CLUTCH ADJUSTMENT
ATTENTION
The adjustment of the clutch and all the safety devices must be per-
formed only by qualified personnel.
The ONDA 500 / ONDA 800 is fitted with an mechanical clutch in accordance
with the safety regulations for automatic devices. The clutch intervenes by
limiting the pressure of the gate on any obstacle in its path.
ATTENTION
•
The calibration value must be established on the site once installa-
tion has taken place, and must comply with the existing Safety
Regulations (15 daN).
•
If the max valve is exceeded, it is necessary to increase the number
of safety devices, in accordance with the existing safety regulations.
•
Check the thrust force in both directions and at different gate
positions.
To do this:
-
Turn OFF the mains supply to geared-motor.
-
Remove the cover from the geared-motor.
-
Hold the screw (D7
➀
) firm with an hexagonal key (CH 4), and adjust the
nut (D7
➁
) with a fixed spanner (CH 13); SCREW DOWN to increase
pressure, UNSCREW to reduce it.
-
Start up the geared-motor and check the gate thrust with a DYNAMOM-
ETER (D8
➂
).
-
Repeat the above operations until the correct thrust pressures are
obtained for the different opening positions.
CLOSING THE GEARED-MOTOR
Close the geared-motor with its cover.
Be careful to insert the cover in its special guides (D9) and don’t damage
the electric cables when closing.
