Frequently asked questions
How can I verify the correct replacement?
Send the full order number and a photo of the original relay nameplate. We will check the version; a similar designation alone does not confirm identical power supply, wiring or functions.
Can any temperature sensor be connected?
No. The sensor type must match the supported types in the technical table. During commissioning, check its settings, wiring and measuring range.
Do the settings need to be transferred when replacing the relay?
Yes. Record the existing settings before replacement. After installation, check the limits, timing and response of the downstream control system. If changing the relay type, also check the wiring diagram and application requirements.
Can you arrange diagnosis or repair?
Send a fault description and the nameplate details. We will check diagnostic and repair options and spare-part availability. The specific procedure will depend on the condition of the device.
