Battery condition test
(BCT)
Battery reverse connection will open internal
fuse (and produce alarm)
Detects for presence of battery on start up,
then every 60 minutes when charge current <
200mA
Electronic circuit breaker (ECB) operates
under the following conditions:
•
battery voltage drops to 1.67V/cell
-
auto reset
•
< 300ms for load > 6 x rated PSU cur-
rent, allows ~1.5x rated PSU current
from battery without acting,
•
< 2ms, backed up by fuse
Green:
Battery System OK, Power OK
Red:
Standby
•
Power OK (mains or charger fail, standby
mode)
•
Battery System OK
-
battery voltage low
(on mains fail) , battery missing, battery
circuit wiring faulty, BCT fail (if enabled)
