LED DIAGNOSTICS

During normal operation, with no faults present, the LED on the controller's
front face flashes a single flash at approximately 1 flash/second. If the controller
detects a fault, a 2-digit code (see Table 2) is flashed continuously until the fault
is corrected. For example, code "3,2"—welded direction contactor—appears as:

: Only one fault is indicated at a time, and faults are not queued up.
NOTE
Operational faults—such as a fault in SRO sequencing—are cleared by cycling
the brake/seat switch or keyswitch. (See "Fault recovery" in Appendix A for more
information.)
