5.2 Lever and pin position

The positioner is adapted to the actuator and
to the rated travel by the lever on the back of
the positioner and the pin inserted into the
lever.
The travel tables on page 26 show the
maximum adjustment range at the position-
er. The travel that can be implemented at the
valve is additionally restricted by the selected
fail-safe position and the required compres-
sion of the actuator springs.
The positioner is equipped with the M lever
(pin position 35) as standard (see Fig. 5).
Note
The M lever is included in the scope of deliv-
ery.
S, L, XL levers are available as accessories
(see Table 4 on page 23). The XXL lever is
available on request.
If a pin position other than position 35 with
the standard M lever is required or an L or
XL lever size is required, proceed as follows
(see Fig. 6):
1. Fasten the follower pin (2) in the as-
signed lever hole (pin position as speci-
fied in the travel tables on page 26).
Only use the longer follower pin includ-
ed in the mounting kit.
2. Place the lever (1) on the shaft of the po-
sitioner and fasten it tight using the disk
spring (1.2) and nut (1.1).
