18. Transducer setup
18.1 Multi-input setup
This applies only to units purchased with the option M4 or G5.
Multi-input 102, 105, 108 are configured to 4-20 mA signals in menus 10980/10990/11000 in the utility SW.
Notice that the 4-20 mA inputs of the option M4 are multi-inputs, and they must be configured correctly in the DEIF Utility SW.
This has to be done as one of the first steps before configuring the transducer inputs.
Normally, these are always kept as 4-20 mA signal inputs.
18.2 Transducer signals
Generator and mains power (active and/or reactive) can be read by the ASC using transducer signals or by using Modbus RS-485.
In this chapter, using the transducer method is described.
Eleven transducer inputs may be available namely four inputs on each of M15:6 (91, 93, 95, 97) and M15:8 (127, 129, 131, 133)
plus the three signals described below concerning to option M4/G5. (102, 105, 108).
Note that the three inputs should be set to 4-20 mA (assuming your transducers are 4-20 mA) before starting configuring this as
described in the section Multi-input setup.
Terminal
Function
103
4-20 mA input for mains power
104
106
4-20 mA input for genset total active power
107
109
4-20 mA input for genset total reactive power

18.2.1 4 - 20 mA values
It is strictly necessary to adjust the 4-20 mA values of the connected transducer. This is done like the following example for a 4-20
mA mains transducer with the configuration of:
