The ESS Superconducting LINAC and the ESS Cryomodule Test Stand, will require major cryogenic services in order to be supplied with liquid nitrogen and helium. Since the use of cryogenic fluids can be associated with Oxygen Depletion Hazard (ODH), the ESS Protection and Safety Systems group will install an ODH Detection System which is a PLC-based alarm system. This system will monitor real time Oxygen concentration levels in designated areas, with the aim to alarm personnel if the oxygen level is detected below certain thresholds. This paper gives an overview about the requirements, system architecture, hardware and software of the ODH Detection System in ESS Accelerator buildings PB - JACoW CP - Geneva, Switzerland SP - 666 EP - 669 KW - ion KW - PLC KW - cryogenics KW - controls KW - ion-source DA - 2018/01 PY - 2018 SN - 978-3-95450-193-9 DO - 10.18429/JACoW-ICALEPCS2017-TUPHA106 UR - http://jacow.org/icalepcs2017/papers/tupha106.pdf ER -
