7.2.6) Level two programming example (adjustable parameters)
The sequence to follow in order to change the factory settings of the parameters increasing the “Pause Time” to 60 seconds (input on L1
and level on L5), and lowering the “Motor Force” for light gates (input on L5 and level on L2) have been included as examples.
1. Press the key [Set] and hold it down (approx. 3 s)
3s
2. Release the [Set] key when L1 LED starts flashing
L1
3. Press the key [Set] and hold it down during step 4 and 5
4. Wait approx. 3 seconds until LED L3, which represents the current level of the “Pause time”,
switches on.
L3 3s
5. Press the [

] key twice to move the LED which is lit on to L5, which represents the
new “Pause Time” value. L5
6. Release the key [Set]
7. Press the [

8. Press the key [Set] and hold it down during step 9 and 10
9. Wait approx. 3 seconds until LED L5, which represents the current level
of the “Motor Force”, switches on.

new “Motor Force” value. L2
11. Release the key [Set]
12. Wait 10 seconds before leaving the programme to allow the maximum time to lapse.

7.3) Adding or Removing Devices
Devices can be added to or removed from the ROBUS350 automa-
tion system at any time. In particular, various devices types can be
connected to “BLUEBUS” and “STOP” input as explained in paragraphs “7.3.1 BlueBUS” and “7.3.2 STOP Input”.
7.3.1) BlueBUS
BlueBUS technology allows you to connect compatible devices
using only two wires which carry both the power supply and the
communication signals. All the devices are connected in parallel on
the 2 wires of the BlueBUS itself. It is not necessary to observe any
polarity; each device is individually recognized because a univocal
address is assigned to it during the installation. Photocells, safety
devices, control keys, signalling lights etc. can be connected to
BlueBUS The ROBUS350 control unit recognizes all the connect-
ed devices individually through a suitable recognition process, and can detect all the possible abnormalities with absolute precision
For this reason, each time a device connected to BlueBUS is added
or removed the control unit must go through the recognition
process; see paragraph 7.2.4 “Recognition of Other Devices”.
7.3.2) STOP Input
STOP is the input that causes the immediate interruption of the
manoeuvre (with a short reverse run). Devices with output featuring
normally open “NO” contacts and devices with normally closed
“NC” contacts, as well as devices with 8.2K
Ω
constant resistance
output, like sensitive edges, can be connected to this input.
During the recognition stage the control unit, like BlueBUS, recog-
nizes the type of device connected to the STOP input (see para-
graph 7.2.4 “Recognition of Other Devices”); subsequently it com-
mands a STOP whenever a change occurs in the recognized status.
Multiple devices, even of different type, can be connected to the
STOP input if suitable arrangements are made.
• Any number of NO devices can be connected to each other in
parallel.
• Any number of NC devices can be connected to each other in
series.
• Two devices with 8.2K
Ω
constant resistance output can be con-
nected in parallel; if needed, multiple devices must be connected
“in cascade” with a single 8.2K
Ω
termination resistance
• It is possible to combine Normally Open and Normally Closed by
making 2 contacts in parallel with the warning to place an 8.2 K
Ω
resistance in series with the Normally Closed contact (this also
makes it possible to combine 3 devices: Normally Open, Normal-
ly Closed and 8.2 K
Ω
).
if the STOP input is used to connect devices with safe-
ty functions, only the devices with 8.2K
Ω
constant resis-
tance output guarantee the fail-safe category 3 according
to EN standard 954-1.
