Troubleshooting

8.3Faults

A Fault is defined as an undesirable system operating condition that could cause further damage to the system or potentially drop the load. Once detected, Faults may trigger an appropriate emergency action such as shutting the unit down. Most Fault conditions are automatically taken care of by the Liebert FS control system and require no Operator intervention. A few Fault conditions may be resolved only through operator intervention or service by a Liebert technician.

A Fault condition must be valid for a certain amount of time before it is recognized as an active Fault. This prevents spurious signals from causing false Fault detection and unnecessary state changes. Figure 93 shows the appearance of an active Fault on the main screen.

While in Fault condition, normal operation of the unit is suspended, the operation of the Power Con- version Module is paused, and the unit transitions into FAULT Mode, where it waits for one of the fol- lowing to occur:

1.The condition to clear the fault [AUTO CLEAR]

2.The unit to automatically transition in SHUTDOWN Mode [AUTO SHUTDOWN]

3.Operator action [OPERATOR CLEAR].

The Fault condition is indicated by the System Mode displaying “FAULT” in the Control Panel win- dow.

If there are multiple Fault conditions present, the F5 “More Info” key will be enabled in the Control Panel window. If pressed, information related to the specific Faults will be displayed in the Control Panel window (see Figures 54 through 56). If there are multiple faults they will both be displayed by pressing the F5 “MORE” button.

In many cases, when FAULT Mode is entered, the Fault may be cleared by pressing the F3 “CLEAR FAULT” button on the Control Panel or utilizing the VIB option - if enabled - to send a “CLEAR FAULT” signal to the system. In order to “CLEAR FAULT” the operator must be in proper security access level; User or above. Table 16 describes the fault labels, meanings and possible causes for the
