4) Initial Operation / Handling
After the DBL is attached to the mains supply, the internal functions of the device are checked immediately. If the battery
charger is technical alright, the integrated microcontroller switches to ready for operation and the DBL is now ready to
start the charging process immediately - this is signalled via the blinking of the yellow LED [4].
Battery Charge Mode - Operation State / Functions:
If the clamps on the output of the DBL are connected to a technical irreproachable lead
acid-/AGM-/VRLA battery then this is recognized from the internal load detection circuit of the DBL. The charging process
can be started after the security functions of the DBL are executed and the accumulator among other things is checked
on deep discharge and reverse polarity.
LED 1 (red), ON

B
attery connected with reverse polarity
LED 1 (red), blinking
-
Internal device error
LED 2 (green), ON
- Charging process finished
- The micro-controller circuit of the DBL is permanently checking the state of
the connected accumulator and controls the switching to trickle charge mode
(in this operation mode the charging voltage is reduced to a safe value).
LED 3 (yellow), ON
- The connected lead battery is ’half full’ (charging process is continued)
- The current consumption of the battery is declining
(charging process with voltage ’U
0
’)
LED 4 (yellow), ON
- The connected battery was detected and the internal security check
concerning proper connection, reverse polarity, deep discharge etc.
has been finished
- The lead battery is empty ('discharged')
-
Charging process is working with ’I
-
const’ at the output current threshold
LED 4 (yellow), blinking
- Ready to charge a battery (as soon as a battery is connected the
charging process is ready to start)
- Internal security check of the DBL has detected a defective battery
(e.g. deep discharged battery)
Standby Battery Charge Mode - Operation State / Functions:
By pressing the DBL's START/ STOP push-button the operation mode is changing from 'Charge Mode' to 'Standby
Battery Charge Mode', which is signalled with a synchronous blinking of the three operation LEDs (1x green / 2x yellow).
LED 2/3/4 (green / 2x yellow),
blinking synchronous
- The DBL charging computer has been stopped and is now
in operation state 'Standby Battery
Charge Mode'
