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.
Is this a separate basic safety relay?
This order number refers to an output extension. When designing or replacing the system, the base unit and the connection method must also be verified.
Is it possible to interchange the screw and spring versions?
Before replacement, check the full designation, power supply, dimensions, wiring connections and the interconnection of the safety assembly.
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.
