PSI 9000 WR 3U Slave Series
1.7.5 Alarm signals
Alarm conditions, not danger situations, are signalled on the front of this slave device in form of a red LED “
Error
”
(also see section
.). Because the models of this series are designed to run as slave units in a master-slave
system, the master unit will indicate alarms in its own available ways. Refer to the manual of series PSI 9000 WR
3U for more information about this matter.
The LED collects all of the below listed alarm situations. If there is supervision of the slave units being used, alarms
can be decoded by querying a status from the device via any of the two USB ports.
Global meaning of alarm situation as indicated by LED “Error”:
Signal
OT
(OverTemperature)
•
Overheating of the device
•
DC output will be switched off
•
Non-critical
Signal
OVP
(OverVoltage)
•
Overvoltage shutdown of the DC output due to high voltage entering the device or gener-
ated by the device itself due to a defect
•
Critical! The device and/or the load could be damaged
Signal
OCP
(OverCurrent)
•
Shutdown of the DC output due to excess of the preset limit
•
Non-critical, protects the load from excessive current consumption
Signal
OPP
(OverPower)
•
Shutdown of the DC output due to excess of the preset limit
•
Non-critical, protects the load from excessive power consumption
Signal
PF
(Power Fail)
•
DC output shutdown due to AC undervoltage or defect in the AC input
•
Critical on overvoltage! AC input circuit could be damaged
