Powering Up Dipole Magnets:

Use these instructions to recover from loss of a magnet due to a fault (e.g. He level or lead flow fault). The order of actions matters.
(Contact Tech on call if anything behaves funny or things don't respond as expected. Sometimes after a trip an access to the Hall is required to reset things)
1. Wait for Iout=0 (you can't and don't want to do anything while the magnet is in emergency fast dump mode.)
2. While waiting, make a log entry re the fault. Give details such as time, coincident activities, and nature of the fault.
3. Make sure the fault is cleared. (e.g. He level and flow rates returned to normal values and stable)
4. In the HRS Hadron (Electron) Dipole Systems' control panel:
a) Press RESET (verify that all faults are cleared in the middle column)
b) Press START (Display will indicate Power Supply ON and magnet ENGAGED)
Power supply and magnet are ready to go. From here you can return to "Autopilot Mode" (type in desired P0 on control screen and wait) or proceed as described below. For Electron dipole type in desired current in I Set and the power supply will respond.
For Hadron dipole go to HRS HADRON DIPOLE NMR control panel.
1. Press RESET
2. Press Reg. Enable YES
3. Press Search ON (should already be on but it doesn't hurt to check)
4. Type desired field into Field Set (T) field.
5. Wait for field to reach the desired value. (In general it's a good idea to wait about 15 minutes after first reaching the desired field before taking data.) See Hadron Dipole Field Setting for more details and help with trouble shooting.
