Alarm signals
The device offers various possibilities for signalling alarm conditions, however, not for danger situations. The sig
-
nals 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 input.
The meaning of the signals is as follows:
Signal
OT
(OverTemperature)
•
Overheating of the device
•
DC input will be switched off
•
Non-critical
Signal
OVP
(OverVoltage)
•
Overvoltage shutdown of the DC input occurs due to high voltage entering the device
•
Critical! The device and/or the load could be damaged
Signal
OCP
(OverCurrent)
•
Shutdown of the DC input due to excess of the preset limit
•
Non-critical, protects the source from excessive current drain
Signal
OPP
(OverPower)
•
Shutdown of the DC input due to excess of the preset limit
•
Non-critical, protects the source from excessive power drain
Signal
PF
(Power Fail)
•
DC input shutdown due to AC undervoltage or defect in the AC input
•
Critical on overvoltage! AC mains input circuit could be damaged
