INTRODUCTION

The Auto Charge D is a dual battery system automatic battery charger designed specifically for vehicles with a DDEC control and a separate engine battery.

The engine battery on DDEC equipped vehicles presents a unique problem. While it is desirable to have a charger to maintain this battery in a fully charged condition, this battery is relatively lightly loaded. It is never required to operate any of the vehicle mounted accessories and is rarely discharged. The vehicle, however, may have multiple batteries which may be heavily loaded and require considerable charging. The unequal loading may cause either overcharging the engine battery or poor charger capacity utilization. The Auto Charge D specifically addresses this problem and automatically recharges and maintains both vehicle and engine batteries.

The battery charger features are:

Independent charge controls for each battery

Electronic remote sensing of true battery voltages,eliminates the need for sensing wires

Automatic current limiting for both engine and vehicle batteries

Built-in5 ampere BATTERY SAVER

Remote dual battery charge/condition indicator

Power “ON” LED indicator

BATTERY SAVER overload indicator

DESCRIPTION

Independent Charge Controls & Electronic Remote Sensing

The charger contains two independent charge controls, one for each battery. This allows each battery to be independently charged while maintaining battery isolation. Each battery voltage is remotely sensed, electronically, eliminating the need for four sense wires. Each of the charge controls is completely automatic and stops charging the battery when it is fully charged. There is no trickle charge and therefore no danger of overcharging and water boil-off.

Automatic Current Limiting

The charger contains automatic current limiting for each output. The vehicle output is limited at 25 amperes while the engine output is limited at 3 amperes. This provides the higher current to the larger batteries where it is needed.

BATTERY SAVER & INDICATOR

A 5 ampere BATTERY SAVER is built into the charger. When connected as shown in the installation wiring diagram, loads on the vehicle 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 5 amperes.

WHEN A BATTERY SAVER OVERLOAD OCCURS THE BATTERY SAVER OUTPUT IS INTERRUPTED BY AN AUTOMATIC THERMAL CIRCUIT BREAKER. THIS CIRCUIT BREAKER WILL CONTINUALLY CYCLE THE OUTPUT ìONî AND ìOFFî UNTIL THE OVERLOAD IS REMOVED. WHENEVER THE BATTERY SAVER OUTPUT IS ìOFFî THE

OVERLOAD INDICATOR IS LIT.

Remote Dual Battery Charge Condition Indicator

This remote indicator shows the charge condition of each battery in 10 levels for “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 charged with an external load of 1.5 to 5 amperes across its 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 vehicle battery when the A.C. power is “OFF”.

INDICATOR INSTALLATION

1.Locate Indicator in a convenient place on the vehicle.

2.Place the template in position and center punch in 4 places.

3.Drill holes as shown.

5.Cut out square hole.

6.Connect wiring to charger using butt connector supplied.

7.Install as shown.

8.Insert 4 #6-32screws and tighten, (CAUTION Do not over tighten because you will bend the plastic bezel and brake the watertight seal).
