INSTALLING MODULES

After installing the base ATLAS 800PLUS unit and connecting the required cables, you can install modules. If you need instructions for installing a module, refer to the User Manual for the module you want to install.

POWER UP TESTING AND INITIALIZATION

After installing the base unit and any modules, the ATLAS 800PLUS is ready to be powered up.

When shipped from the factory, the ATLAS 800PLUS is set to factory default con- ditions. When you power up the unit, it automatically executes a memory self test. You can run a full self test from the front panel and set a pass code (through the UTIL menu) and unit ID (through the CONFIG menu) from the front panel. See “Unit ID” on page 4-6 and “Set Passcode (Front Panel)” on page 4-8 for details.

Self-Test

Upon a power-up, the test LEDs light up and the LCD displays the message Memory Test Now Testing. When the self test is complete with no failures detected, the OK LED lights up and the LCD momentarily displays All Tests Passed. If a failure is detected, a list of failures displays in the LCD window. The full self test procedure consists of the following steps:

1.Board-level tests. The Controller contains an on- board processor which executes a series of tests checking the circuitry on the board.

2.RAM tests; EPROM checksum.

3.TDM map tests.

4.On-board data path. Sending a known test pattern through an on-board loop.
