P11: Output current value 20 mA
Description: Measured value assigned to 20 mA. The transmitted value is in accordance to the primary value (PV) (P01:a).
Assignment can be done that the change in measured value and the change in the output value are the same (normal), or opposite directional (inverse
operation). For example: 1 m level is 4 mA, 10 m level is 20 mA, or 1 m level is 20 mA and 10 m level is 4 mA.
Default value: Maximum measurement range accordance to the nominal length of the device (mm).
P12: - - b a: Output current mode, Error mode
Parameter: P12: b, Output current mode
Description: Current transmitter mode [AUTO, MANUAL]
• b = 0: AUTO, output current value is calculated from the measured value.
• b = 1: MANUAL, The Output current is the fixed current set-in parameter P8. In this case, the output current error setting is not valid either!
Default value: AUTO
Parameter: P12: a, Error mode
Description: “Error indication” by the current output
•
a = 0: HOLD, Error indication has no effect on the output current. In this case, it holds the last valid measurement result at the output.
• a = 1: 3.8 mA, Error indication: the output current gets 3.8 mA.
• a = 2: 22 mA, Error indication: the output current gets 22 mA.
Attention! This error indication is active unless the failure is fixed, or until the failure terminates.
Default value: HOLD
P19: HART polling address
Description: HART polling address of the device (0…15).
The polling address can be set between 0 and 15. For a single instrument the polling address is 0 and the output is 4…20 mA (analogue output).
If multiple units are used in HART Multidrop mode (max. 15 pcs.) the polling addresses should differ from 0 (1…15), in this case the output current will be
fixed at 4 mA.
Default value: 0
P20: Damping time
Description: Damping time is used to damp the unwanted fluctuations of the output and display. If the measured value changes rapidly the new value will
settle with 1% accuracy after this set time. (damping according to an exponential function).
Adjustable values: 0…99 sec.
Default value: 0 sec
