Introduction

The EMS PRO LITE is a customizable pump-controller designed with

dewatering and irrigation applications in mind.

EMS PRO LITE offers field-adjustable operating parameters without the

need for a laptop computer. It can support both mechanical and J1939

electronic engines.

This unit offers selectable auto start/stop with auto-throttling options:

Floats, and Transducer. A backlit operator-interface offers many easy-to-

use performance-enhancing features. The display is readable day or

night.

The EMS PRO LITE is ideal for use with a remote modem or in a

SCADA system offering Modbus® RTU protocol on either the RS232 or

RS485 port.

NOTE: Your EMS PRO LITE must be modified to use these

ports – changes include additional wiring and enclosure

modifications.

User Interface and Navigation

interface. It explains the screens and keys used to modify settings and

how each works.

Membrane Keypad

The membrane keypad is made up of eight buttons. All of the functions

for the EMS PRO LITE can be set using these eight buttons.
