RELiON 12V INSIGHT FUEL GAUGE REMOTE BUTTON Installation Guide

RELiON 12V INSIGHT FUEL GAUGE REMOTE BUTTON

THANK YOU FOR CHOOSING RELiON
Please read through this installation guide before installing your RELiON Fuel Gauge and Remote Button. Should you have any questions concerning installation or use, please contact us at relionbattery.com

The InSight Fuel Gauge is a constantly backlit (no off switch) battery gauge that will show the state of charge (SOC) for up to 14 InSight Batteries connected in parallel. The InSight Remote Button will power on or off up to 10 InSight Batteries connected in parallel. (InSight batteries should never be connected in series.)

WHAT’S INCLUDED

FUEL GAUGE INSTALLATION

1. Power down the device in which the fuel gauge will be installed. Power down the first InSight battery in the string
   by tapping the power button once and then depressing the button until both LEDs on the battery show solid red (approx 6 seconds). Release button. The rest of the batteries in the string will also power off automatically.

2. Begin by locating the Fuel Gauge Cable Assembly. Attach the red ring terminal to the positive battery post and then the black ring terminal to the negative battery post on the first InSight battery in the bank.

3. Insert the CANBUS plug attached to the cable assembly wiring harness in the provided CANBUS SPLITTER.

4. Route the other end of the cable through the mounting bracket to the fuel gauge display destination on the vehicle dashboard and insert the four-pin cable plug into the back of the gauge. Important note – be sure to route the cable through the mounting bracket on the back side of the dashboard. Use zip ties to secure harness to vehicle to reduce strain on plugs!

5. Insert the fuel gauge through the dashboard and seat in the mounting bracket. Rotate the mounting bracket until the fuel gauge is held firmly in place on the dashboard. Installation is now complete. The fuel gauge will display current state of charge and other messages communicated by the battery bank.

FUEL GAUGE MEASUREMENTS

REMOTE BUTTON INSTALLATION

1. Begin by locating the Remote Button Cable Assembly. Route the connecting end through the button mounting destination hole, ending in the battery compartment. Use zip ties to secure the cable assembly to the vehicle to reduce strain on connections.
2. Attach the red ring terminal to the positive battery post and then the black ring terminal to the negative battery post on the first InSight battery in the bank.
3. Insert the CANBUS plug attached to the remote button cable assembly in provided CANBUS splitter on the first InSight battery in the bank.
4. Insert the CANBUS splitter in the CANBUS IN port on the first battery in the string.
5. Installation is complete. Test the function of the remote button by depressing the remote button until the InSight Batteries in the string power on (approx five seconds). LED 1 on all batteries will flash green.
   Note: Splitter is optional.
   See diagrams for more information on your battery setup.

FUEL GAUGE MESSAGES AND WARNINGS

The fuel gauge will display several messages throughout its operation cycle.

1. Upon startup the gauge will display the number of batteries detected. Make sure the number of batteries detected match the number of batteries in the bank.
2. During normal operation the fuel gauge will display the state of charge of the battery bank digitally as a percentage from 0-100%.
3. While the battery bank is above 20% state of charge the upper line of text will display the SOC while the second line displays the number of batteries and the remaining amp hours of the battery bank.
4. While the battery bank is below 20% state of charge the upper line of text will display the SOC while the second line will show “LOBATT” message.
5. While the battery bank is at or below 10% state of charge the upper line of text will display the SOC while the second line of text will flash “LOBATT” every 2 seconds.
6. If the setup is not done correctly and the gauge does not read any batteries it will display the message “no comms”.
