OVERVIEW
The 1318 and 1319 are 100A battery separator modules with an integrated relay for 28V systems—the 1318 is
unidirectional and the 1319 is bidirectional. The 1318 monitors only the main battery and charges the auxiliary
battery if the main battery is above the connect threshold. The 1319 monitors both the main and auxiliary battery
banks. If either battery bank is above the connect threshold, the relay connects the two banks together. If the
batteries are below the disconnect threshold, the unit will open the relay. The connect threshold is set to a
nominal voltage of 26.8V, which would only be reached when the charging system is operational. This will cause
the relay to only close when the charging system is operational, charging both banks of batteries. The disconnect
voltage is set to a nominal 25.7V, 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.
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 bank. 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 bank. 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.
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 (Main – 0.85V).
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.

2.2V is the typical voltage drop from Main
Battery to the Start Lamp output (Battery
voltage being the higher of the two battery
voltages).
V
Nominal minimum voltage required on START
SIGNAL input for the input to activate.
S
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.
S
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.
