EMS Pro Controller
The EMS PRO is a dedicated, micro-processor-based single-engine controller, with field-adjustable operating parameters that can be changed without the need for a laptop computer. An all-in-one customizable unit that meets the needs of engine-driven pumping equipment applications. It’s both rugged and flexible, designed for use across multiple engine lines, yet able to support both mechanical and J1939 electronic engines. For quick and accurate troubleshooting, the controller displays vital engine and equipment information including diagnostic codes, first-out shutdowns and/or alarms. It stores the last 10 engine shutdowns with a date-and-time stamp, and records engine and system information at the time of shutdown.

The EMS PRO is ideal for use with a remote modem or in a SCADA system offering Modbus RTU protocol on either the RS232 or RS485 port. The controller has selectable auto start/stop features with several throttling options, as well as manual operation. The auto start/stop options (Single Contact, Floats, Momentary, Transducer and Clock) are available at the touch of a button. As an example, the Transducer start/stop option includes three settings: pressure, level and temperature. In addition, there are many performance-enhancing features, all of which are available through a back-lit operator interface that is readable both day or night and very easy to use.

Able to withstand a wide ambient temperature range, the EMS PRO comes standard in a polycarbonate NEMA 4 rated enclosure secured by four rubber shock mounts. Inside is a backlit graphical display visible in all types of conditions. Easily accessible touch buttons and a large, clear cover round out the compact, fully functional control unit. Operators can choose from many start/stop and throttling options, as well as manual starts and throttling with very basic training on both mechanical-control and electronic-control engines. Auto-start and time-stamping are quickly accomplished through the easy clock set-up. Other built-in functions include auto-start, engine running with no operator present, engine throttling to demand (pressure or level), service reminders and TSC1 speed control messages. For easy field wiring, the EMS PRO has two (2) Deutsch HDP connectors, 21 pin and 31 pin.
Communications
The EMS PRO has RS485, RS232 and J1939 CAN communication ports. The standard unit uses RS485 or RS232 for Modbus RTU. At the same time, the CAN port allows J1939 communication with the engine ECU to display engine parameters and control the throttle via TSC1 if supported by the engine.
