This is a maritime radar system designed for use on vessels requiring X-Band / S-Band coverage according to IMO SOLAS regulations. It is manufactured by Hyundai Welding Co., Ltd. (Pohang) under the model designation SC-ES5 / S-ESF. This radar system has received DNV approval. While designed for reliable performance, some common failures can occur, including magnetron end-of-life after 5,000-8,000 operational hours (for magnetron models), antenna rotation motor bearing damage after 30,000+ hours, display backlight failure, heading marker alignment drift, and waveguide moisture intrusion due to disrupted pressure regulation. To ensure optimal operation, Hyundai Welding Co., Ltd. recommends keeping a spare magnetron on board for magnetron models, with a lead time of 1-3 weeks for delivery. Regular maintenance is crucial, including magnetron replacement every 5,000-8,000 hours, annual antenna bearing lubrication, weekly performance monitor testing (meeting IMO requirements), and an annual inspection.
