3_ press the button of the relative radio control device;
4_ LED DL7 turns on again to indicate that the code has been memorised (if this does not happen,
wait 10 seconds and start again from point 1);
5_ to memorise codes to other radio control devices, repeat the procedure from point 1 up to a maxi-
mum of 8 transmitters;
6_ to memorise codes on the 2nd channel, repeat the procedure from point 1 using button P2 instead
of P1;
7_ to exit the learning mode without memorising a code, press button P1 or P2 briefly.
N.B.: if the maximum number of codes (8) is exceeded, LED DL8 flashes rapidly for about 3
seconds without memorising the code.
CANCELLING CODES FROM RADIO CONTROL DEVICES
1_ keep button P1 pressed for 3 seconds in order to cancel all the associated radio control devices;
2_ LED DL7 flashes slowly to indicate that the cancellation mode has been activated;
3_ press button P1 again for 3 seconds;
4_ LED DL7 turns off for approx. 3 seconds and then remains steady to indicate that the code has
been cancelled;
5_ repeat the procedure from point 1 using button P2 to cancel all the associated radio control de-
vices;
6_ to exit the learning mode without memorising a code, press button P1 or P2 briefly.
ATTENTION: TO memorise a code on a new type of remote control unit (e.g.: from dip-switch
to rolling code or vice-versa) both channels must be cancelled.
LED - DL7
Led DL7, as well as the normal radio control programming signals, also indicates any errors with a
series of pre-set flashes:
• 5 flashes:
Check wiring, check encoder by means of TEST-ENCODER (optional);
• 6 flashes:
Ensure absence of obstacles along the door travel, and ensure smooth movement;
• quick flashing:
The display of multiple errors is shown with a pause of 2 seconds between one message and the
next. The error remains on display until a new complete manoeuvre (open and close) is performed
by the automation.
In the event of 5 consecutive activations (during the same opening or closing manoeuvre) of the
safety systems, the control unit runs a search for the closing end stop on the next manoeuvre. To
reset, the automation must complete a manoeuvre (opening and then closing); otherwise the end stop
search process will be repeated after each activation of the safety devices.
MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
1_ The automation does not start
a_ Check there is 230Vac power supply with the multimeter;
b_ Check that the NC contacts of the card are actually normally closed (6 green LEDs on);
c_ Check that the fuses are intact with the multimeter;
2_ The radio control has very little range
a_ Connect the radio aerial to the terminals of the receiver card and not to terminals 7-8 of the
control card (for frequency 433,92 MHz);
b_ Check that the ground and the aerial signal connections have not been inverted;
c_ Do not make joints to increase the length of the aerial wire;
d_ Do not install the aerial in a low position or behind walls or pillars;
e_ Check the state of the radio control batteries.
3_ The motors function in reverse
a_ Invert the motor connections on the terminal block (terminals 19 and 21 for motor 1; terminals
22 and 24 for motor 2);
no encoder signal;
presence of obstacle (after 5 failed attempts at closure);
work time (stroke) SETUP procedure.
