Siemens SIPART Series - 7.4.2 Automatic initialization of linear actuators

Commissioning
7.4 Commissioning linear actuators
SIPART PS2 with and without HART
124 Operating Instructions, 10/2013, A5E00074631-11
Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire actuating range.
Move the drive to the respective end position for this purpose using the
or button.
Note
End position
By simultaneously pressing the
and buttons, you reach the end position faster.
2. Now move the actuator to the horizontal position of the lever.
3. A value between "P48.0" and "P52.0" is shown on the display.
4. If a value beyond this value range is shown on the display, you must move the friction
clutch. Move the friction clutch until a value between "P48.0" and "P52.0" is achieved.
The closer this value is to "P50.0", the more accurately the positioner determines the
stroke travel.
Note
The following is applicable for the flameproof enclosure version:
The inner friction clutch is fixed. Therefore, only move
the outer friction clutch.
