PUMP/DISPENSER MANUAL TEST
1. Verify that the general guidelines listed below were met when installing the system's pumps
and dispensers.
Suction Pumps
The CFN System is capable of directly driving pump motors up to 3/4 HP at 120/240 VAC or
1-1/2 HP at 240 VAC. A starter relay must be used with pump motors exceeding these
limitations. A separate circuit breaker should be supplied for each pump to meet the current
requirements and to allow for isolated control with the circuit breaker panel in case of
problems.
Dispensers
The CFN System is capable of directly driving submersible pumps up to 3/4 HP at 120/240
VAC or 1-1/2 HP at 240 VAC. A dispenser with a submersible pump exceeding these
limitations will require the use of a submersible starter relay. A separate circuit breaker
should be supplied for each dispenser in cases where it will directly drive the submersible
pump. Dispensers may be grouped together on a single breaker when the submersible
pump has its own breaker. It is recommended that no more than two dispensers be powered
from one breaker to maintain isolated control with the circuit breaker panel in case of
problems.
2. Manual Override Test: The pumps and/or dispensers should be tested to verify AC wiring.
POWER UP ONLY THE PUMP CONTROL UNIT(S) DURING THESE TESTS! The steps
below indicate the proper procedure for testing and the expected results. If any of these
tests fail, correct the wiring and perform the test again. See Figure 5-1 for location of the
override switches.
a. Remove all wiring connectors (green) from the pump control I/O board located in the
front of the card cage. This will prevent any damage to the PCBs if wiring is incorrect.
Make sure connectors are not touching any metal surfaces.
b. Turn on the breakers for all pumps and/or dispensers. DO NOT TURN ON THE AC
POWER FOR THE SITE CONTROLLER, ISLANDER, CRT TERMINAL,
CHECKPOINT, PROFIT POINT, ETC.
c. Turn the AC power and battery power switches, in the pump control unit located in the
upper righthand corner of the power supply, to the
ON position (up).
CAUTION
AC power is present on the terminal blocks in the pedestal. Electrical shock may
occur if the operator comes in contact with these connections.
d. Place the system override switch for Hose 1 in the MAN (manual) position.
e. Turn on Hose 1. After completing reset, the hose should be able to dispense product.
f. Turn on all other hoses. No other hoses besides 1 should activate.
