17. COMMISSIONING
Testing to be carried out when installation concluded, wiring and configuration completed and
checked.

1 Testing C-Ring
Ensure that all the other controllers connected in C-Ring are :
– correctly powered by 230 V AC (or 240 V AC for UK market)
– Slave controllers or configured as SECONDARIES in
– selected on testing page
The “PRIMARY” controller sends a signal every 5 seconds via C-Ring. On all the displays appears
“??”. If the connection is positive, “OK” replaces “??” on all the displays.
If on one or more displays “OK” does not appear, this means that there is a break between the last
controller with “OK” and the first with “??”.
Examples of testing a C-Ring setup with four controllers :
– Cont.1 "OK" – Cont. 2 "OK" – Cont.3 "OK" – Cont.4 "OK" : Wiring positive
– Cont.1 "??" – Cont. 2 "OK" – Cont.3 "OK" – Cont.4 "OK" : Break between 4 and 1
– Cont.1 "??" – Cont. 2 "OK" – Cont.3 "??" – Cont.4 "??" : Break between 2 and 3
– Cont.1 "??" – Cont. 2 "??" – Cont.3 "??" – Cont.4 "??" : Break between 1 and 2
