Mounting and Set-up
Step 5: Mount the positioner on the actuator
and tighten the mounting screws.
Step 6: Insert the pneumatic fittings on the
positioner and actuator, run tubing from the
outputs of the positioner to the inputs of the
actuator.
NOTE: The supply air will output to Y1 in the
event of a signal loss (fail condition), in double
acting actuators - connect Y1 so that the
desired fail position will result. Single acting
units dearate Y1 upon loss of signal.

Selector’ yellow tab, to the 90° position - by
pushing it away from the labeled side of the
device.
Step 8: Adjust the yellow wheel underneath the
terminals using a 4 mm wide screwdriver to the
neutral position (Midway between 33° and 90°)
