NORMAL OPERATION
1. LEDs 1, 2 and 3 Sequence back and forth to indicate the processor is on-
line and operational.
2. LED 4 is used as a discrete/analog signal to the upper console.
3. LED 5 indicates system status/mode. Currently 3 modes are defined safe
mode, stand-by mode and run mode. They are defined as follows:
a) Safe Mode - When the controllers safety relay is not energized and no
error exists, LED 5 remains off.
b) Stand-by Mode - When the safety relay is engaged but the system is not
outputting an active PWM to the motor and no error exists, LED 5 blinks off
and on at a fast rate.
c) Run Mode - When the system outputs an active PWM Control signal to
the motor and no error exists, LED 5 remains ON.
