MANUAL OVERRIDE TEST
NOTE: The manual override test can only be performed on pumps/remote dispensers that are
connected to CFN pump control units (PCUs). For testing of electronic pumps/remote
dispensers, refer to the manuals supplied with the pumps/remote dispensers.
The pumps and/or remote 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 re-do the test.
See the Terminal Block ID diagram in Section 4 for the location of the override switches.
1.
Remove all wiring connectors (green) from the Pump Control I/O PCB assembly located in
the front of the card cage. This will prevent any damage to the PCBs if the wiring is incorrect.
Make sure the connectors are not touching any metal surfaces.
2.
Turn on the breakers for all pumps and/or remote dispensers. If the site controller and other
components are powered from the same breaker as the pump control unit (PCU), be sure
that they are switched off before proceeding
CAUTION
AC power is present on the terminal blocks of the relay modules. Electrical shock
may occur if the operator comes in contact with these connections.
3.
In the PCU, turn the AC power and battery power switches to the ON position (up). These
switches are located in the upper righthand corner of the power supply.
4.
Place the system override switch for hose #1 in the MAN position.
5.
Turn on hose 1. After completing reset, the hose should be able to dispense product.
6.
Turn on all other hoses. No other hoses besides hose 1 should activate.
7.
Turn off all hoses.
8.
Place the system override switch for hose 1 in the ON position.
9.
Repeat Steps 4 through 8 for all remaining hoses. Substitute the hose under test for hose 1.
10. Turn off the AC power and battery power switches in the PCU.
11. Turn off the breakers for all pumps and/or remote dispensers and the site controller and other
components.
12. Replace all wiring connectors (green) previously removed from the Pump Control I/O PCB
assembly.
NOTE: The manual override test will uncover most point-to-point AC wiring mistakes that can
occur. The automatic test performed during the system start-up will complete the
verification of correct AC wiring to the pump/remote dispensers. The automatic test
should only be performed at the start-up.
