Automatic Initialization Of Linear Actuators - Siemens SIPART PS2 Operating Instructions Manual

Connecting the positioner
1. Connect a suitable power supply. The positioner is now in the "P manual mode". The current
potentiometer voltage (P) in percent is shown in the upper line of the display, e.g. "P37.5",
and "NOINI" flashes in the bottom line:
2. Connect the actuator and the positioner to the pneumatic lines.
3. Supply the pneumatic auxiliary power to the positioner.
Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire travel range. Move the
actuator to the respective end position for this purpose using the
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 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 reached. The closer this value
is to "P50.0", the more accurately the positioner determines the stroke travel.
The following applies to the flameproof enclosure version:
The inner friction clutch is fixed. Therefore, only move the outer friction clutch. This also
applies when using an internal NCS module.
The following applies to device versions without flameproof enclosure with internal
NCS module 6DR4004-5L.:
The inner friction clutch has no function. This means you should only adjust the adjustment
wheel of the magnet clamp. Requirement: 'YFCT (Page 42)' parameter is set.

Requirements
The following conditions must be fulfilled before activating the automatic initialization:
1. The actuator spindle can be moved completely.
2. The actuator spindle is at a central position after travel.
