IPA_LOAD Z-Plane currents are checked during
startup to determine if IPA load is
balanced. Most likely caused by bad RF
cable.

PSC#_COMM Communication lost between Master and
one of the PS controllers
Indication of fault (no other action taken)
PAC#_COMM Communication lost between Master and
one of the PA controllers

RF Source 1
RF Source 2
The RF source has signaled the
transmitter that it has a problem. For more
information on RF source faults refer to
the corresponding manual.
An RF source FAULT is detected, and is
recorded in the transmitter fault log.
RFSource1_LOW
RFSource2_LOW
The exciter, or BoostPro, has signaled the
transmitter that its RF output has dropped
below normal limits.
Controller will then delay 40 seconds before
switching to 2
nd
exciter or boost amp, if it is
available.
