Product & features at glance :
This Manual is applicable for the Models: LG+AYXX A indicates display
parameters & Y indicates nos of rows and may be replaced by any one digit
number from 1 to 9. XX indicates software variants without any change in
hardware construction and may be replaced by any two digit number from 00 to
99.Throughout this manual, the following methods are used to highlight
important information:
NOTE : Describes important considerations related to a device setup, feature or
application.
CAUTION : Alerts you to a condition which could potentially cause damage to
the device or other external equipment.
WARNING or DANGER: Warns you to avoid such conditions that could
potentially cause serious personal injury and/or damage to equipment.
Preventive Measures :
 Fuse: To avoid the possibility of short circuit, use a fuse that has a rating
(current and type) that is specified. When replacing a fuse, turn OFF the
power and unplug the power cord. Never short the fuse holder.
 Do Not Operate in an Explosive Atmosphere: Do not operate the
instrument in the presence of flammable liquids or vapors. Operation in such
environments pose a safety hazard.
 Do Not Remove Covers: The cover should be removed by ElMeasure's
qualified personnel only. Opening the cover is dangerous, because some
areas inside the instrument have high voltages.
 External Connection: Securely connect the protective grounding before
connecting to the product under measurement or to an external control unit.
If you come in contact with circuit, make sure to turn OFF the circuit and
check that no voltage is present.

Precautionary Measures to be taken while Wiring the Circuit:
Turn OFF the power to the circuit, when wiring the circuit. Connecting
or removing measurement cables while the power is turned ON is
dangerous.
Take special caution not to wire a current measurement circuit to the
voltage input terminal or vice-versa.
Strip the insulation cover of the measurement cable so that when it is
wired to the input terminal, the conductive parts (bare wires) do not
protrude from the terminal. It is recommended to use appropriate pre
lug after crimping the wire. Also, make sure to fasten the input
terminal screws securely so that the cable does not come loose.
Use cables with safety terminals that cover the conductive parts for
connecting to the voltage input terminals. Using a terminal with bare
conductive parts is dangerous if the terminal comes loose.
After connecting the measurement cable, attach the current input
protection cover for your safety. Make sure that the conductive parts
are not exposed from the protection cover.
Use the suitable star screw driver and apply optimum torque to
prevent damage to the meter terminals.
CAUTION : During normal operation of this instrument,
hazardous voltages are present at the rear terminals, which can cause
severe injury or death. These voltages are present throughout the
potential transformer (PT), current transformer (CT) auxiliary supply,
communication & Input / Output terminal. Installation, disconnection or
removal of the meter should be carried out only by qualified, properly
trained personnel, after de-energizing connected circuits. Improper
installation, including improper wiring and/or improper grounding will
void ElMeasure's warranty.

WARNING : When using a modem interface between the host computer and
any remote device(s), ensure that the host computer is not used to set the
BAUD RATE parameter of any selected device outside the working range of
the modem. Doing so will cause that meter to cease communicating. Reestablishing communication with that meter is possible through performing
the following:
1. Reset the baud rate of the remote device from its front panel to a
value within the working range of the modem.
2. Set the computer to communicate at the baud rate at which the
remote device has been set to communicate.

CAUTION : Before wiring, de-energize the PT secondary by
opening the circuit or removing the secondary fuse. Do not short the
PT secondary. All wiring must confirm to any applicable local electrical
codes/ engineering practices.
CAUTION : CT secondary circuits are capable of generating
lethal voltages and currents when open circuited with their primary
circuit energized. Standard safety precautions should be followed
while performing any installation or service on the device (e.g. shorting
CT secondaries, etc.)
CAUTION : Do not connect ground to the shield at both ends
of a segment. Doing so allows ground loop currents to flow in the
shield, inducing noise in the communication cable.

13. APPLICATION
It is a common phenomenon that the equipments/motors often break
down in any industry due to various reasons. Typically, the reasons could
be poor incoming power quality, improper/ floated earthing, Process
defects, loose connections in current route, poor safety measures,
unskilled operators, natural calamities (lightening, flood) etc., The
damages due to natural calamities is very hard to control by human
beings.
Process Integration
Integration of process parameters such as temperature, Oil level, RPM,
Pressure etc. giving greater flexibility to monitor them along with electrical
parameters.
Control Features
2 user defined potential free digital
output, upto 6 threshold parameters
with programmable trip time to
protect the equipment from electrical
abnormalities.

TROUBLESHOOTING
Due to programming error, site conditions, some problems can cause the
Meter malfunction. The fault symptoms and their remedial action for
correction is given below.
1. If the display does not turn ON:
a) Check that there is at least 80 volts available to the power supply (L and N
connections) on the Aux supply terminals. If the above steps do not solve
the problem, Contact ElMeasure or your local ElMeasure representative
and report the problem and results of the test.
2.
a)
b)
c)
If the voltage or current readings are incorrect:
Check that the Connection mode (star/delta) is properly programmed.
Check that the voltage and current ratios are properly set.
Check the output of the CT's and PT's being used.
3. If the kW or Power Factor readings are incorrect but voltage and
current readings are correct:
a) Make sure that the phase relationship between voltage and current inputs
are correct by comparing the wiring with the appropriate wiring diagram.
b) CT reversal can be observed by either seeing the phase wise kW. Negative
kW is shown where the current polarity is reversed, need to be corrected.
Model where kW information is not available, you may check Amps Phase
angle.
4.
a)
b)
c)
d)
If RS-485 communication does not work:
Check that the baud rate of the host computer/PLC is the same as Meter.
Check that the device ID of the meter are unique and should not replicate.
Check all communications wiring is complete.
Check that the number of data bits is set to 8, with one stop bit and even
parity.
If the symptom persists after performing the specified steps, or if the
symptom is not listed above, contact your local ElMeasure representative or
