3.4 - Installation preparation works
In fig.1 is an example of an automation system using King-Gates
components. These components are positioned following a typical
and standard setup.
With reference to fig.1, define the approximate installation position
of each system component and the most appropriate connection
setup.

3.5 - Installation of the fixing brackets
and the gearmotor
3.5.1 – Installation of the rear fixing
bracket
Calculate the rear bracket position using chart 1.
This chart is used to define distances A and E and the maximum
opening angle of the gate leaf. Important - Distances A and E
must be similar, to ensure a linear automation movement.
We suggest that the values inside the recommended installation area
are used; only consider the maximum installation area if staying within
the recommended values is not possible.

Useful components for a complete system:
1 - Electromechanical gearmotors
2 - Pair of photocells
3 - Pair of stops (open position)
4 - Photocell columns
5 - Flashing warning device with built-in antenna
6 - Key selector or digital keypad
7 - Vertical solenoid latch

01. Measure value E , and then trace a straight horizontal line by
that value. Select a point in the line, taking into account the desired
opening angle, suitable for the column. Trace a straight vertical line
starting from the identified point, and obtain value A. Before proceed-
ing with the installation, make sure that value A allows to fix the rear
bracket, otherwise select another point on the chart. Lastly, to fix the
bracket move the piston to the limit of the stroke (see Fig. 2).
Failure to comply with the bracket installation distances may lead to
automation operation faults, such as:
- Cyclical movements and accelerations at some positions of the
stroke.
- Increased motor noise.
- Limited opening, or no opening at all (in case of counter-lever fixed
motor).
02. Before it can be fixed to the wall, the bracket must be welded
to the fastening plate (Fig. 3); the bracket may be cut to the desired
length, adjusting distances A and E accordingly.
Note - The bracket supplied with the gearmotor is 180 mm long
–
WARNING! Before fixing the rear bracket, make sure that
the front bracket will be fixed to a solid position of the gate
leaf; the front bracket will have to be secured at a different
height than the rear bracket (Fig. 4).
