The unit does not respond to the
instructions sent by the supervision
PC on the CCN bus.
Problem at the RS485 converter
level of the PC or connection
problem on the primary CCN bus.
Check the CCN cable connections.
The unit CCN address is 0.1 and
the communication speed is 9600
baud by default.
Replace the RS485 connector.
Communication problem when
connecting two buses (primary bus
and secondary bus).
Electrical problem between 0 V
CCN of the primary bus and 0 V
CCN of the secondary bus.
Check the connection of the metal
part of the interface casing to earth.
Connect the metal part of the interface casing to earth.

Loading of the start-up page, then
fault.
Network property details are not
valid, Ethernet network is not
available.
Check the network parameters.
Check for ashing of the orange
LED on the unit.
Contact your system administrator. Check the Ethernet
connection to the local network if the orange LED does not
ash.
While accessing the unit via the
web browser, the Java platform
launches, but remains blocked. No
le is loaded.
Proxy server problem in the local
network.
Contact your system administrator. In agreement with your system administrator open the
Runtime Java control panel and select "direct connection" in
the system parameters and/or request in the web browser
(Tools -> Options -> Connection -> System parameters) that
no proxy server is used to go to the local addresses. If
possible untick "use of an automatic conguration script".
Restart the web browser.
The application has been launched,
but the screens are not shown in the
web browser.
A proxy server is used to access the
unit and this supplies the old
screens to the browser. Incorrect
conguration of the Java
application.
Check that the web browser does
not go via a proxy server to access
the unit. Check that the Java
application does not store the
internet les on the PC.
Open the browser and in the system connection parameters
add the IP address of the unit in the proxy exceptions. (Tools
-> Options -> Connection -> System parameters -> "No
proxy for"). See chapter 8.3.4.

8.3.1 - The Unit is Point-to-point Connected to A PC
Make sure the controller is powered on before conguration.
Check Ethernet connection if necessary, and the PC NIC
conguration (see also 8.3.3).
Click on the “Properties” button of the internet protocol.
• If no IP address is congured in the “General” and
“Alternative conguration” tabs, the unit IP address
must be congured to 169.254.xxx.xxx. Modify the unit
IP address and then restart the system.
• If the PC has a xed IP address congured in one of the
two tabs “General” and “Alternative conguration”, the
IP address of the PC and the unit IP address must have
the system and sub-system elds in common.
The last part of the IP address is the host number and must
be unique on the sub-system.
For example: Unit address: 172.30.101.11 and PC address:
172.30.101.182.
In this example 172.30 corresponds to the network, and 101
corresponds to the sub-system. Carry out the necessary
modications and try to access the unit again.
In the case of a problem open a command window under
Windows (Start, Execute, type “cmd”<Enter) then type the
command: “ping”, followed by the unit IP address.
