2.9 Self-monitoring and diagnostics
All other warnings can also be deleted via the ETU600 display in the "4.6.1 INFO
warnings" menu.
In principle, occurring errors can be assigned to the following 3 groups.
Serious error with circuit breaker tripping
A serious error with tripping is a type of fault that influences the protective function of
the circuit breaker so much that regular operation can no longer be ensured. In this case,
the circuit breaker is tripped immediately. Further operation of the circuit breaker is then
no longer possible. A service assignment by a Siemens-certified technician is necessary.
