	Providing and assuring safe conditions for personnel is a key parameter required to operate the European Spallation Source (ESS). The ESS will be responsible for developing all of the facility personnel safety related systems. All of these systems will be developed by the Integrated Control Systems Division (ICS) and all will be designed, manufactured, commissioned and operated in accordance with the IEC61508 standard, with regard to functional safety for Electrical/Electronic and Programmable Electronic (E/E/PE) safety related systems. This paper describes the ESS Personnel safety system’s scope, strategy, initial design requirements, and methodology but also provides an update of the system design progress so far.

	Approximately 350 resistive magnets and 350 power supplies (PS) will be installed in the 600 m long linear accelerator (LINAC) at ESS, transporting the proton beam from the source to the target station. In order to protect this equipment from damage (e.g. due to overheating) and to take the appropriate actions required to minimise recovery time, a dedicated magnet powering interlock system is being designed. The magnet powering interlock system will safely switch off a PS upon the detection of an internal magnet or PS failure and inform the beam interlock system to inhibit further beam operation. The different failure modes and related mitigation techniques of magnets and their PS will be presented. Failures of the magnet cooling system can be detected for example by interlocking the opening of a thermo-switch or a flow-switch. To achieve the required level of dependability, an interlock system based on safety PLC technology, distributed safety PLC software programming tools, PROFINET fieldbus networking, and current loops for hardwired interlock signal exchanges, has been prototyped and will be discussed.
