Quick Parameter [1]: Temperature range can be set from 50 to 500°C/122 to 932°F.
Quick Parameter [2]: Temperature range can be set from 50 to 500°C/122 to 932°F, and operating time can be set from 000 to 900 seconds.
Quick Parameter [3]:
For ST-7500, Temperature 1 range is 50 to 300°C/122 to 572°F, Temperature 2 range is 300 to 500°C/572 to 932°F.
For ST-7800, the Temperature 1 range is 50 to 200°C/122 to 392°F, the Temperature 2 range is 200 to 350°C/392 to 662°F, and the operating time can be set from 000 to 900 seconds.
(As shown in the figure) The main interface displays Quick Temperature [3]. The machine will first heat up to 300°C (Temperature 1) according to the set quick temperature, and start the operating time countdown. After the countdown ends, the machine will continue to heat up to 400°C (Temperature 2) and begin another operating time countdown. After the countdown ends, the machine will automatically stop heating. (as shown)

Quick Parameter Groups Reset:

Under the Quick Parameter settings, select the “Reset” function, and enter the machine password to reset the quick parameters.

Factory Reset:

To restore factory settings, a password must be entered. After entering the correct password, the machine will automatically restart and restore the factory settings.

Use the communication cable as shown in the diagram to connect this product’s RS485 interface to the computer’s USB interface.
On the computer side, use upper computer software to control the preheating platform machine with commands.
Please visit the “www.atten.com.cn” official website or contact the manufacturer to download the corresponding driver, DEMO software, and communication protocol documentation.

Instructions for K-Type Thermocouple:

As shown in the diagram, insert the K-type thermocouple into the corresponding interface of the preheating platform host. (Note: To avoid damaging the components and the host, ensure that the positive and negative terminals of the K-type thermocouple correspond to the positive and negative terminals on the machine’s panel).
On the main interface of the preheating platform host, the “External Test Temperature” will display the actual temperature data measured by the thermocouple, making it convenient for users to test the actual temperature of the heating product.

Note : The positive and negative poles of the K-type thermocouple must be inserted to correspond with the machine’s panel’s positive and negative poles.
