MAN# 650061
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. The headlights should be off or the DIM terminal
unhooked so that it does not interfere with the setup.
1. To ente
r 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 wil
l 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.
