DESCRIPTION
is right for the batteries used.
Disconnect all the voltage sources (B71/PBX will switch off) then connect
again, starting with the battery.
Battery voltage too high detected
Battery voltage too low detected.
Current supplied by batteries too high. In this situation B71/PBX disconnects
the power supply to the control unit (self-protection), and after a few seconds
returns to power supply. This happens for example if you have B71/PBX
connected to the central unit, and you connect the batteries to B71/PBX to
perform the test: you have a peak of current absorption and therefore you will
see the display of the central unit turn on, turn off and after a few seconds turn
on again.
Short-circuit detected in the battery charger section
Fault detected in the battery charger section
OFFSET error. Error in the calibration of the battery current measurement
circuit.
NOTE: the OFFSET alarm is critical and inhibits the automatic reset of the
battery charger functions. Contact Customer Service.
Incorrect calibration of the battery voltage measurement
