If all L1, L2, L3 phase voltages are balanced and
there is no missing phase normal LED turns on and
the relay energizes its contact.
If phase-neutral voltage unbalance value exceeds
+ 20 %, normal LED turns off and relay de-energizes
its contact.
When the unbalance returns to normal boundary,
normal LED turns on and the relay energizes its
contact again.
