| Error Message | Likely Cause | Immediate Fix | | :--- | :--- | :--- | | | Wrong COM port or baud rate mismatch | Check DIP switches. Run Auto-Configure. Reboot PC. | | "Verify failed at address 0x..." | Bad flash memory or power fluctuation | Cycle 990 power. Send program again. Replace internal battery. | | "Screen object corrupt" | HMI font library mismatch | Delete the offending screen object. Rebuild screen from scratch. | | "%AI Overscale" | 4-20mA sensor open or shorted | Check field wiring. In Cscape, set input range to "0-20mA" as a test. | | "CANbus Offline" | Terminating resistor missing | Add 120-ohm resistor at ends of CAN chain. |
