DIP 9 ON = Slave Control Unit
DIP 9 OFF = Master Control Unit
NOTE: A variation of the dip-switches requires pressing the RESET
button on the control unit to activate the new setting.
NOTE: In applications requiring the use of a single control unit, make
sure it is always set as MASTER. Otherwise, the automation will not work.

DISABLING THE DS (SAFETY DEVICES)
Is it possible to disable the DS (Safety Devices) installed and connected
to the BUS line accessories, such as the photocells and the 8K2 input.
This allows the automation to operate even in case of suspected faults to
the DS, thus facilitating maintenance or technical checks of the system. In
any case, if the DS are disabled, only those that are actually faulty will be
excluded from the BUS, along with input 8K2, while the functional DS will
remain active.

DIP 10 ON = DS Disabled
DIP 10 OFF = DS Enabled
NOTE: Always enable the DSs, if present. Temporarily disable them only
during maintenance.
NOTE: A variation of the dip-switches requires pressing the RESET
button on the control unit to activate the new setting.
8K2 INPUT (STOP)
The control unit has a dedicated terminal for safety devices (DS) with an
8K2 impedance threshold. This input blocks (STOP) the automation if the

GND Common
ANTENNA INPUT
The control unit has a dedicated terminal to connect the radio antenna
needed to receive commands from 433 MHz radio transmitters (antenna
impedance: 50 Ohm).
Input terminal for radio antenna.
ANT Antenna Input (hot pole) impedance: 50 Ohm
GND Common (cold pole)
STROKE PROGRAMMING (AUTOSET))
The control unit allows Automatic Programming of the maximum gate
stroke.
CHECK OF OPERATOR ROTATION DIRECTION:
To speed up the stroke learning manoeuvre, it is advisable to check
whether the operator rotation direction (Operator 1) is consistent with the
expected movement of the gate. If the operator moves contrary to what
expected, press the RESET button, stopping the operator and change
THE ROTATION DIRECTION, without intervening physically on the electrical
connections (par. CHANGING THE OPERATOR ROTATION DIRECTION).
STROKE PROGRAMMING:
To start the self-learning procedure, position the gate half-open, press
the AUTOSET button until the respective LED lights up (positioned above
the AUTOSET button) and release the button. The AUTOSET led starts to
flash for a few seconds (detection of any accessories connected to the
BUS line), then the led remains lit and the operator starts the movement.
Operator 1 will run the closing movement until the gate reaches the limit
switch or limit stop.
The control unit completes the self-learning phase by performing a complete
opening and closing cycle (turning off the AUTOSET led).
The deceleration phase is set automatically during the self-learning cycle.
