ENGLISH
Radioreceiver
The electronic unit is pre-set for the optional connection of an accessory radio receiver card allowing remote control of the gate by means of the radio
transmitter. The channel 1 of the radio receiver card ends with a non-polarized electric contact (relay) directly connected to the start input. The
channel 2 of the radio receiver card ends with a non-polarized electric contact (relay) directly connected to the 2nd radio channel output.
Blinker
The electronic card supplies an on/off control (flashing light) to the lamp. The logic of the blinking allows displaying the gate's operating.
Quick flashing light : it signals the opening phase.
Slow flashing light : it signals the closing phase.
Fixed light : it signals that the gate is blocked in pause before the closure phase in "automatic" mode.
The device supplies an on/off control (fixed light) to the lamp for approx. 1,5 sec. before the motor start (pre-alarm).
Work time
The motor's work time is controlled by one digital timer. For the automation system to work properly the operating time value to be set must be slightly
(min. 2 sec.) above the gate's actual work time. Warning : The following precaution will protect the motor in case of limit switch failure.
If any command interrupts the gate's travel before its end, the Timer stops and the elapsed time is stored in memory. Therefore the unit can determine,
with a fair approximation, the partial working time necessary to the gate to end its travel. In case of limit switch lack, thanks to this feature it is possible
to avoid that the motor works for a long time after the end of the gate's travel, thus reducing overheating to the minimum.
Warning : In case of absence of power supply the stored position will be lost.
Immediate closing
This procedure can be enabled or excluded. It is usually employed when the gate must close as soon as the vehicle has passed the optical barrier
(photo-cell) placed along the way.
Caution: This procedure must be excluded in the "condominium" mode.
Traffic Light Card
With just a few electric cables the unit can be connected to an electronic card that controls a two-colour (red and green) traffic light. The traffic light
operates in the following way :
1) Lights off when the gate is closed
2) Red light on when the gate moves
3) Green light on when the gate is open
