Unloading, Unpacking, and Inspecting a New Dispenser

Bennett dispensers are bolted to a pallet and then carefully packaged with cardboard/styrofoam liners and a cardboard exterior carton. The entire package is then securely wrapped with plastic shrink wrap.

Use a fork lift to lift 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 that may have damaged the dispenser. If any damage is found, instruct the delivery driver to make a notation on the delivery receipt before signing it. If possible, open the carton and inspect the dispenser

before signing the delivery receipt. Bennett dispensers are shipped Ex-Works. 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

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 damage is found 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.

Once you are sure that there is no freight damage to the exterior of the dispenser, use the door key (wire tied to the nozzle hook) to unlock the lower door. Remove the lower door from both sides of 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

matches the order specified. Report any non-shipping related problems to Bennett Customer Service by mail, facsimile, telephone or

e-mail at the locations specified below: Bennett Pump Company

Lifting a New Dispenser and Placing it on the Island

The dispenser is bolted to a pallet with bolts and nuts. With the lower doors removed and safely stored away, remove the nuts and bolts that secure the dispenser to the pallet as shown in figure 1 and figure

2.

Figure 1 - Unlock the lower door with the keys

that come with the unit. Swing the door open 90

degrees and lift.

Figure 3 - Side View - Using lifting

straps to lift and move the dispenser. Notice the forks are spread wider than

the pump.

Thread two lifting straps (900 lbs. Capacity each minimum) through the dispenser as shown in figure 3 and figure 4. Be careful not to allow the straps to go under any of the hydraulic castings such as the meter outlet, copper tubes or valves. The straps should be lifting only against the front and rear chassis. Use a forklift or pallet lifting device with the forks spread wider than the pump and gently lift the dispenser. This lifting method will also work on the high hose dispenser. Place the dispenser gently on the island using care to line up the base anchor bolt holes with the anchor bolts embedded in the

concrete island.

WARNING: Lif t only to t he height required t o set the dispenser on th e island. Keep han ds

and feet clear of the dispenser while it is suspended in the air.

Figure 5 - Cover is screwed onto the top of the dispenser and must be removed to access the lifting brackets.

Figure 6 - After the top cover is removed, the lifting brackets can be accessed for lifting the dispenser from above.

Anchoring the Dispenser to the Island

The dispenser must be bolted firmly to the concrete island. The dispenser base is provided with anchor bolt holes (see base drawings in back of this manual for dimensions). Anchor bolts embedded in the concrete island must be not less than ½” diameter. The threaded ends of the anchor bolts should

project 1-1/2” above the concrete. On the Low Hose dispenser, 2 anchor bolts required minimum.

On the High Hose dispenser, 4 anchor bolts required minimum in the outer 4 mounting holes. Refer to the Footprint Drawings in the back of this manual for hole locations.

When anchoring the dispenser, always level the dispenser with shims before bolting to the island. Place the shims at the location of the anchor bolts so the dispenser frame is not distorted when the anchor

bolts are tightened down.

Determining the Number of Product Supply Pipes Needed

Step 1: Determi ne the type of suppl y line needed from t he model n umber’s 7t h position on the

serial tag. If the model number is 3711SNR (Note the R) the dispenser will require a submerged pump and pressurized supply line for each product. If the model number is 3711SNS (Note the S) the pump

will require a suction supply line for each product.

Step 2: Determine the nu m ber of p roduct pipes requ ired by finding the mo d el number below. Model Number Product Supply Lines Required

3711 / 3811 Use 1 product line plumbed to position 1. 3712 / 3812 Use 1 product line plumbed to position 1. 3722 / 3822 Use 1 product line plumbed to position 1 and 1 product line plumbed to position 2.

*Refer to base drawings in the back of this manual for product inlet locations. Pipe Size - The 3000 Series do not come with an inlet pipe or joint. The customer is responsible for the

1 1/2” NPT inlet pipe. These will thread directly into the inlet casting (see figure 7, figure 8 and figure 9).

Mechanical and Plumbing Notes

For remote dispensers, a U.L. Listed Emergency Shut Off Valve is required for each product inlet. The Emergency Shutoff Valve can be referred to as an “Impact Valve”, “Safety Valve”, “Shear Valve”, “Crash Valve”, or “Fire Valve”. The Emergency Shut Off Valve must be supported by the island frame or containment sump frame. Follow all instructions contained in the valve’s installation manual and

observe all national, state, NFPA, and local codes. For self-contained

(suction) pumps, a vertical check valve is required under each of the pump’s ground joint unions for the product inlet. The vertical check valve ensures that the pump’s hydraulic system remains full of product, and it is necessary to maintain the “prime” of the suction line so that liquid product does not drain back to the tank. Follow all instructions contained in the vertical check

valve’s installation manual and observe all local codes.

Product inlet locations and dimensions are on the footprint foundation

drawings in this manual.

Listed ground joint union must be installed between sheer section of Emergency Shut Off valve and dispenser inlet. If rigid product inlet pipes are used, they must be plumbed so no strain is exerted on the dispenser chassis caused by tightening

down the unions.

For dispensers used with companion satellites, follow all federal, state, and local codes regarding

installation of impact valves.

Install an approved emergency shut off valve, designed to close automatically in the event of severe impact or fire exposure, in the dispenser supply line at the base of the dispenser. The valve will also permit safe inspection and maintenance. Follow the installation instructions for the valve being

installed (see figure 10).

Pipelines and Underground Containment Sumps

General -

The dispenser must be mounted on a concrete foundation. Do not pour concrete around the product pipes or electrical conduit. The use of a UL approved containment sump designed for the Bennett Dispenser Model used is highly recommended. Follow the containment sump manufacture’s installation instructions for proper installation. If no containment sump is used, fill the sump area with clean sand or dirt as far up the product pipe as possible once installation is complete. Use water to pack the sand in

place (see figure 11 and figure 12) .

Figure 11 - Example of Remote Figure 12 - Example of Self Contained

NOTE: All piping must be clean of foreign debris, such as: oil, grease and shavings. All connections must be tight to prevent leaks.

Swing joints or flex pipe must be used at the ends of the horizontal pipe between the dispenser and the tank (see figure 13). These joints prevent leaks which might develop through ground movement from settling of the tank, frost heaving of the ground or pump island settling. The joint under the dispenser

also aids proper alignment of the product union or coupling.

