The curve makes it possible to establish maximum work time (T) according to use frequency (F). With reference to IEC 34-1 Stan

dard, the 740-741 gearmotor with an S3 duty, can operate at a use frequency of 30-40%. To ensure efficient operation, it is necessary to operate in the work range below the curve.

Important: The curve is obtained

at a temperature of 20°C. Exposure to the direct sun rays can reduce use frequency down to 20%.

Calculation of use frequency

Use frequency is the percentage of effective work time (opening + closing) compared to total time of cycle (opening + closing + pause times). Calculation formula: Ta + Tc % F = X 100 Ta + Tc + Tp + Ti where: Ta = opening time Tc = closing time Tp = pause time Ti = time of interval between two complete cycles

5.4. Assembling the rack

5.4.1. Steel rack to weld (Fig. 11)

1) Fit the three threaded pawls on the rack element, positioning them at the bottom of the slot. In this way, the slot play will enable any future adjustments to be made.

2) Manually take the leaf into its closing position.

3) Lay the first section of rack level on the pinion and weld the threaded pawl on the gate as shown in Fig. 13.

4) Move the gate manually, checking if the rack is resting on the

Fig.11

pinion, and weld the second and third pawl.

5) Position another rack element end to end with the previous one, using a section of rack (as shown in Fig. 14) to synchronise the teeth of the two elements.

6) Move the gate manually and weld the three threaded pawls, thus proceeding until the gate is fully covered.

5.4.2. Steel rack to screw

(Fig. 12)

1) Manually take the leaf into its closing position.

2) Lay the first section of rack level on the pinion and place the spacer between the rack and the gate, positioning it at the bottom

of the slot.

3) Mark the drilling point on the gate. Drill a Ø 6,5 mm hole and thread with an M8 male tap. Screw the bolt.

4) Move the gate manually, checking if the rack is resting on the pinion, and repeat the operations at point 3.

5) Position another rack element end to end with the previous one, using a section of rack (as shown in figure 14) to synchronise the teeth of the two elements.

6) Move the gate manually and carry out the securing operations as for the first element, thus proceeding until the gate is fully covered.

Notes on rack installation

• Make sure that, during the gate travel, all the rack elements do not exit the pinion.

• Do not, on any account, weld the rack elements either to the spacers or to each other.

• When the rack has been installed, to ensure it meshes correctly with the pinion, it is advisable to lower the gearmotor position by about 1.5 mm (Fig.15).

Values are expressed in mm

Fig.15

• Manually check if the gate correctly reaches the mechanical limit stops maintaining the pinion and rack coupled and make sure there is no friction during gate travel.

• Do not use grease or other lubricants between rack and pinion.

6. START-UP

6.1. Control board connection

Before attempting any work on th e board (connections, programming, maintenance), always turn off power.

Follow points 10, 11, 12, 13 and14 of the GENERAL SAFETY OBLIGATIONS. Following the instructions in Fig. 3, route the cables through the raceways and make the necessary electric connections to the selected accessories. Always separate power cables from control and safety cables

Fig.16

(push-button, receiver, photocells, etc.). To avoid any electric noise whatever, use separate sheaths.

6.1.1. Earthing

Connect the earth cables as shown in Fig.16 ref.A.

6.1.2. Electronic control unit

In the gearmotors, the electronic control unit is fitted to an adjustable support (Fig. 16 ref. 1) with transparent lid (Fig. 16 ref. 3). The board programming push buttons (Fig. 16 ref. 4) have been located on the lid. This allow the board to be programmed without removing the lid. For correct connection of the control unit, follow indications the specific instructions:

6.2. Positioning the limit switches

Important : For correct positioning of the limit switch magnets,

the control unit must be installed and correctly connected to all control and safety accessories.

The operator is fitted with a magnetic limit switch which commands the gate to stop at the moment when the magnet, fixed in the upper part of the rack, activates the sensor. The magnets supplied with the operator are suitably polarised and activate only one sensor contact, the closure contact or the opening contact.

Important: For correct functioning of the operator, the magnet with the circle must be positioned to the left of the motor and, vice versa, the magnet with the square must be positioned to the right of the motor (SEE FIGURE 18)

Fig.13

Fig.14

Page 6

Fig.17

Once installation of the operator has been completed, make a careful functional check of all accessories and safety devices connected. Move the board support back to its original position. Position the protective casings (Fig.19 ref.1), tighten the two side screws supplied (Fig.19 ref.2) and insert, under pressure, the supporting side pieces (Fig.19 ref. 3). Apply the adhesive, warning of danger, to the upper part of the casing (Fig.20). Give the Client the “User Guide” and demonstrate the correct operation and use of the gearmotor, highlighting the potentially dangerous zones of the automated system.

8. MANUAL OPERATION

Attention: Switch off the power supply to the system, to avoid any

possibility of an accidental impulse activating the gate during the release procedure.

