ENGLISH
the mechanical multiple-disk clutch (fig.23).
The adjustment of the clutch must be carried out by qualified personnel
(installer) and includes the calibration of the clutch to the minimum force
needed to complete full opening and closing strokes. The calibration must
never exceed the values of the pushing force measured on the leaf edge
according to the national standards in force. In Italy the admitted value is
equal to 150N.
WARNING! Do not secure completely the adjustment screw of this
device; this could compromise the safety of the automation and the
controller could get damaged.
Carry out the adjustment as follows:
Remove the cover "A" and rotate from time to time small sections of the
screw "C" using the appropriate spanner "B". To tighten the clutch, rotate
the screw clockwise (towards +), to loosen the clutch, rotate the screw
anticlockwise (towards -).
Carry out the adjustment on every controller mounted and refit the cover "A".
Fig.24 indicates the assembly sequence for the clutch components: A)
cover, C) adjustment screw, E) Belleville washer, F) clutch disks with inside
keying, G) clutch disks with outside keying, H) arm, I) shim washer, L)
grooved reduction shaft.
9) LIMIT SWITCHES
The controllers are not equipped with electric limit switches. For this
reason, they must be controlled by a control unit with adjustment of the
operation time. When the leaf reaches the gate stop limit the clutch slides
and the motor remains energised until the total operation time set has
elapsed. The operation time can be set on the control unit by means of a
trimmer. The time is correct when the time set is 3-5 seconds greater than
the actual time needed to complete one full opening and closing cycle. If the
leaf is too slow, adjust the operation time in closing position. The less the
movement time at the end of stroke is, the longer the clutch life will be.
If external electric limit switches are used, refer to the two different
installation methods in fig.25-26. The limit switches must be sealed. To
connect the limit switches, refer to the instructions for the control unit.
10)EMERGENCY MANOEUVRE
Since the gearmotor is reversible, release the electric lock and move the
leaves manually in the case of a power failure. When the power supply has
been restored, the automation operates automatically.
11) CHECKING THE AUTOMATION
Before considering the automation completely operational, the following
checks must be made with great care:
Check that all the safety means work properly (i.e. clutch, photocells,
pneumatic skirts, etc.).
Check that the thrust (anti-squash) of the leaf is within the limits prescribed
by the standards in force.
Check the manual opening control.
Check the opening and closing manoeuvres using the controls.
Check the control unit's electronic logic in normal or customised operation.
12) USE OF THE AUTOMATION
Since the automation may be remote controlled either by radio or a start
button (and therefore not visually), it is essential that all safeties are
checked frequently.
Any malfunction should be corrected immediately by qualified personnel.
Keep children at a safe distance from the field of action of the automation.
13) THE CONTROLS
With the automation the gate has a power driven opening and closing. The
controls can come in various forms (i.e. manual, remote controlled, limited
access by magnetic badge, etc.) depending on needs and installation
characteristics. For details on the various command systems, consult the
specific instruction booklets.
Anyone using the automation must be instructed on its operation and
controls.
14) MAINTENANCE
All maintenance operations must be performed with the system power
supply shut off.
Lubricate periodically the articulated elements of the drive arm.
Clean the optical system of the photocells every now and then.
Have the adjustment of the electric clutch checked by a qualified specialist
(installer).
For any malfunction that remains unsolved, shut off the power to the system
and call a qualified specialist (installer).

15) NOISE
The aerial noise produced by the gearmotor under normal operating
conditions is constant and does not exceed 70dB(A).
16) SCRAPPING
Materials must be disposed of in conformity with the current regulations.
In case of scrapping, the automation devices do not entail any particular
risks or danger. In case of recovered materials, these should be sorted out
by type (electrical components, copper, aluminium, plastic etc.).
17) DISMANTELLING
When the automation system is disassembled to be reassembled on
another site, proceed as follows:
• Disconnect the power supply and the entire electrical installation.
• Remove the gearmotor from its fixing base.
• Disassemble the control panel, if separate, and all installation
components.
• In the case where some of the components cannot be removed or are
damaged, they must be replaced.
18) TROUBLESHOOTING
18.1) The gate does not open. The motor runs, but the opening
movement does not start.
1) Check if the electric lock works correctly.
2) Check if the mechanical arrangement of the gate is faulty, e.g. there are
interferences with the gate stop limits or between the edges of the leaves.
3) Check if the clutch slides and, if necessary, tighten it by rotating the screw
towards the + sign (max. thrust allowed 150N).
4) If the motor runs in the direction opposite to the right one, invert the driving
connections of the motor (check rotation by lifting the clutch cover).
If after having carried out the checks listed above the problem persists,
replace the controller.
18.2) The gate does not open or close. The motor does not run and no
sound is heard.
1) Check that the control unit is correctly powered.
2) Check that the photocells or the rubber skirts are not engaged.
2) Check that the electronic equipment is correctly powered. Check that the
fuses are not damaged.
4) Check that the electronic functions of the equipment are correct by means
of the diagnostic LEDs or through a visual inspection.
5) Check that no remote controls, start buttons or other devices are keeping
the start contact (N.C.) closed.
If after having carried out the checks listed above the problem persists,
replace the control unit.
18.3) The noise originating from the motor is high when the leaf
encounters the gate stop limit.
1) When the clutch slides because the leaf has reached the gate stop limit,
the leaf must be still and no oscillations should be noticed. If jog movements
are noticed, reinforce the leaf so as to eliminate the problem.
2) If the leaf cannot be reinforced, decrease the working time so that the
clutch slides as little as possible.
3) If the disks are bright, restore them with sandpaper or, if necessary, replace
them.
