Notes
•
The values displayed are independent of the set dimensions.
•
With the wheel stationary, the measured data can be displayed alternately by pressing
Enter.
•
It is possible to run additional spin cycles while still in the program.
•
To exit from the program (and the service environment) press F.
The program is used for:
checking that the displayed values are within the correct range:
-
phase difference
F
from -2.0 to +2.0
-
inside pickup signal
I
from 200 to 280
-
outside pickup signal
E
from 110 to 170
-
signal amplifier calibration
from 55.8 to 57.8
-
n. rejected periods
from 0 to 6
97 Display search circuit board operation (encoder).
Selecting the program results in the machine displaying:
-
message "Pos" on the LH display;
-
a numerical value from 0 to 255, depending on the shaft angle, on the RH display.
If the program is evoked immediately after the machine is switched on, the display reads "Pos
rot" to indicate the need for turning the shaft until the encoder zero reference passes in front
of the search circuit board: when this is done the message cancels from the display.
It is also possible to run a spin cycle (the displays read "97 GO") during which the pulses
measured by the search circuit board are totaled. On termination of the spin cycle the LH
display shows the expected count (384) and RH display flashes the actual total. These values
are displayed for 5 seconds after which the current angular position of the shaft is again
displayed.
To exit from the program (and the service environment) press F.
The program is used for:
checking the operation of the search circuit board. When the shaft is turned in either direction
the count should run continuously from 0 to 255, and at the end of a spin cycle the two
displayed values should coincide.
98 Display sensor operation
Selecting the program results in the machine displaying:
-
message "di" on the LH display;
-
the value in marks of the signal from the diameter sensor on the RH display.
As the sensor is retracted, the value is continuously updated
.
Press the keypad wheel data setting button, and the following display:
-
message "d" on the LH display;
-
the value in marks of the signal from the distance sensor on the RH display.
The value changes as the sensor is moved in/out.
Press the keypad wheel data setting button, and the following display:
-
message "Lr" on the LH display;
-
the converted voltage from the width potentiometer.
This value also changes as the outside sensor is moved in/out.
To exit from the program (and the service environment) press F.
