Front Panel Alarm Led; P Ositions - Ametek Sorensen XG Operation Manual

Clearing Automatic Alarms
Some alarms will clear automatically when the condition that caused the
alarm is no longer present. When an alarm automatically clears, the
output voltage and current displays will return to normal, but the
ALARM LED will remain illuminated to indicate that an alarm has
occurred. If an automatic alarm is triggered, the normal alarm clearing
procedure still applies.
To clear the ALARM LED after an automatic alarm has cleared,
use one of the following methods:
For example, if one of the fans in the XG/XTR was temporarily blocked,
causing a Fan alarm, then the blockage was cleared and the fans
restarted, the alarm would clear. The output voltage and current displays
would be in normal mode, but the ALARM LED would be illuminated.
See "Front Panel ALARM LED" on page 3-23 for information on other
events that affect the ALARM LED.
Alarms status is tracked in the SCPI status registers. For more details on
how and where the alarms are tracked, see "Standard SCPI Register
Structure" on page 5-38.
