Operating procedure:

IR-SHUN pump control cabinet has two control modes – manual and automatic. Control mode is selected by switching the mode selector to the required position.In manual mode the pump control is performed from the front panel of the cabinet with buttons "Start" / "Stop" of the respective pump, status indication is displayed.In automatic mode – from signals of external sensors.

Operational principle of the cabinet is based on cascade control diagram, from the signal of feedback sensor (pressure, flow rate, temperature, level, pressure fall, etc.).
