Alarm signals
The equipment offers various possibilities for signalling alarm conditions, however, not for danger situations. The
signals may be optical (on the display as text) acoustic (piezo buzzer) or electronic (pin/status output of an analog
interface). All alarms will cause the device to switch off the DC output.
The meaning of the signals is as follows:
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
