Programming the system
Procedure
1. Showing software version (automatically).
2. Battery type configuration (manually)
3. Battery capacity configuration (manually)
4. Configuration of charge level (manually)*.
5. Saving the selection (automatically).
6. Check for relay (automatically).
7. Indication if relay was found or not (automatically).
8. Change to Standby mode
configuration of system is complete (automatically).
* For easy charge level selection it is most practical to leave the yellow (Prog/Link) wire open and finish
first the configuration (contacting to GND) and only connect to Link Push-Button or green wire of battery
monitor when DBM20A has switched to Stand-By mode (DBM Status LED is flashing green).
The System automatically starts up when the black (GND) and the red (+Main) wires are connected and
first shows its software version. After that all the LED’s are flashing for 30s, in this time it can be
switched in the configuration mode when the yellow (
Prog/Link)
wire is briefly contacted to GND.
If no change is made in one of the three configuration steps, the system automatically switches to the
next configuration step after 15 seconds with the corresponding LED flashes quickly. After a change,
the system changes to the next configuration step after only 5 seconds of inactivity. If the configuration
mode is not started, the DBM20A starts with a fast flashing pattern, in the default mode (Low
Level/Lead-Battery/80-150Ah) or the last saved configuration.
The fallowing settings can be made in the configuration mode.
Configuration Li-board battery (LiFePO4,)
If the Main Battery LED lights up green, the DBM is in the battery type
configuration. With a short ground contact of the Link/Prog wire, you can
switch back and forth between lead and Li batteries. If the DBM status
LED flashes green and red, the DBM is in the Li-battery configuration. If
the LED only flashes green, the DBM is configured for lead batteries
(default). The 2 types of batteries repeat in a cycle.
Status LED
Battery type
Lead-battery
Lithium-battery
Configuration Battery capacity
If the Charge Status LED is green, the DBM is in the battery
capacity configuration. With a short ground contact of the
Link/Prog wire, you can switch between the three different sizes.
The 3 capacities repeat in a cycle.
High Level
Batteries > 150Ah
Medium Level
Batteries 80-150Ah
Low Level
Batteries < 80Ah
