With over ten years of experience in UNIS Group’s Specials department, Dennis Koller is a master at solving complex electronic issues. With the precision of a detective and the enthusiasm of a passionate hobbyist, he tackles challenges daily. The Specials department comprises a team of technicians specialising in repairing a wide range of electronics, from customer-specific systems to rare and modified devices. “There are a few people in the department who are very enthusiastic and skilled with electronics, and I’m one of them,” Dennis says with a smile.
From hobby to professional career For Dennis, electronics has always been a hobby. He chose to study at the Technical College and gainedseveral years of work experience at other companies before joining UNIS Group in 2013 in the Specials department, where he plays a key role. “We often deal with unique and undocumented electronic devices that we need to analyse and repair,” says Dennis. “Sometimes they’re everyday devices like PLCs and laser-guided systems, but often they’re obscure and outdated machines from manufacturers that no longer exist, with little information available.” Dennis’s approach is systematic and patient: he measures, tests, and puzzles until he finds and fixes the faults.
Complicated cases Within UNIS Group, there is a clear division of tasks,mwith the team leader coordinating repairs and distributing them based on urgency and expertise. Dennis is often called in for more complicated cases, especially those involving electronics that require his specific knowledge. “Some repairs are really challenging. I sometimes see devices I’ve never seen before, whose existence I wasn’t even aware of. Try repairing those! Not all devices can be repaired, especially when dealing with unsupported machines and devices. If programmed components are faulty, we can’t always retrieve the program. But we don’t give up easily. We always aim for repair rather than disposal.”
Solving puzzels Dennis enjoys the most puzzling out and identifying the fault in the device. “When I hold a circuit board in my hands, I immediately feel the urge to investigate where the fault is.” To resolve the fault, Dennis not only examines the device itself but also tries to obtain additional information by searching online and asking the customer to create a testing possibility. “Unfortunately, we often get very little information. I’ve even heard a customer say, ‘We’re paying you, so figure it out yourself.’ This makes it all the more satisfying for Dennis when he successfully repairs a device. His motivation comes from knowing that each resolved issue contributes to customer satisfaction and the company’s success.
