Event Log
Mask Meaning and Corrective Action(s)
With the Batt Gnd Fault option installed and
the batt breaker closed, the DSP sees its
NO YES
BGF input asserted by the SWGR. No
action required.
With the Auxiliary temp sensor installed, it
NO YES is reading 85% or more of the specified
Maximum Aux temperature set point value.
With the battery breaker closed the battery
NO YES has exceeded the "Battery Temperature
Alarm Threshold" set point value.
Sensors on the power semiconductor
heatsinks detect temperatures above the
steady state limits for these components.
The control logic sets off the alarm but does
not shut down the UPS module if the
NO YES
condition lasts less than 10 minutes. Check
the air intake, air exhaust, and filters.
Reduce the load or transfer it to bypass.
Contact Liebert Global Services if the alarm
persists.
The intake air to the UPS module exceeds
the specified maximum temperature. This
condition only causes an alarm, but should
NO YES be corrected immediately to prevent
equipment overheating. Check to make
sure nothing is blocking the inlet air and that
the air filter is clean.
The Outlet air temperature has exceeded
NO YES 85% of its "Maximum outlet air temperature"
limit.
A fault in the designated Fan motor has
occurred. This condition only causes an
alarm, but if not promptly corrected it could
cause an equipment over-temperature
NO YES
condition that would shut down the UPS
Module. Check the Fans for proper
operation. Contact Liebert Global Services
if you require assistance or to replace a fan.
