LED ERROR - Detected Errors
This LED lights solid in conjunction with additional LEDs to indicate detected errors. In the case of
a detected error, the device transitions to the defined safe state. You must remove the cause of
the detected error and perform a power cycle of the device to exit the defined safe state and
resume operation. Contact your IDEC CORPORATION service representative if the condition
persists.
