3.3.3.2 Mounting instructions of limit switch
for “retracted position”
If the limit switch for “retracted position” has been removed,
please follow these instructions to mount it again correctly:
Limit switch for “retracted position”
Roller screw
nut (back side)
It’s this surface that’s detected by
the limit switch. In that view and in
this position, L
t
equals to L
t0
.
1. Move cylinder so that L
t
= L
t0
(±0,5 mm).
NOTE: To know the definition of L
t
and L
t0
, please look at
paragraph ⮑ 3.2.2 Visual cylinder position – L
t0
and L
t
definition, page 14.
2. Screw in the limit switch with care by hand into the dedi-
cated threaded hole until it touches the roller screw nut
(see cross-section view above). Then, unscrew the limit
switch to create a gap between it and the rollerscrew nut.
Stop unscrewing just before the limit switch stops
detecting.
3. Fix the limit switch in this position by tightening the coun-
ter-nut (tightening torque: 7 Nm).
4. In this position, check that the limit switch detects the
roller screw nut.
5. Move the cylinder so that L
t
= L
t
+ 3 mm (±0,5 mm). In
this position, please check that nothing is detected by
the limit switch.
