succession) and remains set until error acknowledgement.
Set for the following error messages:
- 41046 sequence of conditional errors
Signal is set when e.l.c.b. (earth leakage circuit breaker) has
tripped.
Note: Set when the following error message occurs:
- 11000 Residual Current Circuit Breaker open
- Bit is also set when the input of the Residual-Current Circuit
Breaker
open is not set.
The system reports that one or more phases are missing.
Note: Set for the following error messages:
• 20010 Mains voltage off
• 20013 Mains voltage low
