Description
 
The 1314 (unidirectional) and 1315 (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 1314) or either battery bank (for the 1315) is above the connect threshold, the relay connects the two banks together. If the main battery (for the 1314) or either batteries (for the 1315) 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 1315 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.
