1)Only with broken wire monitor activated, error bit = 1 only for faulty channel; for sensor broken wire, overflow bit = 1 for all channels

2)On account of the Pt 100 series circuit, this bit combination always appears for all channels if the supply line is open-circuit.

A = Active bit

E = Error bit

OV = Overflow bit

S = Sign
