Turn the screws clockwise to increase the
intensity of the deceleration.
Caution!
Reduce deceleration action to a
low setting if the system normally has to work
in ambient temperatures above 20 °C. This
avoids deceleration becoming too abrupt
when the temperature drops.
If the total angle of opening of the leaf is less
than 90°, the 760 operators model CR can
be set up so that deceleration is only active
on the closing cycle.
To ensure trouble-free operation, before you
fix the operator inside the foundation box,
move the leaf manually to a distance D from
its fully closed position:
D = L x 0.76 (fig. 23)
where L = leaf length.
See section 5.2 for details on how to set the
internal closed position travel stop adjusting
screws.
Adjustment of the internal open position
travel stop has no effect.
If the gate ever has to be operated manually
as a result of a power failure or malfunction,
release the gate with the key release device.
The release device, without the lock, is
supplied with the operator’s installation kit.
The key lock is available as an accessory in
two versions, with standard or numbered key.
See fig. 24 to fit the key lock to the release
device
