ELECTRONIC CIRCUIT BREAKER (ECB)
The ECB is activated under the following conditions:
The ECB will latch open only when there is no mains input present. It will reset when mains power is restore or can be
manually reset by following the procedure in step 6 on page 8 of this manual.
Specifications are subject to change without notice. No liability accepted for errors or omissions.

=On =Flashing
System Normal: AC power is on, PSU output is OK, battery circuit is OK and bat-
tery voltage is > V Battery Low.
Battery Detection test in progress / imminent (LED begins flashing 10 sec. prior
to test of < 1 sec).
System AC power is on, PSU output is OK but either:
1. Internal battery fuse has opened (only if battery has been reverse polarity
connected), or
2. Battery circuit open - battery missing, or fuse / circuit breaker / wiring fault.
Either AC power has failed, or PSU has failed.
Battery system is OK
AC Power is off / DC has failed and battery has discharged to < V Battery Low, unit
will continue delivering battery current until low level initiates ELVD.
AC Power is off / DC has failed and ELVD has activated and disconnected battery
from load. Residual current drain on battery following ELVD <1 mA.
System is in STANDBY mode due to :
1. Operator pressed standby button, or
2. PSU has internal fault
PSU is in standby and battery has discharged to < Battery Low, unit will continue
delivering battery current until next level initiates ELVD.
PSU is in standby and ELVD has activated and disconnected battery from load.
Residual current drain on battery following ELVD < 1mA
Battery Condition Test is in progress: LEDs flash alternately
Battery Condition Unserviceable: failed to maintain terminal voltage during bat-
tery condition test
PSU is in standby mode and battery condition is determined as unserviceable:
failed to maintain terminal voltage during battery condition test
=Flashing Slowly
1. battery voltage drops below the Vdisco (1.66V/cell)
2. battery overcurrent or overload (refer to page 3)
Condition
=Off
