CUSTOM BATTERY TYPE SETTING
(for expert
use only - not required for general operation)
Before proceeding with this, please read and
understand all instructions as it is quite complex and
could take more than one attempt. There are timed
intervals of 30 seconds per setting so it is very
important to know exactly what you require before
starting. If any errors are made simply wait a few
minutes and you can start the cycle again. The
settings offered for adjustment in sequence:
Important information:
If during these operations
you get yourself in a mess and find yourself pushing
buttons aimlessly, then please resort to the factory
reset. To delete all and return the product to its
default factory settings, refer to page 7 or 9 and start
again. Often, people simply switch the product off
during the button pushing frenzy.
A)
Boost / absorption voltage (high voltage charge).
B)
Conditioning voltage (medium charge rate
normally between boost and float voltage).
C)
Float voltage (no longer charging, this will provide
voltage at a reduced level to maintain the batteries
and provide power for any loads applied).
D)
Absorption time factor adjust. The length of time
spent in absorption can be adjusted by a factor 0-18.
This may be beneficial for different battery
chemistries. Gel, for example, tends to absorb
current at a low rate, thus, increasing the length of
time spent in absorption may be beneficial (set
nearer 18). AGM, the reverse (set nearer 0). If in any
doubt, ask your battery retailer or simply use one of
our preset values. To calculate the absorption time
from the time factor simply multiply the factor
number (0-18) by the length of time it takes for the
charging voltage to hit the absorption voltage
(typically 14.4V). If it takes 40 minutes to reach
absorption and you set your ATF to 4 then 4x40mins
= 160 minutes. The maximum time the unit can stay
in absorption is 24 hours 1440 minutes.
E)
Minimum and maximum absorption times.
Here you can set the maximum and minimum time
the unit stays in absorption. For example, you may
have AGM that may need a maximum of one hour,
or GEL which could require a minimum of 720
minutes (12 hours).
We recommend that you write down your required
voltages and times in the space below. This is so
you know what to programme during setup.

Operation
Press and hold both buttons for 10-20 seconds.
All Left LEDs shall flash
Press the setup/select button to move LED down to
custom. Hold both buttons for 2 seconds to confirm.

Red Custom LED
will flash for 3 seconds to confirm.
Red Custom LED
will come on constant,
Green Fast
Charge LED
will flash (section 1 on graph). Adjust
Fast Charge voltage by using the Select and Setup
buttons to go up and down the right LED column to
select the correct Fast Charge voltage. Once content,
wait 30 seconds, or press both buttons to confirm. The
unit shall then proceed to Conditioning charge voltage
(next below).
Opportunity to adjust Conditioning charge
voltage
Red Custom LED
will come on constant and
Green
Conditioning LED
will flash (section 3 on graph).
Likewise, adjust the conditioning voltage by using the
Select and Setup buttons to go up and down the right
LED column to select the correct Conditioning
voltage. Once content, wait 30 seconds, or press both
buttons to confirm. The unit shall then proceed to float
voltage set (next below).
Opportunity to adjust float charge voltage
Red Custom LED
will come on constant and
Blue
Float LED
will flash (section 3 on graph). Likewise,
adjust the float voltage by using the Select and Setup
buttons to go up and down the right LED column to
select the correct Float voltage. Once content, wait 30
seconds, or press both buttons to confirm. The unit
shall then proceed to float voltage set (next below).
Opportunity to adjust absorption time factor
Red High Temp LED
will come on constant.
Green
Fast Charge LED
will flash and
will
Blue Float LED
flash (section 1 and 4 on graph). This time, adjust the
time by using the Select and Setup buttons to go up
and down the right LED column (
refer to the
blue scale
scale 0-18
) to select the correct time. Once content,
wait 30 seconds, or press both buttons to confirm. The
unit shall then proceed to minimum absorption time
factor (next below).
Why use Absorption Time Factor (ATF)?
ATF is simply a number (0-18) that can be used to
multiply by the length of time the charger takes to
reach the bulk/boost voltage from start. For example,
if the bulk voltage is reached in 10 minutes with the
ATF at 4, then 10mins x (ATF 4) = 40 mins of
absorption.
