Alarms for ChargeMaster battery chargers

The ChargeMaster 12/35-3, 12/50-3,

24/20-3 and 24/30-3 are equipped

with simple alarms using LEDs on

the front panels.

Above models are protected against

overload, short circuit, over heating

and under and over voltage. If a fault

condition occurs, a load bar segment

on the display illuminates red. The LED

position indicates the failure cause.

* The

POWER

button is blinking.

** At ‘

Battery low

’ the battery

bank number concerned is

blinking. Selecting another

bank is still possible then,

the display will return after

5 seconds.

The larger models such as the

ChargeMaster 12/70-3, 12/100-

on the display. The origin of the error is

displayed by means of an error code.
