pump control by setting a jumper wire on the CPU. Make sure
that there is NO jumper from P1 to P2 on the CPU board if controlling a suction pump motor. This will be set at the
factory.
CONNECTING THE COMMUNICATION WIRES
For the RS-485 communication wires, use 18 gauge, twisted wires at 8 twists per foot. Refer to the RS-485 Wiring
Diagram in the wiring section of this manual. Connect the RS485 communication wires to TS1 on the CPU
personality module as follows:
TS1 - 1 RS485 Positive (+) Orange 18 ga.
TS1 - 3 RS485 Negative (-) Brown 18 ga.

For the Current Looc Communication, use 18 Gauge THHN wires. Refer to the current loop wiring diagram in the wiring section of this
manual. Connect the Current Loop communication wires to TS1 of the CPU personality Module as follows:
TS1-1 Current Loop communication positive. (Orange)
TS1-2 Current Loop communications negative. (Yellow)
CONNECTING FIELD WIRING TO MECHANICAL PULSE OUTPUT
Mechanical Mode - Mechanical Mode allows the 200 series to imitate a mechanical dispenser and interface to a
fleet system. It also allows pulse output communication with a tank gauge.
Pulse Output - The pulse output allows the mechanical interface to send pulse information to the console and the
Tank Gauge. The system can be programmed to output pulse ratios from 1:1, 10:1, 100:1, and 1000:1. The Fleet
System connected to the dispenser must provide 5-12 volts DC for the pulse output channel. The pulse output rate
is determined with jumpers on the Pulse Output Board.
Refer to the Pulse Output Wiring Diagram in the back of this manual for details.
Handle Switch Signal—The handle switch signal can be used to signal the console that the pump is “in use”.
Some Fleet Systems require this signal and some do not. Refer to the Pulse Output Wiring Diagram in the back of
this manual to see how to wire the handle switch signals.
Authorization Signal - A Fleet System can send “authorization” to a fueling point (in the form of a 110 volt signal)
which allows the fueling point to reset at the beginning of the sale. Without this signal, the dispenser will not reset
when in the “Mechanical” mode. Refer to the Pulse Output Wiring Diagram in the back of this manual to see how to
wire the Authorization signals.
Tank Gauge Pulse Output Signals - The dispenser electronics Pulse Output Board can send pulse information to
the electronic Tank Gauge system so that it may reconcile dispensed product. The system can be programmed to
output pulse ratios from 1:1, 10:1, 100:1, and 1000:1. The Tank Gauge system connected to the dispenser must
provide 5-12 volts DC for the pulse output channel. Refer to the Pulse Output Wiring Diagram in the back of this
manual to see how to wire the Tank Gauge signals.
DISPENSER STARTUP AND CHECKLIST
CAUTION: To prevent damage to the dispenser, follow the proper start-up procedures.
Before applying AC power to the dispenser, follow this procedure:
1. Unlock and open the upper door and remove the lower dispenser panel.
2. Verify the following:
The boards and other components have not come loose from shipping. LCD display boards are not cracked
or damaged.
The cables are properly connected to the boards. There are no torn cables or stranded harnesses.
Pulser and pump handle harnesses are connected properly to the CPU board.
3. Make sure the shut off valves are closed. (If applicable)
4. Turn off all submerged pump circuit breakers and all other circuit breakers to the dispenser.
Make sure the 12-gauge green ground wire is properly connected and measures 1 ohm (or less) resistance
to earth ground. This measurement should be taken between neutral and ground at the dispenser. When
taking this measurement, make sure the ground and the neutral are disconnected at the dispenser. This
ensures that you are not taking your resistance reading across the electronics on the circuit board. If the
resistance reading is more than 1 ohm, the dispenser electronics may not operate properly and will void
the Bennett Limited Warranty.

