Bennett 3000 Spec 300 Series Instruction Manual Dispenser Operation
34
The suction pump's motor for Product A has two wires coming into the electrical enclosure.
One motor wire connects to TS2, terminal 2 of the CPU Board (factory connected) and the other wire is left detached for the
installer to connect the pump motor's neutral, which comes directly from the Circuit Breaker or Phase 2 if using 240 volts to run
the Product A motor.
The Hot wire for the suction pump's motor comes directly from the Circuit Breaker for Product A and connects to TS2, terminal
1 of the CPU Board.
If this is a two product pump, then the wire from the Product B motor goes to TS2, terminal 4 of the CPU Board (factory
connected) and the other wire is left detached for the installer to connect the pump motor's neutral, which comes directly from
the Circuit Breaker or Phase 2 if using 240 volts to run the Product B motor.
The Hot wire for the suction pump's motor comes directly from the Circuit Breaker for Product B and connects to TS2, terminal
3 of the CPU Board.
1. Turn on the Product A's pump motor's Circuit Breaker. With the lever lowered, use a voltmeter to verify that 120vac is on TS2,
terminal 1 of the CPU Board. If the pump's motor is switched to high (240VAC) then verify that 120VAC is on the wire that the
installer connected directly from the circuit breaker to the pump motor's wire.
2. Turn off the Product A's pump motor's Circuit Breaker.
3. Repeat this test for Product B using TS2, terminal 3 of the CPU Board for 120vac. If the pump's motor is switched to high (240vac)
then verify that 120VAC is on the wire that the installer connected directly from the circuit breaker to the pump motor's wire.
HOW TO PURGE PRODUCT LINES FOR REMOTE DISPENSERS
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.
Turn off the breaker to the submerged pump before removing the plug. Remove the plug and insert a hose with a ball valve to control
fuel leakage. Turn on the breaker to the submerged pump after connecting the hose. Turn on the submerged pump and open the ball
valve until fuel begins to come out. After fuel comes out close the ball valve, turn off the submerged pump using the circuit breaker, drain
the hose by opening the ball valve, remove the hose, and reinsert the plug. 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 EMERGING 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.
