The self-adjusting mechanical position indicator shows the valve position by means
of an arrow
. When correctly set, the arrow points to symbol
(OPEN) or
(CLOSED) in the end positions.
Information
The position indications is housed in the actuator switch compartment. Opening the
switch compartment for manual setting is only necessary if the gear stage setting
must be modified of if the factory settings of predefined end position CLOSED (or
OPEN) must be adapted when commissioning.
11.2.1.
Mechanical position indicator: set
1.
Move valve to end position CLOSED.
2.
Push both lower discs with the symbols
(OPEN) and
(CLOSED) towards
each other. The disc with the arrow is thereby
is driven:
Figure 87: Setting position in CLOSED
3.
Move actuator to end position OPEN.
➥
The arrow
rotates in direction OPEN driving the indicator disc with symbol
(OPEN) until the actuator stops in position OPEN.

4.
Check settings:
➥
The setting of the mechanical position indicator is correct if the angle between
the symbols
(OPEN) and
(CLOSED) ranges between approx. 120° and
280°.
➥
If all three discs are turned at the same time, the indicator can be shifted in
steps of 15°. Individual shifts of 5° are possible.
➥
If the indicator is rotated too far (more than 280°) or if the angle is too small
(below 120°), adapt the gear stage setting to the actuator swing angle. Refer
to <Gear stage of the reduction gearing: test/set>.
