Ensure that the controllers connected in C-Ring:
– are correctly powered from the mains at ( 230 V~).
– one controller only is configured as

– all the controllers are selected on the testing page
DTC 628 sends via C-Ring a signal every 5 seconds. On all appears. If the connection if satisfactory
the word “YES” replaces “??” on all the displays. If on one or more displays “YES” does not appear
this means that there is a break between the last controller with “YES” and the first with “??”:
Examples of testing a C-Ring with four controllers:
– Cont.1 "YES" – Cont..2 "YES" – Cont..3 "YES" – Cont. 4 "YES" : Connection OK
– Cont.1 "??"
– Cont. 2 "YES" – Cont. 3 "YES" – Cont. 4 "YES" : Break between 4 and 1
– Cont.1 "??"
– Cont..2 "YES" – Cont. 3 "??" – Cont. 4 "??" : Break between 2 and 3
