LVI- Low Voltage Alarm and Interrupt
Designed for all lead acid batteries
INTRODUCTION:
The LVI is designed to prevent the over discharge of lead acid
batteries which is one of the leading causes of premature failure.
This includes, deep cycle, starting, AGM, and gel types. The LVI
uses visual, audible, and functional features to alert the operator
that the battery(s) are approaching harmful low levels so that
damage can be averted. The LVI is voltage specific and is
available in 12, 24, 32, 36, 48, 64, 72, and 96 volts. Other voltages
can be configured upon request.

INSTALLATION:
Mount the LVI where it can be protected from physical damage,
moisture, or extremely dusty areas.
Be sure the voltage of your LVI matches the batteries it will be
connected to. Wire the desired features of the LVI as shown in the
illustration.

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.

QUICK CHARGE
LVI (low voltage alarm and interrupt)
“LIMITED WARRANTY”
Quick Charge Corporation warrants the LVI for (2) years from the date of purchase. After the
warranty period, chargers returned to the factory for repair will be charged a minimum rate of
$25.00. Charger will be returned, freight and repair charges, C.O.D. unless other arrangements
have been made. This warranty covers all defects in manufacture and performance, provided the
unit is operated in compliance with manufacture’s operating instructions.
For repairs to be made at the Quick Charge factory, a charger and/or component(s) should be
sent, freight prepaid to Quick Charge at::
Quick Charge Corp.
Quick Charge, will at it’s option, repair or replace the charger or component in question. The
repaired item will then be returned, freight prepaid by Quick Charge. This warranty is void if the
charger or component have been altered, changed, or repaired by anyone not authorized by
Quick Charge, or if the charger or component, have been subjected to misuse, negligence, or
harsh environmental conditions. (Except those chargers designed for such conditions)
If returning the charger to the factory is not practic al, replacement parts may be shipped to the
customer for field repair at no charge. On parts such as circuit boards, the customer will be
required to return the board suspected to be defective to Quick Charge, freight prepaid. If such
defective parts are not returned, the customer will be invoiced for the repair parts. Field repairs
are made at the user’s own risk. “Authorization” by Quick Charge to repair refers to maintaining
the warranty only. Quick Charge assumes no responsibility or liability for field servicing, and shall
not be responsible for incurred travel or labor charges.
Quick Charge corporation shall not in any event be liable for the cost of any special, indirect or
consequential damages to anyone, product or thing. This warranty is in lieu of all other warranties
expressed or implied. Quick Charge neither assumes nor authorizes any representative or other
