MY Accelerometer Chassis Installed

Continued from previous ALOG75713

Replaced Meggit (Endevco) Accelerometer Power Conditioner with LIGO Accelerometer Power Conditioner. WP11653
S2300076 installed, all signals attached and powered up at 4:03pm PST.

We did have inrush current blow a fuse on the line, we replaced the 10A fast blow with a 3A slow blow fuse and this solved the issue.

The IO chassis did trip when we switched the accelerometer chassis on, I worked with EJ and Jonathan to restore the connection.

To Do:
MX power adapter cable install and signals transferred from Endevco boxes to the LIGO units.
