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 removing
power.
