PAC#_REF
(# = 1, 2, 3 or 4)
+5V voltage reference fault is less than
4.6V
Mute all PAs for the designated PA
Controller and energize all its relays.
Transmitter power output will decrease but
will continue to operate as long as only one
PAC is affected.
PAC#_VOLTS PS# fault: Less than 30VDC, or more than
60VDC, turns off its PAs, other 3 controller's
PAs still operate
Mute all its PAs & energize all its relays
PAC#_-15V Without -15V, PAC# has lost its ability to
MUTE the PAs under its control.
Request another controller to mute the PAs
controlled by designated PAC.

The designated PA is not properly seated in
the connector. Make sure the module is
properly inserted and the thumbscrews on
the PA module are engaged (where # is a
number from 1-8).
Mute XMTR 120ms, switch out the PA and
release the mute on the rest of the PAs. Re-
inserting the PA into the connector should
clear the fault and re-initialize the PA and
the system.

Designated PA cannot be muted. Any time
PAs are muted the system checks to see if
any PA is drawing current. If so, then the
controller does not have the ability to mute
that PA and the mute fault is activated.
Mute XMTR 120ms, switch out the PA and
release the mute on the rest of the PAs
