Lights to indicate when the unit is in Standby mode. Behavior of the unit
in Standby (Output off) is determined by the options chosen for Load
Type (see PAR. 3.3.6). If the Load Type is ACTIVE (default), then in
Standby mode the unit is set to voltage mode, voltage is set to zero, cur-
rent protection is set to the nominal, and voltage limit is set to maximum.

Lights when a fault is detected. The failure of the following assemblies
cause the FAULT indicator to go on: A1 (any control function failure), A2
(overtemperature, instant internal overcurrent, output overvoltage/over-
current, local +15V failure), A4 (input under/overvoltage, input overcur-
rent, internal output under/overvoltage, internal output overcurrent,
overtemperature, fan failure, local –15V failure). When the FAULT indica-

B-5, Appendix B for details), however the FAULT indicator remains lit.
When the fault has been removed, normal operation is restored by
cycling power off, then on (preferred) or by briefly pressing the RESET
key on the front panel to initiate a shut down and power up sequence
(see RESET key, Table 3-2).
