9.2 DETECTING ICE ON THE GUIDES AND FITTED BOLTS DURING THE ROLLING SHUTTER RISE
The T-MODE motor with electronic travel limit is able to detect possible
bolts fitted in the rolling shutter as well as the presence of ice on the
guides during the whole travel of the rolling shutter.
These events would
prevent the normal rise of the rolling shutter thus damaging it.
When the rolling shutter is at rest, if you send a rise signal, and the rolling
shutter stays at rest for 1 second due to the presence of bolts or ice on
the guides, the motor changes to stop status.
9.2.1 INCREASING ICE AND FITTED BOLS DETECTION SENSITIVITY
You can increase the detection sensitivity of fitted bolts or ice in an area between the down travel limit and a
chosen point.
In this area, if the presence of ice or bolts is detected, the motor response time is of 0.2 seconds.
When the motor detects the presence of ice or bolts, it returns to the stop status and, to open the rolling shutter, you
must send a down command.
You can also join a torque reduction (see charter 9.1) to the sensitivity increase.
HIGH SENSITIVITY AREA
(Power to the motor is cut after the rolling shutter has been blocked for 0.2 seconds)
Down
travel limit
Up
travel limit
STANDARD SENSITIVITY AREA
(Power to the motor is cut after the rolling shutter has been blocked for 1 second)
THE HIGH SENSITIVITY AREA IS SET STARTING FROM THE DOWN TRAVEL LIMIT UP TO THE SELECTED POINT, AS DESCRIBED IN THE
PROCEDURE BELOW
Take the rolling shutter to
the point where you require
a high sensitivity.
Press the programming push-button four times (every pressing should last 2 s
and the interval between two pressings should be of approx. 1 second)
9.2.1.1 SETTING THE HIGH SENSITIVITY AREA
every pressing
2 seconds
1) Take the rolling shutter up to the point where you require a higher sensitivity during detection of bolts or ice on the
guides (You can also set the whole rolling shutter travel)
2) Press the programming push-button four times
3) The motor performs three brief movements to confirm you have entered the advanced menu
4) Press twice the STOP /PREFERRED POSITION push-button, then press it again and hold it down until the motor performs
2 brief movements in both directions to confirm the setting of the position and the exit from the advanced menu.
6) If the motor performs three brief movements in both directions, this means that the procedure was not performed
correctly and that you are still in the advanced menu. Repeat point 4.
