1.7.5 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) or electronic (pin/status output of an analog interface). All alarms
will cause the device to switch off the DC output permanently or temporarily.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DC output will be switched off temporarily
• 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 of the AC input circuit
• Critical on overvoltage! AC mains input circuit could be damaged
1.8 Technical Data
1.8.1 Approved operating conditions
• Use only inside dry buildings
• Ambient temperature 0-50°C
• Operational altitude: max. 2000 m above sea level
• Max 80% RH up to 30°C, linear decrease to 50% RH at 50°C
1.8.2 General technical data
Display: 7 segment type, 9 digits (upper row), 2x 4 digits (middle row), status symbols
