Quick Charge LVI - Manual (Page 3)

OPERATION:
As soon as the LVI is connected to the batteries it will audibly
signal the connection, and instantly begin to monitor.
The factory set alarm point is 1.75 volts per cell. When this point is
reached, the alarm will sound, and if the LED light is connected it
will begin to flash in sync with the tone. The lower the voltage
goes past 1.75vpc, the faster the alarm and flash will be. If the load
is lessened or removed, the alarm and flash will slow, or stop if the
voltage recovers above 1.75vpc. If the alarm is ignored, and the
voltage continues to fall to 1.6 vpc, and the lockout circuit is
connected, continuity will open on the two wires and remove the
load, or load controlling device. The capacity of this circuit is 15
amps. The lockout may be overridden by pressing the red button
which may be remoted with an additional button if desired. The
button must be held continuously to override, releasing it will
reinitiate the lockout. The use and location is important. If it is too
easy to override the lockout, the purpose of the LVI is defeated. If
on the other hand you are operating an electric vehicle and you
cannot make it back to an electrical outlet for recharge, the ease to
override the lockout may be very important.
ADJUSTMENTS:
Remove four screws holding the case together. If you want to raise
or lower the alarm start point you also adjust the lockout point, so
think of it as adjusting a window with the same differential
between alarm and lockout. Use a small screw driver and adjust the
pot as shown. This is best done by connecting the LVI battery
connections to a power supply where the adjustment can be made
accurately. You can also disable the alarm by cutting the diode as
shown.