Proceed to the section titled "How to Calibrate the DEF Meter".
HOW TO ELECTRONICALLY CALIBRATE A DEF METER (E-CAL)
The basic calibration procedure assumes that the test can sight glass is graduated in units of cubic inches or cubic
centimeters (milliliters). If the sight glass is in test can percentage units, refer to the optional calibration procedure
in the next section.
1. Under normal dispenser operation, fill a test can to verify proper meter calibration. If the meter is properly
calibrated, the procedure is finished.
2. If the meter is out of calibration, write down the amount of the error from the test can sight glass. The error
amount should be either cubic inches or cubic centimeters (milliliters).
3. Plug in the Manager Keypad to the J11 connector on the CPU/Control Board. Break the seal on the electronic

147193 Installation Manual DEF 100-200 Installation Introduction

calibration switch and move the switch to the calibrate position. This brings up the test can size display. This
switch is located on the top of the CPU board.
4. NOTE: If local preset exists, that keypad will be used.
5. With the Manager Keypad enter the size of the test can and press the ENTER button. The test can size ranges
from 0.1 to 999.9 volume units. When the test can size is entered, the error amount display appears.
6. Enter the amount of the error recorded previously and press the ENTER button. At this point, another test may
be filled for calibration verification by turning on the pump handle. If another test can is not desired, proceed to
step 7.
7. If another test can is filled, the error amount display appears as soon as the pump handle is turned off. If the
meter is out of calibration, write down the amount of the error from the test can sight glass. Repeat step 5.
8. Move the calibration switch back to the operate position and seal it. Disconnect the Manager Keypad.
The Optional Calibration Procedure
The optional calibration procedure assumes that the test can sight glass is graduated in test can percentage units rather than cubic inches
or cubic centimeters (milliliters) as in the basic calibration procedure. If the sight glass is in cubic inches or cubic centimeters, refer to the
basic calibration procedure in the previous section.
1. Under normal dispenser operation, fill a test can to verify proper meter calibration. If the meter is properly calibrated, the procedure
is finished.
2. If the meter is out of calibration, write down the amount of the error from the test can sight glass. The error amount should be a
percentage of the test can’s volume.
3. Plug in the Manager Keypad to the J11 connector on the CPU/Control Board. Break the seal on the electronic calibration switch and
move the switch to the calibrate position. This brings up the test can size display.
4. With the Manager Keypad enter the size of the test can and press the ENTER button. The test can size ranges from 0.1 to 999.9 volume
units. When the test can size is entered, the error amount display appears.
5. The default error amount display is for cubic inches or cubic centimeters. To bring up the percent error display, press the UP-ARROW
button.
6. Enter the amount of the error recorded previously and press the ENTER button. At this point, another test may be filled for calibration
verification by turning on the pump handle. If another test can is not desired, proceed to step 8.
7. If another test can is filled, the error amount display appears as soon as the pump handle is turned off. If the meter is out of calibration,
write down the amount of the error from the test can sight glass. Repeat step 6.
8. Move the calibration switch back to the operate position and seal it. Disconnect the Manager Keypad.
The Direct Percent Entry Procedure
The direct percent entry procedure provides a way of zeroing or overwriting the electronic calibration constant. This procedure is not
accumulative. The basic and the optional calibration procedures described previously are accumulative. The percent value entered in this
procedure becomes the new electronic calibration correction constant for the meter. This procedure requires no test can.
1. Break the seal on the electronic calibration switch and move the switch to the calibrate position. This brings up the test can size
display.
2. Press the UP-ARROW button to bring up the electronic calibration correction constant display.
3. Press the +/- button to bring up the percent error display.
4. Enter the percent error amount and press the ENTER button.
5. Move the calibration switch back to the operate position and seal it.
Viewing the Electronic Calibration Correction Constant
The electronic calibration correction constant may be viewed with the electronic calibration switch in either position (calibrate or operate).
If the switch is in the calibrate position, the correction constant can be viewed from the test can display by pressing the UP-ARROW button.
Pressing the UP-ARROW button a second time returns to the test can display. If the switch is in the operate position, enter manager’s
mode followed by menu 27 to view the calibration constant.
