Turning power ON
Make sure that the box to the right of the OFF/ON buttons are RED.
...
One special feature is that the DVDD power is coupled between two hybrids (0&1,2&3, and so on). Thus you will see DVDD current of the other hybrid ON even though that hybrid is not "ON". This is expected and normal behavior.
Turning power OFF
Make sure that the box to the right of the OFF/ON buttons are GREEN.
...
One special feature is that the DVDD power is coupled between two hybrids (0&1,2&3, and so on). This means that powering down always results in powering down BOTH hybrids. This is expected and normal behavior.

Low voltage power for the SVT

The applied voltages for the low voltage supplies are hard-coded and cannot be changed.

In EPICS control gui we can click the button to the right saying "Hybrid x" (x=\[0,9\]) and a new GUI pops up showing more options. |

Only the bias voltage can be changed; the low voltages are "hard coded".

This should only be done by expert!

3.3 You should see your number propagate to the Demand V column (this might take 1min, be patient!).
Using the serial interface
In the case where the operation of the power supplies can not be done through EPICS, each power supply can be accessed directly through a terminal. After login into clon10 (see above), the command
