| Error Indicator | Possible Cause | Solution (Step-by-Step) | |----------------|----------------|--------------------------| | ERR LED solid red | Overcurrent on output | 1. Disconnect power. 2. Check Y0-Y19 for short circuits. 3. Reduce load. 4. Restart. | | ERR flashes 3 times | SE36 communication timeout | 1. Verify baud rate & slave ID match master. 2. Check A/B wiring for reversal. 3. Add termination resistor. | | PWR LED off | No power or internal fuse blown | 1. Measure voltage at L/+ and N/-. 2. Check external fuse. 3. If OK, contact support (internal fuse not user-replaceable). | | Analog input reads incorrectly | Wrong mode (voltage vs current) | Set P50 correctly. Also check jumper J5 (if present) inside the unit. | | Unit does not retain settings | Battery low (if model has RTC) | Replace CR2032 battery on main board (observe polarity). |
