During this particular setup procedure we have made
the voltage setup LED bar more sensitive so that the
adjustment can be made in 0.1V increments. For
example, for 13.1V the 13V LED is on and the 13.4V
LED is flashing. The same idea for 12.9V. The 13V
LED is on and the 12.6V LED is flashing.

Setting Menu. At the same time the actual
Cutoff
voltage
will be displayed in the left LED voltage bar
according to the description above. To decrease
voltage press SETUP/ENTER and to increase
voltage press SELECT button.
The
range you can choose is
Cutoff voltage
between 12.0V-14.6V.
Charging voltage is always 0.2V higher.
Lower voltage trip is always 1.1V lower.
Low voltage trip (ignition mode) is always 3.0V
lower.
If you do not touch any buttons for 30 seconds the
default voltage of 13.0V shall be restored and saved.
To confirm your custom voltage you must press
both buttons (SETUP/ENTER) and (SELECT)
simultanously for 2 flashes.
The chosen voltage will be saved and the unit will
restart. If you feel unsure, do not touch any buttons.
The default value will be restored automatically.

Adjustment of operational voltages.
The 4 main control voltages below are inextricably linked.
The voltages can only be adjusted as a block (not
individually). For example, if you wish to reduce the
Cutoff
voltage
by 0.2V then all other voltages in the block shall
reduce by 0.2V.

regen braking timer
All 4 voltages are always
linked. This block can be
adjusted by changing the
Cutoff voltage
value up and
down. This subsequently
changes the other three
voltages by the same value.
Charging voltage (default 13.5V) (always 0.3V above
Cutoff voltage)
:
At this voltage the charger starts
charging. After 5 seconds above 13.2V the regen braking
timer is set. If the input voltage drops to 11.9V - 13.0V this
timer begins. Timer reset when input voltage is 13.2V+.
Cutoff voltage (default 13.2V):
This voltage is only
relevant after the
charging voltage
has been met and the
charger is charging. When the input voltage drops below
this cutoff voltage the charger stops charging and shall
eventually go to sleep. If the input voltage remains
between 13.2V-13.5V the charger shall continue charging.
The
Cutoff voltage is the parameter that the user
changes.
Cutoff voltage
As noted, by adjusting the
you
change the other three voltages mentioned by the same
amount.
Lower voltage trip (default 12.0V) (always 1.2V below
Cutoff voltage)
:
When the input voltage drops below the
Lower voltage trip
the charger turns off. The 11.9V
threshold is only relevant if the
is
regen braking timer
activated. If not, then the low voltage trip is 13.0V. If in
ignition feed mode, the low voltage trip is 10.0V.

FINAL custom setting.
The final setting to adjust in the custom
configuration is to set temperature trip. This turns off
the BB’s charging if this temperature is reached at
the temp sensor (
if temp sensor not fitted, then
this mode is irrelevant
). The default, as it assumes
lead acid, is -30 Deg C, so the RED LED at the
bottom shall illuminate (24). For lithium, bring this
LED up to your desired trip temperature. E.g 0, -2, -4
Deg C etc. Use the SETUP and SELECT button to
bring the LEDs up and down the second column to
the desired temperature. Press both buttons to
confirm the selection. If you have lead acid
batteries. We recommend leaving it at -30DegC
(default) - if charging lead acids. Lithium batteries
may vary around the 0DegC mark.
