Recognition of network overvoltage
Having display signals of input supply, normal status (output energization), phase sequence, asymmetry in voltage of three phases, uncdervoliage and overvoltage
Principles of Operation
The device starts working after connection of three phases to terminals R. § T and 380V 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 de- vice intemal relay opens (intemal 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 undervoltage. overvoltage. a phase loss or phases reversal in network. the related fault signal gets ON. OUT signal gets OFF and intemal relay closes simulfaneously (internal contact of terminal 15 to 16 is made).
Installation and Start-Up
The network three phases have to be connected to terminab R. 5. Tand 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 terminals T and R. Terminaé 15 and 18 have to be in series in circuit like a stop button. lf P.S (phase sequence) signal is on after device installation. the location of two phases on Thréee-Phoase-Monitor should be reversed (e.g. R. 5) for related signal to be off. Once ony 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 po- tentiometer handle. This value could be set in range of 5 to 15%.
