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.

8.2Warnings

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.

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.
