• Before installing the operator read these instructions.
• Use of a hydrO product for any application not described in this instruction manual is prohibited.
• The user must be instructed on the use of the automation system.
• The user must be consigned the instruction manual.
• All CAB products are insured against damage or injury caused by manufacturing defects under the essential condition
that the operator has the CE marking and all genuine CAB components are installed.
Hydraulic operator for swing gates, available in various versions:
hd.18 ac/hd.30 ac
hd.30 c
hd.25/hd.30
Models without hydraulic lock on opening stroke always require an electric lock to guarantee the wing is locked shut
mechanically.
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 closed stop in particular is indispensable given the special characteristics of hydraulic operators. See "maintain stop"
function in the instructions for the control unit.
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):
- remove screws V and cover C
- insert pin P in bracket P as in the figure
- 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 Release the operator (see section "manual gate operation")
4 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.
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.
