MAN#650065 rev. AION-20 AMP CURRENT GAUGEWiring:PWR - connect to fused, switched, 12 volt power (an accessory terminal will work for this)DIM - connect to the tail light circuit (when terminal has +12V, gauge will dim)SND - connect to the Output terminal from current sensor.GND/Gauge case - connect to a main ground location. The sensor and gauge should have a commonground wire to ensure accurate readings.Earlier style sensors have the following color code: RED – power, GREEN – output, BLACK & WHITE – ground.Mounting:The gauge requires an oval hole 1-7/16” high x 3-1/16” wide. It should be inserted into the opening from the frontand the 2 L-clamps will be installed from the back. Tighten a nut on each of the L-clamps so that the gauge is secure.Gauge depth to the back of the case is 1”. Gauge depth including the mounting studs is 1-7/8”.Display update choices:FSt (fast) - The display is updated 10 times per second. (default setting)SLO (average) - The display is averaged over one second.HLd (Peak Hold)- The display uses the fast rate and the highest current reading will be held for up to ½ second.• The amp current gauge will operate and read correctly from 3 – 250 Amperes. The sender has an opening which thecable to be monitored must pass through. An arrow on the sensor points towards the end of the power wire leading tothe load.• The sender must be Dakota Digital part SEN-20-3. Sending units from other manufacturers will cause incorrectreadings. The output of the sensor is linear with 0V at 0A, 5V at 250A, and 10V at 500A.Setting the update speed:The SND terminal is used to enter and change the warning settings. You will need a wire connected to the SNDterminal that can be connected to power while you watch the gauge. The sender must be disconnected from the gaugewhile this is done. The headlights should be off or the DIM terminal unhooked so that it does not interfere with the setup.1. To enter the set mode, turn the key on with the SND wire powered. The gauge will display “SEt”.2. Disconnect the SND wire. The gauge will display “SPd”. (If you wait too long the gauge will exit the setup routineand you will need to repeat step #1).3. Power the SND wire. The gauge will display the current update speed (SLO, FSt, or HLd).4. Disconnect the SND wire.5. Each time you momentarily power the SND wire the speed setting will change.6. When the desired update speed is displayed, keep the SND wire powered for about 2 seconds. The gauge willdisplay “--”.7. Turn the key off.
