ESS, Target Division, Target Controls and Safety group is responsible for the design and construction of the TSS. TSS stops Proton production if vital process conditions measured at the Target Station, are outside the set boundaries with the potential of causing (radiation) injury to third parties (public outside ESS fences). The TSS is a 3-channel fail-safe safety system consisting of independent sensors, a two redundant train system based on relay and safety PLC technique and independent ways of stopping the proton beam accelerator. TSS will continuously monitor safety parameters in the target He cooling, wheel, and monolith atmosphere systems, evaluate their conditions, and turn off the proton beam if necessary. After passing several stages of off-site test, the TSS cabinets are now installed on site and successfully passed internal integration. In this paper we will explain features we fit into the system to ease emergency repairs, system modification and system safety verification and in general maintainability of the system.
