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).
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
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 follo ing table:

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 follo s
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 %

HINTS ON CORRECT USAGE
 Use proper gauge wires for connections to get
proper readings.
 Ensure all terminals are tightly screwed.
 Voltage should not exceed specified limits. It will
damage the unit beyond repairs.
CAUTION
 Ensure MCB protection is available between input
bus bars and unit
 Since it is a high voltage device, only licensed
people should handle it. Proper care should be taken
like switching off the main incoming line before
working on the meter.
 EAPL is not responsible for any consequential
damages arising out of use of our products, though
the technology is cautiously chosen and
implemented like any other well designed good
electric meter
 Blinking of unit indicates over voltage.
S itch off the unit for 1minute to reset the
resetable fuse & s itch on.
Applicable for Aux supply 85 to
270V AC/DC only.
DISPOSITION
Once the product life is over, you may send back the unit
to EAPL for disposition.
TROUBLE ANALYSIS
1) Phase fail display
 Check whether all the 3 phase voltages are
given properly.
2) Faults like (UVOL,OVOL)
displayed
 Go to program mode ( short 5 6) settings and
set the value as per the requirement.
3) Relay is not tripped
 Go to the program mode and check the
“rly”option
 Check whether Auto reset (6 7 terminals) are
short.
 For manual mode press manual /esc button.
(After recovery from the fault or program mode)
