12 Volt Power Supply Test (#701)
This test is nondestructive. The purpose of the test is to diagnose the 12 volt
power supply unit in the TN798 Processor circuit pack. No erase and
write-to-memory operations are started or verified during the test. The contents of
flash memory and of the memory card should not be changed.
The test turns on the power supply and verifies that 12 volt power appears by
reading the control register in the Processor circuit pack. After the power supply
is turned on, the maintenance software waits for three seconds before verifying
the appearance of 12 volt power. After the 12 volt power supply can be turned on
and verified, the test turns the power supply off and then verifies that the power is
off. The control register is read again for the verification.
If, while this test is running, an application attempts to erase or write a flash
memory or a memory card, this test remains active, and the application is barred.
