ALS laser noise eater

(Sheila, Daniel)

This afternoon the noise eater of the ALS laser in H1 EX was oscillating. After some TwinCAT work, we were able to toggle the noise eater off and on remotely. This worked as expected and cleared the noise eater oscillation.

PS. There are 2 relay contacts wired up. Only the first one seems to be needed. I disconnected the second.
