MAN# 650094B
Setting the warning limits and sender setup:
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 momentarily grounded while you watch the gauge. 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 not grounded. The gauge wil
l display “SEt”.
2.
Ground the SND wire. The gauge will display “Snd”. (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 the current setup. “40F” is for SEN-1043
F,
“20C” is for
SEN-1043
C,
“29F” is for SEN-1044 °F, and “14C” is for SEN-1044 °C. “30F” and “15C” are for sender
SEN-1041.
4. Each time you momentarily ground the SND wire the setup will change.
5. When the desired setup value is displayed, keep the SND wire grounded for about 2 seconds. The gauge
will display “ HI”.
6. Release the SND wire. The gauge will display a current high temperature warning point. The adjustment
range varies depending on the sender selected.
7. Each time you momentarily ground the SND wire the number will change.
8. When the desired high warning value is displayed, keep the SND wire grounded for about 2 seconds. The
gauge will display “--”.
9. Turn the key off.
