I have an ATM generator system that when running off of GTC bleed air, will not hold online past the initial spike of the Aux Pump being turned on. If I apply bleed air from a running engine, the ATM generator will hold the AUX pump just fine. So I guess my question is, is there a minimum air pressure output from the GTC that is required by any tech data? I've adjusted the air pressure regulator on the GTC to MAX out the output, but I'm still only getting 35-40psi from the GTC. Thanks for giving this a read...
Side note: ATM system is basically brand new. List of changed parts:
ATM
ATM generator
ATM fan
GCP
Voltage regulator
Freq sensing relay
Load control valve
