W-IE-NE-R products are designed towards highest reliability and maximum operation time. All products are covered by a 3-year warranty on parts and labor (1 year standard warranty for all special order / non catalog items and radiation-tolerant as well as conduction cooled products). After this warranty period extended service plans can be purchased or paid repair service is available.

Please note that any shipment to the factory has to be paid for by the owner/user. In case of warranty repairs W-IE-NE-R will return the unit free of charge.

The status of a repair can be checked online by providing RMA and serial number.

WIENER Bug Tracker

W-IE-NE-R File Server

Our download section provides documentation, software as well as firmware updates for W-IE-NE-R products.

Discontinued Products

Due to obsolete components and in the case of new developments, existing products can be discontinued without further notice. If a W-IE-NE-R product is not shown in the product section of the current website or latest catalog, it may have been discontinued.

W-IE-NE-R is performing service for discontinued products as long as spare parts are available. Technical information such as manuals, tech notes, software and firmware files may be still available on the W-IE-NE-R file server.

Please contact our service team or the local representative with questions about discontinued products.
