D750M CHARACTERISTICS
LED - DL7
The LED, besides indicating that the radio controls are scheduled, also signals errors with a
series of pre-defined flashes:
steady light: normal operation;
2 flashes: phototest error;
Disable phototest (dip-switch 6 OFF), check operation and connection of photocells;
433.92 MHz BUILT-IN RADIO RECEIVER
The radio receiver can learn up to a maximum of 30 dip-switches (TXD2, TXD4, BUG2, BUG4,
SLIM, SLIM-C, T-4, T-4C) or rolling codes (BUG2R, BUG4R, SLIM-RP, T-4RP) which can be set
on the two channels as required.
The first channel directly commands the control board for opening the automatic device; the
second channel commands a relay for a N.O. no-voltage output contact (terminals 21 and 22,
max. 24 Vac, 1 A).
The learning mode (dip-switch or rolling code) is determined by the first radio control device and
remains unchanged until all the codes have been cancelled.
LEARNING SYSTEM FOR RADIO CONTROL DEVICES
P1 = OPEN/CLOSE
P2 = 2nd channel
1_ press button P1 briefly to associate a radio control device with the OPEN/CLOSE function;
2_ LED DL7 turns off to indicate that the code learning mode has been activated (if no code is
entered within 10 seconds, the board exits the programming mode);
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 hap-
pen, 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
maximum of 30 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.
Note: if the maximum number of radio control devices (30) is exceeded, LED DL7 flashes
rapidly for about 3 seconds without memorising the code.
If equipped with radio controls model T-4RP, SLIM-RP or BUG-R programmed by means of
TAUPROG, they can be memorised without using control unit keys P1 and P2. In this case refer
to the instructions of the specific radio control for the procedure for memorisation via radio.
REMOTE PROGRAMMING BY ROLLING CODE
It is possible to carry out the remote self-learning of the rolling code transmitters, that is without
pressing the receiver's programming button.
It will be sufficient to have an already programmed transmitter in the receiver in order to start the
procedure of remote programming of the new transmitters. Follow the procedure written on the
instructions of the rolling code transmitter.
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;
