9.2 Troubleshooting Aids
Self diagnostics
The DR4500A recorder runs self-diagnostic tests to monitor the recorder’s general health. The tests are
divided into three main groups and will produce an error message when failed.
An error message can occur
at power-up — run when power is cycled off and on,
during continuous background tests while in normal operation, and
when the Status Tests are requested by the operator.
Table 9-4 lists all the error message prompts that you could see, the reason for the failure, and how to
correct the problem
Visual failure symptoms
Other failures may occur that deal with the power, pen functions, chart rotation, output, or alarms. Refer to
the visual failure symptom in Table 9-5 to determine what is wrong and the troubleshooting procedures to
use to correct the problem.
Check Installation
If a set of symptoms still persists, refer to Section 2 - Installation and ensure proper installation and proper
use of the recorder in the system.
Customer support
If you cannot solve the problem using the troubleshooting procedures listed in this section, get the model
number and serial number from the label on the chart plate, and software version (see "Determining the
software version") then:
call Customer Support Phone Number
1-800-423-9883 USA and Canada
If it is determined that a hardware problem exists and the recorder is still within the two year warranty, a
replacement recorder will be shipped with instructions for returning the defective unit.
