The 1318-200 (unidirectional) and 1319-200 (bidirectional) are 200A battery separator modules with an integrated
relay for 24V systems. The units monitor both the main and auxiliary battery banks. If the main battery (for the
1318-200) or either battery bank (for the 1319-200) is above the connect threshold, the relay connects the two
banks together. If the main battery (for the 1318-200) or either batteries (for the 1319-200) 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 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 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. When the engine is
started, the start signal causes the controller to check if the auxiliary battery is within about 0.85V 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:
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.
Note: For the 1319-200 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
