WARNINGS FOR ORDINARY USE
OF THE MECHANISM
6.1 - Maximum continuous work cycle
In general, the motors in the "Era" line were designed for residential use and there-
fore for discontinuous use. They guarantee a maximum operating time of 4 min-
utes and in cases of overheating (e.g. caused by continuous prolonged operation)
a "thermal protector" for safety intervenes to cut out the power supply, restoring it
when the temperature returns to normal.
6.2 - "Automatic limit switch update"
function
The limit switches adjusted through the impact of the box against the structure or
other mechanical blocks are verified by the "Automatic limit switch update" function
every time the awning performs a maneuver and bumps into its limit switches. This
allows the function to measure the new limit switch values and update the existing
ones, thereby recovering any slack that may have occurred throughout time due to
wear and/or thermal shocks to which the parts of the structure are subjected. The
constant update of the heights allows the awning to always reach the limit switch
with maximum precision.
This function is not activated when the stroke of the awning lasts for less than 2.5
seconds and does not reach the limit switch.
6.3 - Commanding partial opening/closing of the
awning (height "H")
In general, to command the partial opening/closing of the awning, press the key
associated 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 memorised, simultaneously press keys s and t to recall this height.
What to do if...
(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 cor-
responds to the values indicated in the technical characteristics of this manual
by measuring the electricity between the "common" wire and the electrical phase
wire supplied with current. Finally, try to supply the opposite electrical phase.
q When sending a Raise command, the motor does not start:
This can happen if the awning is near the Upper limit switch ("0"). In this case you
must lower the awning a little 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 5.16) and adjust the limit switches
again.
