1.7.5 Alarm signals
The equipment offers various possibilities for signaling alarm conditions, however, not for danger situations. The
signals are optical, as text on the displays. All alarms will cause the device to switch off the particular DC output.
The two displays and their knobs are assigned to two separately adjustable and working DC output. The third output
is an auxiliary one and can only be adjusted in a very limited range by a trimmer. It doesn’t feature any protections.
Following applies:
•
The left-hand display is assigned to the lower pair of DC output sockets and is called “output 1”
•
The right-hand display is assigned to the middle pair of DC output sockets and is called “output 2”
• The upper pair of DC output sockets form “output 3”
The meaning of the signals on the display of output 1 and 2 is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
•
DC output will be switched off
•
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
