parameter 419 [Brake TP Data] = full open and 1 = full on.

2 - “Power Actual”

Actual power applied to the resistor (Watts).

3 - “Max BodyTemp”

Maximum temperature that the resistor body can handle (°C).

4 - “Max ElemTemp Act”

Maximum resistor body temperature has been exceeded when
parameter 419 [Brake TP Data] = 1.

8 - “ETmpTripStat”

Maximum resistor element temperature has been exceeded when
parameter 419 [Brake TP Data] = 1.

9 - “Int DB Ohms”

Rating of the internal resistor when an internal resistor is installed
(Ohms).
