ADJUSTING THE VOLTAGE SET-POINTS
The operating voltage set-points can be changed via adjustment screws accessible from the
front. On both BATTERY SAVER Models 1 and 6, two pots are provided for adjustment, one
for the LVD (or generator start) set-point and one for the SPAN or voltage change before a
reset.
Equipment required: Variable power supply with meter, small adjustment screwdriver.
1) Disconnect BATTERY SAVER from system.
2) Connect the power supply plus and minus to the terminals marked "Batt+" and "Batt-"
respectively.
3) Vary the power supply voltage in the area where the LVD (or GENERATOR START) is set,
observing when the LED light goes on and off.
4) Subtract the value of the desired LVD (or GENERATOR START) voltage from the desired
stop voltage. This becomes the "SPAN" value.
5) Set the desired span via adjustment of the "SPAN ADJ." adjustment screw. Turning the
screw clockwise increases the span, counter-clockwise decreases it.
6) Vary the power supply voltage once again to determine the new span value.
7) Repeat steps 5 and 6 until the desired span is achieved. The LVD (GENERATOR START)
value will not be correct.
8) Turn the LVD (START ADJ.) adjustment screw clockwise to decrease the set-point, and
counter clockwise to increase it.
9) Vary the power supply voltage to determine the new start value.
10) Repeat steps 8 and 98 until the desired set-point is achieved, repeat step 3 to verify the
accuracy of the new set-points.
OPERATION
Once the BATTERY SAVER is installed, the operation is automatic, and specific to each
model.
BATTERY SAVER 1 (BS1) - Low-voltage load disconnect -
When battery voltage reaches the low-voltage threshold, the normally closed relay will
energize and open. The red Light Emitting Diode (L.E.D.) on the front panel will light and
the load will be disconnect. When battery voltage rises, indicating charging has occurred,
the load will be automatically reconnected.
BATTERY SAVER 6 (BS6) - Generator Start -
For systems designed with stand-by generator backup, the BATTERY SAVER can signal
when low batteries need additional charging. When battery voltage reaches the low
voltage threshold, the normally open relay will energize, closing the contacts and lighting
the red L.E.D. on the panel. When battery voltage rises to the reconnect threshold,
indicating charging has occurred the contacts will open.
