6.6.7 Magnetic pickup unit (MPU) input wiring
INFO
If you use the MPU input, you cannot also use the W input. Connecting both the MPU and W inputs at the same time will
lead to incorrect readings.
The MPU input wiring is shown in the following diagram. The MPU terminal connections on the DEIF equipment can be switched
around without any problem. If an MPU is used, a wire break can be detected.
6.6.8 W input wiring
The W input can be used for a signal from one of the phases of the generator, or for an NPN or PNP input.
INFO
If you use the W input, you cannot also use the MPU input. Connecting both the MPU and W inputs at the same time will
lead to incorrect readings.
The connection of the W output from the generator is shown below.
