2.3 ANNUNCIATOR MODULE
The Annunciator Module (AM) is the primary system status
indication point for the EPACO system. It provides a single
point for retrieving history as well as system status information
for all EPACO modules attached to the remote bus. This
module is typically installed in an area removed from the process
environment such as a control room that is constantly attended.
The AM is powered with 24VDC from the PSU. A single AM can
be connected to the power supply. The AM is capable of
communicating on the Status Bus for exchanging status
information and remote control of the outputs.
The AM is equipped with two push buttons that allows you to
access the various menus and three seven segment LEDs for
identification of the system status within the menus.
The AM is the customer interface for the EPACO system. The
following tasks are accomplished by the AM:
 Monitors all EPC’s, RC8’s and PSU connected to the Status
Bus and displays general status
 Provides a central location for history response
 Provides central location to connect computer and monitor
history for entire EPACO system
 Communicates system status via trouble relay for user
interface
 Real time pressure reading of the EPC’s CEREx pressure
transducers
