ENGLISH ENGLISH

These instructions apply to the following models:

746 EMC Z20 - 746 EMC CAT - 746 EMC RF

The FAAC model 746 automation for sliding gates is an electromechanical operator which transmits movement to the gate leaf by means of a rack and pinion or drive chain coupled in appropriate manner to the sliding gate. The irreversible system ensures that the gate is mechanically locked when the motor is not in operation and therefore it is not necessary to install a lock. The gear motor is equipped with an adjustable mechanical clutch which, in conjunction with an electronic sensor, affords the necessary adjustable anti-crushing safety and guarantees that the gate motion is either stopped or reversed when an obstacle is encountered. A release device allows the gate to be operated manually in the event of a power failure or malfunction. The electronic control unit is supplied with the gear motor and is housed inside the operator.

The 746 automation has been designed and built for vehicle access control. Do not use for any other purpose.

1. DESCRIPTION AND TECHNICAL CHARACTERISTICS

1.1. MAXIMUM UTILISATION CURVE

The curve allows the maximum working time (T) to be obtained as a function of duty cycle (F). E.g.: the 746 operators can work continuously at a duty cycle of 30%.

To ensure good operation, keep to the field of operation lying below the curve. Important: The curve refers to a temperature of 24°C. Exposure to direct sunlight can result in a reduction in duty cycle to as low as 20%.

Calculating duty cycle

The duty cycle is the percentage of effective working time (opening + closing) with respect to the total cycle time (opening + closing + pause times). It is calculated using the following formula:

Ta + Tc

%F =

X 100

Ta + Tc + Tp + Ti

where: Ta = opening time Tc = closing time Tp = pause time Ti =

interval between one complete cycle and the next.

4. INSTALLING THE AUTOMATION

4.1. PRELIMINARY CHECKS

For safe, correct operation of the automation, make sure that the following requirements are met:

• The gate’s structure must be suitable for automation. Take

special care to ensure that the wheels are large enough to support the full weight of the gate, that a top runner is installed and that physical limit stops are fitted to prevent the gate from coming off the runner.

• The characteristics of the ground must ensure sufficient

support for the foundation plinth.

• There must be no pipes or electrical cables in the area to be

dug for installing the foundation plinth.

• If the gear motor is located in a vehicle transit area, it is

advisable to provide protection against accidental collisions.

• Check that there is an efficient ground point for the gear

motor connection.

4.2. INSTALLING THE BASE PLATE

1) Assemble the base plate as shown in Fig.4.

2) The base plate must be positioned as shown in Fig. 5 (right-

handed closure) or Fig. 6 (left-handed closure) to ensure that the pinion and rack mesh correctly.

3) Prepare a foundation plinth as shown in Fig. 7 and install the

base plate providing one or more conduits for electrical cables. Use a level to check that the plate is perfectly horizontal and wait for the cement to set.

4) Lay the electrical cables for connection to the accessories

and the electricity supply as shown in Fig. 3. For ease of

connection, ensure that the cables protrude by about 40 cm from the hole in the base plate (Figs. 5-6 ref.1).

5.3. DIPSWITCH SETTINGS

To program the operation of the automation, set the dipswitches as shown in the diagram above.

Ü Press the RESET button after all programming operations.

(1) With the pre-flashing selected, movement starts after 5 seconds. (2) If the impulse is sent during pre-flashing, the timer is reset to zero.

5.4. FAULT CONDITIONS

The following conditions effect normal operation of the automation:

a microprocessor error b intervention of the electronic safety timer (interruption of

operation after continuous working time exceeds 255 seconds).

c disconnection of the limit switch cable connector

• Conditions a and b have the sole effect of causing the automation to stop.

• Condition c causes an alarm condition inhibiting all operation:

normal operation is only resumed after the cause of the alarm has been eliminated and the RESET button has been pressed (or the power supply has been

momentarily interrupted). To signal this condition, the warning light must be connected: an alarm condition is signalled by rapid flashing (0.25 sec) of the warning light.

