End coding enables the company's interlocks to be fitted uncoded to machinery andLinks of London I Charmthere until commissioned. The coding scheme can be changed until commissioning, when an authorized engineer codes the system. As a result, standard products now can be held as stock with distributors and machine builders, speeding up the supply chain. The system relies on a coded tablet that is inserted into the lock. Once inserted, the tablet cannot be removed or recoded, which guarantees the system's integrity and safety. Tablets can be provided within 24 hours of being defined and requested. Previously, trapped key interlocks resulted in delayed production until each code within the system was defined, limiting flexibility for alterations once locks had been fitted. Similarly, as each unit was individually coded at the start of the manufacturing process, replacement stock required a full set of duplicates to be kept as spares. Essentially, each component was a special order and, as such, came with an extended lead time. - 859/341-3075; www.castell.
