HET Opening Checklist

Ops Checklist Details version 2004.5 Revised 01Sept.2004

Enclosure Thermal Control (afternoon ops )

1. Log into jove as guider

2. (3-3) open WXGui's & Netscape, check weather and AccuWeather swag

a) Monitor the dome T vs. outside T and try keep them close by typing “ahu temp #” in the smoke xterm on monitor 1.

i. By keeping the temperature of the dome and truss approximately the same as the outside T, the initial stack of the night is much easier and has a better chance of lasting longer if temperatures are relatively stable when we open and are ready to stack.

b) The following websites are helpful in determining whether to open:

i. On Netscape, we have bookmarked on the toolbar:

1. “Current APO weather information”

2. “NWS Doppler Radar…Midland/Odessa, TX”

3. “HET Observing Support Page”

3. update temperature in dome on smoke window to 2C less than SWAG

System Checkout (evening Ops)

1. Check that chiller is on. If it is off, open smoke window and type jcon. This will bring chiller

online

2. large air compressor: oil level, power on, test panel lights, start, check oil flow

a) rotate the red knob counter clockwise in order to be able to start the compressor

b) test panel lights on operating panel

c) push and hold compressor button until compressor has fired up completely

d) on top of the large metal filter case to the left of the operating panel, check to see if oil is flowing by looking into the sight glass of the pipe (flashlight may be needed).

Generally a small oil flow is observed.

3. dryer: open large dryer valve, power on dryer

e) once the gauge on the compressor operating panel has reached 750kpa, slowly raise the yellow valve handle (dryer valve)

f) once dryer valve is completely in the “open” position (perpendicular to the floor), push the black button on the dryer control panel to actuate dryer cycle.

Warning: A sudden blow down will occur. There will be a loud rush of air

blowing by your feet. Protect eyes and ears if you are standing close to

the dryer.

4. glycol startup: start, gauge at 8 GPM

a) in the control room, go to the electrical room; just inside the door to your right, there is a box labeled “GPD/515”. Push the blue button that says “Run”.

b) After a few minutes, at the bottom of the control room cabinet, the little red light should go out next to the green label “Loss of Air and/or Glycol”. This occurs when the gauge right next to it with a yellow label “glycol flow gpm” reaches ~5

The standard flow rate should stay at 8gpm. This ensures glycol flow to the

tracker.

5. inspect interior: be on the lookout for any glycol drops due to a leak, sweep pier

6. inspect exterior: glycol pump and tank, ahu's, chillers

7. Open smoke

a) Open smoke xterm from the pulldown menu and type “startwork” at prompt.

d) After a minute, on SAMS GUI, click Operate and another GUI will appear.

e) Ensure that no errors appear on the “SAMS Server” GUI in the boxed sections titled “Errors Encountered” and “Bad Sensors”. See the detailed Ops Eng Manual for what to do in the case that errors are encounted (which usually happens after a few minutes).

9. (2-1) open Dome GUI, open roof vents and home dome on GUI

a) from desktop menu, click Mars-Hefi>Start Mars-Hefi System

i. on the GUI labeled “MARS GUI”, about ¾ of the way down, click the ON button next to the word Wavescope.

ii. Make note of the axis positions (x,y,f) and then click the green button next to Home, labeled “ALL”. Once the axes are homed, put the positions back to where they were.

b) From desktop menu, click Mars-Hefi>HEFI Light Source

c) From desktop menu,click Mars-Hefi>HEFI Interface

i. On this GUI, type “m” to ensure mirror is inserting and retracting fully. After you’ve typed “m” and hit Enter, there should be a message saying “Mirror Status: inserted (or retracted)”.

14. open baffle xterm, check translation slide

a) log into a baffle xterm as guider

b) at baffle% prompt type ‘trans z’

c) type ‘trans @#’ where the # is 1,2,3, or 4, and hit Enter

d) type trans z again and verify that the current slot position is at the correct # that you’ve just typed in.

e) repeat steps c and d while moving to a different position.

f) Important: Leave translation slide in position 4 for daysky observations.

15. reset SPS system

a) To view SPS GUI on the Frijole monitor, press button #3 on the KVM Switches panel on the cabinet underneath the large monitor.

b) if the SPS program is running, close it by selecting File->Exit.

a) In the cabinet that is beneath the suspended monitor, there is a box with the label “Calibration Screen Switch” and switch it from Out to In and then back to Out, listening for the movement of the screen. A visual confirmation of the calscreen moving in and out is possible by viewing channel 1 on the large

monitor.

b) Important: Leave calscreen out for day sky observations

17. open FIF/PMT GUI, home HRS/MOS probes, then set HRS probe 242,000 and watch its motion on channel 3 of TV; when done, ensure lamps/camera are off (**while moving, click continue, not abort!)

a) On KVM Switch #2, on the “frijole” monitor, open the “shortcut to FIF Gui” icon.

b) Click on the white arrow in the upper left corner of the Gui to start the software, and wait for the message center to say “Initialization is Complete”.

c) Click the “ON” buttons (green) that say “LB1”, “LB2”, and “CB” (upper left Gui).

d) Turn to Channel 3 on the large monitor and you should see the fiber arms of FIF.

e) On the toolbar, Click “Movement”, and then click on “Stow/Home HRS”. (**while moving the probes, you will get an error message. Just press continue. Do NOT press abort!) You must wait until it is completely done homing before you attempt to click anything else (except “continue” on the error message Gui). Once HRS is done homing (green light goes out), click “Stow/Home MOS A”; again, do not click anything else in the Gui until the probe is done homing (green light goes out). If the

HRS probe is already in the home position, then the homing procedure should be

instantaneous. The same goes for the MOS A probe.

f) Type 242,000 in the “HRS Probe Position” box and click the green “Start” button under “HRS Probe”.

g) Click position update to be sure the value gets to ~242,000 and check visually on monitor for stopped motion.

h) Now that both probes are homed and the HRS probe is moved to the correct position, click off on the “LB1” and “LB2” and click the red button labelled “Both Cameras Off”.

c) next from menu, click TCS-Crockett>Crockett-tss

i. in this window, type ‘tss’ at prompt

ii. wait for message that says to power up the tracker

iii. on the cabinet, push the button labeled “Tracker Power On” Be

sure to check the LED panel in the cabinet. Check that the Hex

limits and the Amp faults on the X-Y Status are green. If any

are lit as red these must be tended to before the tracker can be moved.

Beam Skew LEDs should clear after the tracker is started. Otherwise,

There may be no glycol flow.

iv. then click enter in the tss GUI

d) from pulldown menu, select TCS-Crockett>TCS GUI

19. enable structure, initialize, track, initialize search

c) Next from the toolbar, select Tools>Initialize… and click on the Initialize Search button.

i. This is done to ensure that the tracker initializes properly.

ii. Ensure proper rho initialization on channel 1 of the monitor

20. check weather: Mt Fowlkes & Locke GUI's, Netscape, visually

a) This is done right before you open for the night.

21. open dome, CCAS shutter, louvers, roof vents; jcoff

a) Do a jcoff from jove.

b) On dome GUI, click Shutter>Open Shutter

c)On the louver control box inside the dome, make sure the switch is set to Master instead of Individual and push the button next to it that says Master Open

d)**Before this step, it’s good to feather the louvers individually (to keep sun from shining in on mirror) to equilibrate the temperatures inside and outside of the dome. If you’ve done this, the jcoff command should have already been issued.

e) In the smoke xterm, type jcoff

f) Open roof vents as described in 7d.

22. make sure dome lights are off, go to incandescents in the control room
