Four Instructions for Use
1. Wiring method (this product should be wired according to the following diagram during operation)

2. Temperature measurement
K1 is the temperature measurement and setting function selection button. Selecting K1 to be in temperature measurement mode will display the measured temperature value.
3. Set upper and lower limit alarm temperatures
a、 Switch K1 to the setting state, which is now in the setting function state, and the panel displays the set temperature value.
b. K2 is the selection button for setting the upper and lower limit alarm temperatures. Set upper limit alarm temperature: Select K2 to be in the upper limit temperature state and adjust the corresponding upper limit potentiometer to make the displayed value equal to the upper limit alarm temperature value that needs to be set. Set lower limit alarm temperature: Select K2 to be in the lower limit temperature state and adjust the corresponding lower limit potentiometer to make the displayed value equal to the lower limit alarm temperature value that needs to be set.
C、 After setting the upper and lower limit alarm temperatures, switch K1 back to temperature measurement mode.
4. System working mode
When the transmitter is working normally, if the temperature is between the upper and lower limit alarm temperatures, the output relay will not operate; If the temperature rises above the upper limit alarm temperature, the upper limit alarm relay will activate, the normally open contact will close, and the upper limit alarm indicator light will turn on; If the temperature drops below the lower limit alarm temperature, the lower limit alarm relay will activate, the normally open contact will close, and the lower limit alarm indicator light will turn on.
5、 Installation method
YWD-KT has two installation methods: guide rail and screw installation. The bottom view is as follows

6、 Ordering Notice
When signing the contract, please provide detailed specifications and parameters of the required products, and fill in the code in the following format. For special needs, please use
Text description.

Example: Temperature switch transmitter
YWD-KT-R1-T1-J1-P1
R1: Input resistance PT100]
T2: Temperature measurement range -10-100 ℃
J1: Number of output channels, one contact point
P1:AC85～265V

7、 Precautions
1. The upper limit alarm temperature must be set higher than the lower limit alarm temperature.
After completing the alarm temperature setting, the K1 button should be switched back to the temperature measurement state.
When the measured temperature exceeds the limit, this product will not display.
4. The usage environment should be free of conductive dust, corrosive and insulating gases, and the poster height should be less than 2500 meters
