AU T OMATION 844 MC-R & 844 MPSR

These instructions apply to the following models:

844 MC-R

The FAAC model 844MC-R automation for sliding gates is an electromechanical operator which transmits movement to the gate leaf by means of a rack and pinion coupled in an

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

interval between one complete cycle and the next.

Ti = appropriate manner to the sliding gate. The reversible system allows the gate to be moved manually when the motor is not in operation. An electric lock must therefore be installed to ensure that the gate cannot move when closed. The gear motor is equipped with an adjustable mechanical clutch which affords the necessary anti-crushing safety. A convenient manual release device allows the gate to be operated in the event of mechanical problems with the gear motor. The electronic control unit may be housed inside the operator or in a separate box.

The automation 844MC-R has been designed and built for vehicle access control. Do not use for any other purpose.

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 844 MC-R 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%.

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:

%F =

i Adjusting screw for anti-crushing clutch j Bore for access to oil filler cap k Cover lock operated with triangular key l Operator ground connection m Bores for passage of connection cables n Release lever o Fixing bar cover

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 stops are fitted to prevent the gate from coming off the runner.

• Make sure that the bottom runner is perfectly horizontal. If it slopes, the fact that the gear motor is reversible may allow the gate to move on its own.

• 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 the gear motor has an efficient earth 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 (righthanded closure (right-handed closure) or Fig. 6 (left-handed

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 (indicated by the fact that both LEDs FCA and FCC are off) prevents the card from operating: normal operation is only resumed after the cause of the

Page 10

ENGLISH

alarm has been eliminated and the RESET button has been pressed (or the power supply has been momentarily interrupted).

5.6. POSITIONING THE TRAVEL STOP PLATE

The 844 MC-R 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 844MPSR control unit in accordance with the direction of gate closure (paragraph 5.2.3. and Figs. 24/25).

2) Assemble the limit switch, positioning the stop plate centrally relative to the threaded studs of the bracket (Fig.31).

3) Switch on the power supply.

4) Move the gate by hand towards it closed position, stopping approximately 2 cm from the physical stop of the gate.

5) Set brake-adjusting trimmer TR1 approximately to its central position (Fig. 19 - ref. TR1).

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 844 MPSR electronic control unit (Fig. 28) goes out, advance the travel stop plate by approximately 45 mm, and fix it to the rack by tightening the screws.

5.7. TORQUE ADJUSTMENT

The 844 MC-R automation system is equipped with an anticrushing mechanical clutch which stops the opening/closing movement when the gate encounters an obstacle. When the obstacle is removed, the gate resumes its movement until the relevant limit switch trips or the safety time (TIME OUT) is exceeded. This torque limiter 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) Remove the cover of the relevant bore (Fig. 1- ref. 9), and unscrew the cap of the clutch adjusting screw (Fig. 32).

3) Keep the driving shaft in position by means of the supplied lever, and adjust the clutch as shown in Fig. 33. To increase torque, turn the screw clockwise. To decrease torque, turn the screw counterclockwise. the operator is supplied with the clutch set to maximum

torque. Initially, the working torque of the system must be decreased.

4) Switch on the power supply and check whether the anticrushing system trips correctly.

Fig. 31

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

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 844 MPSR electronic control unit goes out (Fig.28), 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 5).

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).

• To avoid damaging the operator and/or interruptions to

service, leave a distance of at least 2 cm

from the physical

stops of the gate.

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 ref.10). 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

For repairs contact an authorised FAAC Repair Centre.

USER’S GUIDE

844 MC-R AUTOMATION

Read the instructions carefully before using the product and keep them for future reference.

GENERAL SAFETY RULES

The 844 MC-R 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.

- If you have to use the release device to set manual opera-

tion, disconnect the electrical power supply.

- 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.

ENGLISH

The electronic control unit can be incorporated into the gear motor or installed separately. 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 opened manually due to a power failure or a malfunction of the automation, the electric lock must be released. If this is not sufficient (serious mechanical malfunction of the gear motor), the following operations must be performed on the release device.

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.

DESCRIPTION

The FAAC 844 MC-R automation is ideal for controlling vehicle access areas with medium-high transit frequencies. The FAAC model 844 MC-R 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 sent 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 allows the gate to be moved manually when the motor is not running, so an electric lock must be installed to keep the gate locked when closed. In the event of a malfunction or power failure, the gate can be opened only by releasing the electric lock. The gear motor has a mechanical clutch which affords the necessary anti-crushing safety.
