Transducer Block Configuration
Use the sensor configuration method to set the sensor type to mV – 2-wire for
the applicable transducer block or follow these steps.
1. Set the MODE_BLK.TARGET to OOS mode, or set the
SENSOR_MODE to configuration.
2. Set the SENSOR to mV.
3. Set the MODE_BLK.TARGET to AUTO, or set the SENSOR_MODE
to operation.
Multiple Analog Input or Analog Input Block Configuration
Follow these steps to configure the applicable block.
1. Set the MODE_BLK.TARGET to OOS mode, or set the
SENSOR_MODE to configuration.
2. Set CHANNEL to the transducer block configured for the analog
input.
3. Set XD_SCALE.EU_0 to 20
Set XD_SCALE.EU_100 to 100
Set XD_SCALE.ENGUNITS to mV
4. SET OUT_SCALE to match the desired scale and units for the
connected analog transmitter.
Flow Example: 0 – 200 gpm
OUT_SCALE.EU_0 = 0
OUT_SCALE.EU_100 = 200
OUT_SCALE.ENGUNITS = gpm
5. Set L_TYPE to INDIRECT.
6. Set the MODE_BLK.TARGET to AUTO, or set the SENSOR_MODE
to operation.
