SEA Help

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 
  connect_sea
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 controlmode, you might need to increase the "flow int" value (to 10 or even 100 sec) and reduce the "minimal pulse" value to 0.05 sec.
  • 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. In fixed mode you can also move the motor directly from the needle valve controller by means of the arrow keys.
