When rLY 'Y ' is selected
relay will be ON i.e. ( C to
NO) . When fault occurs
relay goes OFF i.e. (C to
NC).
CntL "rLY Y/n"
When rLY 'n' is selected
relay will be OFF i.e.(C to
NC). When fault occurs
relay goes ON i.e. (C to NO
DOC NO: OD RE YN 21005 0 Rev No: 05
RUN MODE
A power ON delay is seen. During this state the
relay will be in NC condition and Relay status
LED will be Off.
Top window will display voltages and Bottom
window will display respective parameters.
In manual mode, the relay will energize and
change over takes place to NO and relay status
LED comes ON only when the user presses the
ESC/Manual button. Till such time the relay
status LED will be OFF.
In Auto mode ( i.e short 6 & 7 terminals), the
relay will energize, change over takes place to
NO and Relay status LED will come ON
immediately after the power ON time is over.
When fault occurs refer the following table:

PHASE REVERSE Phs rEU
R PHASE FAIL FAIL P-r
Y PHASE FAIL FAIL P-Y
B B PHASE FAIL FAIL P-b
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 = 20 %
.
