ACTUAL VALUES
A4 PRODUCT INFO
Measured values, event records and product information are actual values. Actual values may be accessed via any of the
following methods:
• Front panel, using the keys and display.
• Front program port, and a portable computer running the 745PC software supplied with the relay.
• Rear RS485/RS422 COM 1 port or RS485 COM 2 port with any system running user written software.
Any of these methods can be used to view the same information. A computer, however, makes viewing much more conve-
nient, since more than one piece of information can be viewed at the same time.
Actual value messages are organized into logical groups, or pages, for easy reference. All actual value messages are illus-
trated and described in blocks throughout this chapter. A reference of all messages is also provided at the end of the chap-
ter. All values shown in these message illustrations assume that no inputs (besides control power) are connected to the
6
745.
Some messages appear on the following pages with a gray background. This indicates that the message may not appear
depending upon the configuration of the relay (as selected by setpoints) or the options installed in the relay during manu-
facture. For example, no display associated with Winding 3 will ever appear if the relay is not configured for three-winding
operation.