NOTE: Please refer to PEI/RP100 Recommended Practices. The installation must conform to

EPA, NFPA, and State regulations for underground storage tanks.

Bennett self contained dispensers can be used with aboveground tank installations if the following

requirements are met:  An Underwriters (U.L.) Listed Pressure Regulating Valve designed for under-the-pump mounting is

installed for each pumping unit according to the valve manufacturer’s instructions.

 Any additional valves suggested by the Pressure Regulating Valve manufacturer are installed

according to the manufacturer’s recommendations.

 The installation must be installed and used in accordance with Federal, State, Local, and National

Electrical code NFPA #70 and Motor Fuel Dispensing Facilities and Repair Garages code NFPA

30A.

 Follow PEI/RP200 Recommended Practices for Installation of Aboveground Storage Systems.

Electrical Wiring Section -

For 3700 go to page 20 For 3800 go to page 38

Find the wiring diagram specific to the dispenser model for the dispenser that is being installed 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. Or, the dispenser may have been ordered with the optional explosion proof junction box located in the lower area of the dispenser. Using the door keys shipped with the dispenser, (on side 1) unlock the two locks on the upper electronics enclosure and open the door to access the wiring terminal on the CPU/ Control board. If there is a junction box then wire to the terminal strip and flying leads in the junction box. Refer to the instructions for wiring to the junction box under the “Wiring Diagrams”

section of this manual.

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 72” 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.

The wire separator (supplied with the pump) must be installed on the wires as they exit the conduit located in the electrical enclosure before the wires are terminated in the electronics enclosure. The wire

separator is needed to properly seal the conduit in the last step of installation.

Underground 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.

For Remote dispensers Bennett requires the installation of RC networks across the coil and contactors

of the sub-pump relays for proper operation of the dispenser. Failure to install the RC networks will void Bennett’s limited warranty.

Intercom wiring must be in a separate conduit from the dispenser conduit. DO NOT install intercom wiring in the same conduit as the dispenser wiring or else the Bennett Warranty will be voided and

improper system operation will result.

Dispenser Electronic Power must be on a separate dedicated circuit breaker. Do not put submerged

pump or self-contained 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. Follow all local, state and federal requirements for installation of vapor seals.

Electrical contractors must pull 72” 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.

Electrical Field Wiring

General Information

18

120001 Rev K 1-19-18

In instances where new dispensers are replacing old dispensers, Bennett recommends that new wiring

be pulled to each dispenser.

If existing wiring is used (not recommended) and does not reach to the dispenser electronic head (top area) of the dispenser, the wires can be extended only if the connections are soldered, weather proof

and contained in an explosion-proof type junction box. Follow all current national and local electrical codes for extending wire runs.

The maximum distance from the breaker panel to the dispenser is 500 feet. For self-contained units

increase the motor wire size from 14Ga to 12Ga for runs over 50 feet, increase the motor wire size from 12Ga to 10Ga for runs over 100 feet and increase the motor wire size from 10Ga to 8 Ga for runs over

250 feet. The power for the motors in 1 h.p. self-contained standard pumps must be located on the opposite

phase from the dispenser electronic power or be connected at 230V. This is necessary to limit the electronic noise from feeding back into the dispenser’s electronic power. Failure to observe this will create problems with the operation of the dispenser’s computers. Note: if 230v motor power is used be sure to set the motor switch located on the motor to the high voltage setting by moving the switch to the high position. Note: 2 h.p. Big Fueler motors do not have an adjustment switch. They must be wired for

230vac 1 phase, or 380vac 3 phase.

WARNING: DO NOT CROSS PHASE THE 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 its own electrical underground conduit. Wiring

from multiple dispensers in a single conduit is not allowed. All underground conduit should be rigid metal and drawn up tight. The use of PVC (plastic) conduit is not allowed and may void the Bennett Warranty. Make sure that vapor “seal offs” are properly installed on all conduits at and from each dispenser. Make sure any intercom wiring is not run with dispenser field wiring. A separate (second) conduit must be run

if using an intercom at the dispenser.

Purging Product Lines for Remote Dispensers

Once product piping and tanks have been tested for leaks and any leak conditions have been fixed then the remote dispenser product lines must be purged of all air that may be trapped in the lines. All

electrical connections must be made and verified at this time.

CAUTION! DO NOT USE THE DISPENSER TO PURGE AIR FROM THE PRODUCT LINES. RUNNING THE METER IN A DRY CONDITION AND AT THE HIGH SPEEDS RESULTING FROM

PRESSURIZED AIR, WILL DAMAGE THE METER AND VOID THE BENNETT LIMITED WARRANTY.

The emergency shutoff valve contains a test port that may be used to bleed off air that may be trapped in the product lines. Manually close the emergency shutoff valve. Do not leave this process unattended while purging the air from the product lines. Once liquid fuel product begins to weep from the test port, retighten the plug in the test port. If more than one dispenser is on a submerged pump product feed line, start this purging process at the dispenser furthest from the submerged pump and work backwards

toward the submerged pump.

WARNING! Take appropriate measures to contain any product seepage from the test port.

Dispose of any spilled product in proper manner consistent with applicable laws and codes.

Manually open the emergency shutoff valve and lock it into the “on” position according to the instructions from the valve manufacturer. Use a test prover can or other appropriate approved container to dispense 50 to 100 gallons or 175 to 350 liters 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 an over-speed pulser error.

Once the dispenser has dispensed 50 gallons of fuel, the SB100 meter should be tested for calibration.

Refer to the section in this manual for calibration procedures.

Purging Product Lines for Self Contained Systems

Once product piping and tanks have been tested for leaks and any leak conditions have been fixed then the self contained (suction) dispenser product lines must be purged of all air that may be trapped in the

lines. All electrical connections must be made and verified at this time.

The pumping unit evacuates all the air in the pipe before it gets to the meter. The air is expelled through the vent at the top of the pumping unit. Nothing but fuel should pass through the meter. The meter will

not turn until fuel enters the pump and pressurizes the system.

WARNING! Take appropriate measures to contain any product seepage from the air elimination chamber tube. Dispose of any spilled product in proper manner consistent with applicable laws

and codes.

