INTRODUCTION
The Auto Charge D-PUMP PLUS 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 2000D specifically addresses this problem and automatically recharges
and maintains both vehicle and engine batteries.
The AUTO CHARGE D-PUMP PLUS operates an 091-9 air compressor.
With the selector switch in the AC position the compressor runs only when the
AC power is applied. With the selector in the DC position the compressor will
operate when the AC power is ON or OFF. In either position the compressor
operates from the vehicle’s batteries, the charger automatically recharging the
batteries as required.
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-in 5 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”.
