Connecting Console to Pump Wiring
General Wiring Practices
1. Be sure all wires are color-coded or carefully marked to identify their source.
2. The Wireless PLLD Controller Module in the Console comes with a connector in place. Do not remove the
connector from the module or remove the module from its slot in the console during wiring. Terminal
identifications appear only on the module bracket. Removing the connector from the module increases the risk of
wiring errors.
3. Label all connectors using the self-adhesive labels supplied according to the slot in which the modules are installed.
IMPORTANT! Once a connector has been wired on a module and the Console has been programmed, the connector
and module cannot be moved to another slot without reprogramming the system. For consistency in programming,
we recommend labeling the lines with the same product descriptions as those used for the tanks.
4. Record the location (i.e., Line #1 (regular), Line #2 (super), etc.) of each submersible pump wired to a module on the
circuit directory inside the Console door.
Pump Control Wiring for Red Jacket and Other Pumps
IMPORTANT! Line Leak Detector wiring for Red Jacket submersible pumps is different than wiring for other pumps.
See Figure 5-1 on page 5-2 or Figure 5-2 on page 5-3 for the appropriate wiring diagram.
The Console must be able to detect when dispensers are ON or OFF so it only initiates line leak tests when the dispenser
is OFF. The console must also be able to start the submersible pump to perform a line leak test, and shut the pump off if a
leak is detected.
To enable this feature, interrupt the AC Line between the “Dispenser ON Switch” and the pump contactor. You can
usually break the AC Line from the “Dispenser ON Switch” in the submersible pump relay control box.
The “Dispenser ON” signal may come from a Point-of-Sale terminal, self-serve console or switch or relay inside the
dispenser, from which the AC Line will enter the pump relay control box.
IMPORTANT! The Console, when wired correctly, will control the pump independent of the dispenser control
circuits. It is imperative that when the Emergency Stop switch is wired and tested that the Console’s pump control
circuitry CANNOT turn On the pump. To ensure that the pumps are unable to be activated in an emergency
situation, it is best to have the Emergency Stop switch interrupt pump power at the circuit breaker panel via
shunt breakers.
WARNING
TURN OFF, TAG, AND LOCKOUT POWER TO THE CONSOLE, DISPENSERS, AND
SUBMERSIBLE PUMPS WHILE CONNECTING CONSOLE TO PUMP WIRING.
This equipment uses lethal voltages and attaches to accessory components which operate in
areas where flammable liquids and vapors may be present, THEREFORE:
Use only supplied service parts to avoid compromising safety.
Do not allow WPLLD pump control wires to share conduit with wires from intrinsically safe de-
vices such as probes and sensors.
Ensure that any assembled conduit only enters the console through the properly designated
knockouts.
Wiring must comply with all applicable requirements of the National Electrical Code; federal,
state, and local codes; and any other safety codes.
