OVERVIEW
The 1314A (unidirectional) and 1315A (bidirectional) are 100A battery separator modules with an integrated relay
for 12V systems. The units monitor both the main and auxiliary battery banks. If the main battery (for the 1314A)
or either battery bank (for the 1315A) is above the connect threshold, the relay connects the two banks together.
If the main battery (for the 1314A) or either batteries (for the 1315A) are below the disconnect threshold the unit
will open the relay. The connect threshold is set to a nominal voltage of 13.2V, which would only be reached when
the charging system is operating. This will cause the relay to close and the charging system can charge both
banks of batteries. The disconnect voltage is set to a nominal 12.7V, which is near the full charge resting voltage
of the batteries. This will cause the relay to be opened shortly after the engine is stopped, attempting to preserve
100% of the starting battery capacity for engine cranking. An optional start override is also available. When the
engine is started, the start signal causes the controller to check if the auxiliary battery is within about 1V of the
main battery; if so, the relay contact is closed; thus, providing the starter system with maximum battery voltage
available.
UNIT CONNECTIONS
The unit has five connections (see Connection Diagram for locations):
1.
Main Battery connection
This is the high current connection to the main battery. This connection is made directly to the relay. Product
labeling refers to this as the MAIN BAT connection. The unit is powered from the main battery connection or
the auxiliary battery connection, drawing power from whichever has the higher voltage.
2.
Auxiliary Battery connection
This is the high current connection to the auxiliary battery. Product labeling refers to this as the AUX BAT
connection. The unit is powered from the main battery connection or the auxiliary battery connection, drawing
power from whichever has the higher voltage.
Note: For the 1315A model, the battery connections can be reversed.
3.
Ground
This is the unit ground connection.
4.
Start Signal input
This is the input for engine start signal override. When power is applied to this input, the relay will close if the
Aux. Battery is no less than 0.85 Volts below the Main battery.
5.
Start Lamp output
This is the start lamp drive output. The start lamp is powered when the start signal input has caused the relay
to close. This output can source up to 250mA to an incandescent lamp. For LED type indicator, see
MAXIMUM RATINGS, START LAMP drive current.

When the battery voltage rises above the
connect voltage and the relay closes, this is
the minimum amount of time it will stay
closed, regardless of the battery voltages.

When the battery voltage falls below the
disconnect voltage and the relay opens, this is
the minimum amount of time it will stay open,
regardless of the battery voltages.
