AUTOMATED SYSTEM 740-24V
Read the instructions carefully before using the product and keep them for future
consultation.
GENERAL SAFETY RULES
If installed and used correctly, the 740-24V 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 740-24V automated system is ideal for controlling vehicle access areas of
medium transit frequency.
The 740-24V 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 radio-
control 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 instal-
lation technician.
The automated systems include obstacle-detection and/or safety devices (pho-
tocells, 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
ENGLISH
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.
REPAIRS
