Link error (Relay error)
Error occurs the latest after 5 minutes when relay is
defective or removed. The DBM20A operates now as
if there was no relay. Check connections to relay.
Check the relay. When new relay is installed start the
engine and press the link push-button (LSK)
respectively the link button (DBS) to start a relay
check.

What to do / Resetting
Errors 1-5 are reset automatically when conditions are normal again.
Errors 6-9 (indicated without the green LED flashing) are reset automatically after 30 seconds.
24V/12V:
Over voltage alert error 3, blue (+Aux) wire was first connected -> connect first the red
(+Main) wire.
Alarm in combination with IBS-DBS (up to Software 8.0)
The combination of the DBM20A with a IBS-DBS and IBS-Relay can lead to an over voltage alarm*.
Because of higher charge voltage of the DBM20A compared to alternator charge voltage it is also
possible to have a Link failure alarm* with IBS-DBS due to the difference between the Main and the Aux
battery voltages of more than 0,5V.
* These alarm is indicated on IBS-DBS.
