Appendix C.3 VIB Operation
Upon Initial System Startup of the Liebert FS by a Liebert-certified service technician, your VIB will
be operational. There is nothing to turn on or configure. Make sure that all external connections to
the VIB are made with the Liebert FS power off. Making connections while power is applied may have
undesirable effects and may damage the equipment.
Appendix C.3.1 VIB Operational States
The operational status of the VIB is indicated on the main screen of the Display Panel. There are
three possible states: “Enabled”, “Disabled” and “Not Available”. They are indicated on the Display
Panel by “1,” “0” or “NA,” respectively.
“Enabled” State
If the VIB is detected when the system is powered-up or rebooted, it will automatically be enabled. If
for any reason the VIB has been disabled, it can be re-enabled by pressing F6 (Setup Parameters),
then F3 (UIB Enable). While the VIB is enabled, the “Start,” “Stop” and “Clear Fault” buttons will not
be visible on the Display Panel. To control the Liebert FS from the Display Panel, the VIB must first
be disabled.
“Disabled” State
If the VIB is not detected when the system is powered-up or rebooted, it will automatically be dis-
abled. At any time during operation the VIB can be disabled by pressing F6 (Setup Parameters), then
F3 (UIB Disable). When the VIB is disabled, the inputs are ignored and all outputs are turned off.
Before disabling the VIB, consider how disabling the board will affect other system components.
“Not Available” State
The Liebert FS continually monitors the status of the VIB to verify that it is operating correctly. If the
response from the VIB is not what is expected by the Liebert FS, “WARNING” will be displayed on
the front panel.
