The EMS447 and EMS448 Electronic Monitoring System / Controller are microprocessor based for monitoring and control of equipment functions. The basic EMS system is programmed for a typical industrial engine power unit. Custom programming is available to adapt the EMS to a wide variety of engine and equipment requirements.


Basic programs provide auto-start/manual start and first-out shutdown for engine functions such as pressure, temperature, level and overspeed. Necessary time delays for start up lockout are included. Operating data is displayed on 32 character back lit alphanumeric liquid crystal display.


The EMS operating parameters are configured through a simple three-button interface. Access to the system memory is controlled by entry codes.


A password-protected program uses built-in memory to display the alarm/shutdown history, including a display of the last ten shutdowns, when and why they occurred and displays all of the engine operating conditions at time of last shutdown.



EMS448 has an extruded aluminum enclosure suitable for panel mounting. Wiring is via optional wiring harness. Relay boards are available for additional relay contact capability.


EMS448 has a NEMA 4X type enclosure. Wiring is connected directly to the relay board terminal block located within the enclosure. Relay board for additional relay contact capability is available.
