A14R138

MD-2 

♠

IPA HIGH THR

Adjusted to set the IPA forward power monitor
threshold to 600 watts.  Causes RF output to be
shutback when IPA forward power exceeds this
threshold.

A14R147

MD-2 

♠

IPA OUTPUT

Adjusted to set the threshold at which point the
switching power supplies A thru F and hence
transmitter output will be inhibited due to the
detection of low IPA output.

A14R151

MD-2 

♠

LOW RF

Adjusted to set the forward power to RF power
amplifier  module supply VDC threshold to the level
that will inhibit the IPA output when the RF power
module supply is unchanged but forward power level
is reduced because thirteen or more RF power
amplifiers have failed or three or more RF power
amplifier module's circuit breakers have been tripped.

♠

Denotes item is located on the control/monitor PWB.  Refer to the control/monitor PWB's assembly detail

drawing in its service instruction manual to locate these items.
