Assembly Of Linear Actuator > 14 Mm - Siemens 6DR4004-6NN Series Operating Instructions Manual

Preparing for Operation
3.1.3 Assembly of linear actuator > 14 mm
(seee Figure 6, page 54)
1. Mount clamping assembly (3) with socket head screws (17) and lock
washers (16) on the actuator spindle.
2. Insert the pick-up bracket (2) into the recesses of the clamping assem-
bly. Set the required length and screw only so tight that the pick-up
bracket can still be shifted.
3. The center of the pin (4) is set to the value of the stroke range specified
on the actuator or set to the next large scale value. The same value can
be set later for 3.YWAY during start-up, to display the travel in mm after
initialization.
4. Push the lever onto the positioner shaft as far as possible, and secure
with the socket head screw (17).
5. Attach the mounting bracket (1) to the NCS mounting set using the two
hexagonal head screws (9), spring washer (10), U washer (11) and
hexagon nut (21).
6. Selection of the row of holes depends on the width of the actuator yoke.
The driver pin (4) should engage in the pick-up bracket (2) as close to
the spindle as possible, but must not touch the clamping assembly.
7. Hold the NCS mounting kit with the mounting bracket (1) on the actua-
tor such that the driver pin (4) is guided within the pick-up bracket (2).
8. Tighten the pick-up bracket.
9. Position the mounting parts according to the type of actuator:
- Actuator with ledge: hexagonal head screw (8), U washer (11)
and spring washer (10).
- Actuator with plane surface: four hexagonal head screws (8) with
U washer (11) and spring washer (10).
- Actuator with columns: two U bolts (7), four hexagonal nuts (21)
with U washer (11) and spring washer (10).
10. Secure NCS mounting kit onto the yoke using the previously positioned
mounting parts.
