Microprocessor MPZK-150 device of protection and control of the pumping unit and protection of the electric motor of the pump
Automatic control provides:
- Automatic and manual control
- Operating mode - water rise or drainage
- Inclusion/shutdown of the electric motor on signals from level detectors or other sensors.
- Control and indication of working current of the electric motor.
- Control and indication of alarm status.
- Possibility of connection in uniform system of scheduling via the built-in RS-485 interface under the Modbus RTU protocol.
The emergency shutdown occurs at emergence:
- Inadmissible overcurrent conditions at the time of start-up and in operating mode.
- Break of one or two phases.
- Asymmetries of power voltage.
- Idling of the electric motor.
- Electric motor stator winding overheat.
