Troubleshooting
Set-up and installation of the QC Qualifier is simple and easy. Just follow the display prompts. Remember to let go of the throttle when the
display reads, "COMPLETE" after any step in the set-up. However, if the unit does not recognize the set-up, or recognize the tool or the tool being
in cycle, check the following:
1. Did the supply air pressure drop below the initial setting?
Remember to set the regulator to 5 psi below the available maximum supply. If supply drops, re-teach the PSET at the new pressure.
2. If, after repeated set up attempts, "CHANGE ORIFICE" shows on the screen of the QC200 box:
This means that the venting signal is weak. Check the following:
• Does the tool vent the excess air after shut-off? The tool must vent the excess air in order to function with the QC Qualifier.
• Is the tool a shut-off tool? If not, use a QC100 box instead.
• Is the tool running at the proper air pressure? (see point 1 above)
• Is the proper flow screw installed in the bottom of the RSM?
- Smallest screw:
- Med screw:
- Longer screw:
3. Is the tool shutting off OK?
Check the tool for proper operation and re-teach the PSET.
4. The lights don't always come on.
Check that the hose size and length is proper for the tool being used. If the air hose is too large the venting signal may not be getting
through by the time the operator releases the throttle. Change to a shorter or smaller air hose.
5. The QC Qualifier doesn't respond to the keypad.
Check that the LOCKOUT feature is not enabled, and if so, disable it. If there is still no response, the ribbon cable inside the unit is probably
OFF. Open the case and reinstall properly.
6. When using QC100 box, the tool is sluggish.
Check that the correct flow screw is installed and that the air supply is sufficient so that the pressure drop when the tool is running is not
greater than 10 PSI from the static pressure. If it is, either the air supply to the RSM is too low in volume or the RSM is too small for the tool.
