Fireye NX6300 F64 Profile Invalid after servo replacement, what to check?
I'm getting an F64 'Profile Invalid' fault on our Fireye NX6300 before startup. We just replaced a servo, and the fault subset is 101. What should I check first?
The Fireye NX6300 F64 'Profile Invalid' fault indicates that the selected fuel/air profile data does not match the current burner configuration, preventing the burner from firing. This is a safety measure often triggered by a servo replacement, deselected drive, or an unverified profile upload. The fault occurs before startup when a profile is selected.
Likely causes and checks
1Servo replaced
- Points to it
- The controller detects that a servo has been replaced, and the existing profile data no longer matches the new component, triggering a safety block.
- Check
- A qualified commissioning engineer must verify the new servo is mounted correctly and re-commission the profile, acknowledging all points up to high fire.
2Profile uploaded but not verified
- Points to it
- If the profile settings were restored from a PC or ComFire2, the controller requires verification on the burner itself before allowing operation.
- Check
- Verify the profile on the burner in Commission Ratio mode.
3Drive deselected
- Points to it
- Changes to option parameters may have deselected a drive, making the current profile invalid for the burner's configuration.
- Check
- Restore the drive selection or re-commission the profile without the deselected drive.
Next check: Given the subset is 101, which points to a servo replacement (profile number + 100), the most likely cause is that the new servo has not been properly commissioned. Ensure a qualified commissioning engineer re-commissions the profile, acknowledging every point up to high fire.
