All times west coast.

Apr 24 - 10:20:  Deployed from Shana Rae.
Apr 24 - 12:50:  Changed to scheduled mode: 	targetsigma = 4
		 Occurs in the middle of   	minscalefactor = .5
		 R00000/D00*19*			maxscalefactor = .9
						integralgain = .0001
						integralinterval = 300
Apr 30 - 09:30:  Changed maxscalefactor from 0.9 to 1.0
Apr 39 - 16:00:  Changed maxscalefactor to 1.2 and Fudge to 0.7
Apr 30 - 17:00   Put system in safe-mode by issueing a "broadcast off" in the iGo user interface.
May 1  - 08:00   Took system out of safe-mode, will put it back in safe mode if CDIP Sig Wave Height exceeds 2m until the pressure relief valve can be adjusted (probably May 6).
May 1  - 20:44   Changed minscale factor from 0.6 to 0.7.  The sea conditions are very steady right now so it'll be interesting to see if the change of scale factor from 0.6 to 0.7 increases or decreases power generation for the hour before and after the change...
May 3 14:00  Changded minscalefactor to 0.6 due to very calm seas and limited piston motion.

May 7 ~10:00  Took the paragon to the buoy and found high-voltage converter fuses blown.  It was very calm so we replaced the fuses and the TVS's immediately starting to smoke, indicating they had failed shorted.  Removed fuses and will wait to see if pressure relief valve adjustment limits peak powers, then will replace fuses and possibly the TVS's.  Francois and Paul C. dove on the buoy and adjusted the pressure relief valve by 1.5 turns.  This is estimated to limit the peak electrical power coming up to the buoy to about 8500W.
May 15 16:00  Changed the "fudge" factor from 0.7 to 0.55 after observing that a few big waves in a row caused the piston to not retract very far, which then tended to result in the piston hitting the end on the next big wave.
May 15 19:00  Noticed that the plots stopped updating and more alarming the power was reporting at about 1000W continously.  Logged into the buoy buy can not ping the LabJack.  Everything else assessible from ethernet and operating.  App fails to restart, presumably because it can't read the labjack.
May 16 ~11:00  Took the Paragon to the buoy and found water inside the controller box.  There was power at the LabJack but the lights were off.  Installed the spare labjack and cycled power.  Wayne on shore started seeing data files accumulating again.  Inspected other boxes and found some water in the battery boxes as well, but less than the controller box.  The metal power converter box was dry.  Put some duct-tape around the box lids as a mechanical impediment to water, it could help against spray, but not submergence.  Some corrosion evident in the box on various wires, next time we're there we should spray a few of these down with oil or similar.  The labjack itself was well ruined, evidently by a drop of seawater that dripped onto the finer pitch electronics and corroded things all to heck.  Probably next time we're there we should add some tape over the holes in the cover of the labjack...
May 6 14:45.  Switched the system back into "scheduled" mode since it comes up in resistive mode after re-boot.  
						targetsigma = 4
		 			   	minscalefactor = .6
		 				maxscalefactor = .1.15
						integralgain = .0001
						integralinterval = 300
						fudge factor = 0.55
May 16 18:00.  The piston is slipping out to the maximum extent.  The spring pressures are both dropping, indicating gas leaving the system, I think.

May 17 ~18:00.  The buoy went adrift, Francois and Jared anchored it with the Paragon a bit after midnight.
May 20 11:00.  We recovered the buoy and PTO with the Shana Rae.  Upon pulling the system out of the water it was immediately obvious that the high-voltage electrical bulkhead connector that passes into the high-pressure side of the spring had failed, the rubber part had de-laminated from the  brass part of the bulkhead connector.  This is likely due to either the back-pressure of the spring on the connector (which was slightly higher in this deployment), or mechanical stresses due to the cable moving around on the outside, it was not zip-tied to the tie-rods in this deployment.  

Other wear issues are the water in the various plastic boxes, and the plastic bushings between the shackles and the PTO and the shackles and the buoy were heavily worn, perhaps brass bushings would be better there.  The PTO itself appears to be in excellent condition.

May 22.  Power up buoy in Bldg D.  Had to hot-wire the power to the controller box due to terminal strip corrosion in battery box 1.  IGoBox didn't come up cleanly and required a monitor/keyboard to be attached.  It had hung on fsck and needed to be prodded to "fix the filesystem".  Might look into having this happen automatically...  Subsequent shutdown -r now came up cleanly.


May 22.  Post-Deployment efficiency tests performed.
