CONTREX M-Traverse - Manual (Page 138)

4 - 11
In addition to the diagnostic tests 1-10 that you can perform, the M–Traverse
automatically performs two power up diagnostic routines during every power up.
RAM TEST - Random Access Memory
The M–Traverse performs a pattern read/write test on RAM.
If RAM fails, error code “-----5” appears in the upper LED display.
The test will stop if a failure is detected.
Press “Clear ” to continue the test.
IF the RAM is good, the M–Traverse will begin the PROM test.
PROM TEST - Programmable Read Only Memory
The M–Traverse performs a checksum comparison on the PROM.
If the test fails, error code “-----3” appears in the upper LED display.
The test stops if a failure is detected.
Press “Clear”.
If PROM is good, exit is automatic. The M–Traverse will begin the initialization
routines and normal operation.
