5.4) Connect electrical power supply
For electrical power supply of SOON, simply insert the plug in a mains socket. If necessary, use a commercially available adapter if the SOON
plug does not correspond to the mains socket available.
• Several NC devices can be connected in parallel with no limit to
number.
• Two devices with constant resistance 8,2K
!
can be connected in
parallel; if there are more than 2 devices then all must be connect-
ed in cascade, with a single terminating resistance of 8,2K
!
.
• NO and NC combinations are possible by placing the 2 contacts
in parallel, taking care to place a 8,2K
!
resistance in parallel to the
NC contact (thus enabling the combination of 3 devices: NO, NC
and 8,2K
!
).
If the STOP input is used to connect devices with safe-
ty functions, only devices with the constant resistance
8,2K
!
output or OPTO SENSOR optical devices guarantee
safety class 3 against faults, according to standard EN
954-1.
For connection of an OPTO SENSOR type optical device, make con-
nections as shown in Fig. 9:

The following operations will be performed on live electrical circuits and therefore manoeuvres may be hazardous!
Therefore take great care and never perform operations alone.
On completion of component installation and electrical connections, a number of simple checks must be made to ensure correct operation
of the system operation, before proceeding. Perform the following operations as specified and cross off the points as conformity of results is
verified.
!
6) Initial system start-up - checks
7) Memorising devices and positions
6.1) Operating test
As soon as SOON is powered up, proceed as follows:
K
Check that the BlueBUS led flashes regularly at the frequency of
one flash per second.
K
If photocells are present, ensure that the relative leds are also
flashing (both on TX and RX); the type of flash is not significant,
as this depends on other factors.
K
Check that the device connected to the FLASH output is off.
K
Check that the courtesy light is off.
If none of these conditions occur, disconnect the power supply im-
mediately and check the electrical connections thoroughly.
7.1) Memorising devices
After connecting to the power supply, the control unit must recog-
nise the devices connected to the inputs BlueBUS and STOP Be-
fore this phase, leds L1 and L2 flash to indicate that the device self-
learning process must be performed.
The device self-learning phase must be performed
even if no device is connected
1. Press and hold keys

and
[Set]
2. Release the keys when leds L1 and L2 start to flash quickly (after
around 3s)
3. Wait a few seconds for the control unit to finish device self-learn-
ing.
At the end of the self-learning process, the STOP led must remain lit,
while leds L1 and L2 turn off (where relevant leds L3 and L4 start
flashing).
The phase of self-learning the devices connected can be repeated
at any time also after installation, such as in the case that a device is
added.
