This parameter is entered in 0,0 1% units.
The offset value is added to the output value. Valve zero offsets can be compensated with this parameter.

This command is used to define the output signal (voltage or current) and to change the polarity
12
.
Differential output ± 100 % corresponds with ±
10 V (0… 10 V at PIN 15 and PIN 16).
Current output ± 100 % corresponds with
4… 20 mA (PIN 15 to PIN 12). 12 mA (0 %) = center point of the
valve.
An output current of << 4 mA indicates an error and the module is disabled. The current input of
the proportional valves should be monitored by the valve. The valve have to be deactivated in case
of < 4 mA input signal. Otherwise the EOUT command can be used to get a defined output signal.

The older POL command is removed.
