Event Log
Mask Meaning and Corrective Action(s)
The maximum heat sink temperature limit
has been exceeded. (Should be preceded
by a "Heatsink" Overtemp Warning alarm).
The load will be transferred to the Static
Bypass if available. If the load was already
on SBS when this alarm occurred, the
system will shut down. The fault will clear
YES YES when the temperature falls below the
Heatsink Overtemp Warning threshold. (If
this fault doesn't clear soon enough it will
lead to an "Overtemp Time-out Shutdown").
If the unit is still running it will make an
attempt to auto-retransfer when the fault
clears. If the faults do not clear; contact
Liebert Global Services.
The input source is present, but the input
power supply has failed. The unit has
NO YES redundant power supplies on both the input
and the output. Contact Liebert Global
Services immediately.
The output source is present, but the output
power supply has failed. The unit has
NO YES redundant power supplies on both the input
and the output. Contact Liebert Global
Services immediately.
The Outlet air temperature has exceeded
its maximum set point. The UPS will
transfer the load to bypass if available. If
already on bypass the system will
shutdown. The fault will clear when the
temperature falls below the Outlet Air
Overtemp Warning threshold. (If this fault
doesn't clear soon enough it will lead to an
YES YES
"overtemp Time-out Shutdown".). If the unit
is still running when the fault clears it will
auto retransfer to UPS. Check all air inlets
and exhausts for blockage and check the
air filter. Check the actual load against the
UPS rating. Remove any excess load.
Contact Liebert Global Services if the alarm
persists.
Failure of this fuse will remove control
power. The UPS will attempt to transfer to
Static Bypass if available. Locate the cause
NO YES
of any failure, before replacing a fuse or
Contact Liebert Global Services
Immediately.
UPS will transfer to Static Bypass if
available and shut down the UPS. Start-up
NO YES
will be inhibited. Contact Liebert Global
Services.
