Mechanical mounting
3.1 Mounting to linear actuators
3.1.1 Preparation of the valve actuator
¬
The actuator must be in the zero position
(actuator vented).
¬
Should there be an optical position
indicator in the actuator (a red spindle), it
must be removed.
3.1.2 Assembling the travel sensor
DANGER
Pretensioned spring!
P
Damage to the device.
●
Slowly relax spring.
Attention:Damage to the spindle
surface may lead to failure of the
travel sensor!
The travel sensor is assembled using a
mounting kit 1436S01Z... (direct mounting)
or 4232S01Z... (remote mounting)
consisting of a spring, an operating bush
and a threaded adapter (if applicable). The
mounting kit depends on the valve type.

1. Pull out the spindle of the travel sensor up to
the limit stop.
2. Push the spring over the spindle.
3. Fix the spindle at point
a
(the spindle must not be damaged
during this process).

Assemble the travel sensor (see chapter
3.1.2 “Assembling the travel sensor”).
¬
Mount the positioner

.
The positioner must not be
fixed by turning the housing as
this may result in the danger of
overturning the internal stop.
