With Laser actuation not connected, I see that the South PMC Servo board is acting up. Firstly, it is not responding to changes made on the ramp when engage is off. This shows that maybe the engage DAC channel is faulty and PMC lock is always on. Need to investigate more on this so for now I have disconnected the PMC PZT from the servo board so that nothing further happens. North side is completely happy and sound. |