Use a test prover can or other appropriate approved container to dispense 50 gallons or 175 liters through the dispenser. Begin dispensing by only slightly opening the nozzle to allow any entrapped air

in the dispenser to slowly release through the air eliminator. This prevents over-speeding of the meter.

Once the dispenser has dispensed 150 gallons of fuel, the SB100 meter should be tested for calibration.

Refer to the section in this manual for calibration procedures.

120001 Rev K 1-19-18

Piping Notes for Self-Contained Systems

To obtain maximum flow rates on a self-contained pump, follow these guidelines (see figure 14): The total length of horizontal piping between the pump and tank must be no longer than 60 feet. Use new 1-1/2” galvanized or approved non-metallic pipe for 10-15gpm pumps. Use new 2” galvanized

or approved non-metallic pipe for 20-24 gpm pumps.

All horizontal piping must be buried a MINIMUM of 18” below the finished grade to minimize temperature

effects. The pipe from the tank must slope up to the pump (approximately 1-1/2” to 2” per 10 feet). The piping

run should not have any high or low spots (hills or valleys). The pipe must be supported continuously to

prevent sagging. All piping must hold a 50 PSI pressure test for 10 minutes.

To absorb ground movement from settling of the tank, frost heaving of the ground or pump island settling, a swing joint or flex pipe must be used in the supply line at the tank and directly underneath the

dispenser.

Only one pumping unit is permitted for each underground pipe. Two pumps on one suction line is not

recommended. Static lift on self-contained units must not exceed 10 feet (vertical distance between product level in the

storage tank and the center of the pumping unit). All Installation work must conform to federal, state, and local codes. Above Ground Tanks - If using above ground tanks, make sure a vacuum actuated pressure regulating

valve is properly installed.

Follow Petroleum Equipment Institute’s Recommended Practices for Installation of Underground Liquid

Storage Systems RP100 and/or Recommended Practices for Installation of Above Ground Storage Systems for Motor Vehicle Fueling RP200. The installation must conform to EPA, NFPA, and State

regulations for storage tanks.

Copies of PEI’s recommended practices can be order through their web site at: www.pei.org

NOTE: Please refer to PEI/RP100 Recommended Practices. The installation must conform to

EPA, NFPA, and State regulations for underground storage tanks.

See General Wiring Requirements on pages 16, 17

22

120001 Rev K 1-19-18

The 531 commercial electronics package in the model 3700 unit is a very simple design. There will be one “control” (CPU) board per hose. The dispenser may be ordered as a one or two hose unit. One hose units have one control board, and two hose units have two control boards. The control board is where the field wires will connect if the optional junction box is not ordered. The Installer will run power wires to side 1 product “A” CPU/Control board. Side 1 will be the side with the serial tag located inside the electronics enclosure on the deck to the right. If the dispenser is a dual product, Product A CPU will be on side 1 to the right. If there are more than 1 CPU/Control Boards, the boards are factory wired from board to board for power. Please refer to the Remote Power Wiring Diagram located in the Wiring

Diagram section of this manual:

Determine the wires needed in each step and add the number of wires from each step together to

determine total number of wires required.

Step 1. Dispenser Power - Every model of 3700 requires these wires: (1) 12ga. Green ground wire (1) 14ga Black L1 power wire for electronics power. (1) 14ga. White for 115V neutral or red for 230V L2, for electronics power.

Step 2. Console Communications -If the dispenser is to be connected to a control console, remote

communication wires will be needed. The 3700 model dispenser uses RS485 communication to the

control console.

To side 1 Product “A” (CPU Board): (1) 18ga. wire for RS485 communication positive. (Orange) (1) 18ga. wire for RS485 communication negative. (Brown) (1) 18ga. wire for RS485 communication common. (Black)

Note - Use twisted wires for the communication wiring at 3 twists per foot. If there is more than one

CPU/Control Board, the RS485 data wires are wired at the factory from board to board. The Installer does not have to pull 3 separate RS485 wires for each control board in the same dispenser. Please refer

to the RS485 Communication Wiring Diagram located in the Wiring Section of this manual. Note - Belden twisted shielded cable is accepted as long as the drain is only terminated on one end.

Terminate the drain to the ground lug in the interface box within the building. Step 3. Remote Dispensers (Submerged Pump) -a remote relay control wire will be required for

each plumbed product. If there is only one product, only one submerged pump control wire is needed. If there is a second product, a second submerged pump control wire will be needed. Please refer to the

Remote Power Wiring Diagram located in the wiring section of this manual.

For Product “A” Hose Position (Control Board): (1) Blu e 14ga. wire. For Product “B” Hose Position (Control Board): (1) Bro w n 14ga. wire.

Step 4. Self-Contained (Suction Pump)- a separat e ci rcuit and cir cuit breaker w ill be requi red for

each pumping unit motor. Place the pumping unit motor power circuit breakers on the opposite phase from the dispenser’s electronic power or on 230VAC. This will keep the dispenser’s electronic power free from electronic noise. The dispenser may have one motor (single product) or two motors (dual product). Each motor requires two field wires. Please refer to the Self Contained Power Wiring Diagram

located in the wiring section of this manual.

Needed for each Pumping Un it Motor : (1) Red for L2 14 ga.* Hot & (1) White 14 ga. Neutral on 115V circuits

* Note: “L2” refers to a different phase leg from dispenser power. Runs longer than 50ft. will require larger wires. Size wires to minimize voltage loss or run the motors on 230V circuits to minimize the

current in the wires.

(1) Red for L2 14 ga.* Hot & (1) Black 14 ga. for L1 Hot for 230V circuits.

