7.3 Adding Or Removing Devices - Nice Ten TN2010 Instructions Et Recommandations Pour L'installateur

7.2.6) Example of Level 2 programming (adjustable parameters)
This example shows the sequence of operations required to change the factory setting of the parameters and set the functions of the "Pause
Time" to 60s (input on L1 and level on L4) and "Speed" to L6 (input on L4 and level on L6).
Table 13: Example of LEVEL 2 programming
1. Press and hold [Set] for approx. 3s
2. Release the key [Set] when led L1 starts to flash
3. Press and hold [Set] during steps 4 and 5.
4. Wait approx. 3s until led L3 lights up, indicating the current level of "Pause Time"
5. Press the key [▼] once to move the illuminated led onto L3, indicating the new value of "Pause Time"
6. Release [Set]
7. Press [▼] twice to move the flashing led onto led L3
8. Press and hold [Set] during steps 9 and 10.
9. Wait approx. 3s until led L4 lights up, indicating the current level of "Motor speed"
10. Press the key [▼] twice to move the illuminated led onto L6, indicating the new value of "Motor speed"
11. Release [Set]
12. Wait 10s to exit the programming mode automatically after the maximum time interval
7.3) Adding or removing devices
Devices can be added or removed at any time on an automation using TEN. In particular the inputs "BlueBUS" and "STOP" can be con-
nected to various types of device as indicated in the paragraphs below.
After adding or removing devices, the device learning procedure must be repeated, as described in the paragraph "7.3.5 Learning other
devices".
7.3.1) BLUEBUS
BlueBUS is a technology that enables the connection of compatible devices with just two wires conveying the electric power and communi-
cation signals. All devices are connected in parallel on the same 2 BlueBUS wires, without the need to observe polarity; each devices is recog-
nised individually as it is assigned with an exclusive address during installation. BlueBUS can be used, for example, to connect the following:
photocells, safety devices, control pushbuttons, indicator lamps, etc. The TEN control unit recognises each one of the devices connected by
means of a specific self-learning phase and is able to detect all possible faults in maximum safety. For this reason each time a device is con-
nected to or removed from BlueBUS the self-learning phase must be repeated, as described in paragraph "7.3.5 Learning other devices".
7.3.2) STOP input
STOP is the input that causes immediate shutdown of movement
followed by a brief inversion of the manoeuvre This input can be con-
nected to devices with an output with NO normally open contacts,
NC normally closed contacts, OPTO SENSOR contacts or devices
with constant resistance 8.2KΩ output, such as sensitive edges. As
in the case of BlueBUS, the control unit recognises the type of
device connected to the STOP input during the self-learning phase
(see paragraph "7.3.5 Learning other devices"); after which a STOP
command is activated whenever a variation with respect to the
learned status is detected.
When set accordingly, more than one device can be connected to
the STOP input, also different from one another:
• Several NO devices can be connected in parallel with no limit to
number.
• Several NC devices can be connected in parallel with no limit to
number.
20
• Two devices with constant resistance 8.2KΩ can be connected in
parallel; if there are more than 2 devices then all must be con-
nected 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 the devices with a constant resistance
of 8,2KΩ or OPTO SENSOR optical devices guarantee
safety category 3 against faults in accordance with the
standard EN 954-1.
