Soft Reset After Editing
Changes to the device often require a Soft Reset before re-starting.
In this case, an inhibit becomes active in the background (Stopped
LED will start blinking). The inhibit screen will prompt the user soft
reset with RESET button. This prompt will not appear while in the
PRG menu because the user may want to set multiple items. See
Faults and Events section for more information on Inhibit screens.
MUI Fault and event diagnostics
Faults: When a fault occurs, the FAULT LED will light and a
notification screen will provide fault description and access to fault
diagnostics. Users can view the trip snapshot or fault queue from
the fault screen.
Figure 51. MUI diagnostics.
The FLT screen can be cleared by pressing OK, but the FAULT LED
remains lit. Clear a fault message by pressing RESET. If the fault
condition is no longer detected, the fault will clear and the RVSS will
reset.
A failed reset attempt is indicated by a blinking FAULT LED. This
means the reset command was received by the device but the fault
cannot be cleared because the condition is still present.
The active fault can also always be viewed via PRG | Faults and Events
| Active Fault.

Inhibits
An inhibit is a condition that occurs while stopped that will prevent
starting. This could be a fault condition or a parameter change that
requires soft reset or creates configuration conflicts.
When an inhibit occurs, the stopped LED flashes and an Inhibit
screen provides the reason. If an Inhibit is due to parameter changes
requiring soft reset, the notification screen will provide a button to
soft reset. If inhibit is due to a configuration problem, a button option
provides details about the problem.
Inhibit notification screens will not appear within the PRG menu as
the user may be changing multiple parameters and will only want to
Soft Reset once. The screen will appear if the user takes any of the
following actions:
1. Returns to the home monitoring screen by pressing MODE/
BACK. Pressing MODE/BACK once steps out of each menu
while pressing and holding will go immediately back to home.
2. Press the START button
3. Lets the idle timeout expire with "Return to Home Screen"
enabled in timeout behavior (User Interface Settings)
The active inhibit can also always be viewed via PRG | Faults and
Events | Active Inhibit
Figure 53. MUI inhibits.

pop-up screen for a warning. To view the active warning, go to PRG |
Faults and Events | Active Warning.
MUI user interface settings
The monitoring user interface offers a number of customizable
features. Navigate to PRG | User Interface Settings to view or change
