Output ContactsTwo changeover (C-NO) Relay, Rating 5A at 250V AC
IndicationsFAULT (UB/SPP/REVP, UV, OV, UF, OF): RED LED, RELAY ON: GREEN LED Relative Humidity: 10 to 95% RH Cutout : 92(W) x 92(H) mm 3)UNDER VOLTAGE: RED LED Overall(Bezel) Dimensions : 96(W) x 96(H) x 80(D) mm
KeysSET: SET key, Press to enter into SET Mode INC: Upward Arrow key, Press to increment the set point. DEC: Downward Arrow key, To Decrement the setpoint
Working1) If the input supply is within the range of the fault limit limits then On Timer starts decrementing on display & after set on Time over Relay will de ON with RLY indication glowing; 2)If OV, UV, OF, UF, SPP/ reverse phasing / Unbalance occurs in the supply then relay will be OFF after the trip delay of that particular fault & LED starts blinking; 3) If any phase to Voltage increases above OV set point delay will trip after trip delay (100)ms ) over .If that particular phase to phase voltage r
