Keys and Operation
RUN Mode
1. On power application, relay will be in NC condition for
approximately 10sec.
2. During healthy condition, all the voltage parameters shall be
displayed with instantaneous values. Relay and relay LED will
be in ON or OFF condition depending on Rly ’y’ or Rly ‘n’ setting.
3. During fault condition, type of fault shall be displayed with
Relay OFF or ON Status depending on Rly ’y’ or Rly ‘n’ setting.
Auto mode
4. Once the fault is recovered, unit automatically comes back
to parameter display mode as mentioned in point – 2.
Manual mode
5. Once the fault is recovered, manual key to be pressed to
bring back display mode as mentioned in point – 2.
6. If faults are rectified before set trip delay timings of relay,
display will continue to show fault status. Relay status remain
unaltered. Press Manual key to show the parameter display.
Press MENU/ENTER key for 3Seconds to HOLD/SCROLL display.
When fault occurs unit display’s the following:

Phase Unbalance Condition
To set unbalance condition for 20%.
Set 20 in unit (PUbL=20 as shown in the table).
If RY=350V, YB=450V, BY=319V in the load.
Fault is created in the unit, upper displays shows “Phs” and
lower shows “UbAL”.
Calculations are as follows
Set nVOL=415V, PUbL=20% in the unit.
Vry=350V, Vyb=450V, Vbr=319V, Vavg= 373V
Vry -Vavg=23V, Vyb -Vavg=77V, Vb-Vavg=54V
Phase unbalance= (Maximum deviation / Vavg) * 100
= (77/373)*100= 20 %
PROGRAM Mode
To enter program mode press INC & DEC key simultaneously for 4sec.
