to the charging voltage.
If using lithium batteries, leave temp set to “NOR” (Normal) and leave temp sensor
disconnected.
Battery Temperature Compensation:
There are three manual battery temperature settings on the unit (‘Lo’, ‘nor’ and ‘hi’). See the
table below for voltage adjustments for temperature compensation.

Note: The above voltage compensation will only work with the supplied Battery Temperature Sensor tted which
will override the unit temperatures’ (Lo, Nor, Hi) setting. If using lithium batteries, leave temp setting “NOR“ (Normal)
and leave temp sensor disconnected.
Procedure To Set Or View Charger Setting

Procedure To Equalise Flooded Batteries
DANGER
Explosion Hazard And Risk Of Battery Damage.
The battery generates explosive gases during equalisation. Follow all the battery safety
precautions listed in the manual.
When using the equalisation mode, the user has to be sure the battery connected to
the battery charger is a ooded battery type. Equalizing a non-ooded battery may
overcharge the battery and may cause the battery to explode.
CAUTION
Risk of battery and equipment damage.
Only Flooded lead-acid can be equalised. Consult your battery manufacturer or read the
battery manual when you try to equalise your batteries.
Disconnect any DC load connected to the battery, as during equalise mode, the charger will
produce 31.0V to the batteries. You must monitor the battery specic gravity throughout
the equalisation process to determine the end of the equalising cycle.
Before setting the equalisation mode, please be sure the battery is a ooded battery type.
When the battery equalisation has started, the charger will automatically fully charge the
battery bank and will then follow with 1 hour of equalisation. Check the battery electrolyte
level during the equalisation period. If necessary, rell with distilled water only. All cells
should have similar electrolyte levels. If distilled water is added, batteries must undergo a
complete charge cycle. The charger cannot determine when to terminate the equalisation
of the battery, a one hour time-out is set and this is used as a safety feature to require the
user to continually re-activate it as necessary after checking batteries manually.
Use the following procedure to setup the charger for battery
equalisation.
With Flooded Battery Type setting, Press and Hold Button “SET“ and “SEL“ together for
more than 5 seconds. This will force the charger to go into to Equalized mode and it will
start equalizing the ooded battery. Please note the battery mode setting has to be set to
‘Flooded’ battery type in-order to have this function activated.
