Electrical Troubleshooting Principles of Pull-ups Production Line 

For pull-ups machine maintenance management, common electrical faults need to be analysed and the cause of the fault initially determined by specialist technicians after the fault has occurred, based on the form of performance. In particular, the maintenance technician is asked by the operator to determine the entire fault process and to analyse the data recorded in the operating status of the pull-ups production line to determine the root cause of the fault. On this basis, combined with previous management experience, a reasonable maintenance programme is developed, managed and maintained in accordance with professional specifications, the scope of influence of the fault is controlled and the fault is resolved in the shortest possible time.

1. Pull-ups production line troubleshooting sequence

(1) Check first and then energise
After determining the electrical fault of the pull-ups machine, it is necessary to prepare a corresponding overhaul plan and carry out comprehensive observation, testing and analysis of the pull-ups production line without powering it up to determine the nature of the fault. If the fault is of a vicious and destructive nature, it needs to be lifted promptly. For non-malignant destructive faults, e.g. servo cannot be energised; simple analysis to accurately determine the fault location.
(2) Software first, then hardware
After the system software failure, it will affect the normal operation of the pull-ups production line, once the software parameters are lost, it will affect the next operation of the software. Therefore, when repairing faults, software tests need to be carried out first to make sure that there are no errors before repairing hardware faults.
(3) External first and then internal
After running a fault, the maintenance personnel need to make a preliminary estimate of the fault part according to the performance status of the equipment and overhaul the faulty part. After determining that the parts are fault-free, check whether the hydraulic components are normal, such as hydraulic components and electrical contact parts are loose, common electrical control cabinet sockets, printed circuit board sockets, etc., often due to operating vibration, temperature, humidity, dust and other factors, affecting the signal transmission effect, eventually leading to operational failure.
(4) Mechanical first, then electrical
The pull-ups production line system is relatively complex, involves more specialised technology and has a high degree of automation. For this reason, when carrying out troubleshooting, it should be carried out in the order of mechanical first and then electrical. In terms of operational status, many electrical faults are caused by faults in the system operation, such as abnormal trip switch operation. Moreover, system faults are easier to detect, whereas electrical system faults require specialist equipment maintenance.

2. Pull-ups production line troubleshooting methods

First, the intuitive method. That is, maintenance technicians use past experience to analyse the light, smell and sound of the pull-ups production line, check the various parts, determine whether there are abnormal effects such as burning and damage, and effectively narrow the scope of the fault. Secondly, the exchange method. After determining the approximate location of the fault, if the information on external conditions is identical, maintenance can be carried out by means of replacement, thus effectively shortening the fault maintenance time.

pull-ups production line electrical faults are more common in production activities, in order to reduce the scope of the impact of faults, measures need to be taken to diagnose various faults in a timely manner, determine the causes, develop a reasonable maintenance plan, select the most appropriate maintenance methods and processing techniques in conjunction with the actual situation, arrange for professional staff to carry out fault maintenance, strive to eliminate the threat of faults in the shortest possible time, and strive to continuously improve operational stability and safety and promote the further development of the enterprise economy.
