Please be mindful of the signs and the floating blue parts.  The pump station is not running so the HEPI can not be isolated.  So, the platform can not be tripped but it can be moved, so again, mind the signs and avoid the blue hardware.  The ability to isolate and so be tripped will not be until all the 4-way valves are changed to the run position and fluid is lowing through the actuators.  I don't want to re-pressurize the flex lines near the open chambers so waiting on doors.

When the HEPIs were locked way back mid September, it was done so with them isolated and it was attempted to lock them in the isolated position.  WHAM4 was locked pretty close, see aLog 38654 for the numbers.  However, since all the alignments and work was down in the locked position, the CART_BIAS SETPOINT which is the servo'd to position, was reset to the locked position.  After unlocking, the large HEPI payload springs were adjusted to reduce the residual=free hang position less the setpoint, as much as possible.  Did manage to get under 3um or urads.  The final adjustments were single springs turned ~1/24th turn.  After isolating or running TFs or ROM tests, this free hanging position will likely change, but, it is a start.  At least the first time it should have no problem isolating and serving to the TARGET locations.  SDF files have been updated but not committed (issues with svn I understand?)
