wires on the control unit terminal block.

In order to connect the magnetic limit switches to other control units, wiring must be as follows:

- black (L.S. open - contact N.C.);

- brown (L.S. close - contact N.C.);

- blue (Common).

Operators MASTER18QR and MASTER-R must be provided with mechanical stops on the gate both in the opening manoeuvre and espe

cially in the closing one, since they are equipped with the encoder and the stroke is set up through the operation of the control board

K126MA (see the user manual of the control board).

9. GENERAL WARNINGS

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 fitted 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 efficient and in working order;

- Post clearly legible signs informing that the gate is motorised.

10. USE

The MASTER series gearmotors have been designed for the movement of horizontally sliding gates weighing up to 1200 Kg for

MASTER-R

, 1800

Kg for

MASTER18QR

, 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 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 func

tioning of the

MASTER18QR

and

MASTER-R

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:

• 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 au

thorised 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.

11. MAINTENANCE

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..);
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.
