Initialization Procedure
PS2 Positioner Calibration Procedure Rotary Linear Actuators
6DR5x1, 6DR5x2 (x = 0,1,2,3,5,6)
Verify the positioner is mounted correctly using factory couplings to ensure there is NO
BACKLASH between the positioner input shaft and the actuator output shaft. Check that
there is sufficient supply pressure to operate the actuator/valve configuration. This is critical
on spring return (single-acting) actuators. Insufficient air pressure will result in a calibration
error.
Confirm a 4 20 mA source is properly connected to the 2-wire positioner (x = 0 or 1),
or a 2-, 3- or 4-wire positioner (x = 2 or 3).
Connect a 24 VDC power supply for Profibus
(6DR55) or Foundation Fieldbus (6DR56) for bench top configuration. For complete details
on the above, please refer to the "Operating Instructions" manual supplied on the CD in the
positioner’s box. Under the Navigation tab, expand "electropneumatic positioners" and then
"SIPART PS2". Choose input source, i.e. 4-20 mA = "SIPART PS2 with and without HART.
