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 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, Fault Code
E03 on display will appear. In some cases, the user replaceable DC fuse
located near the DC Output terminals may blow and Error code E08 will
display.
AC Input Voltage Protection:
The charger will shutdown when it senses the AC input voltage is outside
of the operating range. A fault code will display ‘E02’. The charger will
recover automatically when it senses the AC input voltage has returned
back to the normal operation range.
Charging A Dead Battery
The charger is designed to charge batteries with terminal voltage
greater than 2.5Vdc.
Re-charging a dead flat 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.
