Introduction

The DCE provides accurate low cost instrumentation for 3
banks of batteries between 9.5 and 33 Volts.  The unit
displays voltage for three banks and amps or amp-hours for
your house bank.  It tracks all current entering and leaving
the house bank and applies Peukert's and efficiency factors.
You can set Low and High voltage alarms and Low Amp-
Hours Remaining alarms on the house bank. When activated,
the built-in 85 dB alarm will sound and the display will
flash.   The DCE outputs NMEA 0183 serial data or the data
line can be programmed as an external alarm output or as a
charger on-off control.  Five levels of backlighting can be
selected and all set-up, calibration constants and alarm
values are saved to non-volatile memory. The DCE comes
complete with a precision 500 amp shunt and is designed to
work with 50-500 amp 50mV shunts. (Unit must be
recalibrated if other than 500 amp shunt is used.)

Installation

Before starting the installation, please read this entire
section first. The instrument may be installed in a bulkhead
or in NEWMAR's Single or Dual  Universal Meter Panel
Blanks (contact factory). Remove the rear bracket, attach
wiring as explained in the following section, then reassemble
and install as shown in the diagram below. Finger tighten
the nuts that secure the bracket - do not use tools. (You may
use Lock-Tite to keep the nuts from vibrating loose.) Be sure
to slide the bulkhead gasket over the instrument body before
you install the instrument.

Drill a 2-1/8" (55mm) mounting hole (or use NEWMAR's
Single or Dual Universal Meter Panel Blanks) as shown in
FIGURE 1.

Bring the shunt wires, ground, and power lines out of the
mounting hole and through the large opening in the DCE
mounting bracket. Use a small flat-tip screwdriver to make
the connections to the screw terminal on the instrument case
back as shown in FIGURE 2 and FIGURE 3.
