* If using 24Vdc motors, replace the transformer provided with a
230/20 Vac transformer the power of which is suited to the type of
motor used (120W max; the outputs for the flashing light, electric
lock and photocell power supply will adapt to the voltage of 24Vdc,
but it is only ever possible to connect a 12Vdc battery, even when
using 24Vdc motors).

OPERATING CHARACTERISTICS:

Automatic:
Using either the radio control (CODE led lit) or the low tension button
panel (PUL) to operate the gates, commands will have the following
effect: the first command impulse activates the opening mechanism
either for the pre-set motor operating interval or until the activation of
the opening limit switch. The second command impulse closes the
gate. If a command impulse is received before the activation of the limit
switch the direction of movement of the mechanism will be reversed
whether engaged in opening or closing operations.
Step-by-step:
Using either the radio control (CODE led lit) or the low tension button
panel (PUL) to operate the gates, commands will have the following
effect: the first command impulse activates the opening mechanism

GB
the opening limit switch. The second command impulse closes the
gate. If a command impulse is received before the activation of the limit
switch the movement of the mechanism will be stopped. A further com-
mand impulse will reactivate the mechanism in the opposite direction.
Automatic closing:
The mechanism may be set up to automatically close the gate without
sending additional commands.
The set-up procedure is described in the instructions for setting the
delay period.
Pedestrian access:
Using the radio command (the CODE PED. led is on) or the button panel
(PED), you can activate just motor 1 for the programmed length of time
(T.MOT.PED. led).
Block input:
The control board allows for the connection of a blocking button (NC).
Commands from the button during any phase will immediately stop the
movement of the gate. A further command will only be executed if the
blocking mechanism is deactivated, and in any case normal automatic
opening will work.
If not used the terminals must be jumped.
Safety device:
The control board allows for the connection and control of photocells in
accordance with directive EN 12453.
Commands from the device during the opening phase will be ignored,
and when the gate is closing they will reverse the direction of move-
ment.
The control board needs the photocells to be connected to their respec-
tive dedicated inputs, otherwise it will not work.
AUX 1 safety device (PED input):
The control unit, when configured, can be fitted with an Auxiliary 1 safe-
ty device together with the Pedestrian Input (NC).
Commands from the device during the opening phase will stop the gate
temporarily; when reactivated, the control unit continues the opening
phase. Commands whilst the gate is closing will reverse the direction of
movement.
AUX 2 safety device (PED input):
The control unit, when configured, can be fitted with an Auxiliary 2 safe-
ty device together with the Pedestrian Input (NC).
Commands from the device during an opening or closing phase tem-
porarily reverse and then stop the movement.
Opening and closing limit switch:
The control unit permits the connection of an Opening and Closing limit
switch for each Motor (NC). Commands from the limit switches during
the respective work phases stop the respective motors immediately.
Warning: Connect the limit switches, if available; otherwise do not
jump the FA1, FC1, FA2 or FC2 inputs on the terminal board.
Initial pick-up and motor power adjustment:
The electronic control unit is equipped with a VR1 trimmer for initial
pick-up and motor power adjustment that are fully managed by the
microprocessor. Adjustment can be within a range of 50% to 100% of
max power.
Warning: you will need to repeat the teach-in phase if you wish to
adjust the VR1 trimmer as the operation and deceleration times
may be affected.
Obstacle detection:
The electronic control unit has a VR2 trimmer for adjusting the power
required to detect obstacles. You can control this entirely from the
microprocessor.
The trimmer's activation time can be set between a minimum of 0.1 sec-
onds and a maximum of 3 seconds.
Warning:
- When limit switches are connected to the control unit, the detection of
an obstacle causes the motor to change direction during the closing
phase and reverse for 2 seconds during the opening phase.
- When no limit switches are connected to the control unit, the detec-
tion of an obstacle always causes the motor to change direction during
the closing phase (and then take 5 seconds to close) and reverse for 2
seconds during the opening phase (and then take 5 seconds to stop).
Deceleration:
The motor deceleration function is used to avoid the gates moving at
high speed towards the end of the opening and closing stages.
Deceleration can be programmed for the desired points (before the
gates are totally open or closed) during Motor Timer programming.
