Utility functions of the controller
• Professional attempt to launch the pump after its emergency exclusion by one of the protective functions. For different emergency situations - different activation time.
• Possibility of calibration and change of calibration of the controller to cooperate with a given pump.
• Turn on and off the pump depending on:
About the water level in the tank from which we pump,
About the water level in the tank to which we pump,
with the pressure value in the tank to which we pump,
• Possibility to work in automatic or manual mode.
• Different signal sources owned by: probes, floats, pressure sensors
Controller's protective functions
• Double protection against dry -work Imported with:
with fluid levels/sensors,
on the analysis of the consumption of the working current of the pump,
• Protection against overload,
• Protection against a voltage drop,
• Protection against voltage jumping,
• Protection against overvoltage,
• short -circuit protection.
Additional functions M21
The M21 controller also has:
• the function of displaying the accumulated pump working time,
• The function of displaying the history of the last five failures in which protective functions worked,
• Dynamic LCD screen displaying the current state of the pump.
