USER GUIDE
LED INDICATIONS
INT :
The INT LED provides optical output for calibration
verification as well as visual indication of energy integration.
The pulse rate is 1000 Pulses/kWh.
EXP :
EXP
LED gives the indication of reversal of one or
more CT connections or presence of negative power in any
or all phases. In such cases meter may not indicate the
correct energy consumption. The CT should be connected to
the meter with correct polarities.
NOTE :
For resetting active energy, user will be prompted the password. If correct password is entered, the user
will be able to reset all energy parameters. This password will be
a value which will be greater than the configuration
password by 1.
Pulse output from meter can be interfaced into a process
through a PLC for on line control of energy content in the
process.
If the PLC has a self excited digital input, external DC
supply is not needed.
The kWh pulse is also used to derive average kWh
information at the PLC.

Pulse output from meter can be used as alarm generator
or total energy controller by interfacing it with Pre
settable counter and control circuits (Contactors, Relay,
Trip Circuit).
The counter is loaded with the maximum energy
consumption. When count reaches setpoint it provides
output to control circuit to take appropriate action.
