140 Endress+Hauser
Deltabar:
– Channel/CHANNEL = 1: Primary value, a pressure or flow value depending on the
measuring mode selected
– Channel/CHANNEL = 3: Pressure
– Channel/CHANNEL = 4: Max. pressure
– Channel/CHANNEL = 5: Level before linearization
– Channel/CHANNEL = 6: Totalizer 1
– Channel/CHANNEL = 7: Totalizer 2
Factory setting:
– Analog Input Block 1: Channel/CHANNEL = 1: Primary Value (primary measured
value)
– Analog Input Block 2: Channel/CHANNEL = 3: Pressure
4. Use the "Transducer Scale/XD_SCALE" parameter to select the desired unit and the block
input range for the process variable.  ä 141, Section 9.3 "Scaling the OUT parameter".
Make sure that the unit selected suits the process variable selected. If the process
variable does not suit the unit, the "Block Error/BLOCK_ERR" parameter reports "Block
Configuration Error" and the block mode cannot be set to "Auto".
5. Use the "Linearization Type/L_TYPE" parameter to select the type of linearization for
the input variable (factory setting: Direct).
Make sure that the settings for the "Transducer Scale/XD_SCALE" and "Output Scale/
OUT_SCALE" parameters are the same for the "Direct" linearization type. If the values
and units do not match, the Block Error/BLOCK_ERR parameter reports "Block
Configuration Error" and the block mode cannot be set to "Auto".
6. Enter the alarm and critical alarm messages by means of the "High High Limit/
HI_HI_LIM", "High Limit/HI_LIM", "Low Low Limit/LO_LO_LIM" and "Low Limit/
LO_LIM" parameters. The limit values entered must be within the value range specified
for the "Output Scale/OUT_SCALE" parameter.
7. Specify the alarm priorities by means of the "High High Priority/HI_HI_PRI", "High
Priority/HI_PRI", "Low Low Priority/LO_LO_PRI" and "Low Priority/LO_PRI" parameters.
Reporting to the field host system only takes place with alarms with a priority greater
than 2.
8. Set the block mode to "Auto" using the "Block Mode/MODE_BLK" parameter, TARGET
element. For this purpose, the Resource Block must also be set to the "Auto" block mode.
Additional configuration
1. Link the function blocks and output blocks.
2. After specifying the active LAS, download all the data and parameters to the field
device.
