Notes:

1. When the battery type is sealed, gel, flooded, the adjusting range of equalize duration is 0 to180min and boost duration is 10 to180min.

2. The following rules must be observed when modify the parameters value in user battery type (factory default value is the same as sealed type): a) Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize

Charging Voltage ≥ Boost Charging Voltage ≥ Float Charging Voltage >

Boost Reconnect Charging Voltage. b) Over Voltage Disconnect Voltage > Over Voltage Reconnect Voltage c) Low Voltage Reconnect Voltage > Low Voltage Disconnect Voltage ≥

Discharging Limit Voltage. d) Under Voltage Warning Reconnect Voltage > Under Voltage Warning

Voltage ≥ Discharging Limit Voltage. e) Boost Reconnect Charging voltage > Low Voltage Disconnect Voltage.

NOTE: Please refer to user guide or contact with the sales for the detail of setting operation.
