Illustration 25: Electric Wiring Diagram of the Multi-pump (Multidrive) System, Example 2C
2 drives have individual pressure sensors. The redundancy level of the system is medium because the drives and the pressure sen-
sors are duplicated.
• If there is a drive failure, the second drive starts to operate as master.
• If there is a sensor failure, the second drive (that has a separate sensor) starts to operate as master.
