FixIng the limit switch plates
4.4
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.
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.20-Part.A).
Release
•
the operator (see the
Par. Emergency manouvre
).
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.20-ref.1
), then fi x
it on the rack screwing the relevant dowels (
Fig.19
).
Move the gate to the required
•
OPEN
position (leaving
it clear of the mechanical stop by the required safety
margin). Place the second plate (
Fig.20-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.
