Description
Enable this parameter if a top
outlet fan is configured. Then the
fan running status can be
checked.
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 module) 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. The start delay of
a module in a rack varies
depending on the rack number
and module number. #1 module
in rack 1 does not have a start
delay.
The short-distance battery
temperature sensor monitors the
ambient temperature near
batteries, and ensures that
batteries work reliably and
securely.
Indicates whether the BCB trips
when the system stops supplying
power and the output power is
off.
