5.11 Digital status signals
For reporting the status of the generator, the following signals can be found on the 25-pin sub-D
connector.
Operating Indicates whether the generator is operational.
Limit Detect Indicates that the output voltage or current is limited.
Arc Detect Indicates that an arc has been detected.
5.11.1 Operating signal
The connection of the operating signal must be between pin 10 (OC) and 23 (OE) as indicated
in the diagram below. The maximum current is 10 mA. When connecting make sure the polarity
is correct.

5.11.2 Pin 9 output select: limit alarm/arc detect
The connection of the limit alarm/arc detect signal must be between pin 9 (OC) and 22 (OE) as
indicated in the diagram below. The maximum current is 10 mA. When connecting make sure
the polarity is correct.
