software via the RS232 interface. The fault file will provide fault
information and possible causes. The HFG2.0 must be in the Power Up /
Set Up state to download the fault file. See Section 3.8 for details about
the Power Up / Set Up state. Contact Precision Engine Controls
Corporation to request ActWiz software.
