Introduction to the installation method of box-type resistance furnace

1. After opening the package, check whether it is intact and harmless, and whether the accessories are complete. A normal box furnace does not require special equipment, as long as it is placed flat on a flat sky or shelf indoors. The controller should be protected from shock, and the position should not be too close to the box furnace to prevent the external components from being deformed due to overheating.

2. The power supply switch is required to be installed at the power line introduction, and the main power supply is no longer controlled. In order to ensure safe operation, the controller must be firmly grounded.

3. The thermocouple is pulled out of the stove 20-50mm, and the gap between the hole and the thermocouple is filled with asbestos rope. To connect the thermocouple to the control, it is better to use a make-up wire or use an insulated steel core wire, pay attention to the positive and negative electrodes, and do not connect them in reverse.

4. After checking the report and confirming that it is correct, cover the controller case. Adjust the setting needle of the temperature indicator to the required task temperature, and then connect it back to the power supply. Turn on the power switch, the green light on the temperature indicator measuring tool will be on, and the relay will start the task. When the power is turned back, the DC meter will show DC power. With the decrease of the outside temperature of the furnace, the temperature indicating gauge needle also gradually decreases. This scene indicates the task of the system.

5. Before using the box-type electric furnace, move the thermometer indicator to two points. When using the make-up wire and cold-end compensator, move the two points of the machine to the standard temperature point of the cold-end compensator. When the make-up wire is not used, Then the two points of the machine are adjusted to the zero scale position, but the temperature indicated is the time difference between the measuring point and the cold junction of the thermocouple.
