Start SVT DAQ VNC

From counting house as hpsrun (should already be done):

...

If you see "Interlock" in the last column, means that the Power Supplies are interlocked and need to be reset. It can be done on the expert hps_epics adl of SVT Bias.
On top of the page there is "Reset MPOD interlocks" in red. Click on it and then check if the interlocks are cleared on the the hpsmod webpage

Motor recovery procedure

On Oct 07 2021 we experienced an issue with moving the target from 20um to 8um.
The issue was that the target would not move to 8um when selected from the Epics gui. From the epics gui we saw no indication of problem

To check the status of the motors (SVT TOP, SVT BOT and TARGET) on the motor controller

1) Connect to hpsxps.jlab.org from browser.

2) Login with username and password.

3) Front Panel → Move

4) Check the screen for errors.

5) If one motor says "Uninitialized" click on Initialize and then Home. The motor will be sent home and recalibrated

6) If was just a transient error, this should clear up and recover the motor functionality.
