Controls failure/hangup --
HVSys GUI "all white"
If this occurs, likely other systems affected as well.
- HV values are still loaded in CW cells (could continue a bit if
running during a store), but to gain slow control of HVSys one must reboot
VxWorks -- this (at present) turns off HV and reloads values
- When ready -- reboot EEMC slow controls IOC
- From existing VxWorks monitor window (or get via "telnet eemc-serv 7007")
type reboot at prompt, or do a "ctrl_x" to force a boot
- Alternatively, use CANBus connection to VME crate #90 and click on
"SysReset"
- Follow reboot progress and messages to IOC monitor until startup script
finishes
- Monitor HVSys GUI for progress
- Hopefully the 3 controllers will
come back with big green (communication) dots (the corresponding branches
may be enabled or not)
- Similarly, the body of the GUI should turn gray for all boxes indicating
voltages are loaded and cells ready to ramp up
- If above 2 conditions are satisfied ... click "on" HV with
button in GUI
center and system should come up in a few minutes
- If not ... refer to "Controller and CW cell communication
errors" section (above) and restore control
and base loaded values ...
- Note: the VxWorks reboot will affect also the tower FEE and MAPMT systems
(although they also will stay configured if continuously powered)
... see tower and MAPMT trouble sections -- or Recovery & Restart --
for control restore action
