This menu contains the parameters for the configuration of the analog inputs of the MSLC-2.
Remote Load Reference Input / Process Reference Input
This analog input can be used for two functionalities:
1. Remote load reference input. The input becomes active, if the DI “Setpoint Raise” / “Setpoint Lower” (remote) are closed and the DI “Base Load” or “Imp/Exp Control” is closed.
Figure 3-26: ToolKit – relevant fields for remote load reference input
The load control interacts with the percentage input value shown in field Reference input (parameter 10177). The setting on the right side is the scaling for a minimum and maximum load value while displaying the actual kW setting, which is shown in the field Remote load reference input (parameter 7738).
2. Process reference input. The input becomes active, if the DI “Setpoint Raise” / “Setpoint Lower” (re- mote) are closed and the DI “Process Control” is closed.
Figure 3-27: ToolKit – relevant fields for remote process reference input
The process control interacts with the percentage input value shown in field Remote reference input (parameter 10117). The setting on the right side will display the actual Process reference (parameter 7726). The process en- gineering unit will allow you to display a 4 to 20 mA input as a kW value (Example, there are many engineering units to select). The process signal input and the process reference (remote) will both display the engineering units selected.

kW The process control engineering units are selected here. With this input the reference and the real value can be defined in engineer- ing units for easier customer use.
Process Signal Input
This analog input stands for the process control real signal. The input comes as a hardware signal but the engi- neering values can be selected here. The process engineering units are adjustable and used for visualizing purpos- es. The regulation of the process is done with the percentage value.
