Press SELECT to advance to the System Fault screen.
The System Fault screen indicates any failures in the primary system or the redundant
back-up system. All internal power supplies are monitored (24V, +8V, -8V, 5V) on both the
primary and back-
up systems. A failure on one of these supplies will be indicated with a “PS
FAIL” fail warning for either system. A communication failure would be indicated by a “Com
FAIL” indicator. Either of these fault statuses will result in the change of the primary to the
backup system. The individual statuses of the internal power supplies are also available via
the RS232 serial port.
The presence of a valid DC input voltage is indicated on this screen, as well as a valid AC
power input. If either of these supplies are not present, a “FL” indication will be shown next
to the appropriate input.
2.11 UTC Mode
The user can select how the time is displayed on the screen by choosing between three
formats: UTC, 24 hour mode, or 12 hour mode. Toggle through the modes by pressing the
SELECT button.
If 24 hour mode or 12 hour mode is chosen, the GMT offset will be applied to the displayed
time. If GMT mode is selected, no offset will be applied to the displayed time.
2.12 GMT Offset
With 24 hour mode or 12 hour mode, the user can choose to align the displayed hour with
their current time zone. Using the SELECT button, toggle to the desired offset. The offset
will decrement through the 24 hour period, from UTC-11 to UTC +12, etc.
