9. Setting the position switches
The standard position switches serve to switch off the motor when the desired limits are reached.
Additional position switches are potential-free opening/closing contacts and serve to indicate the valve position.
They are available as accessories. The switches are activated by cams. These cams are stepless adjustable on their
shaft by means of a friction coupling.
NOTE:
Use the bridge in figure 11, item 3 as support for the screw driver when adjusting the cams.
