2. Nominal operations

2.1. Instrument switch-on and connection of the warm electronic boxes

- currently done with tcl-script PACS_Switch_On.tcl (maintained by FGB)BR - after execution: PACS is in SAFE mode, the bolometer groups are off, but the temperature sensors are onBR

Note: Autonomy function #6 is enabled to check for the communication between DMC and BOLC

2.2. Cooler recycling (only at HeII temperatures)

- starting out of SAFE mode (groups off, temperature sensors on) BR - CUS script:BR

mode BOLO_cooler_OBS calling the CUS procedure BOLO_cool_recycle:BR
- - no sub-procedures are called, the groups and temperature sensors are not touchedBR - HK_list is set to PHOT_HK and reset to "NON-PRIME" in the endBR - autonomy function 14 is enabled, Duration: 7928 secBR

- ending up in SAFE mode (groups are off, temperature sensors on, HSP heater current at 1.18 mA)BR

Note: At the end of the recycling the autonomy function 14 is enabled. It checks for TEMP_EV, TEMP_FPU1, TEMP_FPU2:

--> HK DEC SOFT is generated if one or more are out of the range [260,320] mK; --> GO SAFE is generated if one or more are above 400 mK

2.3. General Setup for Photometer Operation (after cooler recycling)

- starting out of SAFE mode (groups off, temperature sensors on)BR - CUS script:BR

block PHOT_setup calling the following CUS procedures:BR
- - procedure PHOT_dpu_dmc_setupBR - procedure PHOT_dmc_setupBR
  - - procedure PHOT_fltw_conf BR - procedure CONF_chopper BR - procedure CONF_cs BR
  - procedure PHOT_switchon_groupsBR - procedure PHOT_set_bias (*)BR - procedure PHOT_seq_setupBR - procedure PHOT_change_data_modeBR - procedure PHOT_change_seq_modeBR - procedure PHOT_set_gain(**)BR - procedure PHOT_spu_setupBR

(*) the bias tables to be loaded might change!BR (**) the gain setting can be 'high' or 'low'

- ending up in PHOTOMETRY mode, but SPU processing has not yet startedBR - Note: filter is in position "A", chopper at position "0"BR - calibration sources are set to default values, but need 40-50 min stabilisation time!!!BR

Note: At the end of the PHOT_setup the autonomy function 17 "generate_event_pwr" is enabled. It checks for the HK entries: PC_PWR_ANA_P_#, PC_PWR_ANA_N_# and PC_PWR_DIG_#, with # = [1,2,3,4,5,6,7]

2.4. Operation of the bolometers (starting out of PHOTOMETRY mode)

2.4.1. start/stop of bolometer data flow

CUS scripts:BR
- block PHOT_spu_setup_OBS calling procedure PHOT_spu_setup ---> bolometer data flow running BR block PHOT_spu_reset_OBS calling procedure PHOT_spu_reset ---> bolometer data flow stopped BR

2.4.2. Change of the bolometer data/sequence mode and gain

CUS scripts:BR
- - procedure PHOT_change_data_modeBR - procedure PHOT_change_seq_modeBR - procedure PHOT_set_gainBR - or via MSTK with individual commands

2.4.3. Take data with manual chopper & filter movements

CUS scripts:BR
- block PHOT_spu_setup_OBS calling procedure PHOT_spu_setup ---> bolometer data flow runningBR
  - - block PHOT_fltw_move_OBS calling procedure PHOT_fltw_moveBR - command Pacs_DMC_MOVE_CHOP_ABSBR - command Pacs_DMC_MOVE_CHOP_RELBR
  block PHOT_spu_reset_OBS calling procedure PHOT_spu_reset ---> bolometer data flow stoppedBR

2.4.4. Take data with pre-defined OBCPs

  - - block OBCP_chopped_photometry_OBSBR - block OBCP_phot_chopper_scan_OBSBR - block OBCP_fixed_fixed_photo_OBSBR
  block PHOT_spu_reset_OBS calling procedure PHOT_spu_reset ---> bolometer data flow stopped BR or
  block PHOT_spu_setup_OBS calling procedure PHOT_spu_setup ---> bolometer data flow running BR
  - - block PHOT_all_aots_OBSBR calling the following procedures:BR
    - - procedure OBCP_chopped_photometryBR - procedure OBCP_chopped_photometry_ditherBR - procedure OBCP_phot_freezeframeBR - procedure OBCP_phot_cal_IBR - procedure OBCP_phot_cal_IIBR - procedure OBCP_phot_cal_IIIBR - procedure OBCP_phot_staringBR - procedure OBCP_phot_chopper_scanBR - procedure OBCP_fixed_fixed_photoBR
  block PHOT_spu_reset_OBS calling procedure PHOT_spu_reset ---> bolometer data flow stopped BR

Note: all OBCPs can be started with default parameters via the generic tcl-script; the key-OBCPs can also be started with freely selectable parameters via specific tcl-scripts

2.4.5. Execute AOT observations

CUS scripts (to be finalised):BR
- PHOT_AOTBR
  - - PacsPhotDefaults BR - PacsPhotEstimatorOBCPnBR

2.5. Reset after photometer operation

- PACS is in PHOTOMETRY or any other modeBR - execute mode PHOT_switchoff_groups_OBS calling procedure PHOT_switchoff_groupsBR
- (this will reset the biases sequentially, disable the AF 17, and switch off the groups)BR
- going into SAFE modeBR
- (this will disable the AF 14 for the FPU temperature checks)BR
- after execution: PACS is in SAFE modeBR

2.6. Instrument switch-off

- currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB)BR
- (this will disable the AF 6 for the DMC-BOLC communication check)BR
- after execution: PACS is switched offBR

3. NOTES

- the SFT tests are described in PACS-ME-TP-007BR - some specific photometer tests, like the thermal behaviour measurements, start directly out of SAFE mode, while most of the tests will be executed after the PHOT_setup - the above mentioned CUS scripts (with a few exceptions) have been tested and are available in the CUS database and from the CVS libraryBR - the AOT related CUS-scripts are still under testing
