19. In the L_TYPE parameter, select the mode of linearisation for the input variable
→
see the
“Description of Device Functions” manual.

Caution!
Note that with the type of linearisation “Direct” the configuration of the parameter group
OUT_SCALE must agree with the configuration of the parameter group XD_SCALE. Other-
wise the block operating mode cannot be set to AUTO. Such incorrect configuration is indica-
ted via the parameter BLOCK_ERROR with the “Block Configuration Error” message.
Example:
– The measurement range of the sensor is 0...30 kg/h.
– The output range to the process control system should be 0...30 kg/h as well.
The following settings should be made:
– Analog Input Function Block / Parameter CHANNEL (selection of input value): Selection 1
→
Mass flow
– Parameter L_TYPE
→
Direct
– Parameter group XD_SCALE
– Parameter group OUT_SCALE
20. Use the following parameters to define the limit values for alarm and warning messages:
– HI_HI_LIM
→
limit value for the upper alarm
– HI_LIM
→
limit value for the upper warning
– LO_LIM
→
limit value for the lower warning
– LO_LO_LIM
→
limit value for the lower alarm
The limit values entered must be within the value range specified in the parameter group
OUT_SCALE.
21. In addition to the actual limit values you must also specify the action taken if a limit value is
exceeded using so-called “alarm priorities” (parameters HI_HI_PRI, HI_PRI, LO_PR,
LO_LO_PRI)
→
see the “Description of Device Functions” manual.
Reporting to the fieldbus host system only takes place if the alarm priority is higher than 2.
