Directions and the test documents for the Omicron CMC are available on the Internet/
intranet for the above test set-up.
Configuration
Notes In the properties, the parameter Circuit breaker operating time must be increased
by the runtime of the ON command via the process bus in the System data tab. A
measurement is required for determining the runtime.
For synchronisation via the process bus, select the relevant circuit breaker in the
Properties of the SYNC function group in the General tab.
Note
For safety reasons, the maximum permissible frequency difference for the CB syn-
chronisation via the process bus is 100 mHz. Setting higher frequency differences is
not prevented by DIGSI
®
.
It is also possible to allocate the ON command to a binary output. In this case the
maximum value of the frequency difference is permissible.
