Amsco bed moving on its own

If staff is completely sure no leaned onthe controls or had something pushing on them I would replace the hand control. If you have another bed switch the hand controls and see if the problem moves. Chances are the problem will never show up again.

Another cause of this that I've seen several times is in the column itself. Take a good look at the top of the column, where the uppermost part of the column shroud is bolted to the upper frame. If it isn't nice and level all the way around, it was probably lowered onto an SCD or something that the surgical staff had sitting on the base during a case. That bent framework behind the shroud and column cap can cause the exact behavior that your are asking about by shorting different override switches. I've seen this more than once or twice...

The fix is to drop the column shroud sections, raise the table and straighten the inner framwork that the column shroud bolts to. Along the way, pay close attention to the override switch block, the wire bundle that connects it to the override control board, and all associated connectors.

Just as a special side note on all 3080/3085 tables, if you ever have a table with a flickering hand control, remove that hand control from service IMMEDIATELY!!

That "minor" flicker that a scrub team member will attempt to temporarily fix by taping the cord to the side of the remote can cause major problems. That flicker can cause the DC-DC converter on the main control circuit board to burn out. When it burns out, it doesn't fail safe, it fails dead-shorted. Instead of converting the 24VDC down to 5VDC for the power supply controller, it fails as a dead short and feeds 24VDC to the control board in the lid on the power supply. When this happens, it will actually blow the 5VDC trace off of that board. That flickering remote that could have been replaced with new for under $900.00 has now handed you a parts bill for almost $3,000.00.

Hand control looks newer/ in great condition. No flickering of lights. I looked at the skirting around the colum, it looked good. I even unbolted it and let it drop to inspect the wiring in the colum. Everything in the colum looks good. One guy in our group thinks its because of the table being left plugged in and the surgeon activating the ESU. The ESU is inducing noise into the table causing it to move on its own. I was trying to explore all routes to try and figure this out. Thanks for the replies.

Could water get into controls and complete the circuit to move the table?

The water could dry before you get to look at the table.
