When the display shows SETPOINTS, pressing the MESSAGE ► key or the ENTER key will
display the page headers of programmable parameters (referred to as setpoints in the
manual). When the display shows ACTUAL VALUES, pressing the MESSAGE ► key or the
ENTER key displays the page headers of measured parameters (referred to as actual
values in the manual).
Each page is broken down further into logical sub-pages of messages. The MESSAGE ▲
and MESSAGE ▼ keys are used to navigate through the sub-pages. A summary of the
setpoints and actual values pages can be found in the Chapters : Setpoints and Actual
Values, respectively.
The ENTER key is dual purpose. It is used to enter the sub-pages and to store altered
setpoint values into memory to complete the change. The MESSAGE ► key can also be
used to enter sub-pages but not to store altered setpoints.
The ESCAPE key is also dual purpose. It is used to exit the sub-pages and to cancel a
setpoint change. The MESSAGE ◄ key can also be used to exit sub-pages and to cancel
setpoint changes.
The VALUE keys are used to scroll through the possible choices of an enumerated setpoint.
They also decrement and increment numerical setpoints.
The RESET key resets any latched conditions that are not currently active. This includes
resetting latched output relays, latched Trip LEDs, breaker operation failure, and trip / close
coil failures. The Autoreclose Scheme is also reset with the shot counter being returned to
zero and the lockout condition being cleared.
