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. If the voltage or current readings are incorrect:
a) Check that the Connection mode (star/delta) is properly programmed.
b) Check that the voltage and current ratios are properly set.
c) 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. If RS-485 communication does not work:
a) Check that the baud rate of the host computer/PLC is the same as Meter.
b) Check that the device ID of the meter are unique and should not replicate.
c) Check all communications wiring is complete.
d) 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
the technical support / customer support department.
