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 digital. All alarms will cause the device to switch off the DC input
or prevent it from being switched on.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the electronic load module
• DC input will be switched off
• Non-critical
Signal OVP
(OverVoltage)
• Shutdown of the DC input due to excess of the preset limit
• Critical! The device could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from excessive current drain
Signal OPP
(OverPower)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from excessive power drain
Signal PF
(Power Fail)
• DC input shutdown due to AC undervoltage or defect in the AC input or due to overheat-
ing of the DC-AC inverter stage
• Critical on AC overvoltage! AC mains input circuit could be damaged
Signal Sense
• Sense connection not wired resp. connection has been interrupted or the max. possible
voltage compensation for remote sensing has been reached
• Non-critical, but requires interaction by the user
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: Colour touch screen, 320pt x 240pt, resistive
