Temptrax Temperature probes
last update: June 7, 2013
When the spectrograph is cabled up and running, the observer can
monitor temperatures in four places in the spectrograph, using the Temptrax
probes.
The IP of the temptrax is maestro-temptrax.mmto.arizona.edu
or 128.196.100.114.
The probes are located as follows:
Probe 1: Grating mount
Probe 2: Slit Area
Probe 3: CaFl Lens Can
Probe 4: Spectrograph Electronics (inside the grey box)
The first 3 of these probes are external to the grey box. They
attach to the outside of the grey box with BNC connectors.
The temperatures may be monitored with the ruby script,
temptrax_gui.rb, which is in the CONDUCTOR
tarball. The temperature readouts are also incorporated into the
CONDUCTOR gui which controls the spectrograph.
Watch the spectrograph electronics temperature. It will overheat
unless the air purge is running, and the galil may crash if the
temperature is too hot.
To run the ruby gui, type
ruby temptrax_gui.rb
at a unix prompt.
If all four of the temperatures do not register, it's not critical; something is loose, and should be fixed.
Whenever you focus the spectrograph, note temperature of the CaFl Lens
Can in the log. Eventually, we will use this information to
provide a model for L1 position versus temperature.
