INTRODUCTION
HOW TO USE THIS PUBLiCATlON
This publication contains troubleshooting procedures for 2120 expanded transponders (ETs).
Note: Refer to 2120 Expanded Transponder General Information for background information on 2120 ETs.
When troubleshooting an ET, you should have the following documents on hand:
l A copy of the specific ET’s cabinet drawing, supplied with the system. This drawing will show you the
equipment configuration of a specific ET.
l A copy of the specific 2120 Expanded Transponder Functions Sheet (M-1320).
l 2120 Multiplex Troubleshooting Guide.
l 2120 Multiplex Jumper Placement and Switch Settings.
This guide uses flowcharts to help you efficiently isolate ET troubles. Each flowchart is given a figure number;
designations such as “Figure 1A” or “Figure 3C” indicate that there is a group of figures associated with a
particular troubleshooting procedure. Any given flowchart contains all the information necessary to perform any
tests or checks called out on that flowchart. Follow.the flowcharts exactly, and when you reach a figure reference
- PROCEED DIRECTLY TO THE REFERENCED FIGURE.
WHEN TO USE THIS PUBLICATION

being misled by “obvious” trouble symptoms. You will refer to the ET troubleshooting guide under the following
conditions:
l You have reached the Transponder Flowchart in the 2120 Multiplex Troubleshooting Guide and you have
monitor or control point troubles on an ET.
l You have begun troubleshooting a communications problem (i.e., CHANNEL HAS FAILED) in the
Transponder Flowchart and you have isolated the problem to an ET.
l You have an ET power supply problem (POWER/BATTERY FAIL or GROUND FAULT trouble message).
l One of the following troubles refer to an ET:
- XPNDR COM FAILED PRI
- XPNDR COM FAILED SEC
l One or more ET monitor points are locked in alarm.

You should always begin the ET troubleshooting procedures with Figure 1.

This symbol is used to request a certain act, test or
performance. Perform the action before continuing.
This symbol will contain a simple question - usually
based on the action that preceded it. Two points will
be labeled - one point “yes”, the other “no”. Exit at
the point which provides the correct answer to the
question.
This symbol indicates that the steps are continued on
another flowchart. The flowchart figure number will be
written inside the symbol. Flowchart figure numbers
appear at the bottom of each flowchart. A similar
symbol with a reference to the previous flowchart
figure number will appear on the figure indicated.
The reference symbol is used when additional
information is available, and it is always connected to
an action symbol. Refer to the referenced material
priorto performing the action.
This symbol indicates that the steps are continued on
another part of the same page. The numberwithin the
circle will match the number in a circle at the point
where the flow continues.
This symbol indicates that a very serious malfunction
exists and additional assistance is required. The
information within the symbol will recommend a
source of aid.
