MANUAL RELEASE
In the event of a power failure, use the manual release device to
move the gate. Remove the plastic cover over the lock, insert the
key and remove the small safety guard.
BIG12-18:
Turn the handle clockwise (fig. 19).
BIG30-40:
Using the hex wrench provided, rotate the release
assembly counter-clockwise at least one complete
turn (fig. 20B). To restore normal operation, simply
tighten the release assembly (1 fig. 20A) by screw-
ing it in until it reaches the mechanical stop.
LIMIT SWITCH
The gear motors in the BIG series have been designed to work
with an electromechanical limit switch featuring a single dual-effect
switch.
Cable connections:
1 = common
2 = blue (common)
3 = brown (close L.S. – N.C. contact)
4 = black (open L.S. – N.C. contact)
WARNINGS
The fitter is responsible for ensuring the system can be used cor-
rectly and functionally. He must also provide it with all the safety
devices and/or signals required to ensure it complies with current
law. Make sure that each single device is in perfect working order.
As regards vertical tubular gates, the system must be fitted with a
protective mesh covering the whole surface of the gate.
Put up easy-to-read signs informing people that the gate is pow-
ered.
It is forbidden to use the equipment for other purposes or in other
circumstances than those mentioned.
In particular:
1 do not touch the equipment with wet hands;
2 disconnect the power supply before opening the control box
and/or the gear motor;
3 do not pull the power cable to remove the power plug;
4 do not touch the motor unless you are sure it has cooled down;
5 only move the gate when it is completely visible;
6 do not approach the gate if this is moving: wait until it has
stopped;
7 do not allow children or animals to play near the gate;
8 do not allow children or unauthorised people to use the remote
control or other control devices;
9 carry out routine maintenance;
10 in the event of a fault, disconnect the power supply and only
move the gate if it is possible and safe to do so.
MAINTENANCE
Attention: only the maintenance man, who must be a specialised
technician, is allowed to operate the automatic system during
maintenance. The power supply should therefore be disconnected.
If the power supply must be left on for certain operations, each
control device should be checked or disabled (remote controls,
push button strips, etc.) except for the one used by the mainte-
nance man.
ROUTINE MAINTENANCE
Each of the following operations must be carried out when neces-
sary and always every 6 months.
Gate: check the general condition of the gate.
Automation system:
1 check the safety devices.
2 regularly grease the release device

EXTRAORDINARY MAINTENANCE OR BREAKAGE
If major work on electromechanical parts must be carried out, the
faulty part should be removed and repaired in the workshop by the
manufacturer's or other authorised technicians.
