Issues reported on some ALS WFS channels. Keita and I drove down to EX to investigate. We powered down both the WFS interface and AA chassis and found one channel still showed a high offset count. Power supply voltage was increased to ensure we had 24V at the ISC IO chassis.  IO chassis was powered cycled, offset issue cleared.

Next we looked at the error for the ALS laser. For now we hardwired the interlock on the ALS laser controller. Further investigation needed next Tuesday.
