Troubleshooting
The significance of the red LED
When operational faults occur the LED flashes a number of times. The number of pulses
depends on the type of fault.
Each flash lasts for one quarter of a second. After the series of impulses a pause follows. The
sequence for the fault is repeated every four seconds.
