The air pressure gauge will read wet or dry air pressure. The sender used for this
gauge is an oil pressure sending unit, so it is compatible with air, water, oil, and fuel. The air
pressure gauge will operate and read correctly between the pressure range of 0 - 145 psi
using the SEN-03-1 senders and 0-400 psi using the SEN-03-5 senders. The gauge has a
user adjustable low and high warning level.
Operation:
The gauge needs only the PWR and GND terminals connected to light up. When the
DIM terminal has 12 volts, it will dim the display for night viewing. The R-R, L-R, R-F, L-F,
and TNK terminals are for the pressure senders. The senders must be Dakota Digital part
SEN-03-1 or SEN-03-5. Sending units from other manufacturers will cause incorrect
readings. SEN-03 has 1/8" NPT threads. If other thread sizes are needed, an adapter fitting
should be used to change the thread size. If a sender is giving an incorrect reading, the
display will show "EE". If the sender is shorted to ground, the display will show "--".
The display will flash and the warning output will be set whenever one of the displayed
pressures is out of the warning set limits.
Using external warning indicators:
The WRN terminal provides a ground trigger whenever any of the senders are outside
the set limits. Low current indicators (less than 1/4 A) can be activated directly by connecting
their power wire to 12 volts and connecting their ground wire to the WRN terminal.
For higher current buzzers or lights, a relay will need to be used to switch the indicator
on. Dakota Digital's RLY-1 30A relay may be used for this. One of the coil wires should be
connected to 12 volts and the other coil wire connected to the WRN terminal. When the
gauge is outside its limits, the relay will turn on. The relay contact wires can be used to
switch the higher current.
