Measured values, maintenance and fault analysis information are accessed in the actual
values. Actual values may be accessed via one of the following methods:
1. Front panel, using the keys and display.
2. Front program port and a portable computer running the EnerVista 489 Setup
software supplied with the relay.
3. Rear terminal RS485 port and a PLC/SCADA system running user-written
software.
Any of these methods can be used to view the same information. However, a computer
makes viewing much more convenient since many variables may be viewed
simultaneously.
Actual value messages are organized into logical groups, or pages, for easy reference, as
shown below. All actual value messages are illustrated and described in blocks throughout
this chapter. All values shown in these message illustrations assume that no inputs
(besides control power) are connected to the 489.
In addition to the actual values, there are also diagnostic and flash messages that appear
only when certain conditions occur. They are described later in this chapter.
