Operation:
The gauge needs only the red and black wires connected to light up. The
gray wire connects to the sender.
The sender must be Dakota Digital part
SEN-04-1 or SEN-04-2.
Sending units from other manufacturer’s will cause
incorrect readings. SEN-04-1 has 1/8” NPT threads and SEN-04-1 has 3/8” NPT
threads. If other thread sizes are needed, an adapter fitting should be used to
change the thread size. If the gray wire is not connected, the display will show
“EE”. If the gray wire is shorted to ground, the display will show “--”. When the
blue wire has 12 volts, it will dim the display for night viewing. The yellow wire
will provide a ground output when the gauge reading is outside the high warning
limit.
Setting the warning limit:
The high warning limit can be set to different values. Once it has been
set, it is stored internally so that the gauge will retain the values even when the
gauge does not have any power. This value can be set and reset as many times
as desired. The procedure for setting the warning limit is as follows:
1.
Make sure the key is off so the gauge is not powered.
2.
Press and hold the ‘SET’ button. This is located behind the hole located on
the back side of the gauge as shown in figure 1.
3.
Turn the key on while the ‘SET’ button is being held.
4.
Release the button. The gauge should show ‘HI’ and then switch to a reading
between 165 and 300 (74 and 150
°
C).
5.
Turn the warning adjustment pot until the desired high temperature limit is
showing. The adjustment will then 3/4 rotation from stop to stop. Do not
force it past either stop.
6.
Press and release the ‘SET’ button. The gauge should show ‘--’. The new
warning limit is now stored.
7.
Turn the key off. The gauge will now operate normally when powered up
again.
