C720-721 Manual

GENERAL SAFETY REGULATIONS

The C720 and C721 automated systems, if correctly installed and used, guarantee a high level of safety.

• Obeying some simple rules can also prevent accidental problems:
• Do not allow children or adults to stay near the automated system, particularly avoid it while it is operating.
• Keep radiocontrols or other pulse generators away from children, to prevent the automated system from being activated involuntarily.
• Do not allow children to play with the automated system.
• Do not forcibly restrain the gate’s movement.
• Prevent branches or shrubs from interfering with gate movement.
• Keep the illuminated signalling systems efficient and very visible.
• Do not attempt to operate the gate by hand until it has been released.
• In the event of malfunction, release the gate to allow access and wait for qualified technical personnel to repair it.
• Once manual operating mode has been set, turn off the power supply to the system before restoring normal operation.
• Do not in any way modify the components of the automated system.
• The user must not attempt any kind of repair or direct action whatever and contact qualified personnel only.
• Ensure the efficiency of the automated device, the safety devices and the earth connection are checked at least every six months by qualified personnel.

DESCRIPTION
The C720 and C721 automated systems are ideal for controlling vehicle access areas with average transit frequency. The C720 and C721 automated systems for sliding gates are electromechanical operators that transmit the motion to the sliding leaf using a rack and pinion. The operation of the sliding gate is managed by an electronic control device housed inside the operator or in a watertight outdoor container.

When the device receives an opening command via a radiocontrol or any other suitable device with the gate closed, it operates the motor until the gate reaches its open position. If automatic operation has been selected, the gate re-closes by itself after the selected pause time. If semi-automatic operating mode has been selected, a second pulse must be sent to re-close the gate. An opening pulse issued during the re-closing stage always causes a reversal of motion.

A stop pulse (if applicable) always stops motion. The warning light indicates the current gate movement. For the detailed behaviour of the sliding gate during the various operating modes, consult the installing technician. The automated systems contain obstacle detection and/or safety devices (photocells, edges) that prevent the gate closing when an obstacle is located in the scanned area.
