NSTALLATION
Assembly
Mount U-piece (2) using clamping pieces (3), hex screws (17) and lock washers (16) on actuator
spindle.
Select the short lever (Table Add-on kit to linear actuator, Serial no. 6a) or long lever (Table Add-on kit
to linear actuator, Serial no. 6b), depending on the actuator stroke.
Assemble the lever (if not preassembled).
The distance of the driving pin from the axle should be
equal to the actuator stroke. This results in a swing angle of
the lever of 60°. This assures that the position sensor works
with good resolution. The scale printed on the lever is irrele-
vant.
Push the lever onto the axle of the SIDE Control and screw it tight.
Fix attachment bracket (1) with hex screws (9), lock washers (10) and washers (11) to the rear side
of the SIDE Control.
Which M8 thread on the SIDE Control is
chosen depends on the size of the actuator
To determine the correct position, hold the
SIDE Control with bracket against the
actuator. The conical roller (5) on the lever
of the position sensor must be able to move
freely in U-piece (2) on the actuator over
the entire stroke. At 50% stroke, the lever
position should be roughly horizontal (see
under
Alignment of the lever mechanism).
