Testing Card Installation
Booting and Power-Up Self-Test
Immediately after power-up of the Smart Trac AC1 with the CPU card installed,
the validity of the operating system is checked. The Smart Trac AC1 BIOS
(Basic Input Output System) performs a self-test to determine the integrity of
RAM, flash memory, system timers and interrupts, among other checks. Any
detected faults appear on the Smart Trac AC1 digital operator.
Next, the system loads any installed drivers. It checks the validity of the user
program before starting its execution.
Once drivers are installed and the user program is validated, the system
performs according to the user program, responding with diagnostics and error
handling as necessary.
NOTE: If communication with the Smart Trac CPU and other cards in the
Smart Trac AC1 are not established within seven (7) seconds of power-up or
after about two (2) seconds without data being transferred, it will shut down.
The LEDs on the digital operator will flash, indicating this lack of
communication.
