Comment to F0 vertical and yaw stepper motor limit switch installation. (15583)

With Hirata-san, Yano-san.

We tested the IP limit switches made by Nikhef. We pressed them with an Allen key and checked the signal in the medm screen when pressing the update button.

  • All the switches are in the place expected by the medm screen.
  • With the exception of the switch (H1, -Yaw, Left) and (H2, -Yaw, Left), all of them worked well.
  • The switches (H1, -Yaw, Left) and (H2, -Yaw, Left.) produce signals indicating they are pressed, although they are not. There's an illustrative  drawing in SR2 notebook. They have be to fixed.
  • In the case of (H1, -Yaw, Left) the head of a screw anchoring the spring blade is close to the switch and it may be causing trouble, but we are not sure. We wanted to check with the camera but the camera is currently out of service. We need to check again.
