4. Last week 0n 03/08/2017
‘About the coldbox, the 6 PT100 will be installed Monday afternoon, along the red bar’

5. Installation of the RTD sensors inside the Coldbox bar on 08/08/2019

6. Detail of the RTD connection on top of the Coldbox

7. Coldbox DCS
The main features are:
Two AC/DC power supply: one 24 VDC for general DCS controller, fan on/off, pressure sensor power supply and a 12VDC (adjustable) power supply for the heaters. Both AC/DC power supplies are powered by 220Vac detector side.
DCS controller : Siemens S (CPU1511) Supplier link
The PT100 either for the coldbox either for heaters are read by the analogue input Siemens with a accuracy +/- 0.1C
The heater ON/OFF power and fan ON/OFF are controlled by a digital output connected to an solid state isolated relay, Phoenix Contact manufacturer link: relay
Each individual heater or fan heater are individually fuse protected.
The temperature regulation is programmed inside the DCS controller, to be defined but we have already a default sequence.
The controller is connected to PC through Ethernet with the CERN WINCC supervisor software and with CERN UNICOS framework installed
On detector ground
