Description
Normally, the valve range is determined automatically during Autoadjust. A partial run of
Autoadjust that is limited to the control parameters or valves and fittings without end stops,
however, requires manual adjustment of the valve range.
CAUTION – Risk of crushing!
Following manual adjustment of the end positions, it is essential that the
parameter "Control at 100 %" is set to "On". Otherwise, the valves and fittings
may be driven at full speed to an end position.
Do not reach into the adjustment mechanism.

The working range can be configured to be smaller than the maximum mechanical working range.
The setpoint range always refers to the configured working range. Use this parameter to specify
the lower limit of the working range.
CAUTION – Risk of crushing!
This function is only active in control mode. In the event of a power supply failure
(electric or pneumatic), and in manual mode, the mechanical end positions are
approached.
