Type3730-0 ElectropneumaticPositioner
This quick guide does not replace the mounting and operating
instructions supplied with the positioner. Observe the safety
instructions as well as the warning and caution notes specied in the
mounting and operating instructions.

30 355, 700, 750 M50
ÎTo mount the positioner, lift the lever so that the follower pin rests
on the follower clamp of the actuator stem. Make sure the lever
can move freely.

200 See manufacturer's specications XXL 300
ÎDetermine the travel range of the control valve (CLOSED position
to as far it will go in the other direction) by applying the max.
supply air to the actuator and then venting the actuator completely.
Î
Fasten the lever with the follower pin onto the shaft of the
positioner.
Î
Fasten the NAMUR bracket onto the valve yoke so that it is aligned
centrally to the slot of the follower plate when the travel position
is at approx. 50%.
Î
Fasten the positioner to the NAMUR bracket, making sure that the
follower pin is in the slot of the follower plate. Make sure the lever
can move freely.
