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.

Step 7: Position the ‘Transmission Ratio

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°)
