How to fix Frozen Mass-Separator Hall Probes
If the readback from the Pre-separator or Mass-separator Hall Probes freeze and do not update then you should reboot the IOC (IMS:IOC3). This should restore the Hall Probe functionality.. IMS:IOC3 is dedicated to the Hall Probes so rebooting it only affects those readbacks.
NOTE: If you are in the middle of changing mass then be sure to abort the process before rebooting the IOC.
