RUN TIME DISPLAY
4.4.1
NORMAL
When first powered up and operating normally, the display will
show the current temperature, time, and date; the user configurable
monitor location and IP address; current AC line voltage and Red
Enable voltage; current communication port and/or Ethernet port
activity indicators; and monitor serial number, up time, and
firmware version.
From this screen the user can press:
ENTER
to access the Main Menu
ESCAPE
to access the Real Time Field Voltage Display
▲
to increase the front panel LED dimming level
▼ to decrease the front panel LED dimming level
◄ to access the Configuration Shortcuts menu
► to access the Troubleshooting Shortcuts menu
HELP
to access the context sensitive help system
4.4.2
FAULT
When a fault has been detected, the normal display will have the type of
fault and date/time the fault occurred overlaid on the bottom portion of
the screen and on an inverse background. Pressing
HELP
will display
information relevant to the current fault. Pressing
ESCAPE
will display
the field voltages latched at the time of the fault.
4.4.3
CHANGES PENDING
When the monitor detects that a configuration change has occurred that
should be logged, the monitor will begin to beep at a one hertz rate and
the Run Time display will indicate that changes are pending. These
changes will not be implemented until the changes are explicitly
accepted. This can be done by pressing and holding the
RESET
pushbutton for five seconds until the monitor gives five quick
confirmation beeps or navigate to the Fault Monitoring Menu and select
Save Changes.
4.4.4
UPGRADE PENDING
When new firmware has been downloaded in to the monitor, the Run
Time display will indicate that there is a pending upgrade and that you
need to cycle power to complete the upgrade process.

VOLTAGE DISPLAYS
Pressing the
ESCAPE
pushbutton at the Run Time display accesses the
Voltage Displays. There are four possible displays: Real Time Field
Voltages, Real Time Misc. Voltages, Last Fault Field Voltages, and Last
Fault Misc. Voltages. If a fault is currently displayed on the Run Time
display the Last Fault Field Voltages will be the first screen displayed.
These are the voltages on the inputs at the time of the fault. If there is no
fault then the Real Time Field Voltages will be displayed first and are
updated every 100 milliseconds. If the voltages for the last fault are
being displayed, a text box with the text “LAST FAULT STATUS” will
be displayed once every five seconds so that the user can easily
distinguish real time voltages from latched fault voltages.
From these screens the user can press:
ENTER
to return to the Run Time display
ESCAPE
to return to the Run Time display
▲
or ▼
toggle between field and misc. voltages
◄
or ► toggle between real time and last fault voltages
HELP
to access the context sensitive help system

MAIN MENU
Pressing the
ENTER
pushbutton at the Run Time display accesses the Main Menu. The currently selected menu
item will flash at a one hertz rate. To navigate to the selected menu item, press the
