Figure 3-3: Typical paging operation from Main Menu selection
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.
