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.

The system ensures the gate is mechanically locked when
the motor is not operating and no lock therefore needs to be
installed.
Manual opening is therefore only possible if the appropriate release
system is operated.
The gearmotor is equipped with a device with electronic anti-
crushing system that offers the necessary safety if the gate
should strike an obstacle during its motion by causing it to reverse
direction immediately.
A handy manual release makes it possible to move the gate in
the event of a power cut (if no back-up batteries are installed)
or malfunction.
MANUAL OPERATION
During the release/lock manoeuvre, take care
to prevent an involuntary pulse from operating
the gate.
Proceed as follows to release the gearmotor:
Turn the release clockwise as shown in Fig. 1 re.
햲
. The
release lever will move slightly away from the operator body
(Fig. 1 re.
햳
)
Fully lower the release lever to the mechanical stop Fig. 1
re.
햴
.
Carry out the opening or closing manoeuvre manually.
RESTORING NORMAL OPERATION
Proceed as follows to lock the gearmotor:
Fully raise the release lever to the mechanical stop, Fig. 2
re.
햲
.
Turn the release anticlockwise as shown in Fig. 2 re.
햳
.
To maintain the operator intact, avoid pulsing
the gate to operate before resetting the release
system.
MAINTENANCE
It is advisable to check the efficiency of the system at least
every 6 months, particularly the efficiency of the safety devices
(including the motor thrust force, which must comply with
current standards) and of the release devices.
