Position recovery mode

When you see both wings close at a slower rate than
usual and the flashing light is active in a different way
than usual (Also the two doors close one at a time, first
door 1 and then door 2), it means that the control unit
is retrieving the references: in this situation you have
to wait until the flashing has stopped to issue new
commands, as it is necessary to let the manoeuvre
finish. If you do not let the manoeuvre finish, the
movement of the wings will remain imprecise because
the correct references on the fully opening and closing
positions are not available. The only exception is
given by the motor with articulated arm if it uses
the opening limit switches: the activation of the limit
switch enables instant recovery of door position.
During the repositioning manoeuvre the flashing is
activated in a differentiated manner (3 seconds on,
1.5 seconds off) to highlight that this is a special
manoeuvring stage: only when the flashing returns
to normal will the control unit have recovered the
position references. The repositioning manoeuvre is
performed at low speeds, different from that set; in
the case where the set speed is very low, then the
repositioning is performed at that speed (without
further decreases).
The loss of references is caused by a blackout or
if the obstacle detection based on the current
consumed by the motor is active three times at
the sam point, thus indicating that there is a stable
obstacle on the road.

Battery operation mode

If the battery pack (B71/BCHP/EXT, Figure 8) is
installed, in the absence of mains voltage operation is
guaranteed by the 24Vdc-4500mAh backup batteries
mounted in a separate box.
For best performance it is recommended to power
the photocells (transmitter and receiver) and
possibly other devices that do not activate the
system (therefore excluding external radio receivers)
by connecting their positive terminals to the SC
terminal (Figure 7). Set the parameter
a804
if you want to also include the photo-test).
In this way, when the doors are fully open or fully
closed and the battery is delivering current, power
is cut to the devices connected to the SC terminal
The battery operation is shown on the display by the
Ba TT
message and by the occasional activation
of the flashing light (saving consumption). At the
drop of the battery voltage the speed of the doors
decreases When the battery voltage drops below
a minimum value for its integrity, the commands
given to the control panel are no longer performed,
and the display shows
the function is restored when the mains voltage
is back or in case of possible recovery of battery
power, during the forced inactivity. Even if the phase
shifts are disabled, at every movement command
executed under backup power, a phase shift equal to
1.5" is performed. If the power failure occurs during
the travel, a stop of engine can be generated, with
automatic resume of motion after a stabilization
break (2").

Extended operation mode

N.B.: if you are only using the simplified mode the
value of the invisible parameters - for a control
unit leaving the factory, or after a reset of the
standard parameters - this is the one shown next to
the parameter, and is considered to be of greater
usefulness in installations.
WARNING! Depending on the selected mode,
some parameters may not be displayed, as they do
not relate to the installation.
The table for the extended mode parameters is
below. The standard production value is next to the
parameter number.
