User Interface

Table 27 lists Controller Module diagnostic indications (Operator Interface messages, and Status LED) along with causes of the indications, automatic control file actions, and suggested user actions.

Hazardous voltages exist in the equipment enclosure.

Identify and avoid contact with voltage sources.

Disconnect power before servicing. (More than one switch may be required to disconnect all power.)

Failure to comply with these instructions could result in death or serious injury.
