1 Overview

  “TM4810034 temperature control system”temperature control panel is designed for the semiconductor cooler to adjust the environment temperature, it can control the semiconductor when it works under the condition of cooling or heating. The temperature control panel can not only adjust the environment temperature, but also monitor the inner and external fan, temperature sensor, the situation of over pressure or under pressure and so on. If there is any abnormal, it will report alarm message through relay dry contacts. Real-time monitor toward the working mode of semiconductor is implemented by RS485 serial port, upper machine software and connection of communication port for temperature control panel.

4 Product Function
4.1 Self Test

     When power on, the temperature controlling panel starts to self test: temperature sensor- internal recycle fan- extrinsic cycle fan- TEC refrigerate. When self testing, the green light is blinking.If hardware failure, the red light will blink. When self testing finish: a.No failure warning, the controlling panel works normally. b. If there is a alarming, the green light will be off and the red one will be blinking.
4.2 refrigerate
     When temperature inside cabinet higher than the opening point of refrigeration, the refrigeration operation starts to run; when temperature lower than opening point, it stops. When setting the point, the stopping point should be lower than the opening one
