chapter 6.1.
The mechanic assembly of the proximity switches is carried out
at the actuator of the corresponding double seat valves.
Observance of the operating manual for double seat valves
is essential!

3.
Check the solenoid valves by turning the handle on the upper
side of the valve by 90°.
4.
Check the valve position indicator.
The proximity switches are installed at the double seat valves
with a mechanical stop.
Adjustment is not required!
The following allocation applies for double seat valves:
Closed valve position feedback – sensor 1 controlled
Open valve position feedback – sensor 2 controlled
Check the proper fit of the proximity switches to provide for
the accurate transfer of the signals for the corresponding
