Error detection The following errors are detected:
● Wiring error with short circuit to high
● Wiring error with short circuit to low
● Wiring error with short circuit between the
two channels
● Internal errors
In the case of an error, the control panel shows
the corresponding error message: F83xx
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 exter‐
nal free-wheeling arm has to be installed. The effective termi‐
nal voltage has to be < 25 V.
