11) Technical features

Power regulator
Regulating the RV1 trimmer it is possible reduce the power supplied to the motor during the normal speed phase.
Caution: In case failure or anomaly of the electronic card the motor may operate at its maximum power value. This is why n° 7 note in the
previous chapter "limits to use" must absolutely be put into practice.
Starting of maximum start up power
When the motor starts the unit supplies the maximum power value for approx. 1 sec. Subsequently the power regulator operates. This particular
feature allows to overcome the high negative torque at the motor's start.
Radioreceiver
The electronic unit contains a two-channel radio receiver allowing remote control of the gate by means of the radio transmitter. When dip-switch 4=ON
the radio receiver channel 1 acts as Start control and channel 2 acts as Pedestrian start. When dip switch 4=OFF the radio receiver channel 1 acts
as Opening start, whereas channel 2 acts as Closing start. The radio receiver operates with a self-learning logic and can store up to 50 codes. Each
code may be addressed on the desired channel. The memory contents is preserved in absence of power supply . The memory contents may be erased
(total cancellation). In alternative the electronic unit is pre-set for the optional connection of an accessory radio receiver card. The channel 1 of the
radio receiver card ends with a non-polarized electric contact (relay) directly connected to the start / opening start input. The channel 2 of the radio
receiver card ends with a non-polarized electric contact (relay) directly connected to the pedestrian start / closing start input.
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 wait that the obstacle that covers the photocell or photostop to be removed.
The device supplies an ON / OFF control (flashing light) to the lamp for approx. 1 sec. before the motor start (pre-alarm).
Work time
The motor's work time is controlled by one digital timer. 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.
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.
