6608 (A8) No response frame error

What does 6608 (A8) mean?

This error indicates that there's a continuous failure in data transmission, meaning the system is not receiving a response 'frame' or packet. This can be caused by continuous noise, a decline in transmission voltage/signal due to line issues, or a malfunction in the error source controller.

• Continuous failure of transmission due to noise etc.
• Decline of transmission voltage/signal caused by tolerance over on transmission line (e.g., too long, unmatched types).
• Decline of transmission voltage/signal due to unmatched transmission line types.
• Accidental malfunction of error source controller.

Click steps to track your progress.

1. 1

   Turn off the power to the entire system at the main circuit breaker.

2. 2

   Check all transmission lines for proper length (max 200m / 656ft total, max 12m / 39ft for remote controller line) and correct wire type (CVVS, CPEVS, or MVVS with 1.25mm² / AWG16 or more).

3. 3

   Inspect for any potential sources of continuous electrical noise that might be interfering with communication.

4. 4

   Ensure all connectors are firmly seated.

5. 5

   Restore power. If the problem persists, a qualified technician should check transmission voltage and diagnose controller malfunctions.
