Motor PID Setting Mode
Hold down Right Split Weight® and Stop key at power up.
Press the CenteringCheck® key (up to 4 times) to select the type of spin.
1. Wheel with tire balance spin (Note: Some values are multipliers, not
actual PID values).
2. Quick-Thread®
3. Bare spindle.
4. Wheel with tire servo.
For adjusting PID constants in the field, Proportional term (P) is shown in “A” digits,
Integral term (I) is shown in “W” digits, and Derivative term (D) is shown in “D” digits.
Use the appropriate knobs to adjust the constants for one or more spin types.
Press the CenteringCheck® key once more (“-5-“ shown in left digits) to display the
balance spin target RPM. Use the “D” knob to adjust if necessary.
To temporarily store the new PID constants and RPM (until power is turned off),
press the CenteringCheck® key while the target RPM is displayed.
To permanently store the new PID constants and RPM, press the Enter key while the
target RPM is displayed. Turn power off and back on to exit this test.
Factory settings for PID and RPM:
“-1-“ 75, 70, 0
”-2-“ 20, 8, 15
”-3-“ 10, 15, 0
”-4-“ 125, 140, 61
”-5-“ 300
Switch Test
Hold Right and Left Split Weight® keys during power up. Press “Next” key to begin
showing diagnostic variables.
Dial the “D” knob to diagnostic item number 36. Zero will be displayed on the right
weight digits.
Press all keys and close all switches. Each switch closure should be followed by a
beep indicating that the switch is functioning.
Dial the “D” knob CW or CCW to exit the switch test.
Display Test
Hold Stop key and Oz/g key during power up.
All of the LEDs will light and stay lit until the spindle is rotated or the hood switches
change state. Balancer will not exit the test at the press of a key, like the normal
merchandising display.
Resetting Setup Items to Default
To automatically reset all setup items to factory defaults hold down “Setup/Cal” key
during power up.
Settings will be stored in EEPROM memory and will remain defaulted when power is
turned off.
