Notes of connections
To guarantee operator safety and to prevent damaging the components, never make connections or insert wireless receiver
boards while the control unit is powered. Power the control unit through a 3 x 1.5 mm
control unit and the ground system connection is more than 30 m, a ground plate must be installed in proximity to the control
unit.
If the motors do not have a cable, use the 4 x 1.5 mm
In connecting the part with an extremely low safety voltage, use cables with a minimum section of 0.5 or 0.75 mm
Use shielded cables if the length exceeds 30m and connecting the ground braid only from the side of the control unit.
Do not connect the cables in underground cases even if they are water-tight.
If they are not used, the inputs to the Normally Closed (NC) contacts must be jumpered to the common.
If the same input has more than one contact (NC), they are placed in series.
If they are not used, the inputs to the Normally Open (NO) contacts are left loose.
If the same input has more than one contact (NO), they are to be placed in series.
The contacts must be mechanical and free of any potential.
Remember that systems for automatic gates and doors must be installed by highly qualifi ed technicians only and in full
compliance with current law.

The TEST light signals that the internal logic is functioning correctly. It must flash at one second intervals indicating that the
internal microprocessor is on and awaiting a command. When the control unit is powered, the warning lights, set on the
inputs, are ON when the contacts on the inputs are closed toward the common:
Normally the red lights on inputs FCA-FCC-STOP-PHOTO-COAST, are ON
Normally the green lights on the control inputs OPEN-CLOSE-START-PEDESTRIAN are OFF
