Adjustment of position control on AG2

When executing the function M.Q0.TUNE the position control is
adjusted at the physical stroke of the proportional valve in use
and the required closing force is determined.
To this end, the seal closure point must be approached manually.
It is important that the valve is not entirely closed. Based on this
position the device uses an algorithm to calculate the optimum
force for sealing.
