If engines remain immobile in a completely open or completely closed position for more
than an hour, they are enabled in direction of strike until reaching the end run level, or for
3 seconds. This operation takes place once every hour.
N.B.: This function has the purpose of compensating any oil volume decrease in the hydraulic
motors, due to a temperature drop during prolonged pauses, for instance at night, or to
internal leaks.
IMPORTANT - When no adequate mechanical backstops are installed, do not use this
function.
OFF: Excludes the said function.
Hold-to-run operation: the manoeuvre continues as long as the command key is kept pressed.
It is not possible to use the radio transmitter.
Impulse operation: one impulse opens the gate if closed, and closes it if open.
In case of obscuring, this excludes photocell operation on opening. During the closing phase, it
immediately reverses the motion.
In case of obscuring, the photocells are active both on opening and on closing. When a photo-
cell is obscured on closing, it reverses the motion only after the photocell is disengaged.
Closes 3s after the photocells are cleared before waiting for the set TCA to elapse.

The control panel is set as Master in a centralised connection.
The control panel is set as Slave in a centralised connection.
The receiver is con gured for operation in xed-code mode, see paragraph on "Radio
Transmitter Cloning".
The receiver is con gured for operation in rolling-code mode, see paragraph on "Radio
Transmitter Cloning".
This enables transmitter storage via radio:
1 – First press the hidden key and then the normal key (T1, T2, T3 or T4) of a transmitter
already memorised in standard mode by means of the radio menu.
2 – Within 10s press the hidden key and the normal key (T1, T2, T3 or T4) of a transmitter
to be memorised.
The receiver exits the programming mode after 10s, other new transmitters can be entered
before the end of this time.
This mode does not require access to the control panel.
This disables transmitter storage via radio.
The transmitters can only be memorised using the appropriate Radio menu.
Only motor 2 activated (1 leaf ).
Both motors are activated (2 leaves).
The output between terminals 21 and 22 is con gured as Gate-open warning light, in this case
the 2nd radio channel controls pedestrian opening.
The output between terminals 21 and 22 is con gured as 2nd radio channel.
To be used when a closing backstop is present.
This function activates leaf pressure on the backstop, without this being considered as an
obstacle by the ampere-stop sensor.
Therefore the rod continues its stroke for another 0.5s, after intercepting the closing limit
switch or as far as the backstop. This way, by slightly anticipating closing limit switch acti-
vation, the leaves will come to a perfect halt against the end stop plates (Fig. I Rif. A).
Movement is exclusively stopped by closing limit switch activation, in this case you must
proceed to a precise setting of closing limit switch activation (Fig. I Rif. B).
Flashing is switched on when movement starts (duration 3s).
Flashing is switched o when movement starts.
Red lights switched on when gate closed.
Lights switched o if gate closed.
