D. INSTALLATION OF FRONT BRACKET
For proper operation, the front bracket should be fixed so the motor has the correct angle. Use Table 1 to
calculate the location of the front bracket. Also note that the front bracket is 50mm lower than the rear
bracket.

E. CHECK BRACKET
Secure the motor to the rear and front bracket as detailed in the Motor Fixing section.
Follow the instructions in the Emergency Release section to disengage the motor from the mechanics. You
should now be able to move the gate manually. Slowly fully open and close the gate manually. If the gate
fully opens and closes the installation of the brackets was done correctly.
INSTALLATION RULES
1. To prevent the operator from over running its maximum and minimum operating limits the operating
stroke,
Cu
(Cu= A + B) should always be shorter than the available stroke
CD
which is 350 mm.
2. To achieve 90˚ opening of a gate leaf
A + B = Cu
3. To achieve more than 90˚ opening of a gate leaf
A + B < Cu
4. The smaller the values for
A
and
B
the faster the gates will travel.
5. Limit the difference between
A
and
B
to less than 40 mm. Higher difference will vary the gate
opening and closing speed.
B
must always be greater than
F
when the gate leaf is in the closed position
