How to Remote Operate the Chiller

1) Log onto the PC
Open any Java-capable browser and direct to "129.57.57.188:5800" and enter the password. 
Contact Dave Kashy (x7275), Ashot Gasparian (x7914), or Jarreas Underwood (x6331) if you 
need access.

After a short delay you should see the screen of the PC in the browser. On the top left are four 
buttons - "Disconnect" is the one you use to log off and end the session. 

2) Start the WinChill Software
Go to Start -> Shortcut to Common, and find the "WINCHILL 32 V1" shortcut. Doubleclick on it. 
Do not open the software from Start -> Programs -> HyCal Stuff -> WinChill Applications as that 
shortcut does not have the correct formatting. A "System Unlocked" text box should appear - hit 
"OK."

2.5) The WinChill window should open up, but there won't be a Level Alarm button. Go to File -> 
Open and choose "Controller With Level Alarm." A red Level button should appear.

3) Connect to the Chiller
Go to Options -> Remote Station Setup. "HyCal Chiller" should be the only option, and 
highlighted. Hit Edit and verify that:
Title: HyCal Chiller
WinChill Address: 1
Device Type: Fuji (you'll have to select this from the drop-down menu)
Device ID:1

Hit Ok twice.

Go to Options -> Comm Port Setup. Verify that:
Port: COM1
Baud: 9600
Parity: Odd
Both Intervals: 4 seconds.

You shouldn't have to change anything, but you have to set up the port anyway.

After a short delay (up to 15 seconds or so) the PV and SV should change from zero to the 
current temperature and setpoint. The "out1" light should be green.

If the PV and SV number do not change, shut down the program and try starting it again. Failing 
that, reboot the machine and run WinChill before opening LabVIEW.

4) What the Lights Mean
PV = The temperature of the liquid leaving the chiller.
SV = Setpoint Value = The temperature you want.
out1 = unknown
out2 = unknown
Alm1 = Alarm 1 = The temperature of the liquid leaving the chiller is 30 degrees or warmer.
Alm2 = Alarm 2 = The temperature of the liquid leaving the chiller is 5 degrees or colder.

5) How to Change the Temperature
Go to Options -> Setpoint -> Adjust. The current Setpoint and Manual MV should fill in. If they 
don't, shut down the software and restart - something didn't connect properly. Assuming they do, 
fill in the Setpoint you want and click on OK (do not hit return). After a short (up to 15 second) 
delay the SV should change, with the PV following as the chiller goes to work.

Warning: Before changing the Setpoint, verify that the current temperature gradient is less than 
0.5 degrees per hour for the lead glass, and less than 0.25 for lead tungstate crystals. Do not 
change the SV by more than two degrees in any case.

6) How to Turn the Chiller On/Off
Go to Options -> Unit Options -> Start/Stop Unit. Hit "Stop" in the window that appears. You do 
not need to enter a channel number as there is only one chiller attached to the PC. 

Please note that if you stop the chiller in this way, you may not be able to turn it back on manually 
– you should turn the chiller off and back on using WinChill.

7) If you want a Temperature vs Time Graph
Go to Options -> Poll. A blue light next to the word "Poll" should appear, and the graph will start. 
There is no way of adjusting the scales on this graph.
