Manual Override Test
Note: The manual override test can be performed only on pumps/remote dispensers that are
connected to CFN PCUs. For testing of electronic pumps/remote dispensers, refer to
manuals supplied with the pumps/remote dispensers.
The pumps and/or remote dispensers should be tested to verify AC wiring.
Note: Only PCUs should be powered up during these tests.
The steps below list the testing procedures and expected results. If any of these tests fail,
correct the wiring and repeat the test. See the Terminal Block ID diagram in
“Pump/Remote Dispenser Wiring” on page 43 for the location of 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 damage to PCBs if the wiring is incorrect. Ensure
that connectors are not touching any metal surfaces.
2 Turn on the breakers for all pumps and/or remote dispensers. If the SC and other components
are powered from the same breaker as the PCU, ensure that they are turned off before
proceeding.
AC power is present on the terminal blocks of relay modules. Electrical shock may occur if the
operator comes in contact with these connections.
WARNING !
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 the 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 to 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.
