Use cables with a minimum section of 2.5 mm ² for the power
circuit of the MASTER12Q and 1.5 mm² for the MASTER20Q and
MASTER20T, and 0.5 mm ² for the control circuit.
Consult the related instructions booklet for the control unit
connections:
- K123M for MASTER12Q;
- D704M for MASTER20Q.
- D703M for MASTER20T;
N.B. The thermal protection (for MASTER20T only) must be
wired in series to the common of the limit switch (ter-
minal 19 of the D703M board).
If one wishes to fi t a battery to the MASTER12Q gearmotor in
order to guarantee power in the event of blackout, remove the
casing and fi t the battery into its location; then connect the power
supply cables to the tongues.
In the absence of the mains power supply, remove the lock cover,
insert the special key and turn it as indicated in fi g. 21.
Then pull the lever outwards in order to manually manage the gate,
as shown in fi g. 22.
The MASTER series has been designed to operate with a
microswitch electromechanical limit switch device.
The cables are connected as indicated in fi g. 25:
1= grey (common);
2= grey (common);
3= orange (L.S. close - contact N.C.);
4= red (L.S. open - contact N.C.);
5= grey (common).
If the movement continues when the gears rotate in a clock-wise
direction and the spring moves as shown in fi g. 26, invert the red
and orange wires on the control unit terminal block.
Integrate the gate safety in accordance with the present
regulations.
- Choose short paths for the cables and keep the power and
control cables separated;
- Make sure that the equipment is correctly grounded;
- Abide by the present regulations for the setup of the gearmotor's
maximum torque;
- An external switch should be fi tted in compliance with the
European safety standards in order to turn off the power supply
to the gate for maintenance purposes;
- Make sure that all devices are effi cient and in working order;
- Post clearly legible signs informing that the gate is motorised.
The MASTER series gearmotors have been designed for the
movement of horizontally sliding gates weighing up to 1200 Kg for
MASTER12Q, and 2000 Kg for MASTER20Q and MASTER20T.
Use of the equipment for aims or circumstances different
from those stipulated is prohibited.
The following functions can be selected by means of the control
unit:
automatic: the gate is opened and closed following a command
input;
semiautomatic: the gate is opened or closed following a command
input;
The gate can be manually controlled by means of a manual release
in the event of a power failure. In the event of a power failure,
normal functioning of the MASTER12Q model is guaranteed by
means of a buffer battery.
It must be remembered that this has an automatic device and
supplied with power, therefore the necessary precautions must be
implemented while in use. Therefore it is advised:

GENERAL WARNINGS
• not to touch the equipment with wet hands and/or wet or bare
feet;
• to disconnect the power before opening the control box and/or
gearmotor;
• not to pull the power supply cable to remove the plug from the
socket;
• not to touch the motor unless you are sure that it has cooled;
• to start the manoeuvre of the gate only when it is fully visible;
• to stay outside the manoeuvring range of the gate when in
movement: wait until it has stopped moving;
• not to let children or animals play close to the gate;
• not to let children, or those unable, use the remote control or
other activating devices;
• to perform periodic maintenance;
• to disconnect the power supply and manually open and
close the gate only when possible and safe in the event of
malfunction. Call an authorised technician and do not try to
resolve the problem yourself.
NOTE: THE USE OF A WATER-JET CLEANER OR SIMILAR
IS PROHIBITED FOR THE CLEANING OF THE
AUTOMATION SYSTEM. JETS OF WATER MUST
NOT BE DIRECTED ONTO THE AUTOMATION
SYSTEM.
The MASTER series gearmotors require very little maintenance.
Nevertheless, their correct functioning also depends on the state of
the gate. Therefore here is a short description of the operations to
perform in order that the gate remains in good working order.
Warning: no persons, except the specialised maintenance
technician, must activate the automatic gate during the
maintenance operations.
Therefore the power supply should ideally be disconnected
thereby avoiding possible electric shocks. If on the other hand
it is necessary that the power supply is connected for the said
inspection, each control device (remote controls, push button
panels, etc) should be checked and disabled except for those
being used by the maintenance technician.
Routine maintenance
Each of the following operations must be performed when
necessary or in any case every 6 months for domestic use (approx.
3000 working cycles) and every 2 months for intensive use, e.g.
apartment blocks (again, every 3000 working cycles).
Gate
- Lubricate (with oiler) the wheels of the gate;
- Check that the rack is clean and correctly connected;
Automation system
- Check that the safety devices are working correctly (photocells,
pneumatic edges, torque limiting device, etc..);
USE
Extraordinary maintenance
If more complicated tasks need to be performed on the
mechanisms, the gearmotor should ideally be removed in order
for the work to be carried out by experienced technicians in the
manufacturers or an authorised workshop.
The aerial noise produced by the gearmotor under normal use is
constant and does not exceed 70 dB.
The materials must be disposed of in accordance with the current
laws and regulations.
No dangers or risks are present in the event of scrapping of the
automation system.
If materials are to be recycled, they should ideally be divided
based on their type (electrical parts – copper – aluminium – plastic
– etc...).
