3.0 Adjusting the ME-SBC
TM
The above diagram represents a typical three-stage charging profile. The first of the
three stages is Bulk Charge. This is where up to 80% of the charging is accomplished.
During this stage the battery voltage increases significantly and the current that
the charging source is providing to the Main Battery is at a maximum. The second
stage is Absorption, during this stage the battery voltage is held at the Absorption
voltage for a period of time. By the end of this process the charge on the battery
bank is about 95% complete. The third and final stage is Float. In this stage, the
remainder of the charging is accomplished. As long as the Main Battery voltage is
between the Low Voltage Disconnect and the High Voltage Disconnect, and
the Main battery voltage is above the Connect Voltage, the ME-SBC
TM
will pass
charging current through to the Auxiliary Battery.
The ME-SBC
TM
combining setpoints as follows:
Connect Voltage: (Settable: 12.8-13.8 VDC) adjusts the point at which the ME-SBC
TM
passes the charge from the Main Battery bank to the Auxiliary Battery bank or vice
versa. This setting is not active until a charging source is applied to one of the batteries
and the voltage begins to increase. Once this setpoint has been reached, the ME-SBC
TM
will
automatically start to pass the charge current through to the other battery. Default = 12.8 /
25.6 VDC (12V /24 V system)
Low Voltage Disconnect: (Settable: 12.5-13.5 VDC) once the charging process has begun
and the battery voltage has exceeded the Connect Voltage setpoint, the Low Voltage
Disconnect becomes active. If the voltage begins to decrease, this is the point at which the
ME-SBC
TM
disconnects and stops passing charge current through to the other battery. Default
= 12.5 / 25.0 VDC (12V /24 V system)
High Voltage Disconnect: (Settable: 14.0-15.0 VDC) This setting should be used to
prevent the ME-SBC
TM
from passing through too high of a voltage from one battery to other.
If this voltage is reached, the ME-SBC
TM
disconnects the batteries and prevents the high volt-
age from affecting the other battery. Default = 14.0 / 28.0 VDC (12V /24 V system)
