When LEDs DL7 and DL8 flash at the same time they indicate:

Multiple errors are signalled by a 2-second pause between signals.
Should the encoder (obstacle detection) activates while closing, the controller will reverse the direction
and slowly open until the laef reaches its fully opened position. Auto Close function will be deactivated
until a further command pulse is given. In case of 5 consecutive safety interventions the controller will
progressively increase the Auto Close delay. Once the closing has been succesfully achieved, the Auto
Close delay will go back to standard setting.
9. RESTORING AUTOMATIC OPERATION
Should the automation need to be operated manually, use the release system. After the manual op-
eration:
• after a Mains Power Failure, such as a black-out (controller remains disconnected for a certain time),
the automation will be moving slowly to allow the Controller to establish its Limits (REALIGNMENT
procedure);
• after a Manual Operation without Mains Power Failure (controller remains connected) it will take 4
to 5 complete cycles to complete the realignment procedure. During these cycles, Limits and Soft-
Stops will not be working.
10. 433.92 MHz BUILT-IN RADIO RECEIVER
The radio receiver can learn up to a maximum of 30 codes of rolling code (S2RP, S4RP, K-SLIM-RP, T-4RP)
to be set freely on 3 channels.
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 19 - 20, max. 24V AC, 1 A)
and the third channel controls directly the pedestrian opening from the controller.
LEARNING SYSTEM FOR RADIO CONTROL DEVICES
CH1 = 1 channel (OPEN/CLOSE)
st
1_ Press button CH1 briefly to associate a radio control device with the OPEN/CLOSE function;
2_ the (green) DL8 LED is ON to indicate the code learning mode has been activated (if no code is
entered within 10 seconds the board exits the programming function);
3_ press the button of the relative radio control device;
4_ the (green) DL8 LED turns off to indicate saving is complete and then on again immediately wait-
ing for other radio control devices (if this is not the case, try to re-transmit or wait 10 seconds and
restart from point 1);
5_ to memorise codes to other radio control devices, press the key to be stored on other devices
within 2-3 sec. After this time (DL8 LED turns off) must repeat the procedure from point 1 (up to a
maximum of 30 transmitters);
6_ if you wish to save on the 2nd channel, repeat the procedure from point 1 using the CH2 key instead
of CH1 (in this case the DL8 LED is yellow);
channel CH3 waiting to be saved;
CH3 channel memory full;
CH1 channel waiting to be cancelled;
cancelling of channel CH1 in progress;
CH2 channel waiting to be cancelled;
cancelling of channel CH2 in progress;
CH3 channel waiting to be cancelled;
cancelling of channel CH3 in progress;
factory reset procedure waiting for confirmation;
waiting for total cancellation of the radio channels;
CH2 = 2 channel
