Introduction
IntroductionIntroduction
Introduction
The digital energy meter E3000 is a micro-controller based unit which not only
measures a host of electrical parameters to display them on a customized segment
LCD with white backlit, but also acts as a comprehensive load control device due to
its three numbers of internal latching relay contacts. These latching relays will cut
load when either load exceeds KW limit or force tripped from RS485. In addition to
this flexibility in terms of load control, the meter also has two serial ports. Both port
follows RS485 medium. One port is for EMS/SCADA and second for Remote Display
Unit. RS485 supports MODBUS RTU protocol for connections to EMS/SCADA.
The unit is meant for use in three phase four wire systems with Active Power (KW)
control. The meter address, tripping parameters, resetting the energy, date & time in
RTC are site programmable.
E3000 has dual source input. So when 230Volt AC input applied at dual source
input, then meter will register DG Energy.

Installation and Commissioning
Installation and CommissioningInstallation and Commissioning
Installation and Commissioning
The unit supports only for 3P4W electrical installation and user is advised to read
carefully the instructions before installing and commissioning.
Follow the steps below to install and commission the unit
1. Push the unit into the panel and mount on the wall.
2. Connect the three phases with the phase sequence being R-Y-B to the
terminal marked, 1, 4 and 7. Connect the neutral wire to the terminal marked,
10. Make sure that the three phases coming to the meter come through the
control fused appropriate Amp rating. This will protect the electronic inside
from damage due to severe overvoltage or phase faults in the systems.

3. The three phases R, Y and B coming from load will connect to the terminals
marked 3, 6, and 9, and then connect the neutral wire to the terminal marked
10.
4. In case of DG, the two wires coming from the DG will connect to the terminals
marked 25 and 26(DP and DN) with a supply voltage of 150VAC to 270 VAC.
Now, switch on the three phase supply, then the unit will display power
receiving information such as TESPL, and then the unit comes to RUN mode
displaying KWH and increasing value in DG.
5. Firstly, the unit should be programmed for various programmable parameters
in the Programming Mode. For this, see ‘Operational Details’ in the next
section.
6. Now, the unit is ready for the Operation.

Operational Details
The unit, E3000 is a versatile meter with the feature needed to implement with a
robust electrical system and can also be configured to suit for most electrical
revenue purpose. The unit is achieved by making as many parameters field
programmable, as much as possible. There are basically two modes of operation:
1. Programming Mode
2. Run Mode.
After supplying power (100 VAC to 440 VAC) to the three phases, the unit comes to
Run Mode by default after displaying power receiving information, TESPL such as
shown below.
Programming Mode
Programming ModeProgramming Mode
Programming Mode
The unit has various user interface programmable parameters and the Programming
Mode can also be easily interfaced by using the keys PROG, UP and DOWN. The
unit is designed with a fixed password protection,”1947”. The user will therefore
enter a password before entering into Programming Mode. Now, in Run Mode,
press PROG key for about 5 seconds and then, the password display will prompt
such shown below.
To enter the password, press PROG key again that will start blinking first digit as
zero and is also showing that the password can be entered. Now, press UP key to
set to 1; press PROG key to shift to second digit and enter 9 by pressing UP or
DOWN keys. Likewise, enter 4 and 7 also, and then press PROG key to enter into
Programming mode. In case, the password entered is wrong, the unit will show Error
(ERR) and return into Run mode. Enter again the exact password as steps before.
On other hand, the password prompt will return into Run Mode, unless the password
is entered for about 30 seconds. Or, if the unit is in Programming Mode and keys
are not operated for about 30 seconds, unit will return to Run Mode.

display first programmable parameter, UNIT ADDRESS such as shown
below.
2. Press PROG key. Immediately, the parameter will start blinking which shows
that the parameters can now be changed. Set the parameter by pressing UP
or DOWN keys and press PROG key again to confirm the setting. The

Setting EB TRIP LIMIT, TRIP DELAY and TRIP O TIME on KW
Setting EB TRIP LIMIT, TRIP DELAY and TRIP O TIME on KWSetting EB TRIP LIMIT, TRIP DELAY and TRIP O TIME on KW
Setting EB TRIP LIMIT, TRIP DELAY and TRIP O TIME on KW
The unit has relay for tripping on KW limit with a settable value from 5KW to 60KW.
The TRIP DELAY is the time duration for which the relay will wait for setting time
duration before switching off. The TRIP DELAY is settable from 1 to 15 minutes.
TRIP OFF TIME is the time duration for which the load will be switched off with
selected time duration before switching on. This TRIP OFF TIME is settable from 2
to 60 minutes.
For example, the TRIP Parameters are set such that:
TRIP LIMIT – 25 KW
TRIP DELAY – 5 MINUTES
TRIP OFF TIME – 15 MINUTES.
The unit will check continuously for system KW value. If KW will exceed its limit say
30 KW then the unit will keep a watch on this value for next 5 minutes. If the value of
KW remains above 25 for this 5 Minutes then the unit will cut off the load by tripping
the relays off. This load will remain cut off from the mains till next 15 Minutes as set
in the TRIP OFF TIME parameter. After this duration the unit will again switch ON
the relays and load will be connected to mains. In this state the TRIP LED will

[11]
remain ON. If the value of KW will remain above its tripping limit only for 3 minutes
then in this particular case the trip action will not be performed and hence the load
will not be cut from the mains.
To set the trip parameters, proceed the following instructions.
1. After entering the password, the unit will enter into Programming Mode and
display first programmable parameter, UNIT ADDRESS. Press UP key to
enter into TRIP LIMIT such as shown below.
2. The digit 1 at the top of the left corner shows the trip parameter is for EB only.
Press PROG key. Immediately, the parameter will start blinking which shows
that the parameters can now be changed. Set the parameter by pressing UP
or DOWN keys and press PROG key again to confirm the setting. The
parameter blinked will also stop blinking. To set for next parameter, TRIP OFF
TIME, press UP key to display with the following display.
3. Now, set the TRIP TIME as steps before. And press UP key again to set the
next parameter, TRIP OFF TIME with the following display.
4. Now, set the TRIP OFF TIME as steps before. To set for next parameter,
press UP key and set as steps before. Otherwise, press PROG key to return
