Read the instructions carefully before using the product and store
them for future use.
GENERAL SAFETY REGULATIONS
If correctly installed and used, 541 3ph automated systems ensure
a high degree of safety.
Some simple rules on behaviour can prevent accidental trouble:
- Do not, under any circumstances, stand under the sectional door.
- Do not allow children, persons or things to stand near the automa -
ted systems, especially while they are operating.
- Keep remote-controls, or other pulse generators that could open
the door, well away from children.
- Do not allow children to play with the automated system.
- Do not willingly obstruct door movement.
- Prevent any branches or shrubs from interfering with door move -
ment.
- Keep warning-lights efficient and easy to see.
- Do not attempt to activate the door by hand unless you have
released it.
- Make sure that there are no persons, animal or things near the
door before releasing the door.
- In the event of malfunctions, manually activate or release the
door to allow access and wait for qualified technical personnel
to do the necessary work.
- When the operator is released, before restoring motorised opera -
tion, make sure that the system is not powered.
- Do not in any way modify the components of the automated
system.
- Do not attempt any kind of repair of direct action whatever and
contact qualified FAAC personnel only.
- At least every six months: arrange for qualified personnel to check
efficiency of the automated system, safety devices and earth
connection.
- Arrange for qualified personnel to check the door at the intervals
recommended by the manufacturer, addressing special attention
to the safety systems and balancing.
- Transit under the door is permitted only when the automated
system is idle.
DESCRIPTION
The 541 3ph automated systems are ideal for activating balanced
industrial sectional doors.
They consist of an electro-mechanical operator and remote
electronic control equipment. The non-reversing system ensures
mechanical locking of the door when the motor is not operating
and, therefore, no lock needs to be installed. Operator release and
a manual manoeuvring system (the latter is only supplied on the
models for which it is specified), make the door manoeuvrable in
the event of a power cut or malfunction.
The door is normally closed; when opening is commanded, the
equipment activates the electric motor which drives the door to
opening position to permit access. In “dead-man” systems, the
command push-button must be kept pressed for the whole duration
of the opening or closing manoeuvre.
In the automatically operating systems:
- If the automatic logic was set, the door closes after pause time
has elapsed.
- If the semi-automatic logic was set, a second pulse must be sent
to close the door.
- A stop pulse (if supplied) always stops movement.
For full details on the behaviour of the automated system in the
different logics, consult the installation Technician.
Automated systems may include safety devices (sensitive edges,
photocells) that prevent the door from closing and/or opening when
there is an obstacle in the area they protect. Emergency manual
opening is possible by using the release system.
Manual command is possible by activating the chain-operated
winch (for models with which it is supplied).
Electric command is disabled during the manual manoeuvre or
when the operator is released.
The warning-light, where supplied, indicates that the door is cur -
rently moving.
MANUAL OPERATION (541 3ph with winch)
If the door has to be activated and the automated system is
inactive due to a power-cut or malfunction, the door opening and
closing manoeuvres can be done by hand, by using the chain-
operated winch. Check the indicator sign to see which branch of
the chain has to be activated to perform the required manoeuvre.
Pull downward only the branch involved.
If no indicator sign is present, pull one of the chain branches wi -
thout forcing and check if the door tends to move in the required
direction. If not, activate the other branch.
While the winch is operating, the operator’s electrical control is
disabled.
RELEASING THE OPERATOR AND RESTORING AUTO-
MATIC OPERATION
The 541 3ph operators are provided with an emergency system
which can be activated from the inside.
The operator release operation must be effected with the door
closed if possible. In any event, the presence of persons, animals
and objects in the immediate vicinity of the operator is absolutely
forbidden.
If the door has to be moved manually due to a power cut or mal -
function of the automated system, cut out power to the system and
use the release device as follows: release the operator by pulling
the rope with the red knob (see figure 1) downward until the lever
reaches the travel-limit stop. To restore automatic operation, fully
close the door and pull the rope with the green knob until the lever
returns to its original position.
