About this manual

This is the user manual for the LD-B10-C220Y dry transformer temperature controller, designed for rail transit applications. It explains how to install, operate, and maintain the device to monitor and control transformer temperatures. The controller uses Pt100 sensors to detect temperature, controls cooling fans, and provides alarm and trip outputs. Safety precautions are emphasized, including proper grounding, avoiding corrosion, and only qualified technicians performing operations. The manual includes wiring diagrams, installation steps, and technical specifications.

The device features an LCD display, RS485 communication, 4-20mA output, and is compliant with EMC/EMI standards. It is suitable for harsh environments and has been deployed in metro systems across China. The manual also covers fault handling and warranty information, including a 2-year product warranty or 18 months from purchase, with conditions for repair or replacement. This manual is written in Chinese.
