8.4) Installation with slide arm (to one side of the hinge-pivot)
This type of installation is illustrated in fig.9. The installation method is
described in paragraph 6.5. Furthermore, the actuator support base must
be tightly secured to the foundation base by means of screws, and not just
fastened by the four angle bars as in the case of installation under the hinge-
pivot.
9) STOP PLATES
The use of ground stop plates "F" (fig.20) is compulsory both on opening
and closing. The stop plates must lock the leaf while maintaining a safety
extra-stroke of 5° at least (fig.12).
10) LEAF PHASE DIFFERENCE
In the case where the leaves overlap during the closing manoeuvre, the
phase difference on closing is set by means of the appropriate trimmer
included in the electronic control unit. The motor of the delayed leaf must
be connected to the terminals of the control unit, which are identified by the
"Mr" symbol as illustrated in the control unit wiring diagram.
11) ELECTRIC LOCK FITTING
This is only needed for models without hydraulic lock on closing (Table 1).
The EBP mod. electric lock (fig.16) consists of a continuous- service
electromagnet hooked to the ground. This device remains energised during
the whole gearmotor operation time, allowing catch "D" to reach the closing
stop point without opposing any resistance; this factor allows the pushing
load to be reduced on closing, thus improving antisquash safety.
12) PUSHING FORCE ADJUSTMENT (Fig.1)
This is obtained by means of two valves, marked by the writing "close" and
"open" respectively, used to adjust the pushing force on closing and
opening. If the valves are turned towards the "+" sign the force is increased,
if they are turned towards the "-" sign it is decreased. To obtain 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, pneumatic
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 immediate
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.
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
manoeuvring, 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, disconnect
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
