3. ELECTRICAL EQUIPMENT ARRANGEMENT
Figure 3 shows the layout of the electrical equipment required for
installing the 5413ph operator with 844T remote equipment.
4. PRELIMINARY CHECKS
The door structure must be suitable to be automated and must
conform to standards EN12604 and EN 12605.
The rope winding shaft must have a keyway. It must project laterally
by a width sufficient to install the operator and the key locking
collars (operator mounted directly on shaft) or to secure the crown-
gear (mounting with chain transmission - optional item). Some door
manufacturers supply special joints with shaft, which makes it possi
-
ble to motorise doors which were built without the required facility.
Check the efficiency of bearings, wheels, parachute system, door
rail and joints. Also make sure that the traction ropes are perfectly
fitted in the grooves of the drums, do not come into contact with
mechanical parts or fixed parts of the structure, and are subjected
to the same degree of tension.
Make sure that there is no friction on the door: the door must slide
smoothly when both opening and closing.
Check if the door is well balanced: if stopped in any position, it
must remain still.
Remember that European standards EN12604 and EN12453 pre
-
scribe 260N, for manually moved doors, as the maximum limit of
force applied to the handles for manual manoeuvre, and 390N
for motorised doors.
Consult the technical documentation of the door to find out the
shaft torque required for movement and the number of revs ne

Consult table 1 to see which type of installation (directly on shaft
or chain transmission with reduction) satisfies the declared speci

fications.
The efficiency and safety of the automated system are closely
linked to the above. You therefore must get in touch with the door
manufacturer or installer if you encounter any problems. Remove
the door mechanical closures to ensure the door is locked by the
automated system. Remove the manual activation device if sup
-
plied. Check if an efficient earthing system is available for electrical
connection to the operator.
5. INSTALLING THE OPERATOR
To work under safe conditions, we advise you to install the operator
while keeping the door fully closed and to read the whole of this
chapter before starting to install.
The 541 3ph operator has a 25.4 mm (1”) power take-off. If the dri
-
ve shaft is of a different size, the chain transmission (optional item)
must be installed.
The manual activation devices (release and chain drive) are desig
-
ned for installation at a height of up to 4 metres. To install at greater
heights, use the extension kits (optional items).
The operator is equipped with four microswitches with the following
functions:
•Opening limit-switch
•Closing limit-switch
•Winch safety switch (only on models supplied with the manual
manoeuvring system)
•Release control safety switch
The supplied support plate will enable you to secure the operator
at a maximum distance of 125mm between the anchoring point
(wall or metal structure) and the power take-off axis.
Before installing, we advise you to check the rotation direction of
the power take-off (see paragraphs 5.7).
For all matters referring to the electrical system, please consult the
chapter entitled “Warnings for the installer” and chapters 3 and 6
of these instructions.
The supplied
Cordura
handle can be installed, using the plate fa
-
stening points, on the operator, to facilitate the shifting operations
during the preliminary stages of installation.
