F6.1
Shunt Amp Rating. This Function is linked to F6.2 and represents the Amp rating
of your shunt at the given voltage indicated by F6.2. Included with your battery
monitor is a 500Amp/50mV shunt, meaning that at 500A flowing through the
shunt, a voltage of 50mV is generated across the small ‘Kelvin’ screw terminals of
the shunt. This voltage will be used by the battery monitor to measure the amount
of current.

the given current indicated by F6.1. The battery monitor supports 50mV and 60mV
shunts.
Default : 50mV
Range : 50 / 60mV
F6.3
Backlight mode. Represents the duration of backlight activation in seconds after
key-press. The backlight can also be set to be always “ON” or always “OFF”.
Function setting “AU”, activates the backlight automatically when charge /
discharge current exceeds 1Amp or when a key is pressed.
Default : 30sec
Range : OFF / 5…300 / ON / AU
Step size : variable
F6.4

normally closed (NC) contact.
Default : NO
Range : NO / NC
F6.5
Voltage prescaler. This Function is only important when an optional voltage
prescaler is installed on the battery monitor. All voltage related Functions are
linked to this Function F6.5. Always keep this Function set to “1-1” when no
prescaler is installed!

A
input terminal on
the rearside of the battery monitor, and can be set in two modes. In mode “0”, the
V
A
input operates in normal voltage measurement mode. In mode “1”, the V
A
input can be used to control the backlight. In this mode, the backlight is switched
ON at an input voltage higher than 2V and switched OFF again if the voltage is
below 1V.
Default : 0
Range : 0 / 1
F6.8
Communication mode. This Function is used to configure the data output mode.
There are four data output modes :
Mode “0”
: SBM-02 (broadcasting)
Mode “1”
: SBM-02 (request mode)
Mode “2”
: SBM-01 compatibility mode (broadcasting)
Mode “3”
: SBM-01 compatibility mode (request only)
Default : 0
Range : 0 / 1 / 2 / 3
F6.9
Setup lock. When set to “ON”, all functions (except this one) are locked and
cannot be altered. The Reset menu is also locked.
Default : OFF
Range : OFF / ON
In the Reset menu, you can reset a number of items of your battery monitor This menu
can be accessed by the following sequence :
6. Reset menu
When the Reset menu is entered, you can use the < and > keys to browse through the
different reset items. By pressing the MENU key, the selected reset item can be viewed.
The default value for all reset items is “OFF”. To actually reset the selected item, use the <
and > keys to change the value from “OFF” to “ON”. Pressing the MENU key again, will
step back to the Reset menu. All reset items set to “ON” will only be reset once the Normal
Operating Mode is accessed again by pressing the MENU key for 3 seconds. The
following Reset menu items are available :
rSt.a
Reset alarms. Use this reset item to reset or ignore all current alarms.
rSt.b
Reset Battery status. Use this reset item to reset your current battery status (CEF,
State-of-charge and battery history). You can use this reset item after you have
installed a fresh battery of the same specifications as the previous one.
rSt.F
Reset Functions. This reset item can be used to reset all Function values to
factory default values.

7. Troubleshooting guideline
The monitor doesn't operate (no display)
- Check monitor- and battery side
connections.
- Make sure the inline fuses are installed
and not blown.
- Check battery voltage. Battery might be
flat. Vbatt must be >8VDC.
- Try to restart the monitor by removing /
placing the fuses again.
- Current sense leads from the shunt are
reversed. Check the installation guide.
Problem
Remedy or suggestion
Current readout gives wrong polarity
(positive current instead of negative when
discharging)
The monitor resets all the time
- Check the wiring for corrosion and / or
loose contacts.
- Battery might be flat or defective.
No changes can be made in the Function
setup
- Check if the setup-lock is OFF (Function
F6.9)
- Your SBM-02 might be locked by the
superlock. Ask the installer for the
password to unlock the monitor using the
PC-link.
“CHARGE” or “SYNCHRONIZE” keeps on
flashing
- Charge battery full (synchronize your
battery with the monitor)
- Check the Auto-sync parameters in
Functions F1.0, F1.1 and F1.2 for possible
wrong settings.
State-of-charge and/or time-to-go readout
not accurate
- Check if all current is flowing through the
shunt (the negative terminal of the battery
may only contain the wire going to the
battery-side of the shunt!).
- Current sense leads from the shunt are
reversed.
- Check all Battery properties Functions (F5)
- Check if battery monitor is synchronized.
Display returns '- - - -' in temperature
readout
- Connection with temperature sensor is lost.
Check for failed connections and/or cable
damage.
Battery voltage readout is highly inaccurate
- Check prescaler setting in Function F6.5
