Procedure to Equalize Flooded Battery:
DANGER
: Explosion Hazard. The battery generates explosive gases during equalization.
Follow all the battery safety precautions listed in the manual.
DANGER
: Explosion Hazard and Risk of Battery damage. When using the equalization mode,
the user has to be sure the battery connected to the channel is a flooded battery type.
Equalizing a non-flooded battery may overcharge the battery and may cause the battery to
explode.
CAUTION
: Risk of Battery and Equipment damage. Only the Flooded lead-acid can be
equalized. Consult your battery manufacturer or read the battery manual when you try to
equalize your batteries. Disconnect any DC load connected to the battery, as during
equalize mode, the charger will produce 16V on 12V model, or 32V on 24V model to the
batteries. You must monitor the battery specific gravity throughout the equalization process
to determine the end of the equalizing cycle.
Before setting the equalization mode on the specific channel, please be sure the channel
chosen for battery equalization is for a flooded battery type. When the battery equalization is
started, the charger will automatically fully charge the selected channel first and follow with 1 hr
of equalization. Check the battery electrolyte level during the equalization period. If necessary,
refill 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 equalization 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.
During equalization mode the other two banks are disabled.
Use the following procedure to setup the charger for battery equalization.
Understanding the Silent Mode Function
The charger also comes with another unique ‘Silent’ Mode function that will stop the internal fan
operation.
Tips: Use this function during night time or when a quiet environment is needed. Please also
note that the charging time will increase in this mode because the charger is not running
at maximum power.
This function can switch to ON or OFF at any time during the charging period.
To set this function, press and hold ‘SET’ key for 3 seconds to execute the ‘Silent’ Mode. The
‘Auto’ icon will show on the display.
To turn this function off, press and hold the ‘SET’ function for 3 seconds to turn off ‘Silent’ Mode.
The ‘Auto’ icon on the display will turn off and the charger current and the fan speed will return
to normal.
The charger will also automatically deport Silent Mode after 12 hours from initial depress.
Understanding the Protection Features
De-rating Charging Current:
When the charger senses the environmental temperature is above 50°C, the maximum
charger current will de-rate to 1/2 of the value (A02 warning code will display). The charger
