- [I can not drive the magnetic field from SICS|SeaHelpDrive] |
+ !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 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 SEA |
+ 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 |
+ just enter |
+ {{{ |
+ connect_sea |
+ }}} |
+ on the SICS prompt. |
