EMS 448 Description

The EMS448 Electronic Monitoring System / Controller is micro-processor 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. This unit is comes in a NEMA 4X enclosure for use in outdoor environments. It is perfect for farming applications.

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 startup lockout are included.

Operating data is displayed on a 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 the time of last shutdown.

Standard Program Features

An on-board hourmeter keeps a log of equipment running hours and alerts you when to change oil, filters and perform other routine service. Ramp Oil pressure monitoring protects equipment at both high rated speed and low idle speed. The program features basic start / stop, engine warm-up / cooldown, delay on start / stop, automatic throttling, and prelube / glowplug functions.
