Attached are the MDI recovery procedures from the Leonids safing. I have run these control files on the simulator, and they have functioned correctly to the limits of the simulator (there being no door mechanisms on the simulator). The control files listed below can be found in the /mdisw/cfl/flight/src directory on mdicmd and mdisas. They should be checkpointed and compiled, and the safing instance updated. Regards, Rock ************************************************************** Procedures for Recovery of the MDI Instrument The MDI recovery procedures are similar to the final steps of the recent MDI power up, except that they will all be performed via NRT commanding. It is expected that the instrument recovery activities upto opening the front door will take less than two hours. After the door is opened, four hours of VC2 telemetry are required to perform the front window focus tests. The following sequence of MDI control file procedures will power up the CCD camera, Optics Package mechanisms and the Image Stabilization System. Record the MDI bus A current exec q_fl_cmon_v02 Verify that the CCD camera is powered on. exec q_fl_mchson_v02 Verify that the shutter, MTM, CAL and PAW mechanisms are powered on. exec q_fl_lton_v01 Verify that ISS is powered on. Record the MDI bus A current exec q_fl_htr_config_v01 Adjust heater setpoint to "63" Verify that hopspt is set to 63, and heaters 2 & 3 are powered off. After the MDI subsystems are verified to be in an acceptable state, the standard observing sequence will be started while the front door is still closed. exec q_reset_v05 exec q_runstr_v28 A focus test sequence will be run while the front door is opening and the front window temperature is changing. exec q_seq_options_v09 Set the campaign index to cam_focus_2 Verify that high rate data is being received with dpc: 404fc001 fd_hr_focus The procedure to open the front door is: exec q_fl_fd_open_v01 The door switch status is checked before and after issuing the door open command. If a check fails, the procedure will halt. The procedure should not be restarted without clearly understanding the check failure. Verify that the front door is open and door power is off. About 1 to 2 hours after the front door is open and the initial front window temperature change is slowing down, the ISS error signals can be nulled and the loop locked. exec alignit_v16 Select "NULL/LOCK ISS" Continue the focus_2 test until the end of contact (can be in VC3). Set the chain list for cam_focus30 plus the campaign of the day (one possibility is mag_movies2).
