TOWER
FEE ALARMS/RECOVERY:
- Crate status/alarm
- Check power via CANBus screen and turn supplies on if found off:
- dual supply #94 - tower crates 1&2
- dual supply #92 - tower crates 3&4
- dual supply #93 - tower crates 5&6
Do "Master Reload" to restart everything correctly.
If there are troubles
with individual crates after a few tries, see next:
- On tower FEE individual screens (persistent trouble and/or not solved
with "Master Reload"):
- Re-configure crates & load peds for each crate in question
(e.g., via load, write, read on individual FEE crate screens) --
make sure FEE boards go back to "run" mode at end
- Similarly re-load LUT's to affected crates (power cycle reloads default
LUT)
- For crates that don't want to configure the soft reset in the "resets"
pop-up window can be used
- Temperature alarm
-- these are readings from crate controller
- If temperature is high for all crates -- likely air blower or duct
system failure
- Running without air cooling can damage FEE electronics (and in any case
the temperature dependent electronic drifts will render the data unusable)
- Turn off power to crates and investigate with (experts) access ASAP
- Temperature is high for a (one) crate
- Either excessive power use by electronics (failure) or individual
crate air duct problem
- As above ... turn off power to affected crate(s) and investigate with
(experts) access ASAP
- or, if one crate affected it could be temperature increase in WAH coupled
with tight crate controls level.
- Controls (VxWorks IOC)
failure/hangup -- GUI "all white"
- Tower crate configurations still loaded (could continue
running a bit), but to gain slow control/monitoring reboot VxWorks (impacts
other controlled systems!)
- As described elsewhere (see HVSys section) 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, CANBus connect to crate #90 & "SysReset"
- Follow reboot progress on IOC monitor
- Monitor tower FEE GUI screens
- System may come back up and monitor (set "installed" mode) without
errors and overall green status for all crates
- However, a re-configure of the crates ("load, read, write" all + LUT
write -- e.g., do "Master Reload") won't hurt and likely is best procedure
- Note: when crate power is cycled or
restored -- for whatever
reason
- All affected crates (remember the supplies service 2 crate each)
must be re-configured and LUT's downloaded ("Master Reload")
