Routine Maintenance - tau BIG Série Manuel D'emploi Et D'entretien

Fix the shoes as shown in fig. 16, one near either end of the rack. Move the leaf by hand and position the shoes so that they touch the micro-
switch lever just before the leaf hits the travel stops at both ends of the rail; then tighten the screws.
A single factor or combination of factors (thermal expansion, climate, frequency of use, etc.) may result in the position the
gate stops in changing over the course of the day, both when opening and when closing. Consequently, we cannot guarantee
that the gate will always stop in the same position.
6. ADJUSTING THE MECHANICAL CLUTCH
Before starting, make sure to disconnect the gear motor from the power supply.
BIG18:
Make a 1/2 or a whole turn at a time using the supplied wrench (fig. 17).
BIG30-40: After removing the lock nut (1 fig. 18A) and the stop dowel (2 fig. 18A), adjust the thrust force using the hex wrench provided
(3 fig. 18B) (rotate clockwise to increase the thrust force, rotate counter-clockwise to decrease it). After adjusting as needed,
reassemble the stop dowel (2 fig. 18D) until it reaches the mechanical stop, then fasten the lock nut (1 fig. 18D).
7. VERSION WITH CHAIN PINION: R30 / R40
The door can also be power-operated as shown in fig. 19. Pass the chain as shown in fig. Fig. 19 also shows the type of chain required (pitch
5/8" x 3/8").
8. ELECTRICAL CONNECTIONS
For electrical connection, please refer to the specific instructions for each electrical control panel. The following tips apply to all models.
Do not put the power cables in the same sheath as the motor cables. Always choose the shortest routes for the cable lines. Make sure the
equipment is well earthed. A general switch should be fitted to the system, out of reach of unauthorised people, allowing power to be discon-
nected from the gear motor for maintenance purposes or if the gear motor remains inactive for a long period.
9. 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.
BIG18: Turn the handle clockwise (fig. 20).
BIG30-40:
Using the hex wrench provided, rotate the release assembly counter-clockwise at least one complete turn (fig. 21B). To restore
normal operation, simply tighten the release assembly (1 fig. 21A) by screwing it in until it reaches the mechanical stop.
It is mandatory, at least once a year, to perform the unlocking test. Once the gate has been unlocked, if it is blocked or
particularly heavy to move manually, it is suggested to knock slightly with a hammer on the release screw (fig. 21C). This is
in order to detach the clutch plates.
10. 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)
11. WARNINGS
The fitter is responsible for ensuring the system can be used correctly 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 powered.
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.
12. 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 maintenance man.

ROUTINE MAINTENANCE

Each of the following operations must be carried out when necessary and always every 6 months.
3 = brown (close L.S. – N.C. contact)
4 = black (open L.S. – N.C. contact)
