Modbus TCP. Be sure to write down the new IP address as you
will lose communications once saved.
• RTU slave configuration – For setting of address if used as a
Modbus RTU device
• Real time refresh interval – Time interval for the web page to
refresh real time date
• Device description – For naming of the system
• Panel configurations to include:
• Demand sub interval – Number of measurements taken
in the sub interval
• Sub interval length – Time between intervals
• Voltage mode – Delta or Wye
• Line to Neutral / Line to Line voltage depending on
voltage mode
• Potential Transformer (PT) Primary voltage – Secondary
preset to 120

Data available from this page –
• Firmware version
• Serial number of the controller
Global settings – Global settings will be applied across all the
meters in the system. Each meter can be customized in the
Branch meter configuration screen. The alarms are for the meters
and not meter modules. Individual phase alarms can only be set
for single pole meters. Alarm delays are time settings where the
meter is in alarm condition before the alarm flag is set. This is to
prevent momentary conditions sending alarm flags.
Multi-pole circuit breaker configuration – This page is used to
configure the meter modules into meters. The bottom of the page
displays those meters configured from the bottom of the page. The
meter configuration is drag and drop from the available module
column to the different meter configurations (1, 2 or 3 pole). Note
that modules have to be mounted contiguously in the racks to be
configured as multi‐pole meters.
Branch meter configuration – This page allows for
customization of the configured meters. Custom alarms may
be set that override the global alarms as well as naming of the
individual meters.
Real time data – This screen gives an overview of the alarm
status of the configured meters and allows for clearing of
the individual meter alarms. Clicking on the individual
meters will display that meters real time information to the
right of the grid.
User profile – This page is accessible to all users who can
modify their details except the ‘User ID’ and ‘Access Level’.
User ID and Access Level are set by the Supervisor only from
the User management screen.
User management – This page is accessible to ‘Supervisor’
user who can manage users’ accounts that includes adding,
removing and modifying the users. There are three levels of
users available:
• Supervisor – Has the ability to see all data and modify
setting and clear alarms and add or modify user settings.
• Controller – Has the ability to see all data and to clear
alarms. Controller cannot see or modify user
management.
• Observer – Has the ability to see data but is not allowed
to modify or clear alarms.
Diagnostics – This page is accessible to ‘Supervisor’ user.
The SEM3 metering system can work with supervisory
systems such as WinPM.Net, Power manager and other
SCADA or Building management systems that use Modbus
protocol. The Modbus registers for this product are such that
configuration using the controller web interface is not
absolutely necessary, but by doing so valuable time can be
saved.
1) Some applications will allow for more than 45 poles in one enclosure by adding a
second controller. Two controllers can monitor up to 90 poles.
