2. Synchronisation
In order to keep your battery monitor delivering accurate status information about your
battery, it is important to regularly synchronize your battery monitor with your battery. As
explained in the quick start guide, a synchronisation step is also needed before you can
actually use your battery monitor. During operation, the battery monitor automatically
indicates when a synchronisation is required, by displaying the message SYNCHRONIZE.
A synchronisation step means nothing more than performing a complete charge cycle on
your battery. A charge cycle will be considered complete when all discharged energy is
restored in the battery and both Auto-sync parameters F02 and F03 are met during at
least 4 minutes. This typically means : when the battery charger switches to float mode. By
meeting these conditions, the battery is considered full, which will be indicated by a
flashing FULL message on the display. Besides this, the State-of-charge readout will be
set to 100% and the Amphour readout reset to 0Ah. The FULL message will disappear
when a key is pressed, or automatically, when the battery starts discharging again.
Performing synchronisations regularly is also important to keep your battery healthy and to
increase it’s lifetime. You will notice that if you are often performing full charge cycles
yourselves, the battery monitor will most likely not display the SYNCHRONIZE message,
since the battery is already kept in good sync with the battery monitor.
Besides automatic synchronisations based on meeting the Auto-Sync Functions, you can
also manually synchronize the battery monitor with your battery when you are sure your
battery is fully charged. This can be accomplished by pressing both < and > keys
simultaneously for three seconds. After these three seconds, the flashing FULL message
appears on the the display just like when it is automatically synchronized.
Before proceeding with this owner’s manual, please make
sure you have carefully read the enclosed installation guide as
well!
3. Setup menu
Using the Setup menu, your battery monitor can be adjusted to fit into your system. A
number of parameters, called Functions, can be set according to your needs. This menu
can be accessed by the following sequence :
When the Setup menu is entered, you can use the < and > keys to browse through the
different Functions. By pressing the SETUP key, the selected Function value can be
viewed. The < and > keys can now be used to change this value. Pressing the SETUP key
again, will then step back to the Setup menu. From any menu position, the Normal
Operating Mode can be accessed again by pressing the SETUP key for 3 seconds. This
will also save any Function value changes to internal memory. When no keys are pressed
for 90 seconds while operating in the Setup menu, the battery monitor will automatically
return to the Normal Operating Mode again without saving any Function value changes.
The factory settings are based on a 12V battery system with a capacity of 200Ah. For 12V
systems, generally only Function F01 has to be checked for correct operation of your
battery monitor. When your battery capacity is other than 200Ah, Function F01 has to be
changed to a value that is equal to your battery capacity. All other Functions can be left
unchanged if you are uncertain about adjusting these values yourselves.
When your battery system is 24V, besides checking battery capacity Function F01 for the
correct value, you should also change the values of F02 and F05. Default 24V system
values for F02 and F05 are respectively 26.4V and 21.0V.
The following Functions are available :
F02
Charger's float voltage (
. This value must be equal to your
battery charger’s float voltage. which is the last stage of the charging process. In
this stage the battery is considered full.
Auto-sync parameter)
Default : 13.2V
Range : 8.0V - 33.0V
Step size : 0.1V
F03
Charger's float current (Auto-sync parameter). When the charge current is below
this percentage of the battery capacity (see Function F01), the battery will be
considered as fully charged. Make sure this Function value is always greater than
the minimum current at which the charger maintains the battery or stops charging.
Default : 2.0%
Range : 0.5 - 10.0%
Step size : 0.1%
F04
Low battery alarm On (% SOC). When the State-of-charge percentage has fallen
below this value, the alarm relay will be activated, the Charge battery indicator
starts flashing and the State-of-charge bar is empty.
Default : 50%
Range : 0 - 99%
Step size : 1%
F05
Low battery alarm On (Volts). When the battery voltage has fallen below this
value, the alarm relay will be activated.
Default : 10.5V
Range : 8.0 - 33.0V
Step size : 0.1V
F06
Low battery alarm Off (% SOC). When the State-of-charge percentage has risen
above this value and the alarm relay was activated, the alarm relay will deactivate
again. When “FULL” is selected, the alarm relay is deactivated when the Auto-
sync parameters are met.
Default : 80%
Range : 1 - 100% / FULL
Step size : 1%
F01
Battery capacity. Your Main battery’s capacity in Amphours (Ah).
Default : 200Ah
Range : 20 - 999Ah
Step size : 1Ah
F07
Peukert's exponent. The Peukert’s exponent represents the effect of reducing
battery capacity at higher discharge rates. When the Peukert value of your battery
is unknown, it is recommended to keep this value at 1.25. A value of 1.00 disables
the Peukert compensation and could be used for Lithium based batteries.
Default : 1.25
Range : 1.00 - 1.50
Step size : 0.01
F08
Shunt Amp Rating. This Function represents the Amp rating of your shunt at
50mV. 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.
Default : 500A
Range : 10 - 900A
Step size : variable
F09
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
F10
Alarm contact polarity. Enables selection between a normally open (NO) or
normally closed (NC) contact.
Default : NO
Range : NO / NC
F11
Auto-sync sensitivity. Only change this setting when F02 and F03 are set correctly
and automatic synchronization still
. If automatic
takes too
long or does
, lower this value. When the battery monitor synchronizes
too early, increase this value.

Default : 5
Range : 0 - 10
F12
Firmware version. Displays the firmware version of the battery monitor (read only).
Default : x.xx

Reset Battery status. Use this reset item to reset your current battery status, for
example after you have installed a fresh battery of the same specifications as the
previous one.
r.F
Reset Functions. This reset item can be used to reset all Function values to
factory default values.
The last two Functions are socalled Reset Functions. By pressing the SETUP key the
selected Reset Function can be viewed. The default value for all Reset Functions is “OFF”.
To actually reset the selected Function, use the < and > keys to change the value from
“OFF” to “ON”. Pressing the SETUP key again, will step back to the Setup menu. All reset
items set to “ON” will only be reset once the Normal Operating Mode is accessed again by
pressing the SETUP key for 3 seconds. The following Reset Functions are available :
