Read the instructions carefully before using the product and keep for any
future needs.
GENERAL SAFETY REGULATIONS
The C720 / 1800 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 quali-
fied technical personnel to repair it.
Once manual operating mode has been set, turn off the power supply to the sys-
tem 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 con-
tact 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 / 1800 and C721 automated systems are ideal for controlling vehicle
access areas with average transit frequency.
The C720 / 1800 and C721 automated systems for sliding gates are electrome-
chanical 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 an-
ticrushing 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 in-
stalled) 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. 1. The re-
lease lever will move slightly away from the operator body
(Fig. 1 re. 2)
Fully lower the release lever to the mechanical stop Fig. 1 re.
3.
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.
1.
Turn the release anticlockwise as shown in Fig. 2 re. 2.
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 devic-
es (including the motor thrust force, which must comply with
current standards) and of the release devices.
