• LED – see illustration (above).
• Status information (see command descriptions in
6000 Series Software Reference Guide):
Axis status (general problem conditions)...TAS command
Limit switches.............................................TLIM command
Programmable and trigger inputs...............TIN command
Programmable outputs...............................TOUT command
• Programmable input functions (INFNC command) will not be operable until
you enable input functions with the INFEN1 command.
• To help prevent electrical noise, shield all connections at one end only.
• Error messages while programming or executing programs – see the
6000
Series Programmer's Guide.
• Download errors – see page 21.
• Address, transfer mode, and interrupt DIP switch settings – see page 4.
• Technical support – see phone numbers on inside of front cover.

Automation
downloading the operating system, the status LED will
turn green indicating the system is ready for operation.
If the LED does not turn green after downloading the
operating system, an error has occurred. The
download program (AT6400) issues an error message
if it cannot find the card or if the download operation is
not successful (refer also to the Downloading Error
Table provided Chapter 2).
Board Monitor Alarm (BMA): Detects un-recoverable
faults in hardware and software. When the BMA
detects a fault, the LED turns off. The BMA can be
reset by cycling power to the PC-AT, or by re-
downloading the operating system.
After applying power, the LED will be off. After
