Troubleshooting:

Q: The Clamps are not engaging:
- Check the Air Compressor and make sure it is on.
- Check the Air Lines to make sure they are not kinked.
- For the Z Series, see if the Mat Clamp Pressure Knob on the Control Panel is set to the low setting.
- For the Z Series, make sure the Clamp Pressure Adjustment on the Control Panel isn’t set too low.
- Check the ECU/Driver Pack connections into the back of the Control Panel, Gantry and the Computer and make sure they are tight.
- Turn off the ECU/Driver Pack and close the software.
  - Turn on the ECU/Driver Pack and restart the software.
- Check the Clamp Actuator Valve in the Air Valve Assembly located in the Gantry.
  - The Air Valve Assembly may need to be replaced.
Q: The Head is not Lifting/Lowering to the Board:
- Check the Air Compressor and make sure it is on.
- Check the Air Lines to make sure they are not kinked.
