was working on a trane chiller model=ECGAL600 system 2 was showing a fault ACKT2 limiting then it cleared it"s self.running pressures look ok. 4bar and 10 half bar i think that fault code means water temp has past set point.am i close to meaning or miles away??
It means load of compressor is limited due to high water temperature to protect itself!
So it could have shown this reading as a warning.the chiller was swicthed on after being off for a few weeks.thanks for the information
When the temperature is too high the machine will protect itself, because the pressure will get too high!
