EMS 227 Description
|
The EMS227 Electronic Monitoring System / Controller is
micro-processor based for monitoring and control of equipment functions. Current
applications for the EMS227 include the following:
 | Center Pivot Irrigation Control |
| Wind Machine Auto Start |
| Timed Irrigation Control with Automatic Cooldown and Shutdown |
Operating data is displayed on a custom icon based liquid
crystal display. Operating parameters such as oil pressure, engine temperature,
engine speed, battery voltage, fuel level, and engine running hours can be displayed.
The EMS operating parameters are configured through a simple
three-button interface. Access to the system memory is controlled by an entry code. You
can change such parameters as shutdown set-points, operating delays, and throttle
parameters.
Standard Program Features
An on-board hourmeter keeps a log of equipment running hours.
Ramp Oil pressure monitoring protects equipment at both high rated speed and low idle
speed. Programs may also include some of these features:
| Basic start / stop |
| Engine warm-up / cooldown |
| Delay on start / stop |
| Automatic throttling |
| Prelube / glowplug functions. |
