The relay of control of phases with controls loss (existence) of a phase, sticking of phases, an order sequence of phases, asymmetry of phases (40%), the neutral, with fastening on dynes a lath of FKV-14, TENSE is necessary
Algorithm of operation of the relay of control of phases: in the presence of all three phase or linear tension connected in the correct sequence - the relay is in working order and contacts 15-18 are closed, the light-emitting diode of OUT is highlighted. If tension of any of phases changes more than for 40% (or total multidirectional change exceeds this limit) contacts 15-18 are disconnected, contacts 15-16 become isolated and the svetoindikator of OUT is switched off. Too occurs if the order of alternation of phases is broken, the indicator is in addition switched off
At return of parameters to the set limits, the relay passes into a working condition again.
