Theequipmento󰀨ers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o󰀨theDCterminal.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DCterminalwillbeswitchedo󰀨
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC terminal due to high voltage entering the device or
generated 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 terminal due to excess of the preset limit
• Non-critical, protects the load or source from excessive current consumption
Signal OPP
(OverPower)
• Shutdown of the DC terminal due to excess of the preset limit
• Non-critical, protects the load or source from excessive power consumption
Signal PF
(Power Fail)
• DC terminal shutdown due to AC undervoltage or defect in the AC section
• Critical on overvoltage! AC section could be damaged
