MAN#650063
Setting the warning limits and sender setup:
The SND terminal is used to enter and change the warning settings. Make sure the sensor is disconnected from
the gauge before attempting to enter setup. You will need a wire connected to the SND terminal that can be momentarily
grounded while you watch the gauge. 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 disconnected from the sensor and not grounded. The gauge
will display “SEt”.
2.
Ground the SND wire. The gauge will display “F” for Fahrenheit or “C” for Celsius. (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. Each time you momentarily ground the SND wire the temperature unit will change.
4.
When the desired unit value is displayed, keep the SND wire grounded for about 2 seconds. The gauge will display “
HI”.
5. Release the SND wire. The gauge will display a number between 121 - 229 (50 - 110°C).
6. Each time you momentarily ground the SND wire the number will change.
7. When the desired high warning value is displayed, keep the SND wire grounded for about 2 seconds. The gauge will
display “LO”.
8. Release the SND wire. The gauge will display a number between -36 - 71 (-38 - 22°C).
9. Each time you momentarily ground the SND wire the number will change.
10. When the desired low warning value is displayed, keep the SND wire grounded for about 2 seconds. The gauge will
display “--”.
11. Turn the key off.
