Principles of Operation:

The device starts working after connection of three phases to terminals R. $. T and

S80V power supply to terminals Al and A2.

PWR input supply signal gets ON in this situation and the device starts timing. At the

end of adjusted time by DELAY potentiometer handle. OUT signal gets ON and the

device intemal relay opens (internal contact of terminal 15 to 18 is made).

Attention: Timing does not start where any fault signal is on.

In the case of any fault like undervoliage. overvoltage. a phase loss or phases reversal

in network. the related fault signal gets ON. OUT signal gets OFF and intemal relay

closes simultaneously (internal contact of terminal 15 to 146 & made).

Installation and Start-Up:

The network three phases have to be connected to terminals R. 5. T and 380 V power supply to terminals Al and A2.

 Attention: In the case of no separate 380 V voltage. terminals Al and A? can be connected to tenminals T and R_

Terminab 15 and 18 have to be in series in circuit like a stop bution.

if PS (phase sequence) signal is on after device installation. the location of two phases on Three-Phose-Monitor should be reversed (e.g. R. 3) for related signal to be off. Once any of the mentioned faults happen. internal relay closes and relay opens at the end of time (adjusted by DELAY potentiometer handle) and OUT signal gets ON right after fault correction. This time ranges from 0.5 to 30 seconds.

Recognition of asymmetry in voltage of three phases gets adjusted by ASY.V potenti- ometer handle. This value could be set in range of 5 to 15%.
