11) SLOW-DOWN ADJUSTMENT
The models available for this device allow the speed to be slowed down in
the end-of-run phase. They allow opening and closing manoeuvres free from
any slamming noise. The slow-down phase is activated about 15°-20° before
the closing or opening manoeuvre is completed. Fig. 29 shows adjustment
screws "A" and "C" for opening and closing respectively. These are adjusted
by means of a 3 mm Allen key.
12) EMERGENCY MANOEUVRE
The irreversibility of the reduction gear unit allows the overhead door to be
tightly held in the closing and opening position, and makes the use of an
electric lock redundant.
Knob release or wire command systems are available.
- The knob release device is activated by unscrewing the knob anticlockwise
(fig. 30). To reactivate motor-driven operation, fully screw the release knob.
- The SEB version release device with wire command (fig. 31) must be used
when the garage does not have a secondary access. The wire command
device allows the door to be released from the outside by inserting the
personalised key into the appropriate lock, which is to be rotated by about
180° to activate the release for manual opening. In the case where the
release must be activated from the inside (fig. 32), manually rotate lever "L"
from position "A" to position "B", and keep it in the required position during
the entire manoeuvre.
Motor-driven operation is restored by removing the key from the external
release lock or simply by releasing lever "L" from the inside.
13) THE CONTROLS
With the automation the door 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 con-
trols.
14)OPERATOR USE
Since the operator can be remotely controlled by means of a radio transmitter
or Start button, it is indispensable to check all safety devices frequently for
perfect efficiency.
Any operation malfunction must be rapidly corrected by qualified personnel.
It is recommended to keep children well away from the operator working
range.
15) CONTROL
Operator use allows the door to be opened and closed automatically. There
are different types of control devices (activated manually, by radio transmitter,
access controls with magnetic badges etc.) according to installation requi-
rements and characteristics. See the relevant instructions for the various
control systems.
All operator users must be instructed on correct operator control and use.
16) MAINTENANCE
Before carrying out any maintenance to the operator, disconnect the system
from the mains power supply.
• Periodically check the system for oil leaks.
Top up with oil of the same type only (see data given in the table) and
proceed as follows:
a) Remove the plug "T" (Fig.1).
b) Top up using the prescribed oil until its level reaches 1.5 mm on the oil
plug hole.
c)Carefully refit all of the components.
WARNING – The oil must be completely replaced every two years. It is strictly
recommended to use oil of the same type (see data given in the table).
• Check the safety devices of the automation.
When any operational malfunction is not resolved, disconnect the power
supply from the system and request the assistance of qualified personnel.
17) MALFUNCTIONS AND REMEDIES
17.1) The motor does not tu0rn
- Check that the control unit is correctly supplied with power, the fuses are
undamaged, and the diagnosing LEDs indicate the correct functions (see
instructions for the control unit).
- Use an appropriate instrument to check the presence of voltage at the
ends of the gearmotor after the opening or closing command.
- If the motor vibrates but does not turn, it may be due to:
A) wrong connection of common wire C (blue in all case);
B) no connection of the drive capacitor to the terminals provided in the
control unit.

INSTALLATION MANUAL
17.2) The motor turns and the door does not open
- The emergency release is activated: restore motor-driven operation.
- Motor drive connections are reversed. Try and reverse them at the control
unit terminals.
- Operation time in the control unit could be set to minimum.
- Check the oil level (see paragraph on maintenance), top up if necessary.
The oil must be topped up by qualified personnel.
17.3) Faulty operation of electrical accessories
In case of any fault, all the control and safety devices can cause operation
anomalies or lock of the actual operator.
To identify the fault, all the operator devices must be disconnected, one by
one, until the cause of the fault is identified. After repairing or replacing any
faulty device, reset all the previously disconnected devices. For all the devices
installed, make reference to their respective instruction manual.
WARNING: This operation must be carried out by qualified personnel. During
maintenance operations, the door operating area must be properly indicated
and enclosed in order to avoid any danger to persons, animals and things.
18) NOISE LEVEL
The aerial noise produced by the gearmotor in normal operating conditions
is constant and does not exceed 70 dB(A).
19) 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 materials to be recycled, these should be sorted out by type
(electrical components, copper, aluminium, plastic etc.).
20) DISMANTLING
When the operator is disassembled to be reassembled at another site,
proceed as follows:
• Disconnect the power supply and the entire electrical installation.
• Remove the gearmotor from the fixing base.
• Disassemble the control panel, if separate, and all the installation com-
ponents.
• In the case where some of the components cannot be removed or are
damaged, they must be replaced.
