Diagnostic LED
The Diagnostic LED Figure 6) flashes in three different states when the
processor is working properly:
 When the pump is idle and in 'stand-alone' mode, the LED flashes
slowly and consistently.
 When the pump is idle and communicating with a controller the LED
flashes slowly but erratically.
 When the nozzle is lifted from its holster, the LED flashes quickly.
