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 switch off the DC input.
The meaning of the signals is as follows:
Signal OT
• Overheating of the device
(OverTemperature)
• DC input will be switched off
• Non-critical
Signal OVP
• Overvoltage shutdown of the DC input occurs due to high voltage entering the device
(OverVoltage)
• Critical! The device and/or the load could be damaged
Signal OCP
• Shutdown of the DC input due to excess of the preset limit
(OverCurrent)
• Non-critical, protects the source from excessive current drain
Signal OPP
• Shutdown of the DC input due to excess of the preset limit
(OverPower)
• Non-critical, protects the source from excessive power drain
Signal PF
• DC input shutdown due to AC undervoltage or defect in the AC input
(Power Fail)
• Critical on overvoltage! AC mains input circuit could be damaged
