Reading the Displays
Weight Displays - The two weight displays (one for the inner
plane, and one for the outer plane) are positioned with a wheel
cross section diagram. After spinning the wheel, the balancer
will calculate the weight needed and display it in these displays.
The display to the left of the diagram will show the weight to be
applied to the inner plane of the wheel and the display to the
right will show the weight for the outer plane.
Error messages and system messages will also be shown in
these displays.
Weight Position LEDs - Each weight display includes weight
position LEDs. Located between the weight display and the
diagram, these LEDs indicate the proper location for weight
application. After a spin, rotate the wheel until the center
position indicator LEDs flash. This indicates that the position
specified by the balancer for weight application is at top-dead-
center.
Display Messages - Both inner and outer displays will show
0.00 when the balancer is first turned on or after clearing the
memor y. The balancer may also display the following
messages:
Err - An error was detected after the start button was
pressed. The error is in one of the wheel measurements
entered into the balancer. Check your measurements and re-
enter as needed.
Err 3 - Circuit malfunction. Call the Hennessy Service
Department at (800) 688-6359.
Hood (hod) - The hood has been raised during the balanc-
ing cycle. The balancer will automatically brake to a stop. The
hood must be down with the safety interlock engaged for the
balancer to spin.
Hub - The hub nut has come loose. The balancer will auto-
matically brake to a stop when the wheel is 13 inches or
larger in diameter. Retighten the hub nut and respin.
