On-Board W Module Programming and Operation CTI-CRYOGENICS HELIX TECHNOLOGY CORPORATION Appendix C - RS-232 REGEN Responses Introduction Appendix C describes the On-Board pump REGEN responses which are requested by host computer O status command. The regeneration responses inform the host computer of the regeneration cycle status of the On-Board pump. NOTE: In some cases there are several responses which mean the same thing. Regeneration Response Description Refer to Table C-1 for a complete description of the regeneration responses. P/N 8040365 C-1
Appendix C - RS-232 REGEN Responses CTI-CRYOGENICS HELIX TECHNOLOGY CORPORATION Table C-1: RS-232 REGEN Responses and Descriptions REGEN Response A D Cryopump OFF Description WARM-UP - During warm-up you may also want to display the actual 1st stage temperature and the temperature it is attempting to reach. The reduced temperature of 285K represents a failure of the pump to reach 310K in 60 minutes. Example: WARM-UP 272K/285K The 285 is fixed and the 272 is the response from the command K. E WARM-UP - During warm-up you may also want to display the actual 1st stage temperature and the temperature it is attempting to reach. Example: WARM-UP 234K/310K The 310K is fixed and the 234 is the response from the command K. H EXTENDED PURGE An H response means that the pump has reached its warm-up temperature and the purge is being extended for some amount of time. The time is determined when the regeneration parameters are programmed. The time remaining in minutes is command k. Example: EXTENDED PURGE 12 MIN C-2 P/N 8040365
