"Obstacle Detection" Function - Nice Era Mat A Instrucciones Y Advertencias De Instalación Y Uso

04. Keep the s and n keys pressed simultaneously and wait for the motor to perform 2 movements. Upon completion, release the keys.
05. Then select the behaviour that you want to assign to the motor:
• After the edge intervention, the motor continues to descend until reaching the memorized limit switch (keys).
• After the edge intervention the motor stops and does not perform the brief conversion of motion (key n).
• After the edge intervention, the motor stops and the system moves the position of the limit switch "1", placing it right before the edge intervention position (note - a
few manoeuvres to set the optimal bout you may be required) (key t).
Then she the key combined with the selected behaviour pressed and wait for the motor to perform 3 movements. Upon completion, release the key.

Notes:
– When performing the procedure, at any time you can cancel it by keeping the n and t keys pressed simultaneously for 4 seconds. Otherwise, do not press any key and
wait 60 seconds for the motor to perform 6 movements.
– To delete the setting you have selected and reconfigure the input for a climate sensor, you must delete the positions of limit switches "0" and "1" (paragraph 5.13).
7 WARNINGS FOR DAILY USE
OF THE AUTOMATION

7.1 - "Obstacle detection" function

The "obstacle detection" function described in Chapter 2 is activated automatically
when programming the limit switches. Subsequently it is possible to adjust the sen-
sitivity to the obstacle (paragraph 5.12), or the force that a motor must exert against
the obstacle to free the shutter.
If this function blocks in the movement of the shutter frequently, for no good reason,
it is recommended to deactivate the function (paragraph 5.12).
7.2 - Maximum continuous work cycle
In general the motors of the "Era" line were designed for residential use and therefore
for discontinuous use. for a guarantee a maximum operation time of four minutes
and in cases of overheating (e.g. caused by continuous prolonged operation) a "ther-
mal protector" for safety intervenes to cut out the power supply and reset kits when
the temperature returns to normal.
7.3 - "Limit switch self-update" function
The limit switches adjusted by the impact of the mechanical blocks (safety plugs and
a rigid anti-intrusion springs) are verified by the "limit switch self -update" function
every time the shutter performs a manoeuvre and bumps into its limit switch. this al-
lows the function of measuring the new limit switch values and updating the existing
ones, thereby recovering any slack that may have occurred throughout time due to
wear and/or thermal shock to which the slats and motor springs are subjected. the
constant update of the heights allows the rolling shutter to always reach the limit
switch with maximum precision.
This function is not activated when the stroke of the shutter lasts for less than 2.5
seconds and does not reach the limit switch.
7.4 - Commanding partial opening/closing of
shutter ("H" height)
In general, to command the partial opening/closing of the shutter, press the key as-
sociated with the partial height during programming (for more information, read point
06 of procedure 5.9). If the transmitter has only three keys and only one "H" height is
memorized, simultaneously press keys s and t to recall this height.

(troubleshooting guide)
q Powering an electrical phase, the motor does not move:
After excluding the possibility that thermal protection is active, in which case it is
sufficient to wait for the motor to cool down, make sure the mains voltage corre-
sponds to the values indicated on rating plate of motor.
q When sending a Raise command, the motor does not start:
This can happen if the shutter is near the Upper limit switch ("0"). In this case you
must lower the shutter a short bit and give the Raise command again.
q The system operates in the emergency condition with an operator present:
– Check to see if the motor has undergone a significant thermal or mechanical
shock.
– Make sure each part of the motor is still in good condition.
– Perform the deletion procedure (paragraph 5.13) and adjust the limit switches
again.
q Involuntary stopping of shutter motion (false obstacle):
After sending the command to the shutter, if the shutter stops during the stroke
at a certain point for no good reason (slight friction), it is recommended to:
– adjust the level of sensitivity to the obstacle (paragraph 5.12), by increasing the
force. If this does not solve the problem,
– adjust the limit switches with the manual procedure (paragraph 5.6) and set the
sensitivity level (paragraph 5.12) to level 4 (= sensitivity deactivated).