To release the gearmotor, proceed as follows

1) Insert the appropriate key supplied and turn it clockwise as indicated in Fig.21 refs.1 and 2.

2) Turn the release system clockwise until the mechanical stop is reached Fig.21 ref.3.

3) Open or close the gate manually.

9. RESTORING NORMAL OPERATION

1) Assemble the two magnets as indicated in figure 18.

Fig.18

2) Prepare the operator for manual operation, as indicated in paragraph 8, then power up the system.

3) Manually move the gate into the open position, leaving 40 mm from the travel limit mechanical stop

4) Slide the magnet closest to the operator along the rack, in the direction of the motor. As soon as the LED for the limit switch on the board switches off, move the magnet forward by another 10 mm and fix it with the appropriate screws.

5) Proceed in a similar way for the other magnet.

6) Move the gate approximately half way through its run and re-lock the system (see paragraph 9).

Important : Before sending an impulse, ensure that the gate cannot move manually.

7) Perform a complete gate cycle to check correct operation of the limit switches.

Important : To avoid damage to the operator and/or interruptions in the operation of the automated system, approximately 40 mm must remain from the travel limit mechanical stops Check that at the end of the operation, both at opening and closure, the LED of the respective limit switch remains activated (LED off)

8) Make the appropriate changes to the position of the limit switch magnets.

7. AUTOMATED SYSTEM TEST

Fig.21

AUTOMATED SYSTEM 740-741

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

GENERAL SAFETY RULES

If installed and used correctly, the 740-741 automated system will ensure a high degree of safety. Some simple rules regarding behaviour will avoid any accidental trouble:

• Do not stand near the automated system and do not allow children and other people or things to stand there, especially while it is operating.

• Keep radiocontrols or any other pulse generator well away from children to prevent the automated system from being activated involuntarily.

• Do not allow children to play with the automated system.

• Do not willingly obstruct gate movement.

• Prevent any branches or shrubs from interfering with gate movement.

• Keep light signalling systems efficient and clearly visible.

• Do not attempt to activate the gate by hand unless you have released it.

• In the event of malfunctions, release the gate to allow access and wait for qualified technical personnel to do the necessary work.

• After enabling manual operation, switch off the power supply to the system before restoring normal operation.

• Do not make any alterations to the components of the automated system.

• Do not attempt any kind of repair of direct action whatsoever and contact qualified personnel only.

• Call in qualified personnel at least every 6 months to check the efficiency of the automated system, safety devices and earth connection.

DESCRIPTION

The 740-741 automated system is ideal for controlling vehicle access areas of medium transit frequency. The 740-741 automated system for sliding gates is an electro-mechanical operator transmitting motion to the sliding gate via a rack pinion or chain appropriately coupled to the gate. Operation of the sliding gate is controlled by an electronic control unit housed inside the operator or in a hermetically sealed outdoor enclosure. When, with the gate closed, the unit receives an opening command by radiocontrol or from another suitable device, it activates the motor until the opening position is reached. If automatic operation was set, the gate re-closes automatically after the selected pause time has elapsed. If the semi-automatic operation was set, a second pulse must be sent to close the gate again. An opening pulse during re-closing, always causes movement to be reversed. A stop pulse (if provided) always stops movement. The light signalling indicates that the gate is currently moving. For details on sliding gate behaviour in different function logics, consult the installation technician. The automated systems include obstacle-detection and/or safety devices (photocells, edges) that prevent the gate from closing when there is an obstacle in the area they protect.

The system ensures mechanical locking when the motor is not operating and, therefore, it is not necessary to install any lock. Manual opening is, therefore, only possible by using the release system. The gearmotor does not have a mechanical clutch and, therefore, it is coupled to a unit with an electronic clutch offering the necessary anti-crushing safety if the system is completed with the necessary safety devices. A convenient manual release with customised key makes it possible to move the gate in the event of a power failure or malfunction.

MANUAL OPERATION

Warning: Cut power to the system to prevent an involuntary pulse

from activating the gate during the release manoeuvre

To release the operator proceed as follows:

1) Insert the key provided and turn it clockwise as shown in Fig. 01 ref. 1 and 2.

2) Turn the release system clockwise, until the mechanical stop is reached, Fig. 01 ref. 3.

3) Open and close the gate manually.

RESTORING NORMAL OPERATION

Warning: Cut power to the system to prevent an involuntary pulse

from activating the gate during the manoeuvre for restoring normal operation.

To restore normal operation proceed as follows:

1) Turn the release system anti-clockwise, until its stop is reached, Fig. 02 ref. 1.

2) Turn the key anti-clockwise and remove it from the lock, Fig. 02 ref. 2 and 3.

3) Move the gate until the release system meshes (corresponds to gate locking).

4) Power up the system.

MAINTENANCE

To ensure trouble-free operation and a constant safety level, an overall check of the system should be carried out every 6 months. A form for recording routine maintenance operations is enclosed.
