Pump Body Temperature
Read the pump body temperature close to the water circuit.

B0-B3 ñ Status
0 = Stop
1= Waiting for interlock (interlock connections on remote I/O connector
missing)
2 = Ramp (the pump is increasing the speed)
3 = Auto tuning (the speed has been reduced because the gas load is
higher than the Power Limit)
4 = Braking (the pump is reducing the speed using the motor)
5 = Normal operation (the pump is at target speed)
6 = Fail (see error code byte Input Buffer Byte-27)
B4-B7 ñ Reserved
Error Code (bit field)
B7 ñ Too High Load
(the gas load is too high for the pump)
B6 ñ Short Circuit
(a short circuit happened between the two of the three motor phases)
B5 ñ Over-voltage
