Place the control unit (external versions) in the immedi-
ate vicinity of the motors.
Be careful not to run cables for auxiliary devices in-
side raceways housing other cables supplying power
to large loads or lights with electronic
In the event control pushbuttons or indicator lights are
installed inside homes or offices several metres from
the actual control unit, it is advisable to decouple the
signal by means of a relay in order to avoid induced
interference.
ADJUSTMENT OF THE ELECTRONIC/ELECTRIC CLUTCH
WARNING: Check that the impact force value measured at the
points foreseen by the EN 12445 standard is lower than that
indicated in the EN 12453 standard.
The adjustment on MASTER12Q is already preset during the pro-
gramming of the control unit and can in any case be set (see in-
structions K123M).
The adjustment of MASTER20QR and MASTER20QM can be
performed through the control unit, see instructions D705M.
The adjustment of MASTER20T can be performed through the
control unit, see instructions D703M.
ELECTRICAL CONNECTIONS
Note: the MASTER series has a microswitch that cuts-out the
motor when the casing is opened, A fig. 25 (the control unit
remains live).
Make sure that the gearmotor is disconnected from the power
supply before performing any operations.
To make the connections, remove the gearmotor casing, pass
the cables through the holes on the base plate (when used) and
through the lower section of the gearmotor. Then arrange the ca-
bles for the connection to the control unit terminal block that is
located in the electrical components support.
The distance between the control unit and the motor must not ex-
ceed 10 – 12 m.
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 MAS-
TER20T, and 0.5 mm ² for the control circuit.
Consult the related instructions booklet for the control unit con-
nections:
- K123M for MASTER12Q;
- D705M for MASTER20QR and MASTER20QM.
- D703M for MASTER20T;
Note: the thermal protection (for MASTER20T only) must be
wired in series to the common of the limit switch (terminal 19
of the D703M board).
12V BATTERY INSTALLATION
If one wishes to fit a battery to the MASTER12Q gearmotor in or-
der to guarantee power in the event of blackout, remove the casing
and fit the battery into its location; then connect the power supply
cables to the tongues.
MANUAL RELEASE
In the absence of the mains power supply, remove the lock cover,
insert the special key and turn it as indicated in fig. 21.
Then pull the lever outwards in order to manually manage the gate,
as shown in fig. 22.

LIMIT SWITCH
The MASTER series has been designed to operate with a micros-
MASTER20T
witch electromechanical limit switch device.

- brown (L.S. close - contact N.C.);
- blue (Common).
GENERAL WARNINGS
Integrate the gate safety in accordance with the present regula-
starters.
tions.
- 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 gearmo-
tor's maximum torque;
- An external switch should be fitted in compliance with the Eu-
ropean safety standards in order to turn off the power supply to
the gate for maintenance purposes;
- Make sure that all devices are efficient and in working order;
- Post clearly legible signs informing that the gate is motorised.
USE
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 MASTER20QR, MASTER20QM
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 com-
mand input;
The gate can be manually controlled by means of a manual re-
lease 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 sup-
plied with power, therefore the necessary precautions must be im-
plemented while in use. Therefore it is advised:
• 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 malfunc-
tion. 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.
