PLC RESET / RELAY REPLACEMENT

The PLC (Programmable Logic Controller) requires a relatively constant source of electrical power.

Power surges, outages or drops in power can cause the PLC to lose its settings.

This may result in missing or misplaced information on the controller screen.

Resetting the PLC to its original settings is a simple procedure:

• Open the electrical enclosure.

• Power up the electronic test bench from the main power switch. The test bench must be powered on

during the PLC reset procedure.

• Move the three position toggle switch on top of the PLC right to the

RUN

position.

• Return the toggle switch to the center

• Cycle the main power off and back on.

• The PLC and the electronic test bench should now operate normally.

• Close the electrical enclosure.

Relay Replacement:

• There are 3 relays which control the Water Inlet, (HIPCO) Dump Valve, and Pump Valve functions of

the electronic test bench. If one of these functions is inoperable these relays can be replaced.

• All 3 relays are identical and interchangeable.
