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.
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
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.
There are no torn cables or stranded
