7 – Pump/Dispenser Manual Test
Verify General Guidelines
Verify that the general guidelines listed below were met when installing the system’s pumps
and dispensers. If your system contains any electronic pumps, follow the appropriate
installation manual for applicable tests.
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.
Manual Override Test
The pumps and/or dispensers should be tested to verify AC wiring. 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 5-3 on page 38 for location of the override
switches.
1 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.
2 Turn on the breakers for all pumps and/or dispensers.
Power up only the pump control unit(s) during these tests!
WARNING
Do not turn on the AC power for the site controller, monitor, checkpoint, profit
point, etc.
