SLIDING GATES
3.4
FixIng the limit switch plates
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 plates and the
mechanical gate fully open and gate fully closed stops
(Fig.27).
• Unlock the operator (see the relevant Paragraph).
• Move the gate to the CLOSE position (1 or 2 cm from the
mechanical stop). Place the fi rst plate in such a way that it
engages the operator limit switch (Fig.28), then fasten it in
the slots in the rack using the grub screws (Fig.29).
• Move the gate to the required OPEN position (leaving it
clear of the mechanical stop by the required safety margin).
Place the second plate in such a way that it engages the
limit switch, then fasten it in the slots in the rack using the
relevant grub screws.
• Move the gate to an intermediate position (neither limit
switch plate must be engaged) and lock the actuator. Move
the gate a little in either direction until you hear the sound
of mechanical parts engaging.
