Installation on a valve controller
The limit switch may be installed on an existing valve con-
troller.
ND9100
If the valve controller is already mounted on an actu-
ator/valve assembly, operate the actuator into the
closed or open position.
Remove the cover (100), the pointer (109), the LUI
(223), the prestage cover (43) and electronics cover
(39).
Turn the shaft (311) onto the shaft (11). Fasten the
screw (312) using a locking agent such as Loctite.
Unfasten the screws (314) in the cam discs (313).
Mount the electronics cover (39) and the housing
(300) on the valve controller.
ND9100/K00:
Turn the cam discs (313) to avoid con-
tact with the micro switches, if required.
Mount the LUI (223) on the bed (306).
Mount the pointer (109) on the shaft (311). Adjust
the limit switch according to 9.4.

Mount the electronics cover (39) and the limit switch
housing (300) on the valve controller. Lock the hous-
ing in place with screw (326). Install the base plate
(324) with the limit switches and connector block
into the limit switch housing. Fasten the base plate
with screws (325), 3 pcs.
Install the cam discs (313) and bushings (346) to the
shaft.
Mount the LUI (223) on the holder (306).
Replace the plastic plugs with metal ones in conduit
entries which will not be used.
Mount the pointer (109) on the shaft (311). Adjust
the limit switch according to 9.4.
