In addition to the motor control parameters the
system can be expanded to include pump
monitoring parameters such as bearing
temperatures, flow, pressure and vibration. This
information could be used to provide the
efficiency of the pump thereby giving early
warning as per the health of the pump as well as
the ability to decide when the pump should be
maintained or rebuilt. Energy usage per
pump/efficiency per pump can also be derived
from this information.

energy faults
PROFITABILITY
The system is designed to meet the following
criteria:
• Low initial cost
• The option to add this to existing motor
starters and enhance the information
available
• Fast implementation as only plant specific
screens need to be developed
• Historical data capability to provide
information to assist with maintenance and
plant availability by providing out of norm
information and alarm information on SMS
or email or smart phone connections
