good antisquash safety, the pushing force must be slightly greater than
that needed to move the leaf, both on closing and opening; however,
the force, measured at the leaf edge, must not exceed the limits set out
by the current national standards. The actuator is not provided with
electrical limit switches. Therefore the motors are switched off at the
end of the operation time set in the control unit. Such operation time
must exceed by about 2-3 seconds the moment where the leaves meet
the ground stop plates. For this reason as well as for safety reasons,
under no circumstances must the by-pass valves be completely closed.
13) MANUAL OPENING
In case of emergency, for instance when there is no power available, the
gate must be opened by hand.
13.1) Versions without hydraulic locks (electric lock)
As these models are irreversible, in order to move the gate by hand you
only need to open the electric lock by means of the appropriate key,
and push the leaves with a force strong enough to win that adjusted
with the by-pass valves (approximately 15 kg/150N). In order to make
the manoeuvre easier, it may also be helpful to activate the hydraulic
lock in the way described below.
13.2) Versions with hydraulic locks (Fig.17)
- Unscrew cap "T" which is found on the cover of each actuator (usually
on the inside).
- Insert the release key supplied in triangular release pivot PST and
rotate it anticlockwise by a few turns (CS in fig.18).
- Push the leaf by hand at a speed similar to that of motorised operation.
- To restore motorised operation, turn the key clockwise until it is
completely tightened, screw the release cap onto the cover and put
the key in a place which is known to all users.
NOTE: In order to avoid oxidation of the release device, it is helpful to
fill its triangular seat with grease.
14) AUTOMATION CHECK
Before finally making the automation fully operative, carefully carry out
the following procedure:
- Check that all components are tightly secured.
- Check the correct functioning of all safety devices (photocells, pneu-
matic edge etc.).
- Check the emergency manoeuvre command.
- Check the opening and closing operations with the control devices in
use.
- Check the standard (or customised) electronic function logic in the
control unit.
15) AUTOMATION OPERATION
As automation can be remotely controlled by means of a radio control
or start button, it is essential to frequently check that all safety devices
are perfectly efficient. In case of any operational malfunction, take im-
mediate action and request the assistance of qualified personnel. It is
recommended to keep children at a safe distance from the automation
field of action.
16) CONTROL
The automation system is used to obtain motorised gate opening and
closing. There are different types of control (manual, radio, magnetic
badge access control, etc.) depending on the installation requirements
and characteristics. For the various control systems, see the relevant
instructions. All automation users must be instructed on proper control
and use.
17) MAINTENANCE
All maintenance on the controller must be performed with the systems
power supply shut off. Check periodically for oil leaks. When topping-
up the oil, always use oil of the same type (see data table) and proceed
as follows:
a) Remove the cap "P" (fig.3).
b) Top-up with oil until it reaches 1.5 mm on the oil cap hole.
c) Reassemble all of the unit.

INSTALLATION MANUAL
ATTENTION: The oil of each actuator must be replaced completely every
two years. Only use oil of the same type (see data 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.
- If the leaves move jerkily, or if excessive noise is noticed during ma-
noeuvring, this could be due to air being trapped in the hydraulic
circuit, and therefore a bleed operation may be required.
17.1) Oil bleed
NOTE: The actuator is supplied without air in the hydraulic circuit. If a
bleed operation is required, proceed as described below.
a) Remove the cover from the actuator.
b) Activate the opening command and loosen the bleed screw (S) for
opening (fig.19-20) during leaf movement.
c) Let the air out until non-emulsified oil appears (if possible, try to prevent
the oil leaking out of the bleed screw from falling into the foundation
case).
d) Tighten the bleed screw before the actuator runs out of operation
time.
e) Activate the closing command and loosen the bleed screw for closing
(which can be seen in fig.20) during leaf movement.
f) Let the air out until non-emulsified oil appears.
g) Tighten the bleed screw before the actuator operation time runs out.
h) Repeat this operation several times for both bleed screws.
i) Restore the oil level, checking that it just reaches below cap "O" (fig.19).
Top up with IDROLUX oil of the same type.
18) NOISE LEVEL
The aerial noise level produced by the gearmotor under 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 components 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.).
20) DISMANTLING
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 the installation
components.
- In the case where some of the components cannot be removed or
are damaged, they must be replaced.
21) MALFUNCTION: CAUSES and REMEDIES
When any operational malfunction is found, and not resolved, discon-
nect the power supply from the system and request the assistance of
qualified personnel (installer). When automation is out of order, activate
the manual release to allow opening and closing manoeuvres to be
carried out by hand.
21.1) The gate does not open. The motor does not turn.
1) Check that the photocells or electric edges are not dirty, or engaged,
or not aligned. Proceed accordingly.
2) Check that the electronic equipment is correctly supplied with power.
Check the integrity of the fuses.
3) Check that the functions are correct by means of the control unit
diagnosing leds (see relevant instructions). Identify any causes for
faults. If the leds show a persistent start command, check that no
radio controls, start buttons or other control devices keep the start
contact activated (closed).
4) If the control unit does not work, it must be replaced. Should the
checks listed above be satisfactory, replace the actuator.
