All three must fit the same RCDE model. If one value is above the model limit, move to a larger RCDE before choosing Standard, T1, T2 or T3.<\/p><\/details>\r\n<details><summary>Is RCDE-8 suitable for an 800 mm belt?<\/summary><p>RCDE-8 is the starting size for an 800 mm belt only when the other limits also fit. Its listed material-depth limit is 200 mm and its rated suspension-height limit is 250 mm. At 230 mm material depth, do not use RCDE-8; check RCDE-10 first.<\/p><\/details>\r\n<details><summary>When should I use T1, T2 or T3?<\/summary><p>After the RCDE size fits, Corvelan starts with T1 for one difficult condition, T2 for two difficult conditions, and T3 for three or more difficult conditions or high damage risk. If the model size itself is too small, move to a larger RCDE first.<\/p><\/details>\r\n<details><summary>When should I choose self-cleaning instead of manual-clean?<\/summary><p>Check self-cleaning first if the magnet needs cleaning more than once per shift, the conveyor cannot stop, the magnet cannot be reached safely, or captured iron must discharge automatically.<\/p><\/details>\r\n<details><summary>Where should the magnet be installed?<\/summary><p>Use above-belt installation as the starting position for many moderate-depth retrofits with good overhead space. Check the discharge\/head-end position first when material is deep or important iron may be buried low in the burden.<\/p><\/details>\r\n<details><summary>Does higher Gauss always mean better iron removal?<\/summary><p>No. Gauss or mT describes magnetic-field strength at a defined point. Capture also depends on working distance, material depth, belt speed, iron size, iron position and installation geometry.<\/p><\/details>\r\n<details><summary>When is a magnetic-field test required?<\/summary><p>If the quotation or order includes a specific mT or Gauss value, define the instrument, measurement point, exact distance, probe direction, energized condition and pass value before shipment inspection.<\/p><\/details>\r\n<details><summary>When should I use a real tramp-iron capture test?<\/summary><p>Use a capture test for critical crusher or mill protection, T3 duty, smaller buried iron, high working distance, or whenever the order requires proof that a defined steel object is captured under defined conveyor conditions.<\/p><\/details>\r\n<details><summary>What should I send Corvelan for selection?<\/summary><p>Send the material, largest damaging iron, smallest iron that must be captured, belt width, belt speed, maximum material depth, proposed suspension height and the downstream equipment being protected. A conveyor photo or layout is also useful.<\/p><\/details>\r\n<details><summary>What should I receive before production and shipment?<\/summary><p>Before production, the final order identifies the RCDE configuration, approved GA, connections and inspection method. Before shipment, Corvelan completes the agreed checks and document set, including magnetic-field or capture-test records when those tests are part of the order.<\/p><\/details>\r\n<\/div><\/div><\/section>\r\n<section class=\"cl-final\"><div class=\"cl-inner\"><div class=\"cl-grid-2\">\r\n<div><div class=\"cl-eyebrow\" style=\"color:#8ed5df\">RCDE Selection<\/div><h2>What Information Should You Send?<\/h2><p>You do not need a finished specification to start.
