Aprimatic ONDA 424 Instrucciones Para La Instalación página 22

Installation
If the fi t is imperfect and it is impossible to maintain the
correct pitch, then you need to adjust them.
• Proceed as given in the previous points.
Warning
To prevent gate from weighing on the operator pinion,
the whole rack must be raised by 1.5 mm using the row
of slots for the different rack components; only after
this can the fi xing screws be fully tightened.
5.3 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.25).
• Unlock the operator (see Par. 8.1).
• Move the gate to the CLOSED 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.26), then
fasten it in the slots in the rack using the grub screws
(Fig.27) (further informations at Par.7.5).
• 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.