OR

23

120001 Rev K 1-19-18

Step 5. Mechanical Pulse Output - If the dispenser is to be wired to a mechanical interface card/key system, the following wires will be needed:

(2) Pulse output wires per CPU/Control Board (+) and (-) 18 ga. * (2) Pulse output wires per CPU/Control Board for tank gauge interface (+) and (-) 18 ga. * (If applicable) (2) Handle circuit wires per CPU/Control Board (+) and (-) 18 ga. * (1) Authorization wires per CPU/Control Board (+) and (-) 18 ga. *

Note - The field wiring will be connected between a Bennett Pulse Output Board and the third party

interface system. This board will be mounted on the deck inside the electronics enclosure. One Pulse Output Board can handle two CPU/Control Boards per Product. There can be a maximum of two Bennett Pulse Output boards per dispenser. Please refer to the Pulse Output Wiring Diagram located in

the Wiring Section of this manual. IMPORTANT NOTE - When the dispenser is ordered as a “Dual” AND the Pulse Output will tie to a

Tank Gauge System, the Installer will be required to pull many wires to the dispenser. In this case, the dispenser should be ordered with a second “optional” field wire conduit and a second conduit for field

wires should be run to the dispenser. *Note - The Installer should follow the recommended color coding for field wires found in the Pulse

Output Wiring Diagram section of this manual. Note - The installer will not need RS-485 wires if the Mechanical Pulse Output option is chosen. Step 6. Intercom Systems - if the dispenser is ordered with an intercom (speaker and call button) the

Installer must pull wires for it. The following wires are required:

(2) Speaker wires 18 ga. (2) Call Button (optional) 18 ga.

Note - Run these wires in separate conduit. Do NOT run with dispenser electronic wires. WARNING - DO NOT PULL INTERCOM WIRING WITH DISPENSER WIRING IN THE SAME

CONDUIT! INTERCOM WIRING AND DISPENSER WIRING SHOULD BE RUN IN SEPARATE CONDUITS TO THE DISPENSER. INTERCOM SYSTEM MALFUNCTION WILL OCCUR IF THESE

WIRES SHARE THE SAME CONDUIT. Refer to the Wiring Diagram section of this manual for Intercom Wiring.

120001 Rev K 1-19-18

Pulling the Field Wires

Open the lower door on the dispenser on side 1 and locate the inlet wiring electrical conduit. The conduit is located on side 1 in the center. This conduit is where all of the field wires will be pulled into the Electronics enclosure. Side 1 of the dispenser is the side with the serial plate on the inside deck. If this dispenser was ordered with a junction box, open the explosion proof junction box. The junction box is located on side 1 in the lower (hydraulics) area. Otherwise, open the upper electronics enclosure door on side 1 and locate the field wiring conduit. Pull the dispenser wires through the underground conduit and into the upper electronic enclosure. Make sure that the copper ends of the wires are clean and free

of oxidation.

Installing the Wire Separator

Underwriters Laboratory, the local Fire Marshall and a safe installation requires that a wire separator be installed on the wires as they are routed through the conduit and into the dispenser’s electronic enclosure. The wire separator holds the wires apart to ensure that the seal off compound fully seals around each wire. Apply the seal off compound during the last step of the installation. This will prevent gasoline fumes from working their way into the electronic enclosure. The wire separator is supplied in the plastic bag located inside the dispenser electronic enclosure. Run each field wire through a hole in the wire separator and then push the wire separator into the conduit at least 3/4”. Make sure the “Chico” type fiber material has already been pushed into the conduit, around the wires as

shown in figure 15.

Figure 15 - Wire Separator

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.

25

120001 Rev K 1-19-18

AC Power Installation

Each dispenser uses one 115V, 50/60 Hz 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. Only one dispenser electronics Hot and Neutral needs to be pulled per dispenser. That power will be jumped from Control Board to Control Board in the electronics head (at the factory) if

there is more than one Control Board in the dispenser.

All references to 115VAC in this manual can also be identified as 230VAC if the dispenser ordered is for 230 VAC. Note: 115VAC installations: L1 is hot and L2 is Neutral. In 230VAC installations: L1 is hot

and L2 is the other phase hot. Electronic Power Connections:

1. Connect the White (Neutral) 14ga. wire in 115V circuits or the Red 14ga. wire in 230V circuits to terminal 1 of TS2 on the CPU board. The CPU board is located on the upper electronics door.

2. Connect the Black (Hot) 14ga. wire to terminal 2 of TS2 on the CPU board.

3. Electronic 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 phas-

ing will result in the remote sub-pump relay control circuits.

Rules to ensure proper operation:

1. Each dispenser uses one 115V, 50/60 Hz or 230V, 50/60 Hz circuit for dispenser power. Put no more than two (2) dispensers on a circuit breaker (for Electronic Power).

2. Do not connect any other devices or motors to these circuits.

3. Put the pump wiring in its own 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 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

Connecting the Sub Pump Control Wiring 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. Red Jacket and F.E. Petro are two of the most common manufactur-

ers of submerged pumps. Check with those manufacturers for more information on control relay boxes.

Connect the “Motor Out” power wires between the dispenser and the control relay box for each product

as follows: Submerged Pump Motor Control - Connect to terminal 3 of TS2 on the CPU/Control board on side 1

of the dispenser. This should be a 14 ga. wire. If there is another CPU/Control board for this SAME PRODUCT, install a jumper wire between terminal 3 of TS2 of both boards. This allows terminal 3 of both boards to control the same submerged pump relay for that product. This should be a 14 ga. wire also. It is recommended that for Product “A” the Installer use a Blue wire for submerged pump motor control and if there is a second product (Product “B”) use a Brown wire for submerged pump motor con-

trol. 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 P2 on the CPU if controlling a submerged pump relay. This

will be set at the factory.

An RC Network is an electrical noise suppression device (see figure 16 and figure 17). It is used on AC power devices such as coils and across relay contacts. When AC voltage is applied to coils they are converted to electromagnets. Coils are used to operate AC devices, such as solenoid dispensing valves and AC power relays or contactors. W hen the AC power is removed from a coil, the electromagnetic field collapses. This causes an AC voltage spike as high as 1500 VAC which can affect electronic

systems.

Install the three RC Networks in the Control Relay Box across the following (Refer to the Remote Power

Wiring Diagram in the Wiring Section of this manual):

Figure 16 - An RC Network.

Check local code requirements concerning complete disconnect of submerged pump voltages. RC

Networks will allow voltage to be present at all times.

Connecting Pump Motor Power for Suction Pump Systems

Connecting Pump Motor Power for Self-Contained Pumps

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. Use 14-gauge stranded THHN wire minimum for the suction pump motor wires for runs

under 50ft. 12Ga. for runs to 100ft, 10ga.for runs over 100ft, and 8 ga. for runs over 200 feet. Pump

motor power must be on a different phase leg than the dispenser power or system malfunction

will result and the Bennett Limited Warranty will be voided.

