Meas. val. sensing
F029
A fault has occurred in the measured value sensing
circuit.
?(r949 = 1) Offset cannot be adjusted in phase L1.
?(r949 = 2) Offset cannot be adjusted in phase L2.
?(r949 = 3) Offset cannot be adjusted in phases L1 and
L3.

Defect in the measured value sensing circuit
Defect in the power section (valve is not blocking)
