A brownout occurs when an Input Undervoltage condition exists for more than 5 minutes. During this
time, Input Line Fail condition is not active. To determine the brown out count, highlight BROWN
OUTS and press SELECT. Once a count is made, allow 30 minutes to re-arm the counter.
The condition for blackout occurs any time all 3 phases of the input voltage sources falls below 60% of
the rated input voltage rating. The counter starts from the time the Liebert Global Services completes
the startup procedure, and signs off the SYSTEM STATUS Screen. The counter is automatically re-
enabled when all 3 phases of the input voltage source rise above the 60% limit.
The Accumulated Number Of Blackouts (Blackout Counter) can be viewed by highlighting BLACK
OUTS and pressing SELECT.
