Description
Indicates this parameter controls the
time-of-day (TOD) when a battery string pair
moves from the load bus to the charge bus.
The default value is 23 and corresponds to
11:00 P.M.
Indicates this parameter controls the amount
of time a battery string remains on the charge
bus
Indicates this parameter controls the amount
of time a battery string connects to the
discharge bus. The battery string is connected
to the discharge bus during the weekly
discharge test. The default value is 4 and
corresponds to one hour.
Indicates this parameter controls the minimum
voltage a battery string must be at to rotate to
the charge bus. The default value is -420 and
corresponds to -42.0 V.
Indicates this parameter is the comparison
value for the voltage of the battery string
during the open circuit test. The default for
Yuasa NP24-12 and Eagle-Picher A0386201
batteries is -504 and corresponds to -50.4V. If
this parameter is set to zero, the open circuit
test does not occur.
Indicates this parameter is the comparison
value for the voltage of the battery string during
the discharge test. The default value for Yuasa
A037761 and Eagle-Picher A0386201
batteries is -495 and corresponds to -49.5V. If
this parameter is set to zero, the discharge test
does not occur.
