Alternator types
Important settings
In order for the smart alternator detection to work reliably, the IGN connection (light blue) must be
connected to the ignition or Terminal 15. This connection can be left open on vehicles with a classic
alternator.
With the battery size selection (new programming step 2, selection: small (<80Ah), mid (80-150Ah),
large (> 150Ah)), the system knows how big the additional battery is and optimizes the relay time
accordingly.
Li-ion auxiliary batteries are increasingly being used. Here it is important to correctly configure the
DBM20A for lithium (new programming step 1) so that all switching points and control parameters are
adjusted and the equalize mode is deactivated.
If an IBS-DBS is also installed on the DBM20A, it is very important that the correct programming of the
DIP switch settings (see page 8 in the IBS-DBS manual) is carried out, especially the lithium and
DBM20A configuration.
With DBM20A installations without LinkStartKit or IBS-DBS, older versions can also be used in vehicles
with Smart Alternator.
