Dimensions

4 Operating Modes

The E30 MK2 includes 16 unique functions selectable across 4 operating modes — loss-of-prime, pressure guard (high/low), single-point snap-action, and dual-pump control. Different functions are available in different modes; see the printed data sheet PDF below for the full mode × function matrix.

3-Phase Pumping Systems

The E30 MK2 can be used to control either single-phase or 3-phase pumps, provided a 220–240 V AC or 24 V AC supply is available at the installation site. For 3-phase motors the E30 drives an interposing contactor — use the Pump Controller Power Calculator to size the contactor and verify cable rating + voltage drop.

Application Restriction

The E30 MK2 is an industrial control device, specifically designed for use in industrial, agricultural and mining applications. It must never be used for any other application. Installation must be carried out by a qualified pump engineer, and all electrical work by a licensed electrician.

Hazardous Areas

The E30 MK2 is not certified for use in hazardous areas and must not be installed in any area classified as hazardous under AS/NZS 60079.10 (Zone 0, 1, 2, 20, 21 or 22).

Maintenance

Le pressostat numérique E30 MK2 n’est pas entretenable par l’utilisateur. Toutefois, des pièces de rechange sont disponibles auprès de Kelco Engineering ou de votre distributeur.
