has already been reduced by the necessary 20 mm.
5 Make sure the operator is kept perfectly level and mark the point where the bracket will be attached to on the wing.
Temporarily weld or bolt the bracket in place as shown in Fig.5.
6 Release the operator and swing the gate by hand to check it moves freely to fully open and stops on the gate stop. The wing must move smoothly
and evenly.
7 Anchor the bracket permanently.
NOTE: Vent plug.
Next to the vent a dead hole has been provided where the plug and gasket can be kept for future use.
On removing the plug and during the first operator manoeuvres a small quantity of oil may leak out. This is perfectly normal and should not be con-
sidered a fault.
8) MANUAL AND EMERGENCY GATE OPERATION (FIG.7-8)
If there is a power failure or malfunction the wings can be moved by hand as follows:
Models with hydraulic lock
(HD.35 C -HD.35 AC - HD50.AC):
• Use the special key supplied with the operator to open the protective cover of the release mechanisms (Fig.7).
• Turn the knob anticlockwise to disengage the automation. (Fig.8) The knob should be rotated until it stops (approx. 3 rotations).
Do not use wrenches or tools to turn the knob.
• Now you can manually open/close the door, accompanying movement of the door for its entire stroke.
• The wing can now be opened and closed manually.
Do not use wrenches or tools to turn the knob
• To engage the automation turn the knob anticlockwise.
• Lock the cover shut.
Models without hydraulic lock (HD.35 - HD.45 - HD.50):
Since these models are reversible, simply open the electric lock and the wing can be moved manually.
Slowly push the wing by its outer end, accompanying it all the way to the gate stop. The movement may be made easier by slackening the release knob.
The manoeuvre can be facilitated by loosening the release knob, similar to models equipped with a hydraulic lock.
9) ADJUSTING THE THRUST (FIG.9)
The operator is equipped with anti-squash by-pass valve that limit the thrust on the wing when it meets an obstacle. Once the obstacle is removed
the wing will continue its stroke for the work time set by the control unit.
• Open the protective cover and use a 6 mm hexagonal key to adjust the thrust (Fig.9).
• There are two adjustable valves, one governs the opening thrust (Open), the other governs the closing thrust (Close).
• Turn the valve towards + to increase the thrust on the wing and vice-versa (i.e. towards - ) to reduce the thrust.
CAUTION! This adjustment is directly linked to the safety level of the automation.
Make sure that the thrust applied on the wing complies with statutory regulations.
10) CLOSURE SLOWING ADJUSTMENT (FIG.10)
If you want to enable slowing during the closure phase, rotate the adjustment screw indicated in Fig. 10 using a 3mm hex key.
The actuator is provided with disabled slowing (screw completely rotating in + direction)
Rotating in the - direction, slowing is enabled, on increasing rotation slowing in the closure phase becomes more obvi-ous.
Attention: Do not completely fasten the screw in (direction -) to avoid the rod locking.
11) THE PROTECTIVE COVERS (FIG.11)
After adjusting the slowdown the covers can be replaced (Fig.11).
Take great care in ensuring that the drain hole faces the ground.
12) WIRING (FIG.12)
The operator is supplied with the wiring cable already installed and wired (Fig.12). To connect it to the control unit see the diagram and instructions
for the control unit.
The power cable is best protected by a 12mm spiral sheath that has to be inserted in the coupling provided.
An earth connection is compulsory.
13) TOPPING UP/CHANGING OIL (FIG.13)
The oil level in all hydraulic operators must be periodically checked.
To top up the oil first shut-off the mains power to the system and then remove the two screws on the terminal block, which also acts as oil cap.
The level must never rise above the rim shown in Fig.13. Only use HYDRO OIL.

N.B.: The power cables must be kept separated from the auxiliary cables.
IMPORTANT: Installation of an electric lock is essential on models without hydraulic lock or if the wing is over 1.8 m long
