Active Power Monitoring - Siemens SIMOCODE pro Operating Manual

Active power monitoring

Description
SIMOCODE pro can indirectly monitor the state of a device or system via the active power.
For example, by monitoring the active power of a pump motor, conclusions can be drawn
from the active power level about the flow rate or fluid fill levels. The active power curve of a
motor is a precise reflection of its actual load across the entire range. Excess load results in
increased wear of the motor and, thus, may lead to premature motor failure. Insufficient
active power can, for example, be a sign of no-load motor operation.
SIMOCODE pro allows two-phase active power monitoring for freely selectable upper and
lower limits. The response of SIMOCODE pro when a prewarning or trip level has been
reached can be freely parameterized and delayed.
The active power is measured by means of current / voltage measuring modules.
