5.2 TRITON TRACTION UNIT TESTING
5 TROUBLESHOOTING
A. General- Electronic
1. Information within this section in respect to
electronic components is intended to aid
in troubleshooting the PCB's of the Triton units
to “Board Level” only.
These tests are the standard testing
procedures and methods used at the factory
before shipment of the unit.
2. Due to the complex nature of the technology
utilized by Chattanooga Group, the
recommended PCB troubleshooting
techniques are to determine “Bad Board” and
board replacement only. No PCB
component level troubleshooting is
recommended nor will information or parts
be supplied by Chattanooga Group. Any PC
board component level troubleshooting
performed will be at the sole risk and liability
of the Service Technician performing such
troubleshooting techniques.
3. Once a particular PCB has been
determined as bad, replace the PCB. Use
only Chattanooga Group replacement parts
and hardware.
B. General- Replacement Components
Critical component replacement parts for the
traction unit are available as subassemblies only.
This is due to the accuracy required and the
critical nature of the subassembly within the
unit for power function and operation. Individual
components of these subassemblies will not be
made available by Chattanooga Group.
C. General- Tests and Repair Procedures
1. Certain tests and repair procedures require
the use of special tools and/or fixtures.
These will be listed at the particular test
where they are required. Testing with any
other special tool or fixture other than those
stated could give erroneous readings or test
results. Always perform the tests exactly as
stated to ensure accurate results.
2. Test equipment settings will be listed for
each test performed prior to the respective
test to ensure the test is performed to
Chattanooga Group standards and ensure
power readings.
3. The troubleshooting and repair of the
units are to be performed only by authorized
technicians trained and certified by
Chattanooga Group.
D. Tools, Fixtures, and Equipment Required
1. Dielectric Withstand (Hi-Pot) and ground
resistance tester.

The tool, lubrication, and locking compound
requirements listed are critical to component
removal and replacement of the unit.
The hardware, bolts, nuts, and screws used to
assemble the Triton are SAE and Metric. Therefore,
it will be necessary to obtain both SAE and Metric
tools for removal and replacement of components.
The lubricant and locking compound listed are
crucial in the assembly of certain components to
ensure patient safety and efficient operation of the
unit.
