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 turns/stroke. Refer
to <Gear stage of the reduction gearing: test/set>.
11.2.2.
Gear stage of the reduction gearing: test/set
The test/setting is only required if the mechanical position indicator cannot be correctly
set.

Refer to table and check if turns/stroke correspond to the setting of the reduction
gearing (stages 1– 9).
