INSTALLATION
Clutch regulation (KM1800 and KM2500)

Installation Guide
The operator has an adjustable mechanical clutch in
order to limit the maximum torque (maximum gate
thrust).
 The correct adjustment of the clutch is of vital
importance for the gate to stop when coming
across a possible obstacle, without producing
any injury or damage. Increased torque
produces a more violent impact.
Regulate the clutch at the minimum value possible,
compatible with the proper operation of the gate. To
do this:
1 Introduce the Allen key (1) in the adjustment
housing (2).
2 Turn the key until the notches of the frame (3) and
the housing (4) coincide.
3 Introduce a screwdriver in the resulting notch in
order to prevent the transmission tree from turning.
4 Turn the key clockwise to increase the clutch
transmission force, or anti-clockwise to reduce it.

KM1800 Operator: regulate the PM potentiometer
to the maximum (see"Potentiometer adjustment"
on page 74).

KM2500 Operator: if a control board with torque
adjustment is used, set it to the maximum level.
