Figure 91 Warning history
Figure 92 Fault history
The warnings, fault meanings and possible causes in the following text and in Table 15 may be used
in troubleshooting the messages and may also aid in identifying conditions outside the flywheel sys-
tem that may adversely affect it.
8.2 Warnings
A Warning is an indication of an abnormal system condition significant enough to warrant being
annunciated and logged. Warning conditions may indicate that a system parameter is out of its nor-
mal operating range, or may signal an external problem. A Warning indication is for information only
and does not require any operator intervention for continued operation of the unit. While in Warning
condition, normal operation of the unit will continue unimpeded. A warning can indicate an operating
condition that warrants observation and may require preventative maintenance.
Figure 93 Warning screen
The Warning condition is indicated by the System Status field displaying “WARNING” in the Control
Panel window (see Figure 93). If one Warning is present, the Warning Label (see Table 15.) will be
displayed.
While the Warning condition exists, and if more than one Warning is present, F5 the “More Info” key
will be enabled in the Control Panel window. If pressed, the separate Warning Labels will be dis-
played in the Control Panel window.
Any of eight warnings could occur while the Liebert FS is operating. Warnings give advance alert of
potential problems and schedule service and preventive maintenance. These can be monitored and
investigated through the use of data from the Control Panel and system tests.
