GRUNDFOS MP204

The motor protector MP 204 is an electronic control unit designed for monitoring and protection of motors, pumps, machines, cables and cable joints.
The MP 204 monitors the following parameters:
•System insulation resistance to earth before start
•Motor temperature. Only possible if the motor is fitted with an operational Tempcon temperature transmitter, a Pt100/Pt1000 or a PTC sensor
•Current consumption and unbalance
•Supply voltage
•Phase sequence
•Missing phase
•Power factor (cos phi)
•Harmonic distortion
•Starting capacitor (single-phase operation only)
•Run capacitor (single-phase operation only)
The MP 204 protects against:
•Overload
•Dry running in pumping systems
Incipient motor defect
•Too high motor temperature
•Supply failure
As standard, the MP 204 incorporates:
•A display for reading values, such as current, voltage, temperature, cos phi, warning and trip codes
•Relay output for external fault indication
•GENIbus connection
Pt100/Pt1000 sensor input
PTC/thermal switch input
