Parameter
V out = Output Voltage
V pres = Voltage threshold for battery de-
tection & battery condition test (BCT). If
voltage drops to this level during BCT then
the test is aborted and BATT SYS OK
alarm activated. .
V shutd = Output voltage of PSU during
battery detection & BCT
V batl = voltage where BATT low alarm
activates during mains fail
V disco = Battery disconnect level on low
voltage during mains fail
Bccl = Maximum charge current as % of rated PSU rated current
Comms = communications mode of PSU: F = continuous data stream of status
BatDetect = Battery detection interval time, active only when no battery charge current is detected (the
unit may not detect a missing battery for up to this time)
BCT = length of battery condition test
Ret = retest option: N = after a failed BCT further scheduled BCTs are inhibited
Y = after a failed BCT further scheduled BCTs will be allowed
CC = Length of charge cycle in minutes/hours/days. ie. time between battery condition tests
MfiBCT = time before mains fail check during BCT. A mains fail during a BCT will stop the BCT. If set
longer than BCT time no mains fail check will occur.
*1 Except for 12V which is set at 50%

BATTERY CONDITION TEST

The BCT function is enabled by an internal jumper as supplied
from factory unless otherwise requested. Refer to the photo to
the right for the position of this jumper. It must be removed to
disable the automatic BCT. Although the BCT may be enabled/
disabled via the communication port, this software determined
state is not retained if the PSU is disconnected from both the
mains input and the battery.
BCT FAIL RESET
If the system fails a battery condition test the BATT LOW alarm
latches (de-energized state) until
either: both the mains power input and the battery are discon-
nected briefly
or:
the system passes the next BCT.
