Description
Huawei UPSs, set this
parameter to Standard BSC.
After setting this parameter to
Standard BSC, you need to
set the two UPS systems in
the dual-bus system to BSC
master system and BSC
slave system respectively in
the BSC master/slave system
setting. (The two UPS
systems cannot be BSC
master systems or BSC slave
systems at the same time. If
you need to change the
settings in the future, perform
operations under the guidance
of maintenance engineers.)
NOTE
Ensure that the BSC signal cable
between the BSC master and slave
systems is properly connected and
that BSC-related hardware is
properly installed.
N/A
Set this parameter based on the
altitude of the place where the
rack is used.
Specifies the rack air filter
maintenance interval. If it is set
to 0, there is no reminder.
These two parameters enable the
UPS to control the interval that
each rack (or unit) transfers from
battery mode to normal mode,
which reduces the impact on the
generator or power grid. In the
case of battery undervoltage, the
system automatically shortens the
delay for transferring to normal
mode to 1/8 of the normal delay
to accelerate the transfer and
prevent battery overdischarge.
Intra-rack power unit start
delay (s) can be set to a value
ranging from 0.5 to 120.
Inter-rack power unit start
delay (s) can be set to a value
ranging from 2 to 120. The preset
