Connect Electrical Power Supply; Initial System Start-Up - Checks; Operating Test; Memorising Devices And Positions - Nice Soon Anweisungen

• Several NC devices can be connected in parallel with no limit to
number.
• Two devices with constant resistance 8,2KΩ 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 8,2KΩ.
• NO and NC combinations are possible by placing the 2 contacts
in parallel, taking care to place a 8,2KΩ resistance in parallel to the
NC contact (thus enabling the combination of 3 devices: NO, NC
and 8,2KΩ).
!
If the STOP input is used to connect devices with safe-
ty functions, only devices with the constant resistance
8,2KΩ output or OPTO SENSOR optical devices guarantee
safety class 3 against faults, according to standard EN
954-1.

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.

6) Initial system start-up - checks

!
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.

6.1) 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.

7) Memorising devices and positions

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).
For connection of an OPTO SENSOR type optical device, make con-
nections as shown in Fig. 9:

If none of these conditions occur, disconnect the power supply im-
mediately and check the electrical connections thoroughly.
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.
