DIAGNOSTICS AND TROUBLESHOOTING

Diagnostic information is provided by the fault codes flashed by the Status
LED, the fault display on the Spyglass gauge, and the Faults menu on the 1311
programmer. Refer to the troubleshooting chart at the end of this section for
suggestions covering a wide range of possible faults.

LED DIAGNOSTICS

The Status LED output at J1-Pin 17 provides either fault codes (Table 3) or fault
categories (Table 4), depending on how the Fault Code parameter is set. The
built-in Status LED located on top of the controller always provides fault codes.
LED Fault Codes
During normal operation, with no faults present, the Status LED flashes steadily.
If the controller detects a fault, a 2-digit fault code is flashed until the fault is
corrected. For example, code "3,2"—main contactor fault—appears as:
