It's been a while...
Profil 45 now working again.
Tech came again last week.? He was great.? Patient and thorough.? He finally found a contactor that had a burnt out actuator coil.??
What was happening was the system would spin up and then about 4 seconds later (when the power drive was activated) the shaper would spin down again.? No erorr message!
Cheers, David??
