1 - Due to the urgent request for membrane signal monitoring, the final DCS controller has been installed in the rack 2 With its supervisor application. The system includes the absolute and differential pressure signal of the inner/outer side of the membrane to observe its status. Also we have included the environmental signals: Ambient temperature Ambient humidity Atmospheric pressure Awaiting the multiplexer card to read the membrane temperatures. The system is working and archiving data. 2

Main DCS controller Rack Coldbox Rack Main DCS controller installed, PLC type (Programmable Logic Controller) SIEMENS S 7 -1515. Standard and CERN controls supported Easily integrated into SC WINCC program More information can be found https: //www. siemens. com/global/en/home/products/automation/systems/industrial/plc/simatic-s 7 -1500. html 3

2 - COLDBOX. Slow Control almost finished with the integration of the Photon Detectors MPOD Power Distribution Supervisor PC SC Controller Siemens S 7 1500 Field Interface Cold Electronics PL 506 PS Cold Electronics MPOD PS Photon Detector MPOD PS • • Working on the final SC WINCC supervisor Wiener MPOD and PL 506 integrated in the WINCC program Temperature gradient monitor repaired All cables LV, HV, Temp, Optical already installed • Tests done with the Cold Electronics: • 48 VCC from PL 506 ok, control from SC • Fans OK • Heaters OK • Interlock of the PL 506 PS linked to the fans ON. • During the tests with the Cold electronic team we found a surprise with 10 Volts power supply for the heaters. This PS, switching power supply, generated quite a lot of noise in the CE data taking. For the meanwhile it has been disconnected and it will be replaced by another type. • Also a test has to be repeated with the fans when they are ON they generated a noise a 50 k. Hz band 4

3 - COLDBOX CRYOGENICS. In addition CERN/DT has been requested to produce the hardware/software for the cryogenic control system Also a control system based on Siemens 1500 controller that executes the process Connected to the WINCC application as supervisor program 6
