Troubleshooting Y Manifold Cryo Acceleromter Signal

While investigating the signal on the Y Manifold Cryo Acclerometer, we found that the power conditioner module was not functioning.  We moved the signal to a spare channel and verified that the rest of the signal chain is working.

Robert wants to get the LigoCam software working before we make any other changes to the PEM system, so we are holding off on replacing the channel.

The Y Manifold Cryo Accelerometer signal input and output was moved from S2300063 Channel 15 to S2300065 Channel 15 (one chassis down)

I placed a rubber BNC cover on the bad channel to mark it for repair once we get the green are sure the LigoCam software is working correclty.
