3.6 Assembling the limit-switch brackets
3.6.1 PVC brackets for Toothed Rack B117
a)
IIdentify closing and opening brackets according
to the motor position against the gate (Fig. 13).
b)
Manually close the gate up to 3cm before the
closing mechanical stop.
c)
Place the closing bracket on the rack and slide it
until the limit-switch is activated (Fig. 14).
d)
Mark the bracket position onto the rack, slightly
open the gate and fix the bracket to the rack.
e)
Manually open the gate (gate end aligned to the
pillar edge).
f)
Place the opening bracket on the rack and slide
it until the limit-switch is activated (Fig. 15).
g)
Mark the bracket position onto the rack, slightly
close the gate and fix the bracket to the rack.
3.6.2 Universal steel brackets
a)
Identify closing and opening bracket according to
the motor position against the gate (Fig. 16).
b)
Manually close the gate up to 3cm before the
closing mechanical stop.
c)
Place the two screw fixings loosely on the closing
limit bracket.
d)
Place the closing bracket on the rack and slide it
until the limit-switch is activated (Fig. 14).
e)
Screw the two screws tightly to anchor the bracket
onto the rack.
f)
Manually open the gate (gate end aligned with the
edge of the pillar).
g)
Place the two screws fixings loosely on the opening
limit bracket.
h)
lace the opening bracket on the rack and slide it
until the limit-switch is activated (Fig. 15).
i)
Screw the two screws tightly to anchor the bracket
onto the rack.
Once the assembling of the limit brackets to rack is completed, open and close the gate manually to check that the
brackets always activate the limit-switch system before the gate reach its mechanical stops. This checking is important to
preserve the correct working of the automation and continued good mechanical condition of the gate.
