Known Bugs and Problems
The left part of the SEA client ist blank
Quit the client by closing the window and start a new client.
I can not drive the magnetic field (or any other SE object) from SICS
The command is
drive mf <value>
If you get the following message:
Cannot find mf to drive
ERROR: cannot run mf to 6
then SICS has lost the link to SEA. Enter
from a SICS client. If this does not help, it may be that
the proper device is not selected in SEA.
The needle valve control is unstable
- If you are in automatic mode, switch to controlled mode, and
select the flow by hand (a good flow value is selected when the
heater power at 10 K (stable) is about 0.15 W.
- If you are in controlled mode, you might need to increase the "flow int"
value (to 10 or even 100 sec) and change the pulse length.
- You might also consider to work in fixed mode (after having found
a reasonable needle valve motor position) when not changing
the temperature over a long time.
Restarting the SEA client is sometimes a good idea when problems
arise. Restarting the SEA server is rarely necessary, but might also
help. From the instrument account enter
monit restart sea
to restart the SEA server. Normally, restarting the SEA server does
not harm the instrument program. However, when the SICS server is in
Driving mode, the objects linked to SEA may be lost. In this case
on the SICS prompt.
