TECHNICAL FEATURES
Power supply
The electric power is supplied to the electronic card and the motors by means of an electric transformer fitted with a protection fuse. The
appliance may be connected to an optional backup battery (12Vdc/ 7 Ah) for the automation system to work in case of absence of mains
power supply.
Radio Receiver
The electronic unit contains a two-channel radio receiver allowing remote control of the gate by means of the radio transmitter. The radio
receiver channel 1 acts as
Start
control and channel 2 acts as
Pedestrian start
. The radio receiver operates with a self-learning logic and
can store up to 50 different codes from the remote controls. Each code may be addressed on the desired channel (start or pedestrian start).
The memory content is preserved in absence of power supply. The memory contents may be erased (total cancellation). In alternative the
electronic unit is equipped for the optional connection of an accessory radio receiver card (J6 connector). 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.
Work Time
The motors’ work time is controlled by two independent digital timers. If any command interrupts the wing’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 for the wing to end its travel. For the automation system to work properly the work time value to be set must be slightly (approx.
5 sec.) above the wing’s actual work time. In this way the motor will stop even if the limit switch control has not operated. We recommend
to adjust the work time so that the wing starts to slow down at min. 50 cm. from the end of its travel. The stop of the wing depends by the
current consumed by the motor (Torque). During the normal speed phase, when the motor's current reaches the self-learned value, the
gate stops (both wings) in opening and then it reverses its motion for approx. 2 sec., while during the closure phase, the gate stops and
reverses its motion after approx. 1.5 sec. After the electric power is supplied to the electronic card (at installation), or after one absence of
power supply, when the Start push-button is pressed for the first time the gate performs an opening cycle.
Warning
: In case of absence of power supply the position of the gates will be lost (Timers reset) and the gates first command will perform
and opening manoeuvre.
Kickback / Extra-push
This procedure can be enabled or excluded. It is usually employed to help the electric lock insertion and release during bad weather
conditions (wind, etc.). The “
kickback
” procedure consists of a logic sequence operating the electric lock with a short closure phase
(approx 1 sec.) with the gate closed. The electric lock is released only after the wing has started its opening motion. The “
extra-push
”
procedure is enabled only during the closing slow-down phase near at the end of the wings’ travel. It consists of a short acceleration of
both wings (approx. 1 sec.) to help the electric lock’s insertion.
M1 delay at opening
The unit causes a fixed delay of approx. 2 seconds between the first wing’s (M2) and the second wing’s (M1) start during the gate’s
opening phase. This delay is imposed irrespective of the position from which the gate starts to open. This delay may be cancelled by
setting the
dip switch 5 =ON
.
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: signals the opening phase
Slow flashing light: signals the closing phase
Fixed light: 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 motors start (pre-alarm).
Important:
In case of absence of power supply, with the backup Battery connected to the card, the blinker flashes every 4 sec. (in opening
and closing cycle).
