• Assemble the lever (if not preassembled). The distance of

the driving pin from the axle should
be equal to the stroke. This results
in a swing angle of the lever of 60°.
The scale printed on the lever
is irrelevant.

• Fix the lever onto the axle of the SIDE

Control.

• Fix attachment bracket (1) to the SIDE

Control.

Alignment of the lever mechanism

The lever mechanism can be aligned properly only when the
device has been connected electrically and pneumatically.

• In the manual mode, move the actuator to half stroke

(corresponding to scale on actuator).

• Move the device vertically until the lever is horizontal.
• Fix the device finally to the actuator.

Attachment to a continuous valve with part-turn
actuator

• Select the M8 thread on the

SIDE

Control such that the

conical roller (5) on the lever of
the position sensor can move
freely in U-piece (2) on the
actuator over the entire stroke.

• Mount the U-piece on the drive

spindle of the actuator.

• Attach the SIDE

Control to the cast

frame or post yoke of the actuator
according to NAMUR procedure.

• To make electrical connection, open the cover of the

SIDE

Control by unscrewing the 2 screws.

Connection of a potential equalization conductor
(PE) to the electronics is not required.

If after starting the function

X.TUNE the message

X.ERR 5 appears in the LC display, the alignment of
the axle of the SIDE

Control to the axle of the

actuator is incorrect.

• Push adapter (1) onto the axle of the

SIDE

Control and fix it with 2

setscrews (2). One of the setscrews
should press onto the flat on the axle
(to prevent slip!). It must be assured
that the axle of the SIDE

Control can

move only in one of the ranges
shown below in the drawings.
Observe the flat on the axle!

• Determine the orientation of attachment of the SIDE

Control

(parallel to the actuator or rotated by 90°).

• Determine the basic position and direction of rotation of the

actuator.

• Place the SIDE

Control on the

bracket and fix it.

• Mount the SIDE

Control with the

bracket on the part-turn
actuator.
