3. ELECTRICAL EQUIPMENT ARRANGEMENT
Figure 3 shows the layout of the electrical equipment required
for installing the 540 operator.
Figure 4 shows the layout of the electrical equipment required
for installing the 541 operator with 578D 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 possible 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
prescribe 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
necessary for complete opening.
Consult table 1 to see which type of installation (directly on shaft
or chain transmission with reduction) satisfies the declared
specifications.
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 supplied.
