4.4 CHECKING THE FUNCTIONING
!
Warning
Make sure that the clutch screws on the geared motors are well tightened (about 8 Nm torque).
Information
The first control accepted by the machine when turned on or reset is the OPEN control regardless of the
position of the wings; any other control is ignored.
An impulse of "OPEN" type (man presence) allows opening the shutter for the time during which the control pushbutton
is held pressed down.
An impulse of "CLOSE" type (man presence) allows closing the shutter for the time during which the control pushbutton
is held pressed down.
A control opposite to the operation that the automatic operator is carrying out stops the motion.
To reset the proper functioning, release the operated controls and press only one of them.
When wings reach the maximum opening or closing position, motors stop due to electronic absorption.
When the mechanical clutch gets engaged before the electronic safety control, the geared motors stop at the
end of the FIXED AND NOT ADJUSTABLE operation time.
4.4.1 Obstacle detection
Information
The electronic control is equipped with an additional safety device for the " obstacle detection " with
independent wings.
An obstacle hindering the (opening or closing) motion of a wing for more than 3 seconds causes its stop,
whilst the other wing will complete the manoeuvre. To reset the normal functioning, it is recommended to
perform the opening manoeuvre completely.
Information
Gusts of wind or obstacles persisting/detected for less than 3 seconds do not make react the obstacle
detection device; under such conditions, the mechanical clutch is engaged.
