Status Indicator

Indication: Status:

Off No power

Red Hardware or software error, power is low

Green Normal operation

Flashing Red Comm failure 1*

Flashing Red/Orange Expansion error

*1 Comm fail = communication cable disconnected, 100ms between valid frames, no more than

255 valid frames between valid frames addressed to module, 20ms idle time exceeded.

**2 COMM and STATUS will alternately flash when processor restart lockout is selected, a

fault has occurred and the processor is communicating with the module.
