14. Feedback Unit

See feedback module instructions for connections and calibration.

The P5 or EP5, Valve Control System, can easily be equipped with a Feedback

unit, model F5. This unit will mount directly on top of the Pneumatic positio-

ner replacing the positioner front cover. The O-ring located on the bottom of

the Feedback unit, F5, will provide the same sealing or draining capabilities

as the front cover. The indicator and front cover from the positioner unit can

then be installed on to the Feedback unit.

WARNING! Units installed in hazardous locations must have proper

approvals.

Installing the feedback unit.

— Remove the front cover, indicator, and Allen head screw from

the top of the positioner spindle.

— Install the drive coupling 4 and adjust the O-ring seal on the bottom in

either sealed or draining position. (See section 6, page 10).

— Install the Feedback unit 9 on top of the Positioner unit, making

sure the coupling is properly engaged before tightening the four

screws 5.

— Make electrical connections and tighten cable glands.

(See F5 manual for details).

— Adjust cams and/or potentiometer to desired position.

— Install the indicator and front cover.
