| Parameter | Value | |-----------|-------| | Supply voltage | 85–265V AC, 50/60Hz, 12VA max | | Input impedance | > 1MΩ (voltage), 250Ω (current) | | Accuracy | ±0.1% of reading ±1 digit | | Operating temp | -10°C to +55°C | | Enclosure rating | IP65 (front), IP20 (rear) | | Dimensions (WxHxD) | 96 x 96 x 85 mm | | Weight | 0.45 kg |

The manual includes a parameter like PASS or COD . Set a non-zero value. Once set, users must enter that code to modify parameters. The default code is often 0 (disabled) or 1234 . : Over time, the continuous vibrations from the

| | Likely Cause | Solution | | :--- | :--- | :--- | | No Power (no LEDs) | Blown fuse, no incoming power, or internal failure. | Check your sealer's power cord and fuse. Use a multimeter to verify voltage at the controller's input terminals. If voltage is present, the controller may have failed internally. | | Sealer Won't Heat | Faulty thermocouple, failed heating element, or defective internal relay in the controller. | Test the heating element for continuity. Test or replace the thermocouple. If both are functional, the controller's relay is likely faulty and the controller needs replacement. | | Sealer Overheats | Stuck relay in the "on" position or shorted switching device. | This is a safety hazard. Immediately turn off the machine. The controller has failed and requires immediate replacement. | | Inaccurate Temperature | Incorrect thermocouple type, drifting components in an aging controller. | Ensure the thermocouple is the correct type. Consider replacing the controller, as analog components can drift over time. |
