Subject: rack power supplies checked 

Instrument rack power supplies checked and labeled at present loads.

The vacuum rack Sorensen is running HOT! Their is only 0.3A load at 24V There is plenty of space around it.

It is alarming to me because all vacuum valve positions are controlled by this 24V
