LED - DL7
Led DL7, as well as the normal radio control programming signals, also indicates any errors with a
series of pre-set ashes:
5 ashes: no encoder signal;
Check wiring, check encoder by means of TEST-ENCODER (optional);
6 ashes: presence of obstacle (after 3 failed attempts at closure);
Ensure absence of obstacles along the door travel, and ensure smooth movement;
quick ashing: work time (stroke) SETUP procedure.
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 3 consecutive activations (during the same closing manoeuvre) of the encoder (ob-
stacle detection), the control unit opens completely 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 encoder.
MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
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;
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.
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);
