IBS-DBS Functions

Display of Battery Voltage (Energy Level) 

LED indicators:

  • green: Batteries are in the safe working range
  • yellow: check batteries
  • red: Batteries should be charged

The LED’s show the energy level if all loads are switched off:
 12.6V = 100%
 12.4V = 75%
 12.2V = 50%
 12.0V = 25%
 11.0V = flashing and beeping indicates low battery situation

This function is called by pressing the display button for about 30 seconds.

Display of Charge Voltage while charging

LED indicators: 

  • red:     >14.5V: High loading of Batteries, may be present at cold ambient temperature for a longer time.
  • yellow: >14.0V: Proper charge mode.
  • green:  <14.0V: Save charge mode, no damage to batteries.

New bi-directional Automatic Battery link

While the engine is running the Main and Aux batteries are linked together for parallel charging from the alternator (green LED linked is on). If the engine is stopped, the two batteries will be disconnected automatically with some delay. Appliances as fridges, lights, compressors, inverters are now safely fed from the Aux battery. With the additional charge by solar equipment, battery charger or generator is sufficient for charging, the starter battery will be charged automatically with Aux battery together (green LED "link" lights). 

Manual Battery "link"

In an emergency situation (defective or empty Main Battery) or in case of higher power consumption the two batteries (Main & Aux) may be connected together by activating the link button (red LED manually linked is on) After a laps of time of 30 minutes (or immediately after activating the auto button), the system returns to the automatic mode. When using an electric winch, the battery connection can be activated for 180 minutes by pressing twice the link button. In this mode sounds every 30 seconds a Beep to remind this status(Auto return after time expired). The load sharing function with the manual battery connection reduces the load on the alternator, the wiring and the batteries in the use of the winch.

Alarm functions:

Low Battery alarm: If the battery voltage of one or both of the batteries, is for a longer period below 12V, the sound Low Battery with "Beep" and the LED "Low Battery" of the corresponding battery (Main and / or Aux) flashes. With the Display button, the "Beep" is switched off. The blinking LED "Low Battery" is reset if the battery voltage is exceeding 12V.

Link failure alarm: The monitor monitors the charge on both batteries. When fitting charge ( from alternator, solar, charger) no charge to the other battery is detected, the link error alarm with flashing green LED "linked" and the “Beep” sounds. If this error occurs, check immediately the wiring of the power cables to (relay, battery terminals, crimp contacts, control relays). After bug fixes, the alarm will automatically reset.

Deactivation of automatic and manual battery dual link function:

Is there a problem with the auxiliary battery (Aux) as short circuit of cells, short circuit or defective battery housing, leading to damage of the generator (alternator). In an emergency situation the battery system can be operated in the vehicle in the basic configuration (alternator, starter battery without additional charge to battery aux). By pressing the link button for 6 seconds (until the sound of the beep), the link is deactivated. In this mode, no manual and automatic battery connection is possible. This feature can after solving the battery problem of the battery Aux by pressing the Auto button for 6 seconds to be reset. Now the system is working again with all the functions.