Termination of Field Wiring for Pump Motor Power of Self-Contained Dispensers

Note: Wire termination for 3-phase Motor Connections for 3000 series self-contained pumps with 210

or 531 electronics will be terminated directly to a 3-phase contactor relay or terminated to a contactor board as shown in Figure 18.

Mechanical Mode - Mechanical Mode allows the 3000 series to imitate a mechanical dispenser and interface to a Fleet System. It also allows pulse output communication with a Tank Gauge.

A separate Mechanical Pulse Output Interface Board is required for the dispenser. There will be one Pulse Output board for a single product (single hose or twin) dispenser . The board can output two channels (Side 1 and Side 2) of pulse information for a console and also for a tank gauge, handle switch output for pump “in use” signal, and an input for an “authorization” signal for each side of the dispenser for a product. The mechanical interface board is mounted on the deck inside the electronics enclosure.

This mechanical interface board also communicates with the CPU boards. Pulse Output - The pulse output allow s the 3000 mechani cal i nterface to send pulse inf ormation

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 and the table on the next page to see how to wire to the Pulse Output Board. The drawing shows how to wire directly to the pulse output board OR, if there is an optional junction box installed, the correct wiring to the junction box. Also, the

table lists correct wiring to the Pulse Output Board OR to the optional junction box.

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 and the table on the next page 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 and the table on the next page 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 and the table on the next page to see how to wire the

Tank Gauge signals.

Setting the Jumpers on the Pulse Output Board

The Pulse Output board is ordered as an option with the Electronic 3000 series. This board is where the field wires connect the 3rd party Fleet System to the Pulse Output functions of the dispenser. This board also has jumpers that need to be set to determine the Pulse Rate and the Pulse Width. Whatever pulse rate is set will send the same pulse rate and width to both the Fleet System and the Tank Gauge

(if one is connected). This section describes how to set these jumpers. Refer to the Figures below:

JP1-1,2,3,4,and 5 are used to set the pulse rate and pulse width.

JP2 is currently not used.

Figure 20 - Pulse Output Board Jumpers

Figure 19 - Pulse Output Board

This is the Pulse Output Board. It has the terminal strips for the field wire connections along the bottom of the board to communicate with the Fleet System using a pump handle output signal, an authorize input signal and a pulse train signal. The Jumper Header JP1 is at the top left of the board. These jumpers must be set to determine the pulse rate and

the pulse width. See information below.

To set the Pulse Rate Output, set jumpers JP1-1 and JP1-2 as follows: JP1-1 JP1-2 Pulses Per Gallon Pulses per Liter

OUT OUT 1000 100 IN OUT 100 10 OUT IN 10 1 IN IN 1 1/10TH

To set Pulse Width, set jumpers JP1-3, JP1-4, JP1-5 as follows (PULSE WIDTH’S ARE IN MILLISECONDS):

JP1-3 JP1-4 JP1-5 Pulse Width Pulses Per Minute OUT OUT OUT .5 ms 60000 IN OUT OUT 1 ms 30000 OUT IN OUT 2 ms 15000 IN IN OUT 4 ms 7500 OUT OUT IN 8 ms 3750 IN OUT IN 16 ms 1875 OUT IN IN 32 ms 9378 IN IN IN 64 ms 467

The top left of the Pulse Output board has a jumper header called JP1. It has 8 jumper positions. Set the Pulse Rate with the first two jumpers and the Pulse Width with the 3rd, 4th

and 5th. See information below.

CPU Board Jumper Configuration

The 3700 Series can operate in two different modes, Console or Stand Alone, which must also be

defined by jumper settings on the CPU board: Stand Alone Mode -Stand Alone mode allows the 3700 Series to operate without being connected to a

console or control device. In this mode, when the handle is turned “on” the dispenser authorizes itself. Console Mode - Console mode allows the 3700 Series to communicate with compatible consoles or

control devices using a RS485 communication data loop. Also, the dispenser is also set for Console

mode when operating in mechanical mode with a Pulse Output board to a Fleet System. See below. Mechanical Mode - Mechanical mode allows the 3700 Series to imitate a mechanical pump and

interface to a Fleet System. There is no actual “mechanical mode” to select. For this type of interface, a separate “pulse output” board must be ordered with the system and the Console mode must be selected. So, to put the system into “Mechanical Mode” install a Pulse Output Board and select the Console Mode w ith the jump er. The field wires between the Fleet System and the dispen ser would be connected to the Pulse Output Board. This board would be used to output pulse data, handle switch status information and would receive authorization signals from the Fleet System. When setting

the system up to imitate a mechanical dispenser, select CONSOLE mode. See the following section.

The 3700 series dispensers are programmed using “jumpers” or “shunts”. The jumper header JP1 is a 9 position header and is located on the top right corner on the back of the CPU/Board. This jumper header is used to program the dispenser (see f igure 21). Jumper configur at ion chang es may be required on the CPU circuit board at the site. See the chart below for a quick reference of what the jumpers do. See the next page for an explanation of each jumper setting.

Jumper Header JP1 is located on the top right of the back of the CPU / Control board. This board is mounted to the upper door. It has 9 positions. Jumpers should be set with dispenser power off. The jumper settings are

only read on “power up”.

The 3700 Series is shipped from the factory configured for the console mode of operation. In the “Console” mode, the 3700 electronic commercial dispenser can communicate with any console that can communicate using RS485 communication. It is also set for Console when using the mechanical interface pulse output board. When in the “Console” mode, after the handle is lifted, the dispenser must receive the “authorization” command from the console or controlling device before the dispenser resets

and begins the sale.

Jumper Header JP1 is a 9 position jumper header (see figure 22). Position 5 is for setting the dispenser in the Console or Stand Alone mode. Placing the jumper across the pins on position 5 puts the

dispenser in Console mode. This jumper configures the CPU for RS485 output on TS1 (Field wire connection to the Console). TS1-7 = DATA (–)

TS1- 6 = DATA (Common) TS1 - 5 = Data (+)

CPU Board Jumper Configuration

Stand Alone Mode - Setting Jumpers

In the Stand Alone mode, the dispenser does not require an outside “authorization” signal from any console or control unit. When the handle is lifted, the dispenser “authorizes” itself and the dispenser

resets and the sale begins.

