OPERATION AS DISPLAY AND MANUAL HEIGHT CONTROL SYSTEM
Operation:
The gauge needs only the RED and BLACK wires connected to light up. When the BLUE
wire has 12 volts, it will dim the display for night viewing.
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 or is
disconnected, the display will show “EE”. If the sender is shorted to ground, the display will
show “--”.
The display will flash whenever one of the displayed pressures is out of the warning set
limits.
When the system is first powered up it will be in the warning display mode. Four, three,
or two bag readings will be displayed depending on which senders are connected. If one of the
bag pressures is outside of the warning limits then that reading will flash and the warning output
will be activated. Moving the joystick up, down, left, or right will not do anything. Pressing the
joystick in and holding it for a couple seconds will switch to the tank display if the tank sender is
connected. Pressing and releasing the joystick will switch to the manual control display.
When in manual display if any of the pressures are outside their warning limits the
reading will not flash, but the warning output will be active. If the joystick is pressed and held to
display the tank pressure the system will always go back to the warning display mode when the
joystick is pressed again. The bags cannot be raised or lowered while the tank pressure is
displayed. If no switches are pressed for 8 seconds then the system will automatically switch to
the warning display mode.
The first manual control display has only one bag reading highlighted at a time. The bag
matching the reading highlighted can be raised by moving the joystick up or lowered by moving
the joystick down. Moving the joystick to the right or left will change which bag is highlighted.
Pressing and releasing the joystick will switch to the next manual control display.
The second manual control display has both front or both rear bag readings highlighted at
the same time. This screen will not be seen in two-bag setups. Moving the joystick up will raise
both bags and moving the joystick down will lower both bags. Moving the joystick to the right or
left will change which bags are highlighted. Pressing and releasing the joystick will switch to the
next manual control display.
The final manual control display has all of the bag readings highlighted. Moving the
joystick up or down will raise or lower all bags together. Moving the joystick left or right will have
no affect. Pressing and releasing the joystick will switch back to the warning display mode.
