DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

• Apply appropriate personal protective equipment(PPE) and follow safety work practices

• Only qualified electrical workers should install this equipment. Such work should be performed only after reading this entire set of instructions.

• If the equipment is not used in the manner specified by the manufacturer, the protection provided by the equipment may be impaired.

• NEVER work alone.

• Turn OFF all power supplying the monitoring device and the equipment in which it is installed before working on it.

• The successful operation of this equipment depends upon proper handling, installation and operation. Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property.

• NEVER bypass external fusing.

• NEVER apply the voltages at Program Lock and Auto Reset terminals.

• Before performing Dielectric or Megger testing on any equipment in which the monitoring device is installed, disconnect all the input and output wires to the monitoring device. High voltage testing may damage electronic components contained in the monitoring device.

• The monitoring device should be installed in a suitable electrical enclosure.

Failure to follow these instructions will result in death or serious injury.

• 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 device.

Keys and Operation

MENU/ENTER/HOLD/SCROLL Key

RUN Mode : Used to select scroll/hold the

parameters.

PROGRAM MODE : Used to enter into program

mode.

: used to select next parameters.

INC Key

PROGRAM Mode : Used to increase the values.

DEC Key

PROGRAM Mode : Used to decrease the values.

MANUAL/ESC Key

RUN Mode : When fault recovery happens this key shall be used to Load ON/OFF manually.

PROGRAM Mode : It is used to view the previous parameters.

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

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.
