INTRODUCTION
The Auto Charge D-PUMP PLUS is a dual battery system automatic bat-
tery charger designed specifically for vehicles with a DDEC control and a sepa-
rate engine battery.
The engine battery on DDEC equipped vehicles presents a unique prob-
lem. 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 over-
charging 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 auto-
matic 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.
