SLIDING GATES
FixIng the limit switch plates
4.3
The actuator has an electromechanical limit switch with a
spring rod. The limit switch is tripped by two metal plates that
must be fi tted on the rack in such a way as to engage the
limit switch rod when the gate is near the fully open and fully
closed positions. Fix the limit switch by means of the relevant
plates with adjusting slots, to be welded on the rack.
Warning
!
To avoid crushing risk, do not use the mechanical
gate stops as the gate stroke limits. Always leave the
safety margin required by current Safety Regulations
between the limit switch stops and the mechanical
stops (Fig.9-Part.A).
Release
•
the operator
(see Par. Emergency operations)
.
Move the gate to the
• CLOSE
position (5 cm from the
mechanical stop). Place the fi rst plate in such a way that
it engages the operator limit switch (
Fig.9-ref.1
), then fi x it
on the rack, screwing the relevant dowels (
Fig.8
).
Move the gate to the required
• OPEN
position (attention
to the safety distance from the mechanical end stop).
Place the second plate (
Fig.9-ref.2
) in such a way that it
engages the limit switch, then fi x it on the rack screwing
the relevant dowels.
Move the gate to an
•
intermediate position (neither limit
switch must be engaged) and re-lock the actuator. Move
the gate a little in either direction until you hear a coupling
click.
