Manual Override Test - 4-hose Mechanical PCU Option
Testing
12
Replace all wiring connectors (green) removed in step
from the Pump Control 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 start-up.
Manual Override Test - 4-hose Mechanical PCU Option
Note: The manual override test can only be performed on pumps/remote dispensers that are
connected to the 4-hose Mechanical PCUs.
The pumps and/or remote dispensers should be tested to verify AC wiring.
Note: Power up only the PCUs during these tests.
The following steps indicate the proper procedure for testing and the expected results. If any of
these tests fail, correct the wiring and re-do the test. Refer to
on
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.
Note: Ensure that the connectors are not touching any metal surfaces.
2
Turn on the breakers for all pumps and/or remote dispensers. If the TopKAT system and other
components are powered from the same breaker as the PCU, ensure that they are switched off
before proceeding.
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.
WARNING
Le courant alternatif est sous tension sur les bornes des modules de relais. Un choc
electrique peut se produire si l’operateur entre en contact avec ces connexions.
AVERTISSEMENT

In the PCU, turn the AC power and battery power switches to the ON position (up). These
switches are located in the upper right-hand 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.
