Troubleshooting Guide
If the Utility Controller fails to energize, follow these procedures:

Verify that the Controller has correct line voltage connected. With the control switch in the ON
position, the PLC “PWR” light should be illuminated. If it is not, check the wiring connections.
Remove the wiring junction-box cover and examine wiring connections.

Verify that Touchscreen turns on and initializes.

Touchscreen should start-up on the Home Screen.(Refer to Users Guide)
 Verify that PLC Mode switch is set to “RUN” position.

Verify that the Door Panel plug is securely connected to the door terminal.

Check the wiring terminals on the door panel to verify that none has become damaged or disconnected
during installation. Reconnect, if necessary.
If services do not turn on with switches:
1.
Verify that PLC Mode switch is set to “RUN” position.
2. Verify proper voltage at corresponding posts on Terminal 2.
3. If you do not read the correct voltage at the terminal posts, contact an ISIMET Service
Representative.
4. If you read the correct voltage, test the remote relay and/or solenoids to verify that they are
operational.
In many cases, failure of the system is the result of improper connection of a remote service or device such
as a remote relay, solenoid or building alarm system. Refer to
Equipment Specifications to confirm that
correct connections to these services and devices have been made.
Notes:

Damage to the Electronic Controller and other components can occur from improperly connecting the
services, overloading the output circuits, or failing to follow all start-up tests and checklists.

In ALL cases, if the system fails or you have questions about the equipment, contact an ISIMET
Service Representative.

If the results of all test procedures are positive but utilities will not activate, ISIMET recommends that
you examine and test the various utility services controlled by the unit to verify that they are
operational and active.
If utilities or controlled devices remain operational after the service switch is disengaged, check for the
following before placing the unit into full operation:

A defect in the remote relay or solenoid

Tampering

The remote relay unit has a control switch with a manual operation position and the switch is in the
manual position.
If utilities or devices continue to be active or if you have a question about the operation of the unit,
contact an
ISIMET Service Representative immediately.
