The measured current is monitored after
expiration of the "Tolerance time" for "Tol-
erance factor × Measured current". Ex-
ceeding this results in overflow current.
The maximum value of the secondary
current (12 A) has been exceeded.

If the "Undervoltage" and "Low limit" diagnostics are active at the same time, the "Low limit" diagnostics has higher
priority and deletes the "Undervoltage" diagnostics.
