Sample settings for cascade mode
‣
FMG50 settings:
 All FMG50 units used in cascade must be adjusted individually. For example via the
"Commissioning" Wizard in the "Level" operating mode.
The following example refers to a cascade measurement with 2 detectors:
Detector 1: 800 mm measuring range
Detector 2: 400 mm measuring range
1. Settings for RMA42 (analog input 1):
 Signal type: current
Range: 4 to 20 mA
Lower range value: 0 mm
Upper range value: 800 mm
Offset where applicable
2. Settings for RMA42 (analog input 2):
 Signal type: current
Range: 4 to 20 mA
Lower range value: 0 mm
Upper range value: 400 mm
Offset where applicable
3. Calculated value 1:
 Calculation: sum total
Unit: mm
Bar graph 0: 0 m
Bar graph 100: 1.2 m
Offset where applicable
4. Analog output:
 Assignment: calculated value 1
Signal type: 4 to 20 mA
Lower range value: 0 m
Upper range value: 1.2 m
Only the current output of the RMA42 supplies the level measured value of the
overall system. No HART values available for the entire cascade.
