14. Feedback unit (P5 or EP5)
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 positio-
ner 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.
