1.7.5 Alarm signals
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output.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DCoutputwillbeswitchedo
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC output occurs due to high voltage being generated by
the device or is entering the device from outside
• 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 drain
Signal OPP
(OverPower)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive power drain
Signal PF
(Power Fail)
• DC output shutdown due to AC undervoltage or internal auxiliary supply defect
• Critical on AC overvoltage! AC mains input circuit could be damaged
