2.2 PXR 25 and 20D display with keypad
The PXR 20D and PXR 25 user interface (UI) has a display and keypad on the front of the
trip unit. This display provides information regarding the operation of the trip unit and the
method to select configuration options. The keypad provides for navigation through the
menu structures. Information is presented on the display in English, Chinese, German,
Spanish, or up to two additional languages (loaded by PXPM). To provide for easier reading
of the display with the circuit breaker mounted on its side, the display is configurable to
rotate 90 degrees left or right.
There are three navigation buttons near the display used to control the information shown on
the display and to select configuration options:
Up arrow button
- Used to move up in the menu display screen or increase an adjust-
ment value.
Down arrow button
- Used to move down in the menu screens or decrease an
adjustment value.
Enter button
- Used to enter a menu or configuration setting or to go back to the
previsions menu.
Each trip unit style has configurable settings
for protection and other features. All can be
configured using either the front panel or by
using PXPM software. Details regarding the
available protection settings for each frame are
found in Section 9: Available protection settings.
When the PXR trip unit is initially powered-up,
the display will briefly show a loading screen
and then change to the main menu. During
this time, the trip unit is already functioning and
performing protection operations. Depending
on the trip unit style, there are up to 12
submenu selections from the main menu.
Each is accessed by pressing the down arrow
or up arrow buttons to highlight the appropriate
submenu, then pressing the enter button
