Electronic Monitoring
System/Controller
Description
The EMS547 Electronic Monitoring System/
Controller is micro-processor based for monitoring
and control of equipment functions. It is especially
suited to tasks requiring remote modem or SCADA
communications. Four built-in communication ports
provide a variety of communications capabilities.
Basic programs provide selectable auto or manual
start/stop and first-out shutdown for engine functions
such as pressure, temperature, level and overspeed.
Time delays for lockout during start up are included.
The EMS547 can be applied as an RTU to inter-
face between SCADA applications and other con-
trol platforms. It can also be used, in conjunction
with a Hayes compatible modem (9600 Baud), for
remote communications.
An external PC Card reader can be used with the
EMS547 to log data from flow meters, pressure
transmitters, electric gage senders, and other sens-
ing devices. This is a popular application in the
flood control market.
Operating data is displayed on a 32 character back lit
alphanumeric liquid crystal display. An on-board
real-time clock keeps a log of equipment running
hours and alerts you when to change oil, filters and
perform other routine service.
The EMS547 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.
Because of the flexibility of this product, please call
one of our application specialists to see how best to
apply the EMS547. We have a growing library of
standard programs or we can write a program to your
specific needs.
