Experimental freeze dryer control system (electrical system) fault repair
1. The experimental freeze dryer control system does not light up.
(1) The touch screen is damaged and a new touch screen display is replaced.
(2) The touch screen power supply failure, check whether the power supply line of the touch screen is normal, and whether the power supply voltage is normal.
2, experimental freeze dryer control system touch screen can not operate
(1) When the touch screen is completely inoperable, the internal sensing film of the touch screen may be damaged. It is necessary to replace the new touch screen or return the touch screen to the manufacturer for repair. (2) When the touch screen operation is not sensitive, it is only necessary to enter the touch sensitivity of the system calibration touch screen to solve the fault.
3, experimental freeze dryer control system touch screen and PLC communication failure
(1) If the data communication line is faulty, replace it with a new data communication line.
(2) The touch screen communication excuse is damaged or the PLC communication excuse is damaged.
(3) The touch screen program is damaged or the PLC program is damaged, or the communication protocol between the touch screen and the PLC is not uniform.
4. Other failures of the experimental freeze dryer control system
If there is a problem with any other part of the electrical system, replace the damaged parts after inspection. If the electrical connection line is loose, fix the loose joint.
