Module Fault Indicator

This red indicator is normally off. It turns on if there is a module fault in one

loop or both loops. Faults may be caused by:

loss of analog power

analog interface fault

memory fault

discrete input fault

transducer interface fault

excess following error

excess PID error

loss of feedback

hardware stop input

immediate stop command

Loop Active Indicators

Each of these green indicators is on when the corresponding loop is active. The

indicator blinks if a loop fault occurs and turns off if the loop is inactive.

Loop faults may be caused by loop failure or improper loop configuration.

Indicator Troubleshooting Guide

Refer to Table 11.A when using the indicators to diagnose module problems.
