SHUN MK is intended for manual and automatic control of the pump of a water tower or sewer station when ensuring automatic protection of electric motors against emergency operation of work.
SHUN MK provides automatic protection of electric motors in the following emergencies:
- Current overload;
- Short circuit;
- Asymmetry of phase currents;
- Break of phases;
- Violation of alternation of phases;
- Long idling;
- Operation of emergency contact or sensor of the dry course.
The operating function SHUN MK provides:
― Automatic operating modes: water rise / drainage;
― Control of the pump electric motor on sensors of level/pressure or the electrocontact manometer;
― Control and indication of working current, the consumed active power, the feeding tension, current of zero sequence;
― Control and indication of emergency conditions of the electric motor and sensors;
