Lighting Mode
(Region B Color)
This gauge allows the dial lighting to operate in two modes, Full On or Dimmable. Factory default is Full On.
Full On: In this mode, the white lighting wire is ignored. The gauge dial lighting is always on at full brightness. (unless you select NO color
when setting the Backlight Color). If using Full On mode, white wire hook-up is not needed.
Dimmable: In this mode, the white wire is used to set the intensity of the dial lighting from full brightness down to off.
To change the Lighting Mode:
With power off, press and hold the PEAK button. Apply power to the gauge. Release the PEAK button and the dial face will illuminate with
either white lighting or blue lighting. Press and release the PEAK button to toggle between Full On (dial is illuminated white) and Dimmable
(dial is illuminated blue). Once you have selected the desired mode, don't press any buttons for about three seconds. The dial will flicker white
several times to indicate the desired setting has been saved and the gauge will return to normal operation with your new mode selection. Mode
selections are saved when power is off.
Data Logger Output
This gauge is equipped to output the sensor signal to an external data logger system. This feature allows you to use the same sensor for both
the gauge and the data logger. With this gauge, it is not necessary to install two sensors to measure the same function.
To use this feature, you must have a data logger system installed in the vehicle and connect the data logger output from the gauge to the data
logger. Pins number 4 (black wire, ground) and 8 (yellow wire, sensor signal) in the connector on the back of the gauge are the data logger
sensor signal and ground connections that must be connected to the data logger. After connecting the gauge to the data logger, refer to your
data logger instruction on how to calibrate the data logger to use the signal
Gauge Reset
It may be desired to reset the gauge. This clears programmable settings to a system default.
With power off, hold in both buttons. Apply power to the gauge, wait two seconds,
and release both buttons. The dial face will flicker white several times and return to
normal operation. At this point, the gauge has been reset.
Reset Settings:
High Warning Set Point: Max Value
Low Warning Set Point: Lowest Value
Peak: Lowest Value
High Warning Color: Red
Low Warning Color: Green
Backlighting Color: White
Lighting Mode: Full On
High Warning Pro Control State: Active High
Low Warning Pro Control State: Active Low
High Over Warn Set Point: Max Value
Low Over Warn Set Point: Lowest Value
Pro Control Active States
The active region for Pro Control outputs are user configurable. For example, consider a pressure gauge with a low warning set point at 20
PSI . The gauge can be configured so the associated Pro Control output is active when the pointer falls below the set point [less than 20 PSI]
(active low) OR when the pointer is beyond the set point [greater than 20 PSI] (active high). Likewise, consider a pressure gauge with high
warning set point at 95 PSI. Again, the gauge can be configured so the associated Pro Control is active when the pointer falls below the set
point [less than 95 PSI] (active low) OR when the pointer progresses beyond the set point [greater than 95 PSI] (active high).
To change the active state:
With power off, press and hold the PEAK button. Apply power to the gauge. Release the PEAK button. Press and release the WARN button.
The gauge is now in Active State Set Mode. The pointer will point straight up at the value in the top center of the dial. Press and release the
WARN button to toggle back and forth between the low and high warning point active state modes. Doing so will cause the dial to change back
and forth between green and red. When setting the low warning active state the dial face will be green. When setting the high warning active
state the dial face will be red.
Once the designated warning mode is selected (green or red) press and hold the WARN button to toggle between active high and active low.
As you hold the button the pointer will continuously sweep from the left of center and to the right of center pausing at each side. Left of center is
active low and right of center is active high. Release the WARN button when the pointer is in the position of the desired active state. Once you
have selected the desired state, don't press any buttons for about three seconds. The dial will flicker white several times to indicate the desired
setting has been saved and the gauge will return to normal operation with your new state selection. State selections are saved when power is off.
NOTE: The Pro Control Active State does not
affect the color of each dial region.
