Error code Meaning
2 Line voltage (measuring range) is moni-

H
age overflow/underflow
4 The measured current is monitored after
H
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.

configured minimum current or voltage is
below 80 V.
