Run Checklist

(This page can be found online at:

and the physical paper checklist is also available online at:

For establishing operating positions, use the following physical checklist:

This is a list of all tasks that need to be performed when pots are to be inserted close to the beam. If additional information is needed on a task, click on the link to get to the detailed information. Some items on this list only pertain if pots are being moved. Ignore them if you are not moving pots.

Review the Emergency Procedures before starting to move the pots so they are fresh in your mind.

Also review FPD Issues to understand the current state of the system.

!!!!!IF ANYTHING STRANGE HAPPENS, TURN OFF CONTROL LINES!!!!!

Afterwards, try looking at Troubleshooting to resolve.

Emergency / Strange Behavior

EMERGENCIES: IMMEDIATELY TURN OFF 5V CONTROL LINE if they are on (bring problem pots home when control is restablished at end of store). Click on link below for procedure to recover from problem.

If you have a Driver Failure, try turning the Control Line on and off to clear it.


ALARMS THAT AUTOMATICALLY STOP POTS
  1. Rate exceeds 500kHz and control line on. Turn off control line. Try to determine why rate got so high. If it is not due to a failure of the pot motion, and the pot can be retracted to a safe operating position, lower trigger HV (to bring rate slightly below 500kHz), retract pot and return voltage to 100%. Cannot move pot until rate is below 500kHz.
  2. LVDT value exceeds software limit. Turn off control line. Try to determine why pot moved to software limit. It is safest to wait until end of store to try to remove the pot.
  3. LVDT value exceeds wanted position. Turn off control line. Try to determine why pot didn't stop. It is safest to wait until end of store to try to remove pot.
  4. LVDT direction doesn't match wanted direction. Turn off control line. If the problem was because of an LVDT fluctuation, you can issue the command to move again with no problems. If the alarm was for any other reason, wait until the end of store to try to remove the pot.

IMPORTANT EMERGENCY PROBLEMS
  1. Pot Motion Program freezes or PC crashes.
  2. Power PC (VME Crate) crashes.
  3. Pot already at final position (position closest to beam) starts to move further in.
  4. Pot does not stop at designated final position (position closest to beam).
STRANGE BEHAVIOR OF MOVING POT: ISSUE INDIVIDUAL POT STOP COMMAND, ALL STOP COMMAND OR EMERGENCY STOP COMMAND (bring problem pots home when control is restablished). Click on link below for procedure to recover from problem.
  1. Pot starts moving home by itself (if stop doesn't work, let it go home and make sure it doesn't come back in).
  2. Pot part way in starts moving in by itself (if stop doesn't work, turn off 5V).
  3. LVDT is not updating while pot is moving (if stop doesn't work, turn off 5V).
  4. Pot doesn't stop at the designated position which is not final position (if stop doesn't work, turn off 5V.)
STRANGE BEHAVIOR POT NOT OBEYING COMMANDS. Click on link below for procedure to recover from problem.
  1. Pot doesn't move when given move command by software.
  2. Pot doesn't move home when given command by software.
  3. Pot doesn't move home with emergency line.
OTHER STRANGE BEHAVIOR. Click on link below for procedure to recover from problem.
  1. Rates are not updating.
  2. HV not responding or tripping.
  3. ACNET not updating.
  4. Major SES Alarms.
  5. Examine not working.
SMOKE ALARM

NOTE: Spurious Smoke Alarms appear at beginning of stores during shot setup. This appears to be due to Rack Monitor power during shot setups. INCIDENT REPORT

If anything strange happens that requires an emergency procedure to fix, we need to create an incident report. This should be sent to the dofpd_all list with the detailed report of the run as well as recorded in an incident log book in the SCR.

Gather as much of the following information as possible:
