144 UDC 6300 Process Controller Product Manual 1/03
5.2 How to Power Up The Controller
Apply power
When power is applied, the controller will run three diagnostic tests. All
the displays will light and then the controller will go into automatic mode.
Diagnostic tests
Table 5-1 lists the three diagnostic tests.
Table 5-1 Power Up Diagnostic Tests
Prompt on Lower Display Condition
RAM TEST
Checks RAM memory
CONFTEST
Checks the controller's software
configuration for inconsistencies.
CAL TEST
Checks calibration of the controller's
configured analog inputs and outputs.
Test failures
All the displays and indicators will light and then display "TEST DONE".
If all these tests pass, the controller will function in a normal manner
without any diagnostic messages.
If one or more of these tests fail while checking memory, the controller
will go to the Fail-safe Manual Mode, and “FAILSAFE” will flash in the
lower display.
Troubleshooting
Refer to “STATUS TESTS” in Section 8- Troubleshooting to identify and
correct the problem.
