HOW TO START-UP DISPENSER 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.
WARNING: MAKE SURE ALL DISPENSER POWER CIRCUITS FOR REMOTES ONLY ARE ON THE SAME PHASE/LEG OF THE
BREAKER PANEL OR DAMAGE WILL RESULT.
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 and 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 Lower I/O 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.
5. Make sure the 12-gauge green or green/yellow 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.
6. Turn on 120 or 240 volts ac dispenser power to the unit.
7. If the Circuit Breaker is a Hot/Neutral Breaker, make sure the Hot/Neutral Circuit Breaker is ON before taking measurements. Note:
The 120vac (HOT) wire will have power. MAKE SURE THIS LINE IS DISCONNECTED AND CAPPED DURING THIS STEP. Use a voltmeter
to verify 120 or 240 Volts AC only at Terminal 3 on TS1 of the 719 CPU board. Terminal 2 of TS1 on the CPU Board is Neutral. This AC
circuit provides power to the electronic boards.
8. Make sure displays are normal and not distorted.
9. Program the dispenser for Stand Alone operation in Menu Code 21.
10. Turn the circuit breakers to the motors back on.
CHECK THE PUMP MOTOR CIRCUIT!
REMOTE DISPENSERS
WARNING: TO PREVENT INJURY, MAKE SURE IMPACT VALVES AND SUBMERGED PUMP BREAKERS ARE OFF.
CAUTION: MAKE SURE THAT THE JUMPER BETWEEN J1-J3 (FOR PRODUCT A) AND THE JUMPER BETWEEN J2-J4 (FOR
PRODUCT B) ON THE CPU BOARD ARE PRESENT!
1. Lift Product A's lever. The dispenser's display will reset. Use a voltmeter to verify 120VAC on Terminal 2 of TS2 on the CPU Board and
use Terminal 2 of TS1 on the neutral.
2. Lower Product A's lever.
3. Repeat this process for the remaining levers. Product B can be measured on Terminal 4 of TS2 on the CPU Board.
4. To ensure that all dispensers are on the same phase, lift the lever for the same product on all dispensers at the same time. If any of
the dispensers are on a separate phase then the F6 Fuse (on the CPU Board) will blow. If this happens, resolve the issue by getting all
dispensers on the same phase and replace the fuse with another fuse that has the same ratings (1 Amp, Fast Acting 5mm x 20mm).
SUCTION PUMP
WARNING: IF THE LOWER DOOR ON THE PULLEY SIDE OF THE UNIT IS OFF, REPLACE THE DOOR, AND LOCK IT TO PREVENT
INJURY.
CAUTION: MAKE SURE THAT THE JUMPER BETWEEN J1-J3 (FOR PRODUCT A) AND THE JUMPER BETWEEN J2-J4 (FOR
PRODUCT B) ON THE CPU BOARD ARE PRESENT!
CAUTION: MAKE SURE THAT THE SWITCH ON THE PUMP MOTOR IS SWITCHED ACCORDING TO THE VOLTAGE USED TO
OPERATE IT. LOW = 120VAC OR HIGH = 240VAC!
