A manufacturing company in Harju County had a problem with a cardboard and plastic film baler used as a waste press, which is part of its daily production process. It started when the machine’s cable got caught between the wheels, causing the machine to stop working. The company’s in-house electrician tried to fix the fault, but after the repair he carried out, smoke started coming from the control panel and the machine no longer responded to anything.
In this situation, the company turned to Maintest Grupp OÜ for help. Our technicians began thorough troubleshooting and found that the cables had been connected incorrectly during the earlier repair. The cables were reconnected correctly, but the machine still did not start.
Since correcting the connections alone did not solve the problem, we carried out additional troubleshooting with measurements to identify the exact cause of the fault. The measurements showed that the bridge rectifier and a capacitor had been damaged. These components were replaced with new ones, after which the machine was tested.
All of the work, including troubleshooting, correcting the connections, additional diagnostics and replacing the components, was completed within one working day. As a result, the client got back a fully operational waste press, which is once again in use in the company’s production process.
This example clearly illustrates why it is important for equipment repairs to be carried out by experienced specialists: a repair done incorrectly can cause a bigger fault than the original problem. Maintest Grupp OÜ technicians identify the true cause of a fault through systematic troubleshooting and measurements, rather than settling for a superficial fix. Thanks to this, we were able to help the client quickly and efficiently, avoiding prolonged equipment downtime.
