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 (pin/status output of an analog
interface). All alarms will cause the device to permanently or temporarily switch off the DC output.
The meaning of the signals is as follows:
Signal OT • Overheating of the device
• DC output will be switched off temporarily
(OverTemperature)
• Non-critical
Signal OVP
• Overvoltage shutdown of the DC output due to high voltage entering the device or gen-
erated by the device itself due to a defect or because the adjusted OVP threshold was
(OverVoltage)
lower than the actual output voltage
• Critical! The device and/or the load could be damaged
Signal OCP • Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive current consumption
(OverCurrent)
Signal OPP • Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive power consumption
(OverPower)
Signal PF • DC output shutdown due to AC undervoltage or defect of the AC input circuit
• Critical on overvoltage! AC input circuit could be damaged
(Power Fail)
