General knowledge of secondary processor maintenance is a daily business skill that must be understood and learned by manufacturers using secondary processors.

Nowadays, many of the equipment are secondary processing machine, secondary processing machine equipment maintenance common sense is becoming more and more popular. And equipment above the touch screen or text display, general equipment, common failures will be displayed on it. So relatively speaking, the maintenance of the secondary processing machine is relatively easy, can quickly determine the cause of the failure.

The following are general maintenance ideas for secondary processor maintenance common sense：

1、See if there is an alarm message on the screen or text display of the secondary processor, if so, find the cause according to the message；

2、Be familiar with the action process of the secondary processing machine, step by step conditions. For example, the equipment alarm "not in the origin", then we need to know where the origin of the equipment, to see if the equipment is really not in the origin. Then the next step to find the cause；

3、Recognize the various detection sensors. General secondary processing machines rely on detection signals to send corresponding action instructions or prompt the completion of the current action or not. Therefore, regardless of whether there is an alarm or not, once the equipment does not move, first check the detection switches in each position.；

4、When it is confirmed that there is no problem with the detection signal, finally go to check the actuator or control device。
