The Jola pump control systems are used of starting or stopping threephase ac pumps which are to be controlled by level controllers (e.g. Jola float switches, immersion probes, electrode relays etc.). They include devices for protection of the motor winding, e.g. fuses and thermal overcurrent trips. A run-dry protection switch can also be connected. The operating condition of the pumps and response of the overcurrent trip are indicated by built-in indication. Manual control is fitted in addition to automatic control via level controllers. The pump control systems for 2 pumps incorporate a selector switch for manual changing of the order of operation of the pumps when using base-load and peak-load pumps. All components are installed in an insulated casing with a hinged cover.
