What should I do if the temperature and humidity controller of the constant temperature and humidity control device shows abnormal temperature?

What should I do if the temperature and humidity controller of the constant temperature and humidity control device shows abnormal temperature? In the course of operation, the user always encounters some faults and does not know how to solve them. In order to enable the user to quickly determine the faults and solve them quickly, the technician of Haida Instrument will introduce how to handle the temperature and humidity controller when the temperature is abnormal.  

First, troubleshooting steps:  

1. Check whether the over-temperature protector of the control panel is set at the position of 150 °C;  

2. Check whether the circulating motor of the engine room is damaged;  

3 , check whether the temperature of the solid state relay burns short circuit:

1 ) If it has not been burned, use a three-use electricity meter AC voltage file, open the voltage range to 600 volts, place the red and black bars on the AC side of the solid state relay with the line number T , and set the temperature part. The temperature setting value is set to 0 °C. At this time, the indicator of the temperature solid state relay will not light up.

2 ) If the measured voltage value does not change, maintaining the temperature below 10V represents the solid state relay burned and appears short circuited.  

Second, the solution:  

1. If not, please turn the panel over-temperature protector to a position of 150 °C, or use a temperature of 30 °C;  

2. Inform the maintenance department of the purchased manufacturer to replace the circulating motor;  

3 , replace the temperature part of the solid state relay or notify the manufacturer to come to the door for maintenance.  

What should I do if the temperature and humidity controller of the constant temperature and humidity control device shows abnormal temperature? If the temperature and humidity controller displays abnormal temperature during operation, the user should know how to solve it. More technical problems are at Haida Instruments. Welcome to inquire.
