Description
Dim.
ETP
Temperature
[869]
Temperature of the ETP sensor. After exceeding the temperature defined in the
parameter ETP Warning [865] (page 105), the converter generates a warning. After
exceeding the temperature defined in the parameter ETP Fault [866] (page 105), the
converter generates the fault " E38-ETP temperature (page 33)".