5.5. POSITIONING THE TRAVEL STOP PLATE

The 746 operator is fitted with an inductive proximity limit switch (Fig.1 - ref.3). When the latter detects the passage of a plate fastened to the top of the rack, it stops the movement of the gate. To position the two travel stop plates correctly, proceed as follows:

1) Connect the limit switch connector to the 746MPS control

unit in accordance with the direction of gate closure (paragraph 5.2.3. and Figs. 28/29).

2) Assemble the limit switch, positioning the stop plate cen-

trally relative to the threaded studs of the bracket (Fig.32).

3) Switch on the power supply.

4) Move the gate by hand towards it closed position, stop-

ping approximately 2 cm from the physical travel stop.

5) Set brake-adjusting trimmer TR1 approximately to its cen-

tral position (Fig.23 - ref.TR1).

TABLE 5 LOGIC A1 (AUTOMATIC)

Operating logics

There are four operating logics available:

A1= Automatic A2 =Automatic Plus E1 = Semi-automatic E2 =Semi-automatic Plus

Operation of the different logics is described in tables 5-6-7-8.

6) Slide the travel stop plate on the rack in the opening direction. When the LED of the opening travel limit switch (FCA) in the 746 electronic control unit (Fig. 23) goes out, advance the travel stop plate by approximately 45 mm, and fix it to the rack by tightening the screws.

7) Move the gate by hand towards its closed position, stopping approximately 2 cm from the physical travel stop.

8) Slide the travel stop plate on the rack in the closing direction. When the LED of the closing travel end limit switch (FCC) in the 746 electronic control unit goes out (Fig. 23), advance the travel stop plate by approximately 45 mm, and fix it to the rack by tightening the screws.

9) Re-lock the system (see paragraph 8).

10) Run a complete cycle of the gate, to check whether the limit switch trips correctly. To adjust the limit switch positions, operate brake trimmer TR1: when the trimmer is rotated clockwise, the braking space is decreased; when the trimmer is rotated counterclockwise, the braking space is increased.

Notes on positioning the travel stop plates

• The distance between the limit switch and the travel stop

plate must be < 5mm (Fig.11).

• When nylon rack is used, the limit switch plate will be

mounted without the support. Fix the plate directly on the rack with the self-tapering screws. Adjust the limit as mentioned above.

• To avoid damaging the operator and/or interruptions to

service, leave a distance of at least 2 cm from physical travel stops of the gate.

5.6. TORQUE ADJUSTMENT

The 746 automation system is equipped with an anti-crushing system comprising an electronic sensor and a mechanical clutch which (according to the selected operation) either stops or reverses gate motion when the gate encounters an obstacle. When the obstacle is removed, a new command impulse must be given before the gate resumes the opening or closing movement. The torque limiting clutch must be set in compliance with current standards. To adjust the threshold of the anti-crushing system, proceed as follows:

1) Switch off the power supply.

2) Hold the driving shaft in position by means of the lever supplied, and adjust the clutch adjusting screw, as shown in Fig. 33. To increase torque, turn the screw clockwise. To decrease torque, turn the screw counterclockwise.

Ü The operator is supplied with the clutch set to maximum

torque. It will therefore be necessary to turn the adjuster

screw counterclockwise to obtain the optimum adjustment.

3) Switch on the power supply and check whether the anticrushing system operates correctly.

Ü When tripped, the anti-crushing system either stops the opening movement or reverses the closing movement.

6. TESTING THE AUTOMATION

When installation is complete, press fit the covers over the operator fixing bars and fix the top cover using the screws and bushes supplied (Fig. 34).

8. RETURN TO NORMAL OPERATION

To prevent accidental operation of the gate during this procedure, turn off the electricity supply to the system before relocking the operator.

1) Close the release lever.

2) Turn the key anticlockwise.

3) Remove the key and close the lock cover.

