4.3 CONNECTING OTHER DEVICES TO THE
CONTROL UNIT
If the user needs to power external devices, such as a proximity
reader for transponder cards or the light of the key selector
switch, power can be tapped as shown in the figure.
The power supply voltage is 24V

-30% ÷ +50% with a
maximum available current of 200mA.

The voltage available at the “SbS” and “STOP”
terminals remains even when the “Stand-by”
function is enabled on the board.
4.4 ADDRESSING OF DEVICES CONNECTED
WITH THE BLUEBUS SYSTEM
To allow the control unit to recognise the devices connected
through the “BlueBUS” system, these devices must be
addressed.
This operation can be carried out by correctly positioning
the electrical jumper present in each device (also refer to
the instruction manual of each device). Shown below is an
addressing diagram for photocells, based on their type.

CONFIGURATION NOT ALLOWED
m
At the end of the installation procedure, or after
photocells or other devices have been removed, it is
necessary to complete the learning procedure (see
the “Learning of connected devices” paragraph).
4.5 INITIAL START-UP AND ELECTRICAL
CONNECTIONS TEST
After powering the control unit on, carry out the following checks
(“ Figure 11 ”):
1. after a few seconds, check that the “Bluebus” ( A ) LED
flashes regularly with one flash per second
2. check that the LEDs of the photocells, both TX
(transmission) and RX (reception), flash. The type of flash
emitted in this phase is not significant
3. check that the warning light connected to the “Flash”
output is turned off.

If any one of these tests fails, disconnect the power
supply to the control unit and check the various
electrical connections made previously.
4.6 LEARNING OF CONNECTED DEVICES
After the initial start-up, the control unit must recognise the
devices connected to the “Bluebus” and “Stop” inputs.
l
The learning phase must be carried out even if no
device is connected to the control unit.
The control unit can individually recognise the various devices
connected, thanks to the learning procedure, and detect
possible anomalies.
For this to occur, the device learning procedure must be carried
out whenever a device is added or removed.
