Full Load Burn In Test
**************************************************************************
NOTE: Delete emergency source testing requirements
if no emergency source is available.
**************************************************************************
The installed system shall undergo an additional full load burn-in period
of 24 continuous hours. If a failure occurs during the burn-in period, the
tests shall be repeated. Instrument readings shall be recorded every half
hour as above. During the burn-in period, the following tests shall be
performed:
a.
With the UPS carrying maximum continuous design load and supplied
from the normal source, switch [100 percent load] [50 percent
load] on and off a minimum of five times within [the burn-in
period] [_____].
b.
With the UPS carrying maximum continuous design
load and supplied
from the emergency source, repeat the switching
operations
described in step a. Also, verify that the UPS
module rectifier
charger unit(s) go into the second-step current
limit mode.
c.
With the UPS carrying maximum continuous design load and operating
on battery power, repeat the switching operations described in
step a above.
d.
Continue operation on battery power for 1 minute, then restore
normal power.
The Contractor shall furnish a high-speed dual trace oscillograph to
monitor ten or more cycles of the above tests at the ON and OFF transitions
and two typical steady-state periods, one shortly after the load is
energized (at 30 to 60 seconds) and one after operation has stabilized (at
8 to 10 minutes). Four copies of the traces shall be delivered to the
Contracting Officer.
