Error detection
1) At a maximum switching frequency of 1 Hz
2) In the case of inductive loads with currents > 200 mA or in the case of
inductive loads with a greater energy content, an external free-wheeling arm
has to be installed. The active clamping voltage has to be < 25 V.

The following errors are detected:
● Wiring error with short circuit after High
● Wiring error with short circuit after Low
● Wiring error with short circuit between both channels
● Internal error
In the case of an error, the control panel shows the corre-
sponding error message: F83xx
