Selecting Balancing
Options
Hood Start
The balancer can be set to automatically start the spin
cycle as soon as the hood is lowered completely and the
hood safety interlock systems are engaged. Press and
hold the SHIFT key and press 3. To return the balancer to
normal mode, repeat the key sequence.
Round Off
The default weight measurement on the balancer is 0.25
ounces. The balancer can be set to a non-Round Off mode
that displays weights in 0.01 ounce increments. Press and
hold the SHIFT key and press 6 to toggle between the
Round Off and non-Round Off modes.
Ounce/Gram
In the default mode, the balancer will operate in ounces.
The balancer can be set to operate in grams by pressing
and holding the SHIFT key and pressing 9. Toggle back to
ounces by using the same key sequence. LEDs on the
control panel indicate which weight measurement is cur-
rently selected.
Operator A/B
Two operators can utilize the balancer without clearing or
changing each others data. This is handy when one opera-
tor is running the Match Mount procedure and the other
operator needs the balancer. If operator A is at a point in
the Match Mount procedure where the wheel is removed
from the balancer, operator B can access the machine by
switching to the other operator memory. When B’s bal-
ance is complete, he can toggle the machine back to A’s
memory. All of operator A’s data is still present, and the
Match Mount procedure can be continued without having
to start over. Press and hold the SHIFT key and press 7 to
toggle between the 2 operator memories. LEDs on the
control panel indicate which operator memory is in use.
Clear
This function clears the data in the currently selected
operator memory only. The other memory is unaffected.
Press and hold the SHIFT key and press 2 to clear.
Blank Rim
This feature blanks out the wheel diameter measure-
ment on the control panel display. The balancer continues
to use the measurement even though the display is blank.
This feature is typically utilized when the customer is with-
in view of the balancer, and may become concerned by
the measurement shown for the wheel diameter (typical-
ly when metric or odd size wheel diameters are displayed).
Press and hold the SHIFT key and press 4 to blank the dis-
play. Repeat the key sequence to reactivate the display.
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 sec-
tion diagram. After spinning the wheel, the balancer will
calculate the weight needed and display it in these dis-
plays. 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 appli-
cation. After a spin, rotate the wheel until the center posi-
tion 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 memory.
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 bal-
ancing 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
automatically brake to a stop when the wheel is 13 inches
or larger in diameter. Retighten the hub nut and respin.
