6 | BEAT | Yellow | Heartbeat, normally 1 Hz 50% duty cycle |
7 | STAT | Green | Remains lit when controller is on |
If the BEAT LED stays on constantly, does not light, or blinks very fast, have your ABCS Distributor contact the FSC or your appropriate technical support group.
Important: The 1 Hz, 90/10 percent on/off BEAT
flash at startup also occurs during other critical operations, such as a firmware
upgrade to the controller or any attached modules. To be safe, do not remove power from
the controller while its BEAT LED flashes with a 90/10 percent on/off duty cycle.
Wait for the normal 50/50 percent flash to return before you remove power.
