Failure on the P6 sideshift potentiometer in the fingertips / joysticks group.
Check the voltages on the potentiometer at rest
Enter the TESTER function in the menu MAT. HANDLING and check the SIDESHIFT POT and SIDE-
SHIFT SWITCH parameters.
Conditions of rest:
- SIDESHIFT POT = 2.5 ± 0.2 V
- SIDESHIFT SWITCH = OFF
If the conditions of rest are different the potentiometer could be mechanically jammed or defective.
Check:
• exchange the sideshift potentiometer with the tilting potentiometer (fingertips version) and verify the
correct operation through console
• exchange the sideshift potentiometer with the lifting potentiometer (joystick version) and verify the
correct operation through console
If the alarm persists replace the logic unit.
E5 BAD IV POT

Failure on the P7 4th way potentiometer in the fingertips / joysticks group.
Check the voltages on the potentiometer at rest
Enter the TESTER function in the menu MAT. HANDLING and check the IV WAY POT and IV WAY
SWITCH parameters.
Conditions of rest:
- IV WAY POT = 2,5 ± 0,2 V
- IV WAY SWITCH = OFF
If the conditions of rest are different the potentiometer could be mechanically jammed or defective.
Check:
• exchange the 4th way potentiometer with the sideshift potentiometer (fingertips version) and verify the
