Fig. 6 Positioner linkage
The positioning travel (stroke) is transmitted to the positioner via the bolt. You can adapt
the valve stroke range to the operating range of the position sensor by shifting the bolt in
the lever's oblong hole. A scale on the lever helps you to determine the valve stroke
range.
Use the lever scale to set the bolt to the appropriate position. A rough adjustment is suffi-
cient. The fine adjustment will be done later in the commissioning phase using the
Autostroke function.
