1.7.5 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 (status output pin 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 due to high voltage entering the device or gener-
ated by the device itself due to a defect
•
Critical! The device and/or the source 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 output
Signal
OPP
(OverPower)
•
Shutdown of the DC input due to excess of the preset limit
•
Non-critical, protects the source from excessive power output
Signal
PF
(Power Fail)
•
DC input shutdown due to AC undervoltage or defect in the AC input
•
Critical on overvoltage! AC input circuit could be damaged
