4.2 "output echo loss"
!
Note!
The parameter set "output echo loss" (AX102) is valid only for level measurements. For flow
measurements there is an additional parameter set with a different code: "output echo loss"
(AX112).
The parameters of both sets are described in this section.
4.2.1 "level N" or "flow N" (N = 1 or 2)
Defines the output value in the case of an echo loss.
Selection:
• hold (Default)
The current value is held.
• ramp %/min
After the time defined in "delay echo loss" (see below), the output value is continuously shifted
towards 0% (for a negative ramp) or towards 100% (for a positive ramp). The ramp must be
specified as a percentage of the measuring range per minute ("ramp level N" parameter).
!
Note!
This option is not available for flow measurements.
L00-FMU90xxx-19-00-00-yy-070
A: delay echo loss; B: ramp (positive); C: ramp (negative)
• customer specific
After the time defined in "delay echo loss" (see below), the output assumes the value which has
been defined in the "value level N" or "value flow N" parameter.
• alarm
After the time defined in "delay echo loss" (see below), the instrument generates an alarm. The
output assumes the value defined in "output on alarm" (see above).
4.2.2 "ramp level N" (N = 1 or 2)
(only available for the option "ramp %/min")
Use this parameter to specify the ramp (percentage of the measuring range per minute).