Jumper Header JP1 is a 9 pin jumper header. Position 5 is for putting the dispenser in the “Stand Alone” or “Console” mode. Removing the jumper from JP1 position 5 puts the dispenser in the Stand

Alone mode. Setting the Jumpers— The jumpers should be set with power off and are only “read” at boot-up (power

up). WARNING - DO NOT SET OR REMOVE JUMPERS WITH DISPENSER POWER TURNED ON!

DAMAGE TO THE DISPENSER MAY RESULT. ALWAYS MAKE SURE DISPENSER POWER IS OFF

AND THE BACK-UP BATTERY IS BYPASSED WHEN ADDING OR REMOVING JUMPERS!

The 9 position Jumper Header is located on the CPU board. It is used to set the hose position address

and to program the dispenser. Jumper Positions 1 - 4 - (Fueling Point Address - Up to 16 fueling position addresses). Use jumper

positions 1 through 4 to set the dispenser address. Normally, Bennett pumps do not need an address set when using current loop communications but with RS 485 style communication an address must be set for the 3rd party device or console to know which fueling point it is talking to. The first four rows of

pins (on jumper header JP1) represent a binary number whose greatest value is 16 (or 0-15). The

fueling point address must be set to identify each hose position / fueling point using these jumpers. See the chart on the next page for details on how to set the address for a specific fueling point number using

the jumpers on the first four rows of jumper header JP-1. Jumper Position 5 - Console or Stand Alone -

In - Console (or Mechanical) Out - Stand Alone

Jumper Position 6 - Motor delay (suction pumps without valves). This function allows a 2 second delay

preventing the dispenser from turning on immediately when the pump handle is lifted. This would be used on a dispenser with self contained pumps and no valves. Set the dispenser for the two second delay so that the motor does not come on immediately when the handle is thrown allowing the dispenser

to pump through a hose without a valve before the dispenser resets. In - 2 second delay Out - No Delay

Jumper Position 7 - Leak Detector Pre-charge - This function allows the system to energize the

submerged pump pressurizing the line to check for leaks before the valve opens. The jumper should be

out in most cases unless the leak detectors routinely trip (very slow flow from the nozzle - then use 9 seconds). In - 9 seconds Out - 2 seconds

Dispenser Startup and Checklist

DANGER: Fire, explosion, injury or death will occur if fuel vapors are present. Make sure there

are no vapors present before starting this procedure. 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 and lower dispenser doors.

2. Check to make sure:

 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.

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 the resistance read is not 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.

Turn on 115 or 230 Volts AC dispenser power to the unit.

1. Use a voltmeter to verify 115 or 230 Volts AC only at Terminal 2 on TS2 of the CPU board. Terminal 1 of TS2 on the CPU board is Neutral. This AC circuit provides power to the electronic boards.

2. Make sure displays are normal and not garbled.

WARNING: Make sure all dispenser power circuits for REMOTES ONLY are on the same phase/

leg of the breaker panel or damage will result.

3. Turn the dispenser power off. Program the dispenser for Stand Alone operation by removing the

jumper from JP1 jumper 5 . (Do not lose this jumper because it may be needed again later). Refer

to the previous section for jumper settings. Turn the dispenser power back on.

CHECK THE PUMP MOTOR CIRCUIT

Remotes

WARNING: To prevent injury, make sure impact valves and submerged pump breakers are off.

1. Put the 1st Product’s pump handle in the ON position. The dispenser display will reset. Use a voltmeter to verify 115 or 230 Volts AC on Terminal 3 on TS2. Use Terminal 1 as neutral.

2. Put the 1st Product pump handle in the OFF position.

3. Repeat this process for the remaining hose positions.

4. Turn on all handles for the same product and make sure the dispensers are operating properly.

Make sure all dispensers for each product are on the same phase of power. The dispensers should

not be on different phases of power.

5. Open and set the impact valves.

Dispenser Startup and Checklist

Self-Contained

WARNING: If the lower door on the pulley side of the unit is off, close the door and lock it to

prevent injury.

1. Verify that the motor voltage select switch on the self contained motor is in the proper position. (if applicable)

2. Turn on the 1st Product pump motor circuit breaker. With the pump handle OFF, use a voltmeter to

verify 115/230 Volts AC power for the self contained pump motor by measuring between (Hot) terminal 4 on TS2 of the CPU and (Neutral) terminal 1 of TS2 of the CPU board. Also, if this is a 230 volt A.C. power circuit for the suction pump motor, check between terminal 4 of TS2 on the CPU board and neutral of the pump motor. The pump motor has two wires coming into the dispenser head from the motor. One lead connects to the dispenser electronics (factory connected) and the other lead is for the installer to run the neutral return. If the motor is being operated off of 230 volts, this is the other phase leg for the suction pump motor. The solid state relay for the suction pump

motor is located on the CPU board. The 1st Product pump motor should not be running at this time.

3. Turn off the 1st Product pump motor circuit breaker.

4. Repeat this test for the remaining hose positions.

All Dispensers

1. Turn off all circuit breakers.

2. Close and lock the lower doors and the upper doors.

3. Turn the circuit breaker for the system on.

4. Purge the air from the system.

How to Mechanically Calibrate the SB-100 Meter

(M-Cal Option)

The Bennett SB-100 Meter is built to maintain accurate measurement under normal operating

conditions. The meter is a positive displacement device with rods and pistons, which require a break in period. The meter is calibrated at the factory using a solvent for safety purposes and must be calibrated

after it has been installed. We strongly suggest recalibration of the meter after a 90 day break in period.

With the 3700 series electronic dispenser, mechanical calibration is optional. The standard 3700 is calibrated electronically. This means that the meter in the dispenser may not be able to be calibrated mechanically (it will not have a mechanical calibration wheel). If the meter on the dispenser does not have the mechanical calibration wheel on it then it will be required to use the electronic calibration

option. Go to the next section in this manual that explains how to perform an electronic calibration. The dial adjusting cover has (+) and (-) arrows to

indicate the correct direction to rotate the dial to

either increase or decrease delivery.

The dial cover has two pin hubs, one to the left of the shaft and one to the right. The seal pin may be inserted in either hub (see figure 27). The smallest adjustment (.6 cu. in.) occurs when the pin is pulled from one side and inserted in the other side by moving the dial the least amount or half a hole. A

1.2 cu. in. adjustment is made by pulling the pin

and turning the dial until the next adjacent hole

aligns with the same hub and reinserting the pin.

