Description
The EMS447 and EMS448 Electronic Monitoring Systems/Controllers are 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. 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 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 time of last shutdown.
Basic 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. For instance, based on engine manufacturer’s requirement, shutdown could occur at 30 lb. (207 kPa) pressure at 1800 RPM or at 5 lb. (34 kPa) at 600 RPM or any shutdown point in between.
Basic Models
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. Refer to “Accessories” on the back page.
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. See “Optional Accessories” on reverse side.
