==== Switching Extension Legs ====

** Switching Extension Legs **

   - Run current to zero and turn power to quad(s) off if needed.
   - Turn power to leg selection panel on (white lights will come on) if not already on.
   - Push button to select leg.
   - Turn power off (interlock light for beam line will change to leg selected).
   - Turn power on again.
   - Turn quad supply on (switch on right that says "lens power/off").
   - You can now operate quad(s) for selected line.
   - NOTE Quad 4 selection between the R-23 and R-45 beamlines is NOT done by leg selector panel; this is controlled by a switch in the large target room.

NOTE:   Always turn quad power off before attempting to switch legs.   Switching magnet polarty must be done in a separate operation.
