844R 3Ph AUTOMATED SYSTEM
Read the instructions carefully before using the product, and
keep them for future consultation.
GENERAL SAFETY REGULATIONS
If installed and used correctly, the 844R 3Ph automation will
ensure a high degree of safety.
Some simple rules regarding behaviour will avoid any accidental
trouble:
-
Do not stand near the automation and do not allow children
and other people to stand there, especially while it is
operating.
-
Keep remote controls or any other pulse generator well away
from children to prevent the automation from being activated
involuntarily.
-
Do not allow children to play with the automation.
-
Do not willingly obstruct gate movement.
-
Prevent any branches or shrubs from interfering with gate
movement.
-
Keep illuminated 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 operating mode, switch off the power
supply to the system before restoring normal operating mode.
-
Do not make any alterations to the components of the
automation.
-
Do not attempt any kind of repair of direct action whatever
and contact qualified FAAC personnel only.
-
Call in qualified personnel at least every 6 months to check
the efficiency of the automation, safety devices and earth
connection.
DESCRIPTION
The 844R 3Ph automation is ideal for controlling industrial vehicle
access areas.
The 844R 3Ph automation for sliding gates is an
electromechanical operator which transmits movement to the
sliding leaf via a pinion with rack or chain appropriately coupled
to the gate.
Operation of the sliding gate is controlled by electronic control
equipment housed in a container separated from the operator
(844 T).
When, with the gate closed, the control equipment receives an
opening command by remote control or from another suitable
device, it activates the motor until the opening position is
reached.
If automatic operating mode was set, the gate closes
automatically after the selected pause time has elapsed.
If semiautomatic operating mode was set, a second pulse must
be sent to allow the leaves to close again.
An opening pulse during re-closing, always causes movement
to reverse.
A stop pulse (if supplied) always stops movement.
For details on sliding gate behaviour in different function logics,
consult the installation technician.
Automations include safety devices (photocells, sensitive 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, installing any lock is unnecessary.
Manual opening is, therefore, only possible by using the release
system.
The gearmotor has an adjustable mechanical clutch providing
the necessary anti-crushing protection.
An inductive sensor detects transit of metal plates secured on
the rack, which correspond to the travel limit positions. The

electronic control equipment is housed in a container which is
separate from the gearmotor.
A handy manual release facility makes it possible to move the
gate in the event of a power cut or fault.
The warning-light indicates that the gate is currently moving.
MANUAL OPERATION
If the gate has to be moved manually due to a power cut or
fault of the automatic system, use the release device as follows:
1) Open the protective door and fit the supplied key in the lock
(Fig. 1).
2) Turn the key clockwise and pull the release lever as shown in
Fig. 2.
3) Open and close the gate manually.
RESTORING NORMAL OPERATION MODE
To avoid an involuntary pulse from activating the gate during
the manoeuvre, before re-locking the operator, switch off power
to the system.
1) Re-close the release lever.
2) Turn the key anticlockwise.
3) Remove the key and close the lock protection door.
4) Move the gate until the release mechanism meshes.
