For the gate automation to work properly, the actual gate must have the following characteristics:

- it must be robust and rigid.

- the hinges must have only limited play and provide smooth and gentle gate movements.

- the whole height of the wings must be in contact when closed.

If they are not already provided, install gate stops on the opening and closing stroke limits (Fig.3) regardless of the type

of operator being installed.

The mechanical stop in close position is compulsory because of the particular characteristics of the hydraulic actuators.

1 Establish the height of the automation from the ground (preferably as close to the centre of the wing as possible and

along a solid cross rail).

Remember that under the operator there is a vent hole and in certain conditions (e.g. rain or snow) it may draw liquid

into the automation. For this reason it is best not to install the operator too close to the ground.

2 Weld or otherwise anchor plate P in place, see installation distances (Fig.2) and the installation diagram (Fig.5):

- insert pin P in bracket P as in the ﬁgure

- insert the fork F of the HD.80 into the bracket P

- lock everything in place by washer R and self-locking nut D

- remove the vent plug VS with its gasket RS. (see note "Vent plug")

Observe the distances given in the tables at ﬁg. 2, correcting the length of the plate if necessary. In some cases a

recess may have to be made in the post.

It is essential that the installation distances are respected for the operator to work correctly.

With reference to the installation tables note that:

For the wing to open 90°:

For the wing to open more than 90°:

Keep the length differences within 40mm. Over this difference the wing movement becomes uneven. When reducing

lengths A and B , increase the wing speed.

Comply with all statutory regulations.

3 Slide out the ram shaft completely and then slide back in by approx. 10 mm. Lock the operator in place.

Always leave a safety overrun of 10 mm in both the closing and opening strokes. The stroke length given in the techni-

cal data and installation tables has already been reduced by the necessary 20 mm.

4 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.6.

5 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.

6 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 considered a fault.

Being reversible, the motors HD.80 can be released simply by unlocking the electric lock, after that the leaf can be

operated manually.

Slowly push the wing by its outer end, accompanying it all the way to the gate stop.

The operation can be made easier by loosening the release valve (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 (Fig.7) 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.

all the versions are provided with slow down in close and open position for a slower movement during the last seconds

of the maneuver.

ìThe slow down in both direction starts in the last part of the stroke, so it is very important to use the whole stroke and

respect the indicated installation geometry.

A+B must be equal to the operator stroke

A+B must be less than the operator stroke.
