The PR hi-power motor driver (scsmotor11, IP 172.16.1.211) was malfunctioning this morning. Only the first of the four hi-power channels is used and connected to PR top screw while the remaining low power outputs are connected to F0-F3 fishing rods. The hi-power section is not working and the corresponding LED is OFF as shown in the photo. Simply replacing the fuse did not solve the problem. This has been verified both with the top screw motor and with an external test motor. Therefore the driver will be replaced with a spare in one of the next maintenance breaks. The operation is not very urgent since the motors used to compensate the suspension thermal drifts are connected to the low power section that is still working properly.
This morning, during maintenance break, the defective high-power motor driver at PR has been replaced with a spare (scsmotor44, IP: 172.16.1.244). The functionalities of all channels (top screw, F0-F3 fishing rods) has been successfully verified.