4) Move the gate until the release device engages.

9. SPECIAL APPLICATIONS

There are no special applications.

10. MAINTENANCE

When performing maintenance, always check that the anticrushing clutch is correctly adjusted and that the safety devices operate correctly.

10.1. TOPPING UP WITH OIL

Check the quantity of oil in the operator periodically. For medium-low duty cycles an annual check is sufficient; for more intensive use, check every 6 months. To access the oil reservoir, remove the oil filler cap (Fig.1 rif.8). The oil level should be up to the copper windings of the electric motor (Fig. 38). To top up, pour in oil to the correct level. Use exclusively FAAC XD 220 oil.

11. REPAIRS

GENERAL SAFETY INSTRUCTIONS

The 746 automation, when installed and used correctly, affords a high level of safety. However, some simple rules should be followed to avoid accidents:

- Do not stand in the vicinity of the automation or allow anyone

else, especially children, to do so, and do not place objects in the vicinity of the automation. This is particularly important during operation.

- Keep remote controls or any other control devices out of the

reach of children to prevent them from accidentally operating the automation.

- Do not allow children to play with the automation.

- Do not deliberately obstruct the movement of the gate.

- Make sure that branches or bushes do not interfere with the

movement of the gate.

- Ensure that the signalling lights are efficient and clearly

visible.

- Do not attempt to move the gate manually without first

releasing it.

- In the event of a malfunction, release the gate to allow

access and call a qualified technician for service.

- After setting manual operation, disconnect the electricity

supply from the system before returning to normal operation.

- Do not make any modifications to components of the auto-

mation system.

- Do not attempt to perform any repair work or tamper with the

automation. Call FAAC qualified personnel for repairs.

- At least once every six months have the automation, the

safety devices and the earth connection checked by a qualified technician.

DESCRIPTION

The FAAC 746 automation is ideal for controlling vehicle access areas with medium transit frequencies. The FAAC model 746 automation for sliding gates are electromechanical operators which transmit movement to the leaf by means of a pinion with rack or chain coupled in appropriate manner to the sliding gate. The operation of the sliding gate is controlled by an electronic control unit housed inside the operator. When the gate is closed, on receipt of an opening impulse from a remote control or other suitable control device, the control unit will start the motor to move the gate to the open position. If automatic operation has been selected, sending an impulse causes the gate to reclose on its own after the selected pause time. If semiautomatic operation has been selected, a second impulse must be sent to reclose the gate. An opening impulse send while the gate is reclosing causes it to change direction of movement. A stop command (if available) stops movement at any time. For detailed information on operation of the sliding gate in the various operating modes, contact the installation technician. The automations have safety devices (photocells) which prevent the gate from reclosing when an obstacle lies within the area they are protecting. The system ensures mechanical locking when the motor is not in operation, so it is not necessary to install a lock. For this reason the release system must be operated before the gate can be opened manually. The gear motor has a mechanical clutch which, in conjunction with an electronic sensor, affords the necessary anti-crushing safety, reversing a closing movement or stopping an opening movement.

An inductive sensor detects the passage of the metal stop plates fixed to the rack in correspondence with the travel limit positions. The electronic control unit is incorporated in the gear motor. A convenient manual release device allows the gate to be operated in the event of a power failure or malfunction. The light flashes while the gate is moving.

MANUAL OPERATION

If the gate has to be operated manually due to a power failure or malfunction of the automation, use the release device as follows.

1) Open the lock cover plate and insert the key supplied in the lock (Fig.1).

2) Turn the key clockwise and pull the release lever as shown in Fig. 2.

3) Open or close the gate manually.

RETURN TO NORMAL OPERATION

To prevent accidental operation of the gate during this procedure, turn off the electricity supply to the system before relocking the operator.

1) Reclose the release lever.

2) Turn the key anti-clockwise.

3) Remove the key and close lock cover plate.

4) Move the gate until the release device engages.
