Frequently Asked Questions
How can I check that a spare part is the correct model?
Please send the full order number and a photograph of the label on the original part. We will check that the design matches; similar labelling does not in itself confirm the same wiring or functions.
Can the specified successor model be used without further modifications?
Before replacing a component, it is necessary to compare the wiring, ranges, contacts, behaviour in the event of a fault and settings. The designation of a successor model alone does not confirm that it is a direct replacement.
Can you carry out diagnostics or repairs?
Please send us a description of the fault and the details from the label. We will assess the options for diagnosis and repair, as well as the availability of spare parts. For passive and mechanical components, we will first assess whether repair is worthwhile based on their condition.
