STATUS LED DIAGNOSTICS
A Status LED is built into the 1243
window in the label on top of the controller. This Status LED displays fault
codes when there is a problem with the controller or with the inputs to the
controller. During normal operation, with no faults present, the Status LED
flashes steadily on and off. If the controller detects a fault, a 2-digit fault
identification code is flashed continuously until the fault is corrected. For
example, code "3,2"—main contactor welded—appears as:

( 3 , 2 )
The codes are listed in Table 8.

Note: Only one fault is indicated at a time, and faults are not queued up. Refer
to the troubleshooting chart (Table 7) for suggestions about possible causes of
the various faults. Operational faults—such as a fault in SRO sequencing—are
cleared by cycling the interlock switch or keyswitch.
