Troubleshooting guide
7. You are now ready to initialize FLAMINGOS! This is done by running the command initflam.pl. This
script initializes agents and displays the following windows:
Temperature Daemon - This daemon reads temperatures from two different sensors in FLAMINGOS with
the following output written to the screen:
UFLakeShore208Agent::ancillary
>new reading:(2002:170:05:24:06.920436) 1,75.67 6,82.73
You should always keep an eye on the array temperature ( ~76 K, in the example above where it says
1, 75.67 ) and the MOS dewar temperature (~83 K, where it says 6, 82.73 in the example
above). The array temperature should never vary by more than ~0.5 K. The MOS dewar temperature
must remain below 200 K for sucessful imaging. In normal operation the temperature varies between
~78 K and ~95 K in a sawtooth pattern, depending on the time since the last cryogen fill and the
attitude of the instrument; if you are doing MOS observations, please do not let it warm up above 95
K, as the Decker and MOS wheel mechanisms may bind up. Please contact Dick Joyce, Ron Probst or
Nick Raines if the MOS dewar deviates from this behavior.
Record Temps window - This window logs both temperatures every 10 minutes. It is sometimes easier to
monitor the array and MOS dewar temperatures from here. Please do not close this window or the
associated xterm to which messages are printed; you can minimize the xterm messaging window.
Motor Daemon - This daemon controls the motors which move all of the wheels. If the motor daemon
does not initialize, answer n (for no) to initflam.pl's query about continuing, close the motor
daemon window and run initflam.pl again.
MCE4 Daemon - This daemon runs the array controller, referred to as MCE4. The first time this daemon
is run, if initflam.pl says it is not ready, look at the MCE4 daemon. If it is printing a string of
messages about uninitialized semaphores, quit initflam.pl, close the MCE4 daemon window, and
type ufstop.pl -clean at the 4mguest@flmn-4m-1a prompt. Type control-c after
ufstop.pl has printed several lines of text and has paused without returning the cursor. Then run
initflam.pl once more.
UFSTATUS GUI - This window displays the temperatures, the bias voltage on the array, and the positions
of all of the wheels. Please do not close this window or the associated xterm to which messages are
printed; you can minimize the xterm. Note that it is NOT updated automatically. Rather you must
click the update button in the middle of the GUI for the most recent values and positions. DO NOT
press the update button while any of the wheels are moving.
Array Temperature Quick Look Plot Tool – This GUI will appear, along with an xterm messaging
window. Please do not close this window or the associated xterm to which messages are printed; you
can minimize the xterm. After about 30 minutes there will be ~3 points in the Record Temperatures
log file, and you can hit the Update button to plot the present temperature.
MOS Temperature Quick Look Plot Tool – This GUI will appear, along with an xterm messaging
window. Please do not close this window or the associated xterm to which messages are printed; you
can minimize the xterm. After about 30 minutes there will be ~3 points in the Record Temperatures
log file, and you can hit the Update button to plot the present temperature.
