ELDEAN OPERATING MANUAL

4G6: DC Current & Voltage Metering
A DC volt meter in the power panel helps you monitor the load on
the ship’s batteries where: 1=Starting battery, 2=House battery,
3=Generator battery.
For the house battery only, the meter also indicates current in amperes while the
battery is being charged or discharged.
Pressing “V” on the DC meter takes you through the batteries in order, displaying their
voltage. Remember,
• 12.8 volts
is a fully charged battery at rest for at least ten minutes with no
charging or discharging;
• 13.2 volts
is a battery being “float” charged, i.e., it is fully charged but on a
proper charger to keep it that way;
• 14.2 - 14.5 volts
is a battery that is not fully charged, “bulk” charging to get it
charged;
• 10.5 volts
is considered a “dead” battery.
Pressing “A” on the DC meter puts it in the “Amps” mode to measure current for the
house battery only.
Pressing “C” on the DC Meter puts it in the “Capacity” mode to measure amp-hours
for the house battery only. In addition to the switches on the DC panel, there is an
Anchor Wlndlass circuit breaker/switch to the right of the helm. This switch should
be “ON” only when using the anchor windlass (see illustration to right); push the red
button to turn it off.
4H: Electronics
Eldean is equipped with an extensive array of electronic equipment, including several redundant systems. In the
overhead at the lower helm station, from starboard to port are the Onan Generator remote control, the Engine
Monitoring System, the Computank fuel and water monitor, an ICOM M127 Marine VHF radio, the Inverter control
and a Sea-Tel television system control. On the helm station itself is the Simrad Autopilot, a large Northstar Integrated
Navigation/Radar/Depth Sounder Display, and a Furuno Weather/GPS Display.
Redundant but networked systems at the upper helm station on the fly bridge include a matching Northstar display,
Furuno Weather/GPS unit, Engine Monitoring System, Autopilot control and Furuno Radar/GPS/Chartplotter, and ICOM
VHF radio.
Below is a brief summary of these systems. For details of their operation, consult the manuals found in the electronics
file wallet stowed under the lower helm seat.
The Anchor Windlass Circuit
Breaker is toright of the helm. It
is above the “GrandBanks” word.
The lever to which the arrow
is pointing turns it “on” when
pushed “in” to the right;
the red button turns it “off”.
A panel in the middle of the electrical control panel includes, in its right side,
the DC voltage & current (amps) meter 4. See the close-up to right...
