The primary facility contact is Bill DeGroff. Ted Dunham and Frank Cornelius are also good contacts for facility issues related to IGRINS.


The primary instrument support contact is Kimberly Sokal. Lisa Prato and Greg Mace are also good contacts

1) Instrument Temperatures settings are listed here: Lakeshore Temperature and Heater Settings


The Det SVC temperature sometimes floats by +/-0.5K and the HKP status turns red. This does not impact science and can be ignored. All other temperatures should be stabilized. Contact an instrument support contact if this is not the case.


2) Most problems with the Instrument Control Computer (ICC) can be resolved by restarting the software in question.


     b) Some readouts say 'Err' or '-999' - this means that the communication to the electronics rack is unstable. The ICC should be rebooted. 

These are the different solutions to all the issues with the ICC:


Solution 3: Get help from instrument support. There may be a problem with the network communication or the instrument itself. 

3) The H band detector control computer won't power on.  - We have only seen this issue twice, when the DCCH was shut down in cold weather. Greg suspects that the computer wont start unless above 50F, but warming the whole rack doesn't seem to help. Success has required removing the DCCH from the rack and taking it to a lab bench for testing. This has fixed the boot issue both times and is likely due to the warmer temperature of the work space.
