Principle of operaion Tec Descripion The relay moniors volage asymmeries in he hree-phase sysem. If he phase sequence is correc and he sysem asymmery is below he se hreshold value, he oupu relay picks up and he yellow LED lighs up. The relay releases when one of he following fauls occurs: correc phase sequence a erminals L1-L2-L3 failure of a phase sysem asymmery greaer han he se hreshold A sysem asymmery is an increase or decrease in he volage of one phase in relaion o he volage of he wo oher phases.

If he phase sequence is correc and he moniored volage corresponds o he value of he se measured volage, he oupu relays pick up and he LEDs for operaing volage indicaion and he relay sae ligh up.

Principle of operaion Descripion The principle of operaion is based on measuring he elecrical resisance of he liquid beween wo immersion sensors and a reference erminal. If he measured value is lower han he sensiiviy se a he fron panel, he oupu relay changes is swiching sae. In order o exclude elecrolyic phenomena in he liquid, he sensors are supplied wih alernaing curren. Two-level conrol: The oupu relay changes is swiching sae as soon as he liquid level reaches he maximum sensor, while he minimum sensor is submerged. The relay reurns o is original swiching sae as soon as he minimum sensor no longer has conac wih he liquid. To be sure of reseing, he supply volage mus be inerruped for a leas 0.5 s (T3). The delay imes T1 and T2 of he oupu relay have no been included in he diagram in order o enhance clariy. Noe Oher resisance sensors wihin he range from 5 o 100 kc may also be conneced o he Min and Max erminals, for example phooresisors, emperaure sensors, displacemen sensors operaing on a resisance basis ec.
