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 

This section defines how to navigate through the EMS PRO LITE user 
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.
