Initialization Of Linear Actuators - Siemens SIPART PS2 Installationsanleitung

7. The display of the potentiometer voltage in % (upper line of the display) must always remain in the range
P5.0 to P95.0. If that is not the case, adjust the friction clutch (8, Fig. 3) as follows: Move the actuator into
its final position by pressing the
between P90.0 and P95.0.
8. Move through the entire range by adjusting the actuator with the
position. The potentiometer voltage should now remain in the range P5.0 to P95.0. If that is still not the case,
adjust the friction clutch (8, Fig. 3) as follows: Move the actuator into its final position again by pressing the
key. This time adjust the friction clutch until the upper line of the display shows a value between P5.0
and P10.0.
9. Now move the actuator into the horizontal position of the lever. The display should show a value between
P48.0 and P52.0. If that is not the case, adjust the friction clutch (8, Fig. 3) until "P50.0" is shown when the
lever is horizontal. The more precisely you achieve that value, the more accurately the positioner can deter-
mine the displacement.

Initialization of linear actuators

If you can move the actuator correctly, leave it in a central position, and start automatic initialization:
1. Press the mode key
Display:
2. Switch to the second parameter by pressing the mode key
Display:
Note
This value must match the setting of the leverage ratio switch (7, Leaflet "Operation – a concise
overview") (33 or 90 )
3. Switch to the following display with the mode key
Display:
You only have to set this parameter if you want to have the calculated total stroke displayed in mm at the
end of the initialization phase. To do that, select the same value in the display as the value to which you set
the driver pin on the scale of the lever.
4. Switch to the following display with the mode key
Display:
5. Start initialization by pressing the
Display:
During the initialization process "RUN1" to "RUN5" appear one after the other in the lower display.
Note
The initialization process can take up to 15 min depending on the actuator.
Initialization is complete when the following display appears:
After you have pressed the mode key
