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.6.
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 considered a fault.
If there is a power failure or malfunction the wings can be moved by hand as follows:
Models with hydraulic lock (i.e. Hydro BA - Hydro BC -Hydro BAC):
• 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 wing can now be opened and closed manually.
• To engage the automation turn the knob anticlockwise.
• Lock the cover shut.
Models without hydraulic lock (i.e. Hydro - Hydro L - Hydro Plus):
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 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.
All models are equipped with slowdown in the closing stroke, so that the wing reduces speed during the last few
seconds of its stroke.
The slowdown is adjusted by a valve (Fig.10).
Use a 3mm hexagonal key:
- open (i.e. turn anticlockwise) the valve to increase the slowdown speed.
- close (i.e. turn clockwise) the valve to reduce the slowdown speed.
To bypass the slowdown function fully unscrew the valve.
Never force the adjustment valve.
After adjusting the slowdown the covers can be replaced (Fig.11).
Take great care in ensuring that the drain hole faces the ground.
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.
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.
