Series II
HLY-3051 VOLTMETER
Introduction:
The Odyssey Series II gauges from Dakota Digital, Inc. incorporates the reliability and
quality of our standard gauges, along with several unique features and easy mounting. These
features include:
• Industry standard 2-1/16” gauge size.
• Weather-proof construction.
• A warning feature that flashes the gauge readout when outside operating limits.
• User adjustable warning points.
• Microprocessor stabilized readings.
• Quick-Start feature to provide accurate readings quickly after being powered up.
• Night dimming with lens label lighting.
• Non-Glare, high contrast lens.
• High Visibility VFD display for sunlight readability.
Operation:
The PWR terminal should be connected to a 12 volt accessory feed. The case provides
the gauge ground. Connect a ground wire to the screw at the bottom rear of the case. When the
DIM terminal has 12 volts, it will dim the display for night viewing. The SND terminal is the
voltage sensing input. To read the vehicle system voltage, connect this to the PWR terminal.
To read the voltage at a second battery or other remote location, connect a wire from the SND
terminal to the voltage to be monitored.
The voltage gauge will operate in the voltage range of 8.0 – 17.0 and read correct
between the voltage range of 1.0 - 18.0 volts. It has a user adjustable lower and upper warning
level. This can be set to indicate low voltage and overcharging conditions.
Setting the warning limits:
The SND terminal is used to enter and change the warning settings. You will need a
wire connected to the SND terminal that can be powered separate from the gauge.
1. To enter the set mode, turn the key on with the SND wire not powered. The gauge will
display “SEt”.
2. Power the SND wire. The gauge will display “ HI”. (If you wait too long the gauge will
exit the setup routine and you will need to repeat step #1).
3. Release the SND wire. The gauge will display a number between 13.9 and 16.9.
4. Each time you momentarily power the SND wire the number will increase by one.
5. When the desired high warning value is displayed, keep the SND wire powered for about
2 seconds. The gauge will display “ LO”.
6. Release the SND wire. The gauge will display a number between 9.7 and 12.6.
7. Each time you momentarily power the SND wire the number will increase by one.
8. When the desired low warning value is displayed, keep the SND wire powered for about
2 seconds. The gauge will display “--”.
9. Turn the key off.
