INSTALLING MODULES
After installing the base ATLAS _ 800
PLUS
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 _ 800
PLUS
is ready to be
powered up.
When shipped from the factory, the ATLAS _ 800
PLUS
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.
