Chapter 5: Fault Check

Installation and Maintenance Manual

5.1: PLS Output Status on Fault Conditions

1) If a fault condition is detected, ALL limit switch outputs will turn off and the display will

show the following:

EE4 = Electronic Transducer Tracking Fault

No Message Microprocessor or 5 Volt Power Supply Failure

The message will remain on the display and the outputs will be off until the problem is

corrected and the fault reset button is pressed and released to reactivate the fault output

and return the display and outputs to their normal operation.

2) If the fault condition is the result of a microprocessor failure or lockup, the state of the

limit switch output circuits cannot be predicted. However, the fault check output will

turn off until the fault is cleared and the fault reset button is pressed and released.

Removal and reapplication of power to the PLS system may clear a locked-up

condition.
