3 Installation
3.1 Preliminary checks
To ensure trouble-free operation, make sure that the gate (whether
existing or yet to be installed) has the following specifications:
- Max. weight of single leaf 800 kg.
- Max. width of single gate leaf 2 m.
- Strong and rigid leaf frame.
- Smooth gate movement, with no stiff points.
- Min. clearance between bottom edge of gate and ground as in
Fig. 6a (where S = thickness of guide bracket).
- Mechanical travel stops.
If any welding or brazing has to be done on the gate, do this before
installing the automation system.
3.2 Installation of leaf supporting foundation
box (Fig. 3)
Depending on the existing situation, different measures have to be
taken. The following examples are possible:
a) Existing gate with fixed hinges:
· Remove the gate.
· Remove the bottom hinge.
If the gate cannot be removed, place blocks under its bottom edge
to support it.
b) Existing gate with adjustable hinges:
· Remove the bottom hinge.
· Slacken off the top hinge.
· Swing the leaf around the axis of the top hinge (Fig. 4).
c) New gate to be installed:
· Fit just the top hinge. If possible use an adjustable hinge.
- Carry out the foundation with cutout according to Fig. 5. The
foundation must be frost-resisting.
- Place the base box in the hole, making sure that you respect the
dimensions given in Fig. 6a/b. The centre of the pinion must be
perfectly aligned with the leaf's axis of swing.
Note:
A telescopic template is available to facilitate base
box positioning as shown in Fig. 7.
- Lay out an installation tube of diameter 40 mm through which to
pass a 4 core electrical cable. The tube must reach from the box
to the control unit (Fig. 8). Lay a second tube to drain off rain
water, from the box to the nearest drain (Fig. 8).
- Fix the box in place with a casting of concrete.

3.3 Setting up the gate
Note:
Wait for the cement to set before starting this work.
- Prepare the gate's guide bracket as follows:
· Use a U-profile of the dimensions given in Fig. 9.
· Ascertain the correct location for the bushing to suit the
position of the gate with respect to the axis of rotation (Fig.
10a/b).
· Place the bushing so that one notch aligns with the centre-
line of the U-profile (Fig. 11).
Attention:
This alignment is essential to the correct operation
of the gate automation system.
· Carefully weld the bushing to the U-profile (Fig. 12).
· Seal the U-profile on the post side with a plate as shown in
Fig. 13a/b.
- Grease the pinion.
- Fit the guide bracket over the pinion so that the tooth with the
punch mark engages in the bushing notch aligned along the
centre-line of the bracket (Fig. 14).
- Fit the gate into the guide bracket and fix the top hinge in place.
Attention:
To ensure trouble-free operation, do NOT weld the
gate to the guide bracket or to the bushing.
3.4 Installing the drive unit
- Prepare the drive unit for installation as follows:
· Remove the plastic cover from the rack ram (Fig. 15).
· Fit the release device (see chapter 6).
- Remove the cover plate from the foundation box (Fig. 16).
- Manually fit the gate at its half open position (angle α,
Fig. 17).
Attention:
Failure to fit the gate at the right angle will prevent
the gate from opening or closing fully on com-
pletion of the installation.
To determine the precise angle α, measure the length of line L
(Fig. 17) and position the gate at the mid-point of the line.
- Fit the drive unit inside the box and engage the rack ram with the
pinion in the box (Fig. 18).
Attention:
Fix the drive unit in place with the four M8 bolts
provided (Fig. 18). If possible, use a torque wrench
to tighten the bolts to 25,5 Nm.
- Release the drive unit (see chapter 6) and manually open the
leaf to check that the mechanism operates smoothly.
- Connect up the cables to the electronic control unit (see relevant
instructions).
