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.
