Description
An electronic control device called the motor protector MP 204 is created for monitoring and safeguarding machines, cables, and cable couplings.
The MP 204 protects against:
- Overload
- Dry running in pumping systems
- Incipient motor defect
- Too high motor temperatures
- Supply failure
Monitors the following parameters:
- System insulation resistance to earth before start
- Motor temperature- only possible if the motor is fitted with an operation Tempcon temperature transmitter, a Pt100/Pt1000 pr PTC sensor.
- Current consumption of unbalance
- Supply voltage
- Phase sequence
- Missing phase
