iS250/iS250D/iS250Solar SWING GATE OPENER MANUAL
E. CHECK BRACKET
Secure the motor to the rear bracket firmly as detailed in the Motor Fixing section.
Follow the instructions in the Emergency Release section to disengage the motor from the mechanics.
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 545 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
F. MOTOR FIXING
1. Attached the front bracket to the operator only.
2. Fully close the gate and move the motor piston to the maximum extended position.
3. Then move the front bracket (attached to the motor piston) back by 10mm. Mark the position of the bracket
on the gate.
4. Move the gate and the motor piston into the fully open position. The bracket should correspond to the
same marking on the gate. If it does not please recalculate A and B dimensions.
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.
Make sure the iS250 is mounted in a horizontal position, especially in these positions:
1) Gate in “CLOSE” position
2) Gate in “OPEN” position
3) Gate at “45° angle” position
Prior to welding the bracket on the gate leaf (if necessary), cover the gate opener to prevent
damages from sparks.
