Technical Specifications:
1] Supply voltage: 3 Phase 415 VAC, 50 Hz (R, Y, B &N) (No
auxiliary supply)
2] Output Contacts: Two SPDT (C-N/O-N/C) Relay, Rating
5A at 250V AC
3] Indications: FAULT (UB/SPP/REVP, UV, OV, UF, OF):
RED LED, RELAY ON: GREEN LED
4] Keys:
1) SET: SET key, Press to enter into SET Mode
2) INC: Upward Arrow key, Press to increment the setpoint.
3) DEC: Downward Arrow key, To Decrement the setpoint.
5] Operating Temperature range: -5 C to 60 C.
6] Relative Humidity: 10 to 95% RH
7] Mounting: Flush
8] Dimensions: 96 X 96 mm.
Working:
1] If the Input supply is within the range of the fault limits then
On Timer starts decrementing on display & after Set On
Time over Relay will be 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 & fault LED starts blinking.
3] If any Phase to Phase Voltage increases above OV set
point, Relay will trip after trip delay (<100 ms) over. If that
particular phase to phase voltage reduces below (OV set
point - 10 V), Relay will be ON after the set reset delay over.
4] If any Phase to Phase Voltage increases/reduces
above/below the UB set point compared to other two Phase
to Phase voltages, Relay will trip after set trip delay over. If
that particular phase to phase voltage reduces/increases
below/above (UB set point -/+ 10 V), Relay will be ON after
the set reset delay over. If the frequency reduces below UF
or increases above OF then the relay will trip. Hysteresis is
1HZ.

5] If any of the Phase fails, Relay will trip after trip delay
(<100 ms) over. If all phases are present, Relay will be ON
after the set reset delay over.
6] If Phase sequence is changed to R-B-Y/Y-R-B/B-R-Y,
Relay will trip after trip delay (<100 ms) over. If phase
sequence is corrected to R-Y-B, Relay will be ON after the
set reset delay over. UB/SPP/REVP, UV, OV, UF, OF.
