24 Vdc CONTROL UNIT FOR SLIDING GATES
OPERATING INSTRUCTIONS – INSTALLATION INSTRUCTIONS
1. GENERAL CHARACTERISTICS
This 24Vdc control unit for sliding gates offers high performance and a wide range of adjustments, with opening and
closing slow-downs, encoder management and the possibility of managing both opening and closing travel limit
devices.
If correctly installed, thanks to encoder control, this control unit guarantees installation conforming to current safety
regulations.
A sophisticated electronic control monitors the power circuit at all times and disables the control unit in the event of
malfunctions that could impair efficiency of the electronic clutch.
The parameter settings and the operating logics are shown on a handy LCD display, which indicates gate status during
normal operation. Operating times are controlled by self-learning during programming.
In “C” version gearmotors, the control unit is on board the gearmotor. A waterproof enclosure is available for housing
the control unit and any buffer batteries (optional) which must correspond to the indications in the following table.

Different output values can be obtained on the 24Vac output depending on the mains voltage value. Before
start-up, always check the transformer output voltage. It must not exceed 26Vac for both power feed values of
230Vac and 115Vac. Voltage must be measured load free, i.e. with the transformer powered and disconnected
from the board.
3. PREPARATIONS
To ensure people’s safety, all warnings and instructions in this booklet must be carefully observed. Incorrect
installation or incorrect use of the product could cause serious harm to people.
Keep the instructions for future reference
Make sure there is an adequate differential switch upstream of the system as specified by current laws, and install a
single-pole thermal breaker on the electrical power mains.
To lay cables, use adequate rigid and/or flexible tubes.
Always separate connection cables of low voltage accessories from those supplying 115/230 Vac. To prevent any
interference whatever, use separate sheaths.
If you wish to put the control unit in a remote position with respect to the motor, the maximum length of the
power cables between the control unit and the motor must not exceed 3 m, using cables with a diameter
of 2.5 mm
2
for the motor and 3x0.5 mm
2
for the encoder and the travel limit devices (optionals). One cannot
guarantee correct encoder operation for distances longer than 3 meters.
Procedure for securing components inside the water-tight enclosure, refer to paragraph 15.
