Description
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.
