6.2.10 Noise Current
This screen allows user to set low noise
current cutoff. The range for this value is 0 - 30 %
of nominal value. By default it is set to 0 %.
6.2.11 Energy Output
With this value, the user can set the desired
energy measuring unit Wh, kWh or MWh. The
setting options are 1, 2, or 3, which identifies
the unit as described in the table below.

3
MWh
Note: The energy measurement in the "Wh" unit is blocked at a rated
power of > 60 kW. The meter automatically switches to "kWh" if this
condition is true.
6.2.12 Energy Digit Reset Count
This screen allows the user to set the maximum
power points before starting at zero. The options
for this setting are 6, 7 or 8 digits.
6.3 Selection of Communication Parameters
Various communication parameters are selected
in this display, for example "address", "RS485
parity", "RS485 baud rate". These settings apply
only to Modbus.
6.3.1 Address Setting
In this display, the user can set the Modbus
communication parameters for the devices.
The range allowed for the address is 1 to 247.
6.3.2 Baud Rate
In this display, the user sets the baud rate of
the RS485 port. The options for this setting
are 4800, 9600, 19200, 38400, and 57600.
The default value is set to 9600.
6.3.3 Parity
In this display, the user sets the parity and
number of stop bits of the RS 485 port. The
options for this value are as follows.
no1:
no parity, 1 stop bit
no2:
no parity, 2 stop bits
even:
even parity, 1 stop bit
odd:
odd parity, 1 stop bit
By default, the value for this parameter is set as no1.
6.4 Reset Parameter Selection
This screen allows the user to reset various stored
parameters. When the reset is performed, the current
register values are moved to corres-ponding "old"
registers. The various reset parameters are listed below.
none:
No parameter is reset
All:
All parameters are reset
on-hr:
On hour is reset
intr:
Interruptions is reset
hi-V:
Higher voltage is reset
Lo-V:
Lower voltage is reset
hi-A*:
Higher current is reset
Lo-A*:
Lower current is reset
EnEr*:
Energy is reset
dMd*:
Demand is reset
A-hr*:
Ampere hour is reset
r-hr*:
Run hour is reset
CHAn*:
Selected channel data is reset
* These parameters reset channelwise.
6.5 Output Parameter Selection
In this menu the user can configure the output
parameters available in the measuring device.
6.5.1 Select Relay Output
On this screen the user can select relay as the
output option and can decide which of the available
relay to be used for his/her application.
On selecting a relay, the user will be taken to the
type selection screen, which prompts him to select an option out of
seven available. The options are as following.
1. 0 = None
4. 3 = Timer
2. 1 = Limit
5. 4 = Remote
3. 2 = Pulse
6. 5 = Reverse Lock
The "none" option implies that the relay is disabled.
6.5.1.1 Limit Relay Configuration
These parameters will decide the operation of limit relay.
6.5.1.1.1 Limit Parameter
The user can assign any one out of available
options for limit relay.