To calibrate the meter, follow this procedure:

1. Measure the actual delivery of the meter at fast

flow in an accurate test measure. Dispense a

minimum of 5 gallons (20 liters).

2. Cut and remove the existing seal wires and remove the seal pin (see figure 27).

3. Turn the dial the necessary amount in the (+) or (-) direction to increase or decrease the quantity of fuel delivered.

4. Re-insert the seal pin in the desired pin hub.

5. Dispense 5 gallons (20 liters) of fuel to allow

the meter to adjust to the new settings. Do not

make any adjustments based on this delivery.

Electronic calibration is a simple method to calibrate the meters in the dispenser. This method uses a mathematical algorithm in the software to account for meter wear rather than mechanical methods to limit the piston

throw within the meter.

This method also eliminates the parts associated with mechanical calibration in the meter. The result is a more symmetrical meter that will be

intrinsically more accurate. Follow these steps to electronically calibrate the meter: Step 1 - Pump 5 gallons, as displayed on the dispenser display, into the test

can. Make sure to stop pumping at exactly 5.000 gallons.

Step 2 - Read the plus / minus value in the test can. Step 3 - Unlock and open the electronics door on the side with the meter

that is being calibrated (see figure 28). IMPORTANT - Make sure to

calibrate the correct meter! To make sure, locate the meter that is being worked on and the valve that is connected to it. Follow those valve wires to the correct CPU/Control Board to ensure that the correct meter is being electronically calibrated (see figure 29). With the power on, locate the electronic calibration switch on the top of the CPU/Display board, which is

mounted to the door (see figure 30). Step 4 - Break the seal and move the switch to the calibrate position. Close

the door. The display should read the current calibration value. Step 5 - Press the “Enter” button along the top edge of the CPU/Display

board. Figure 31 shows that there are 3 buttons next to the electronic calibration switch. The functions of the buttons are “Enter”, “Up”, and

“Down”. Use these buttons to enter electronic calibration data.

Step 6 - The display should say “tc 000.0” (see figure 32). Enter the Test

Can size that is used for this procedure. Do this by using the “Up” key on the top of the board. (Typically 5 gallons or 20 liters). Press the “Enter”

button.

Step 7 – Enter the value of the measurement dispensed in the test can, this will be a positive or negative amount (above or below the “0” mark). If the test can measurement was “above” by 2 cubic inches, press the “Up” button

twice. If the measurement in the test can was “below” , for example, -1 cubic inch, change the sign to (-) minus by pressing the “down” button so

that the display shows “in –01.0” (see figure 33) . Press the “Enter” button

for the system to accept the information. Step 8 - The system displays a message that shows “Cal On” with the

current calibration parameter (see figure 34).

Step 9 - Turn the ecal switch to the “Off” position and reseal (see figure 35).

Wiring the 3800 Series

Dispenser

Retail

See General Wiring Requirements on pages 16, 17

120001 Rev K 1-19-18

The 210 retail electronics package in the model 3800 unit is a very simple design. There will be one “control” (CPU) board per hose. The dispenser may be ordered as a one or two hose unit. One hose units will have one control board, two hose units will have two control boards. The control board is where the field wires will connect if the optional junction box is not ordered. The installer will only have to run dispenser power to side 1 product “A” CPU/Control Board. If there is more than one CPU/Control board, the boards are factory wired for power from board to board. That is, power from board to board is wired at the factory. Please refer to the Remote Power Wiring Section of this manual. Each control board will

be wired as follows:

Determine the wires needed in each step and add the number of wires from each step together to

determine total number of wires required.

Step 1. Dispenser Power - Every model of 3800 requires these wires: (1) 12ga. Green ground wire (1) 14ga Black L1 power wire for electronics power. (1) 14ga. White for 115V neutral or red for 230V L2, for electronics power.

Step 2. Communications Wiring - For communications, the 210 electronics can communicate using 2 wire current loop or 3 wire RS-485. If the dispenser is to be connected to a control console using the

Current Loop protocol, rem ote communi cation w i res will be needed . Run 2 separate wires f or each current loop channel. Refer to the Current Loop Communication Wiring Section of this manual

and follow these guidelines:

Current Loop - For each Hose Position (CPU): (1) 18ga. wire for communication positive (+) (1) 18ga. wire for communications negative (-) *Note - Follow the recommended color coding found in the wiring diagram.

RS - 485 Protocol - When using RS - 485 communication, 3 communication wires will be needed for

each dispenser. Even if there is more than one CPU/Control Board, only 3 wires are needed for the

entire dispenser. Refer to the RS-485 Communication Wiring Diagram. To side 1 Product “A” only (CPU): (1) 18ga. wire for RS485 communication positive. (Orange)

(1) 18ga. wire for RS485 communication negative. (Brown) (1) 18ga. wire for RS485 communication common. (Black)

Step 3. Remote Dispensers (Submerged Pump) - A remote relay control wire will be required for

each plumbed product. If there is only one product, only one control wire is needed. If there are two products then two control wires are needed. Please refer to the Remote Power Wiring Diagram in the

wiring section of this manual.

For Product “A” : (1) Blue 14ga. w i re. For Product “B” : (1) Brown 14ga. w ire

Step 4. For Self-Contained (Suction Pump) - A separate circuit and circuit breaker will be required for

each pumping unit motor. Place the pumping unit motor power circuit breakers on the opposite phase from the dispenser’s electronic power or on 230VAC. This will keep the dispenser’s electronic power free from electronic noise. The dispenser may have one motor (single product) or two motors (dual product). Each motor requires two field wires. Please refer to the Self Contained Power Wiring diagram

located in the wiring section of this manual. Needed for each Pumping Un it Motor :

Note: Runs longer than 50ft. will require larger wires. Size wires to minimize voltage loss or run the

motors on 230V circuits to minimize the current in the wires.

Determining the Number of Wires Needed

(115 or 230 Volt Installations)

(1) Red for L2 Hot & (1) White 14ga. Neutral on 115V circuits

(1) Red for L2 Hot & (1) Black for L1 Hot for 230V circuits.

