NUMBERED KEY RELEASE CAP (Fig. 30).
- Open the lock protection flap.
- Insert the key into the lock and turn.
- Turn the release cap
anticlockwise
.
- Perform the gate opening or closing operation manually.
- Turn the release cap
anticlockwise
.
7. RETURN TO NORMAL OPERATION
To prevent an accidental impulse from activating the
gate during the operation, turn off the electricity supply to
the system before relocking the operator.
LEVER RELEASE DEVICE (Fig. 29)
- Insert the lever provided into the triangular slot release
device and turn
anticlockwise
by about half a revolution.
- Refit the release device rubber cap
- Move the gate until the release device engages.

- Insert the key into the lock and turn.
- Turn the release cap
anti-clockwise
.
- Move the gate until the release device engages.
8. MAINTENANCE
When performing maintenance always check that the
anti-crushing clutch is correctly regulated and that the
safety devices operate correctly.
8.1.
TOPPING UP WITH OIL
Check the quantity of oil in the operator periodically.
For medium-low duty cycles an annual check is sufficient;
for more intense use it is advisable to check every 6
months.
The level must not fall below the reference notch on the
dipstick attached to the oil filler cap (Fig. 31).
To top up, unscrew the filler cap (Fig. 31) and pour in oil up
to the correct level. Use exclusively FAAC XD 220 oil.

ACCESSORIES AVAILABLE
10.1
CORD-OPERATED MANUAL RELEASE
If the gear motor is installed in an inconvenient position, it
is advisable to use the accessory shown in Fig. 32 to
perform the release operation. Pulling on cord A releases
the system, whereas pulling on cord B relocks the gear
motor.
Important
: When the automation is reset, move the gate
until the release device engages before sending a control
impulse.
5.6.
OPERATION OF ADL LIMIT SWITCH
The ADL limit switch detects the number of pinion rotations
by means of a toothed belt transmission.
The operator is supplied with the drive in idle and the ADL
system positioned in the mid-travel position. Removing the
safety tab engages the transmission.
IMPORTANT
: If the tab has already been removed by
mistake, thereby losing the centre-scale position of the
ADL, the following steps must be carried out to restore the
start condition:
1) Release the operator.
2) Slide the gate manually to the mid-travel position.
3) Remove the rack element so as to free the pinion.
4) Turn the pinion by hand clockwise or, if the pinion
becomes hard to turn, anticlockwise until the ADL
(centre scale) LED lights up continuously.
5.7.
ALARM CONDITIONS
The ADL LED flashes in the following cases:
1) ADL system overrun.
2) Incorrect position of dipswitch SW8.
3) ADL connector removed.
4) Opening/closure time longer than 120 seconds.
The warning light (if connected) flashes at the same time
as the ADL LED.
While this condition is active all the control unit functions
are inhibited. It is possible to return to normal conditions
only after eliminating the cause of the alarm and pressing
the RESET button on the control unit.
N.B.:
When the warning light flashes with the ADL LED off,
this means that fuse F2 has blown.
5.8.
REGULATING THE TRANSMITTED TORQUE
To regulate the transmitted torque turn the screw on the
electric motor shaft (Fig. 11).
To increase the torque, turn the screw clockwise.
To reduce the torque, turn the screw anticlockwise.
IMPORTANT
: THE OPERATOR IS DELIVERED WITH THE CLUTCH
SET TO MAXIMUM, SO THE SCREW MUST BE TURNED
ANTICLOCKWISE TO REACH THE OPTIMAL SETTING.
Activate the operator and stop the gate manually to
check that the clutch engages. Bear in mind that when
this is done with model 820 the electronic anti-crushing
device cuts in and stops the movement of the gate if it is
opening and reverses it if it is closing.
The electronic anti-crushing device activation threshold
depends on the setting of the mechanical clutch.
5.9
TESTING THE AUTOMATION
When installation is complete, affix the danger warning
label to the top of the casing (Fig. 28). Thoroughly check
operation of the automation and all connected
accessories.
Give the customer the User Guide. Explain correct use and
operation of the gear motor and draw attention to the
potential danger zones of the automation.
6. MANUAL OPERATION
If it is necessary to operate the gate manually due to a
power failure or malfunction of the automation, operate
on the release device as follows.
LEVER RELEASE DEVICE (Fig. 29)
- Remove the release device rubber cap.
- Insert the lever provided into the triangular slot release
system and turn
clockwise
by about half a revolution.
- Open or close the gate manually.
