Current system and migration proposal to crate/online version Currently (offline) 8 locations (P 1, P 2, P 5, P 8) with: - 4 x 2 heaters (EH 894 (1 & 2)). - 4 x 2 thermocouples (TT 89 A/B). - 4 x 2 temp. sensors on flanges (TT 894 A/B). CP L P 1 disc , P 2 P 5 to ussio , P 8 c stay n: Proposal (online) an Proposal benefits include: 4 locations (P 1, P 5) no change due to Hi-Lumi LS 3. be as is • Convert to standard maintenance. du up 4 locations (P 2, P 8) to change with: e to • Access to all data/regulations. - 2 EH 500 W cards (2 channels each with (1 & 2) in parallel). gra d e e - Includes 1 thermocouple per flange (1 spare). nd • Better situational awareness. d. of • Remote setpoint controls, On/Off. - 2 TT cards (2 channels each + spare per channel). DF - PLC integration. BX life Required work at L Total (P 2, P 8): S 3 8 EH 500 W cards: (~ 8 * 600 CHF = 4. 8 k. CHF). 8 TT cards (stock [8*350 = 2. 8 k. CHF). 32 DSub 9 TT signals. (32 * 5 = 0. 16 k. CHF). 16 or 32 lemo 4 connectors (0. 16 or 0. 32 k. CHF). 1 to 1. 5 weeks work in-situ 1 FSU. Total: ~10 k. CHF + Production will include 16 EH 500 W cards for LHC + projects. (~ 16 * 600 CHF = ~ 9. 6 k. CHF) : Has to be done 20/12/2021 Searching BC for ~10 k. CHF (97555? ) + 10 k. CHF on material. CPL decision to use the 97555 for all orders 20 k. CHF. Document reference 5
