7.6.13 Enabling of serial output RS232C
(option)
This option enables/disables the sending of the measured
unbalance and phase values to serial output RS232C.
Transmission speed
9600 baud
Data format 1 bit Start
8 bit Data
None parity
1 bit Stop
At the end of each unbalancing measuring spin, the balan-
cing machine transmits the data regarding the measured
unbalance. The items of data transmitted via serial line are
in ASCII format and are separated between each other by
the <cr> character (0x0d).
Sending sequence is as follows:
- 00000 <cr>
- Value of correction weight, left side <cr>
- Correction phase, left side <cr>
- Value of correction weight, right side <cr>
- Correction phase, right side <cr>
The first 5 zero bytes represents the start of transmission
message. The correction values are expressed in grams, in
steps of .1 gram.
The phase values are expressed in degrees, in the range
0 ÷ 359.
7.7 BALANCING SETUP
7.7.1 Unit of unbalance measurement
It is possible to select whether to display the unbalance values
expressed in grams or ounces.
7.7.2 Unbalance display pitch
This represents the display pitch of the unbalance and varies
according to the unit of measurement selected. The selection
“5 g” (1/4 oz) enables display of the correction values on both
sides such as to bring the static unbalance to 0 (theoretical). It
is recommended to preset this function as standard use of the
machine as it improves the balancing quality. The computer
makes a complex calculation which allows cancelling the
residual static unbalance by varying the value and position of
the counterweights fixed in steps of 5 grams (1/4 oz).
7.7.3 Tolerance
This is the unbalance threshold below which the word “OK”
instead of the unbalance value appears on the screen at the
end of the spin.
7.8 CORRECTION METHOD
One of the two possible correction methods can be selected
based on the specific requirements of the customer.
7.8.1 Standard correction method
The wheel balancer considers the unbalance within tole-
rance when the value of each single plane is lower than the
tolerance set.
7.8.2 External plane correction method
If correcting with adhesive weights, the unbalance is considered
within tolerance when the recalculated external plane weight
(clip-on weights) is lower than the tolerance set.
Additional windows appear on the screen always displaying
the residual external plane value (clip-on weight):
7.9 STATIC ALWAYS ENABLED
Simultaneous display of the selected correction plane unba-
lance as well as STATIC unbalance can be enabled/disabled.
The static screen can be selected at any time by pressing
on the measurement screen and selecting the static
weight.
7.10 SPECIAL FUNCTIONS
7.10.1 Presetting the customer and user
name
The machine can be customized by presetting:
a) The name appearing on the Initial screen (screen-save).
7.10.2 Wheel Balancing machine SELF TEST
An automatic self-diagnostic cycle is provided for easier
trouble-shooting (
Consult the extraordinary mainte-
nance manual or contact Technical Service).
