4.2.3 Strategy 3, with defined valve stroke. (Only for devices from
software version 63)
With this option, only the Open position of the valve is calculated by working back from a set
path from the closing position. In order to close the valve, the actuator pushes out the tappet
until the set force is exerted on the valve (closing force for standard valves/valves with high
spring tension).
This calibration strategy is primarily to be used if the actuator tappet touches the valve tappet,
even if it is completely withdrawn, and measurements cannot be performed.
With a completely unknown valve, the 3 mm with closing force for standard valves value is a
usable starting value.
It is always recommended to use the closing force for standard valves first.
This setting is completely suitable for most valves.
The Valve with high spring tension setting should only be tried if you cannot close the valve.
This enables the current consumption to be increased to 15 mA during the pressing of the
rubber seal.
The sequence light comes on if this calibration method fails three times.
