The LED sets to o when the rotaonal speed is very low or stopped.
If the next service is available, the LED ashes in a sequence to show
which service operaon is necessary. Refer to Fault nding on page

If an e
xternal electrical load is connected to the normal output line, the Normal LED can
come on.
