[Anchal, Yehonathan, Ian]

We installed c1susaux2 acromag chassis in 1Y0 with c1susaux2 computer. We connected PD monitors, Binary inputs, Binary outputs, and Run/Acquire RTS signals for 6 of the 7 suspensions. We ran out of DB9 cables to connect PR3. Of the ones that were connected, LO2, AS1, AS4, SR2, and PR2 are showing no issues in the functionality from the chassis. For LO1, everything is working except for UR EnableMon channel. The enable monitor does not show an ON state for the coil even though the coil driver chassis shows that it is ON via the LED lights. A possible reason could be that a wire got disconnected when we closed the chassis (there are a lot of wires pushing against each other. Another reason could be that the optical isolator ISO10 could have developed a bad channel on channel 2. The circuit was tested before closing the chassis, so not sure what went wrong after closing it.

PR2 is showing a non-acromag chassis related issue. As soon as we close the loop by enabling the coils, the watchdog triggers because the loop is unstable. Not sure what has changed for PR2, but someone should take a look at it.

For the issue with LO1, I suggest we keep a note that the C1:SUS-LO1_UR_ENABLEMon channel is faulty and don't take its value seriously. We should diagnose and fix this issue once we have more reasons to disconnect the chassis and open it.
