| LED / Symptom | Likely Cause | Solution | |---------------|----------------|----------| | | Power supply failure (24V missing or shorted) | Check fuse, power supply unit, and wiring. | | ERR red blinking | Program checksum error or watchdog timeout | Re-download the program. Check for infinite loops in code. | | I/O LED on but actuator not moving | Output relay welded or load missing | Measure voltage at output terminal; replace relay (soldered on board). | | Modbus no response | Wrong baud rate or parity | Default is 9600, 8, N, 1. Verify with serial sniffer. | | Analog input reads erratic | Ground loop or sensor failure | Use isolated 24V supply; test sensor with multimeter. | control ciber 1.552
