Auto Charge 1000 Instructions

Charge Controls & Electronic Remote Sensing
The Auto Charge 1000 contains a precision voltage controller to maintain the battery’s charge. Automatic electronic remote sensing measures the true battery voltage, eliminating the need for the additional sense wires. The output current of any charger is inherently a series of pulses whose frequency is determined by the power line frequency. Therefore their are brief intervals during which no charging current flows. During this brief interval the Auto Charge 1000 measures and stores the battery voltage. This battery voltage is compared to a standard and any error is detected and used to control the charger output at the desired level. Their is no “trickle charge” and therefore no danger of overcharging and water boil-off.

Automatic Current Limiting
When batteries are severely discharged, some battery chargers can be overloaded due to the high charging current required. The Auto Charge 1000 contains an automatic current limit. This circuit limits the output current to the rated 15 amperes when charging a deeply discharged battery or if the starter cranks the engine while charging. The current limiter thus eliminates the need for an ignition interlock circuit.

Introduction
The AUTO CHARGE 1000 is a compact, completely automatic, single channel battery charger designed for vehicles with a single battery system. The charger is ruggedized to withstand the shock and vibration encountered by vehicle mounted equipment.
The battery charger features:
• Electronic remote sensing of true battery voltages, eliminates the need for sensing wires
• Automatic current limiting
• Built-in BATTERY SAVER
• Remote battery charge/condition indicator
• Power “ON” LED indicator
• BATTERY SAVER overload indicator

Battery Saver & Indicator
A 3 ampere BATTERY SAVER is built into the charger. When connected as shown in the installation wiring diagram, loads on the battery such as radios and rechargeable hand lights are automatically switched to the BATTERY SAVER when power is applied to the charger. The BATTERY SAVER allows more efficient charging by removing these loads. A BATTERY SAVER overload indicator alerts the operator that the BATTERY SAVER load has exceeded 3 amperes.

WHEN A BATTERY SAVER OVERLOAD OCCURS:
a. Remove the loads for approximately two minutes
b. Reduce the load to 3 amperes or less
c. Reapply the load to the BATTERY SAVER

No fuses are required or provided as the BATTERY SAVER contains an electronic overload interrupter.

Remote Battery Charge Condition Indicator
This remote indicator shows the charge condition of the battery in 10 levels from “LOW CHARGE” to “FULLY CHARGED”. This device indicates a defective battery when a bar graph does not rise to the “FULLY CHARGED” level after an extended period of charging.

NOTE: If a battery is being discharged with an external load of 1.5 to 4 amperes across it’s terminals, the bar graph may move down 1 or 2 levels. This does not indicate a defective battery. To avoid this, connect all external loads to the BATTERY SAVER terminals.

Loads connected to the BATTERY SAVER will be powered either from the BATTERY SAVER power supply when the A.C. power is “ON”, or they will be connected to the battery when the A.C. power is “OFF”.
