🔍 Troubleshooting Suggestions

Error code T indicates that the power supply board has a signal jam, which is a definitive hardware failure. As a result, the entire system cannot work anymore. In tandem with this code, the status light will be cycling and emitting different colors in sequence.

🪛 Repair or Replacement

Please kindly replace the power supply board after receiving this error code. Since the load cells are soldered directly to the circuit board, they must be replaced together as a complete assembly. This design offers better reliability, durability, and signal consistency than pin-connected alternatives.

After the replacement, please recalibrate the weight sensor using Popur S7 App → Device Page → Top-right icon for Settings → Scale → Recalibrate scale → Confirm, or follow this video guide: https://youtu.be/H8SOgcMz7Wo.

🚩 Special Case for Incompatible Software after Replacement

If the new power supply board you received is baked with firmware 3.6.0 or earlier version, it will be incompatible with the rest of the system. While the core features remain functional, including auto-clean and App 2.0.0 version, a suite of new functionalities won't work.

The easiest way to tell this info is by turning on the Auto power-cycle feature in the Popur S7 App → Device Page → Top-right icon for Settings → Spin → Auto power-cycle. Then, reboot the machine to see whether or not it automatically power cycles. If not, the new power supply board is on legacy firmware.

To address this incompatibility, simply update to firmware 4.0.0 or onwards in the Popur S7 App → Device Page → Top-right icon for Settings → Firmware update. If there is no newer version to install, please contact us so that we could manually push over a new version for you to install.
