CGC 400 DRH 4189340786 UK
7.20.2 4-20 mA
If one of the multi-inputs has been configured as 4-20 mA, the unit range of the measured value correspond-
ing to 4-20 mA can be changed in the PC utility software in order to get the correct reading in the display.
The CGC 400 handles an overcurrent protection for the multi-inputs. If configured as 4-20 mA, and the cur-
rent flow is above 24 mA, the input will automatically switch to resistive mode, in order to protect the HW.
If the current seen from the unit reaches this level, an alarm will be displayed. The text will be "Multi input HW
limit", but no channel will be used. The alarm is raised when any of the multi-input have raised the level of
destruction for current.

7.20.3 Pt100/Pt1000

This input type can be used for heat sensor, e.g. cooling water temperature. The unit of the measured value
can be changed from Celsius to Fahrenheit in the PC utility software in order to get the desired reading in the
display.
Offset parameter is used for compensation of wire resistance in a 2 wire setup.

7.20.4 RMI inputs

The unit can contain up to 5 RMI(resistance measurement input). The inputs have different functions, as the
hardware design allows for several RMI types.
RMI is a resistance measurement input which can be used together with a resistance dependant sensor.
These various types of RMI are available for all multi-inputs:

RMI oil:

RMI water:
RMI fuel:
For each type of RMI, it is possible to select between different characteristics including a configurable one.
The multi-inputs 58 and 59 cannot be used as configurable curves.
7.20.5 RMI oil
This RMI input is used for measuring the lubricating oil pressure.
