1.7.5 Alarm signals
The equipment offers various possibilities for signalling alarm conditions, however, not for danger situations. They
are signalled optically (on the display as text) and electronically (pin/status output of an analog interface) and
digitally (digital 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
