proto. DUNE Single Phase DCS PLC - Safety System - Photon Detector & LED’s

proto. DUNE Single Phase DCS PLC - Safety System - Photon Detector & LED’s Interlock Are executed in the main DCS PLC, Siemens S 7 -1500 3 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE LV PL 506 Interlock The Cold Electronics

proto. DUNE Single Phase DCS – CE LV PL 506 Interlock The Cold Electronics Low Voltage PL 506 interlock is performed by the DCS-PLC and a “fail safe” control electrical circuit 4 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE&Low Voltage Control The internal data of the

proto. DUNE Single Phase DCS – CE&Low Voltage Control The internal data of the WIBs is transmitted to DCS with the WINCC–DIM protocol. We did not apply action/interlock But can be easily implemented 5 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE fan control Specifications - Each APA/Cold Electronic

proto. DUNE Single Phase DCS – CE fan control Specifications - Each APA/Cold Electronic flange has 4 cooling fans. - According to J. Fried, if the fans stop blowing air while electronics on the PTC board reaches 50 °C. Important to monitor the status The installed fans have an error signal but is not Fail-Safe. With the Pull-Up resistor we have 0 V when there is an error in the fan. Cold Electronic Flange with 4 fans 6 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE Fan Connection The 4 fans installed in the Cold electronic flange are cabled according this specifications drawing. Connected in a single Sub-25 Connector 7 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE Fan Control We have prepared 2 crates,

proto. DUNE Single Phase DCS – CE Fan Control We have prepared 2 crates, 3 U size, installed in the Rack 5 1 crate for controlling the 3 APA’s Ra. S Side 1 crate for controlling the 3 APA’s Da. S Side Both crates are powered from main 24 V DCS Fan Control Crate Da. S Side Fan Control Crate Ra. S Side 8 1/23/2022 X. Pons

proto. DUNE Single Phase DCS – CE Fan Control Circuit It consists basically in

proto. DUNE Single Phase DCS – CE Fan Control Circuit It consists basically in an electromechanical relay operated from DCS which allows the ON/OFF operation. The 24 VDC after the relay is connected directly to the main DCS PLC, for PL 506 Interlock evaluation. This is how are performed the control and the PL 506 interlock until now. 9 1/23/2022 X. Pons