120001 Rev K 1-19-18

Step 5. Mechanical Pulse Output - If the dispenser is to be wired to a mechanical interface card/key system, the following wires will be needed:

(2) Pulse output wires per CPU/Control Board (+) and (-) 18 ga. * (2) Pulse output wires per CPU/Control Board for tank gauge interface (+) and (-) 18 ga. * (If applicable) (2) Handle circuit wires per CPU/Control Board (+) and (-) 18 ga. * (1) Authorization wires per CPU/Control Board (+) and (-) 18 ga. *

Note - The field wiring will be connected between a Bennett Pulse Output Board and the third party

interface system. This board will be mounted on the deck inside the electronics enclosure. One Pulse Output Board can handle two CPU/Control Boards per Product. There can be a maximum of two Bennett Pulse Output boards per dispenser. Please refer to the Pulse Output Wiring Diagram located in

the Wiring Section of this manual. IMPORTANT NOTE - Wh en t he d ispenser is ordered as a “ Dual” AND t he Pulse Ou tput will tie to

a Tank Gauge System, the Installer will be required to pull many wires to the dispenser. In this case, the dispenser should be ordered with a second “optional” field wire conduit and a second conduit for field

wires should be run to the dispenser. *Note - The Installer should follow the recommended color coding for field wires found in the Pulse

Output Wiring Diagram section of this manual. Note - When the system has the Mechanical Pulse Output Option the installer will not need to run current loop or RS485 communication wiring.

Step 6. Intercom Systems - If the dispenser is ordered with an intercom (speaker and call button) the Installer must pull wires for it.

The following wires are required:

(2) Speaker wires 18 ga. (2) Call Button (optional) 18 ga. * Run these wires in separate conduit. Do NOT run with dispenser electronic wires.

WARNING - DO NOT PULL INTERCOM WIRING WITH DISPENSER WIRING IN THE SAME

CONDUIT! INTERCOM WIRING AND DISPENSER WIRING SHOULD BE RUN IN SEPARATE CONDUITS TO THE DISPENSER. INTERCOM SYSTEM MALFUNCTION WILL OCCUR IF THESE

WIRES SHARE THE SAME CONDUIT. Refer to the Wiring Diagram section of this manual for Intercom Wiring.

120001 Rev K 1-19-18

Pulling the Field Wires

Open the lower door on the dispenser on side 1 and locate the inlet wiring electrical conduit. The conduit is located on side 1 in the center. This conduit is where all of the field wires will be pulled into the Electronics enclosure. Side 1 of the dispenser is the side with the serial plate on the inside deck. If this dispenser was ordered with a junction box, open the explosion proof junction box. The junction box is located on side 1 in the lower (hydraulics) area. Otherwise, open the upper electronics enclosure door on side 1 and locate the field wiring conduit. Pull the dispenser wires through the underground conduit and into the upper electronic enclosure. Make sure that the copper ends of the wires are clean and free

of oxidation.

Installing the Wire Separator

Underwriters Laboratory, the local Fire Marshall and a safe installation requires that a wire separator be installed on the wires as they are routed through the conduit and into the dispenser’s electronic enclosure. The wire separator holds the wires apart to ensure that the seal off compound fully seals around each wire. Apply the seal off compound during the last step of installation. This will prevent gasoline fumes from working their way into the electronic enclosure. The wire separator is supplied in the plastic bag located inside the dispenser electronic enclosure. Run each field wire through a hole in the wire separator and then push the wire separator into the conduit at least 3/4”. Make sure the “Chico” type fiber material has already been pushed into the conduit, around the wires as

shown in figure 36.

Figure 36 - Wire Separator

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 screw on the electronics enclosure deck.

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 conduit as a ground.

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 remote dispenser uses one 115V, 50/60 Hz 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 power / CPU board. Only one dispenser electronics Hot and Neutral needs to be pulled per dispenser. That power will be connected from Control Board to Control Board in the electronics head (at the factory) if there is more than one Control Board in the dispenser. Refer to the

Remote Power Wiring Diagram in the Wiring Section of this manual.

All references to 115VAC in this manual can also be identified as 230VAC if the dispenser ordered is for 230 VAC. Note: 115VAC installations: L1 is hot and L2 is Neutral. In 230VAC installations: L1 is hot

and L2 is the other phase hot.

Electronic Power Connections:

1. Connect the White (Neutral) 14ga. wire in 115V circuits or the Red 14ga. wire in 230V circuits to TS2 Terminal 1 on the CPU Board.

2. Connect the Black (Hot) 14ga. wire to TS2 Terminal 2 on the CPU Board.

3. Electronic 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.

Rules to ensure proper operation:

1. Each remote dispenser uses one 115V, 50/60 Hz or 230V, 50/60 Hz circuit for dispenser power. Put no more than two (2) dispensers on a circuit breaker (for Electronic Power).

2. Do not connect any other devices or motors to these circuits.

3. Put the pump wiring in its own 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 from the breaker panel to the dispenser.

WARNING: All Dispenser AC Power circuits (for Remotes 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

Connecting the Sub Pump Control Wiring 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. Red Jacket and F.E. Petro are two of the most common manufactur-

ers of submerged pumps. Check with those manufacturers for more information on control relay boxes.

Connect the “Motor Out” power wires between the dispenser and the control relay box for each product

as follows: Submerged Pump Motor Control - Connect to terminal 3 of TS2 on the CPU/Control board on side 1

of the dispenser. This should be a 14 ga. wire. If there is another CPU/Control board for this SAME PRODUCT, install a jumper wire between terminal 3 of TS2 of both boards. This allows terminal 3 of both boards to control the same submerged pump relay for that product. This should be a 14 ga. wire also. It is recommended that for Product “A” the Installer use a Blue wire for submerged pump motor control and if there is a second product (Product “B”) use a Brown wire for submerged pump motor con-

trol. 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 P2 on the CPU if the dispenser is controlling a submerged

pump relay. This will be set at the factory.

An RC Network is an electrical noise suppression device (see figure 37). It is used on AC power devices such as coils and across relay contacts (see figure 38). When AC voltage is applied to coils they are converted to electromagnets. Coils are used to operate AC devices, such as solenoid dispensing valves and AC power relays or contactors. W hen the AC power is removed from a coil, the electromagnetic field collapses. This causes an AC voltage spike as high as 1500 VAC which can affect electronic sys-

tems.
