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 set value (A01 warning code will display). The charger

will recover automatically back to maximum charging current when the environmental

temperature drops to below 45°C.

Over Temperature Shutdown:

When the charger senses the environmental temperature is above 60°C, the charger will

shutdown. It will recover automatically when the environmental temperature drops to

below 45°C.

Battery Reverse Polarity:

When a reverse polarity is connected to the battery bank, “Error Code E08” on the display

will appear.

Charging A Flat Battery

The charger is designed to charge batteries with terminal voltage greater than 8.0Vdc.

Re-charging a at battery requires extreme care and attention. It is best to re-charge using

short frequent cycles rather than one long bulk cycle. Battery damage or failure may occur

if the battery is discharged so deeply.

Understanding The Display Codes

Codes will show on the display when either a function or internal warning / fault, such as

high internal temperature or DC out of range is detected and the charger may shut down to

protect itself until the fault has cleared. See table description below for more information.

Code Description

The charger is in Bulk Charging Mode

Bulk or Boost charge; The battery is charged at the set rated output current of the charger until the battery reaches its nal

charging voltage, known as its absorption voltage. In this step, around 80% of the battery is recovered as fast as possible.

The Charger is in Absorption Charging Mode

Absorption Charge; With the charger voltage held steady, the remaining 20% is replaced with the charger allowing

the current to taper o as the battery approaches full charge.

The charger is in Float Charging & Power Supply Mode

Float; Finally, in the oat stage the charger voltage is lowered and held at a constant and safe predetermined level.

This prevents the battery from being overcharged, yet allows the charger to supply enough current to make up for the

self-discharge losses of the battery, while supporting additional loads connected to the battery (such as DC lighting and

refrigerators). This stage allows for the charger to be used as a DC power supply.

CH3 Input Voltage Check

This will display for 5 seconds every 3 minutes while charging from the alternator input (CH3) and is normal operation

when the charger is checking the under voltage recovery limit (see page 18 for details).
