Operation

6.2.2System MODE Indicators

The Liebert FS has nine modes of operation: OFF, STARTUP, CHARGE, READY, DISCHARGE, SHUTDOWN, COAST, FAULT and STANDBY. These are displayed on the main screen of the control panel as identified in Figure 55. Table 5 lists the system Modes along with the corresponding Con- tactor Status, and the Conditions required to operate in these Modes: external voltage range, speed and command.

NOTE:

See 5.3 - Modes of Operation for further details on modes of operation.

6.2.3System STATUS Indicators

The Liebert FS system displays multiple status conditions during operation. Table 6 shows the com- plete list of status indicators for the Liebert FS and the corresponding condition.

Table 6 System status indicators

 

Message
