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.
Figure 72: Operation in direction OPEN (left) and position OPEN (right)
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 turns/stroke. Refer
to <Gear stage of the reduction gearing: test/set>.
10.2.2. Gear stage of the reduction gearing: test/set
The test/setting is only required if the mechanical position indicator cannot be correctly
set.
1. Refer to table and check if turns/stroke correspond to the setting of the reduction
gearing (stages 1– 9).
