The 1314-200 (unidirectional) and 1315-200 (bidirectional) are 200A 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 1314-200) or either battery bank (for the 1315-200) is above the connect threshold, the relay connects the two banks together. If the main battery (for the 1314-200) or either batteries (for the 1315-200) 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 12.8V, 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.

Note: For the 1315-200 model, the battery connections can be reversed.

Battery Separator Installation

1. Mount the Battery Separator in a convenient location near the main battery bank. Do not mount in direct engine
heat. Drill 7/32 holes for -20 self-threading screws and lock washer. For material less than 0.10 add a washer
and nut (not included).
2. Connect one end of a new wire of the proper size (see wire size chart) to the main battery terminal of the Battery
Separator.
3. Connect the opposite end of a wire installed in step #2 to the main battery positive (+) terminal.
4. Connect one end of wire of proper size (see wire size chart) to the auxiliary battery terminal of the Battery
Separator.
5. Connect the opposite end of the wire installed in step #4 to the auxiliary battery positive (+) terminal.
6. Make sure the auxiliary battery is properly grounded to the vehicle chassis.
7. Ground Connection. Connect a #14 gauge wire between chassis ground and the Battery Separator ground
terminal. This may momentarily activate the Battery Separator. This is normal.
8. Auxiliary Start Connection (optional). Automatic operation. Connect a #14 gauge wire from the start position of
the ignition switch to the Start terminal of the Battery Separator. Make this connection at the ignition switch. This
wire should only have voltage when the ignition switch is in the start position. Note: The start signal must be able
to produce at least 3V* in order to provide automatic boost, see connection diagram above for manual operation
option.
9. Lamp Connections (optional). Connect a #14 gauge wire from the Lamp terminal of the Battery Separator to one
end of an indicator lamp (250mA maximum current draw). Connect the opposite end of the lamp to the chassis
ground. This lamp will illuminate when the auxiliary start function is activated.
10. Checking the Operation: The Battery Separator should now be operational. Start the vehicle or apply a charge
to the main battery. Once the main battery rises to 13.2V* the Battery Separator should activate. Turn off the
vehicle or remove the charge to the main battery. The Battery Separator should disconnect the auxiliary battery
once the voltage on the main battery drops below 12.8V*.
11. If a model 1315-200 is used, apply a charge to the auxiliary battery. When auxiliary voltage rises above 13.2V*,
the Battery Separator should activate. Remove charging unit, the Battery Separator should open when auxiliary
battery is less than 12.8V*.
12. The auxiliary start function should activate the Battery Separator if the main battery voltage is lower than the
auxiliary battery. The start terminal must see at least 3V* to activate. The auxiliary battery must read at least
10V*.

5 of 5 Purchasing 1315-200 Battery Separator October 4, 2019
Reviewer: Rick Leary from Shoreline, WA United States  
Using a digital voltmeter and the electrical schematic for the RV, I decided to check the voltage on the batteries and on each side of the Battery Separator.  The car battery read 12.84 V with the engine off and the house battery read 12.45 V.  With the engine on the voltage now read 13.4 V ( car side) and 12.43 V (house side).  There was a problem with the separator since 12.84 is above the lower limit for the separator and both side should read 13.4 V.  Supplying shore power itt read 14.2 V on the house side  and 12.8 on the car side.  It should read 14.2 on both side since for the same reason cited above.
I did an internet search and found the ASE-Supply website and quickly found the 1315-200 battery separator.  I placed the order and had it shipped UPS ground.  It came the next day.  I replaced the separator.  Did the same tests.  13.4 and 13.4 V with the engine running.  14.2 and 14.2 V with shore power.  Problem solved.  Now I am a happy camper.
