Battery Separator
1314-200, 1315-200 and the 100 amp version 1314 & 1315 is designed for use in multi-battery applications as a solenoid priority system to protect the chassis charging system from excessive loading while allowing auxiliary batteries to be charged. The BATTERY SEPARATOR has two basic operational characteristics:

Assist In Engine Starting
When the starter is activated the BATTERY SEPARATOR compares the voltage of both battery banks. IF the chassis' battery is lower than the auxiliary battery bank, the BATTERY SEPARATOR will engage allowing the auxiliary battery bank to aid in vehicle starting. The start signal must be at least three volts for the operation to occur.

Protect The Charging System
The BATTERY SEPARATOR monitors the battery system to determine if the batteries are being charged. When the engine or auxiliary batteries (if 1315 is used), or the engine batteries (if 1314 is used) reach 13- 13.5 volts, indicating charging is taking place, the BATTERY SEPARATOR will engage, joining the two battery banks. If the drain on the charging system by the auxiliary or main battery bank reduces the system voltage below 12.4-12.9 volts, the BATTERY SEPARATOR will disconnect the battery banks from each other, thus protecting the respective battery banks from excessive drain. A delay function has been incorporated in the control circuit to prevent the BATTERY SEPARATOR from reacting to momentary voltage fluctuations and chattering.

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.

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 12.8V, 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.

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.
