Assembly
Variant 3 of the positioner is mounted on a DIN rail.
To mount the external feedback/positional transducer, do the following (refer to Fig. 17):
a) Make sure that an O-ring has been inserted into the valve actuator (top). Insert ring "6" if necessary.
b) Unscrew fastening screw "3".
c) Place the plastic ring "4" on the top of the actuator "5" (sizes 100 and 125 only) then screw the
external feedback/positional transducer (fig. 14) on it.
d) Tighten fastening screw "3".
e) Unscrew housing "11" of the external feedback/positional transducer.
f) The cable of the path-measuring system must be placed behind the latter so that it does not hinder
the displacement of the spindel of the feedback/positional transducer.
3.1.3 Fitting the positioner variant 3 for a continuous valve with piston drive
Arrangement
A continuous valve with piston drive can be used with variant 2 of the positioner with the external
feedback/positional transducer (Fig. 14) which is set on the valve and screwed to it (Fig. 15). The valve
position is transmitted directly via the spring-mounted rod of the path-measuring system (the linear
potentiometer).
