„Pbdr”

Direction error

„Pbdi”

Distance error (Set point and measured value are to similar)

„PbSo”

Source for regulator error

„PnPS”

The device restart during auto-tuning process error

„Pbln”

Input error during auto-tuning

„S.Err”

Sensor error

„-CH-”

Awaiting for temperature measurement

„ErrC”
