BIM CONNECTION
STATUS LED
This LED is located at the corner of the control box, next to the GROUND terminal. The
LED is used for diagnostics and for a quick visual check if power is present.
•
A steady flash, on and off, about twice a second indicates the system is powered and
operating normally.
•
On steady indicates low power, below 9V, at the POWER terminals, or that the system is
in DEMO mode.
•
A short flash once every four seconds indicates the CONSTANT POWER terminal is
powered and the system is in stand-by mode.
•
Not flashing or lighting indicates loss of power or ground.
GROUND
This is the main ground for the display system. A wire should be run from this terminal to
the vehicle’s main chassis ground
.
Use 18 AWG or larger wire to ensure sufficient grounding.
Proper vehicle grounding is extremely important for any gauge (or electronics) to operate
correctly. The engine block should have heavy ground cables to the battery, frame, firewall, and
body. Failure to properly ground the engine block or the control box can cause incorrect
or erratic operation.
CONST. POWER
Connect the CONST. POWER terminal to a +12V power from the fuse panel that is “hot”
all of the time, or a fussed wire (5-20 amp) direct to battery power. This terminal should have
power all of the time. The co12V supply source should be a fused 5 - 20 amp circuit, the
system draws less than 1 amp, so sharing an existing constant power circuit will generally be fine.
Use 18 AWG wire to ensure the system receives a sufficient power feed. This terminal keeps the
clock memory as well as returning the needles to zero when the system is shut off.
