1. COMMISSIONING
Setting:
1. If the required rev/stroke ratio of the actuator is communicated to the manufacturer
upon ordering, the actuator is correctly set in the factory.
2. Determine actuator revolutions per stroke (e.g. actuator speed per minute x acting
time in minutes).
3. Determine factory-preset range II or III. Determine actuator speed (via type designa-
tion on the actuator rating plate, e.g. D60 A-40 = 40 rpm)
Range III preset: actuators with output speed 5-50 rev/stroke.
Range II preset: actuators with output speed 25 -160 rev/stroke.
Alternative determination:
Turn sliding wheel into position 1. Perform approx. 13 handwheel turns while ob-
serving the mechanical position indication (if existing) or the operating cams of the
intermediate position switches. If the angle of rotation is > 150 , range III has been
preset otherwise range II.
4. Set the reduction gearing according to the calculated value by shifting the sliding
wheel with regard to table 1.1.
1.4 Setting the reduction gearing for part-turn
actuators
This limit switching unit is of similar design, however equipped with a reduction gearing
including mere 5 stages (refer to figure 1.5).
Figure 1.5: Setting the reduction gearing of the limit switching unit for part-turn actuators
The reduction gearing has a variable setting range, resulting from the plug-in sequence of
the gear wheels at the bottom of the mounting plate. The sections II (small on large gear
wheel) + III (large on small gear wheel) can be respectively preselected by exchanging the
gear wheels on the bottom of the limit switching base plate. For section I, use two gear
wheels of identical size. The setting options of this reduction gearing are specified in the
following table 1.2.
