Instructions for Calibrating Siemens PS2 Positioners
Linear Valves
1. Assemble valve as normal.
2. Securely mount the take off plate and take off arm to the valve stem and secure.
3. Loosely mount the positioner to the bracket.
4. Set the ratio bar on the positioner to the proper setting for the valve stroke.
5. Lock the ratio bar with the small wheel lock located inside of the positioner. This
must be locked in the 33º position if the stroke is less than 20 mm, or 90º for
strokes longer than 20 mm.
6. Apply 35 psi to the supply port on the positioner for reverse acting valves, and 25
psi for direct acting valves.
7. Apply 4.0 mA to the proper terminals.
8. Using the ‘+ / -’ keys, move the valve to the 50% open position.
9. Adjust the position of the positioner so that the take off arm for the positioner is
parallel with the actuator and horizontal to the positioner.
10. Securely lock the positioner and bracket in place with the mounting bolts.
11. Set the friction clutch to read somewhere between 48.0 and 52.0. The closer you
get to 50.0, the more accurate the performance will be.
12. Hold the ‘Hand’ key down for 5 seconds to get into the menu mode.
13. Set the menu items as instructed on the following pages 8-10 to match the type of
valve you have.
14. Once the programming changes are made for the specific valve, run through the
automatic initialization on menu #4. Simply press and hold the ‘+’ key for 5
seconds to start the process.
15. After the initialization completes, lock down the friction clutch to prevent further
adjustment. This is done with a screwdriver in the slot below the thumb wheel.
16. Momentarily press the ‘Hand’ key to get back to the main menu.
17. If any values have changed after locking down the friction clutch, simply re-
initialize the positioner again to make sure the shift is learned by the positioner.
18. Press and hold the hand key for 5 seconds to get out of the menu mode.
19. Press the ‘Hand’ key one more time momentarily to get into Automatic mode.
20. Valve is ready for operation.
