Illustration 22: Electric Wiring Diagram of the Multi-pump (Multidrive) System, Example 1C
1 sensor is connected to all the drives. The redundancy level of the system is low because only the drives are redundant.
• If there is a drive failure, the next drive starts to operate as master.
• If there is a sensor failure, the system stops.
