Protection Functions
The MP 204 provides comprehensive monitoring options to protect your pump system:
Overload/Underload Protection If the motor current falls outside required values, the motor stops automatically. Protecting against overload and underload conditions lengthens pump lifetime and improves overall system reliability.
Temperature Monitoring The motor shuts down before it overheats, providing early warning for servicing requirements. Compatible with TempCon temperature transmitter for SP pumps, and Pt sensor or PTC/thermal switch for other pump ranges.
Power Consumption Monitoring Continually checks the motor’s power consumption and stops the pump if power falls below a certain level. This indicates potential problems and prevents total motor damage that would occur if the pump runs dry.
Overvoltage/Undervoltage Protection Monitors voltage variations that may be caused by long cables or transformer issues. Early warning enables improvement of operating conditions before pump damage occurs.
Ground Failure/Insulation Resistance Measures voltage leakage to ground on start-up, protecting against ground failure before the pump starts. The pump will not start if issues are detected, averting potential damage.
Phase Sequence Verification Ensures correct phase sequence for maximum performance. Incorrectly connected phases cause rotation in the wrong direction, reducing performance and causing excessive wear.
Phase Missing Detection Checks that all phases are present, often identifying wear, mains cable faults, or blown fuses. Ensures the pump is correctly installed, avoiding overheating and possible motor damage.
Power Factor Monitoring The power factor indicates whether the pump runs under optimal conditions. A fall in power factor may indicate intake clogging or impeller wear, signaling that preventive maintenance is required.
Additional Monitoring Parameters
The MP 204 also monitors:
- Harmonic distortion
- Run and start capacitor (single-phase motors)
- Operating hours
- Number of starts
Compatible Pump Ranges
The Grundfos MP 204 is designed for use with:
- Grundfos SP – Submersible borehole pumps
- Grundfos CR – Vertical multistage pumps
- Grundfos NB/NK – End-suction pumps
- Grundfos TP – In-line circulation pumps
- Grundfos BM – Submersible motors
As a standard motor protection unit, the MP 204 also provides excellent protection for any motor requiring comprehensive safeguarding.
