Page 2: Function And System Design
The device can also be operated with backlighting where necessary. In such cases pay attention to the higher voltage drop. When used in conjunction with the Micropilot FMR20 radar level sensor, the RIA15 unit can also be used to make the basic settings for the Micropilot FMR20. The RIA15 must be ordered with the relevant option for FMR20 basic setting in this case. -

Page 8: Performance Characteristics
An additional current-limited current source is required to implement switchable backlighting, e.g. active barrier RN221N. This current source is used to supply the LED backlighting of up to 7 RIA15 process display units without causing an additional voltage drop in the measurement loop. The backlighting can be switched on and off using an external switch. -
