Printed Circuit Board (PCB) Status LEDs
There are two small, surface-mount green LEDs on the PCB located on the back
left corner of the PCB (when looking at the analyzer). You must look up into
the electronics enclosure to view these LEDs, they are not visible when looking
directly at the analyzer.
REAR LED
– Heart Beat LED. Blinks once a second indicating the analyzer
software is operating. If off or not blinking this indicates the power is off or the
electronics are not functional.
FORWARD LED
– Modbus Communications LED. Toggles upon receipt of a
valid Modbus message. This LED will blink rapidly in short bursts when com-
municating properly to the Display User Interface.
