Problem
Resistive sensor rotator missing
Stepper thermal warning
Stepper thermal shutdown
Stepper open coil
Solution
If fail (open) => replace linear sensor
cable
3. Replace the resistive position
sensor
4. Replace i3000.
1. Check that the wiper is pressing
mechanically onto the surface of an
resistive angle sensor.
If fail => replace wiper and spring
• Check connections:
2. Check connections:
* J2001, J1013
If fail (open) => replace rotating
sensor cable
3. Replace the resistive angle sensor
4. Replace i2000.
Let the device cool down.
1.1 For pivot, linear:
Replace i3000
1.2 For rotation, sensor swap:
Replace i2000
1.3 For scan motions:
Replace i4000
2.1 For collimator:
- Replace collimator
- Replace i2000
2.2 For laser lift motion:
- Replace horizontal 3D laser
assembly
- Replace i4000.
1 For pivot, linear:
1.1 Check connections:
* J3011, J1015, J1016
If fail (open) => replace linear and
pivot high torque cable
1.2 Replace motor
1.3 Replace i3000
2 For rotation:
2.1 Check connections:
