Enhancement Param.
Measurement Parameters (P920 to P923)
Use these parameters to verify Application Parameter programming, when
performing a dynamic material level test over at least 2 empty/fill cycles is
impractical.
Access the following parameters to take an ultrasonic measurement and automatically:
•
display the corresponding Reading in the Parameter Value field.
•
set the mA output value accordingly.
•
set the relay status accordingly.
•
transmit the corresponding point data to the BIC-II (if used).
Note:
If measurements or simulation are desired, however SPL operation has not been
verified, disable all associated process control equipment before accessing the
following parameters.
To take an ultrasonic measurement, access one of the following parameters and
press
(repeat 5 times to overcome Echo Lock, P711).
Alternatively, press
to simulate a rising and falling material level. During the
simulation, the SPL will operate as though the material level was repeatedly cycling
from full to empty to full, and so on, at a rate of 1% of Span (P007) per second. See
Lock (P000) to activate control relays during simulation.
The simulation starts at level = 0, unless a specific level value was entered
beforehand.
Press
to switch to the rising (or for the emptying) simulation as required.
Holding the key increases (or decreases) the simulated rate of rise (or fall), to 4% of
Span per second.
Press
to end the simulation, when desired.
During a measurement or simulation, the SPL display responds as though in the
RUN mode, however the value displayed in the Reading field is affected by the
Measurement Parameter selected, and the material level is displayed in the Auxiliary
Reading field.
P920 Reading Measurement
The Reading corresponds to all associated programming.
P921 Material Measurement
The Reading corresponds to the distance between Empty (P006) and the material
level.
