PARAMETER SETTINGS FOR POINT # 1
P001 Operation Enter "8" for
tripper
.
P002 Material Enter "1" (Use
flat surface
for Tripper Operation.)
P003 Measurement Response No entry required (preset to "2" for
medium
response, 1 m/min).
P004 Transducer Enter "110" for
XLS-60
Transducers.
P005 Units Enter "4" for
feet
.
P006 Empty Enter "325" for
325 foot
face to face distance (tripper at far stop).
P007 Span Enter "275" for
275.0 ft
travel to near stop.
P070 Failsafe Timer Enter "2" for
2 minutes
(14 ft at the maximum travel rate).
P200 mA Range No entry required (preset to
space
, near = 4 ma; far = 20 mA).
P219 mA Failsafe Enter "3.8" for
3.8 mA
output on "LOE".
J5 JUMPER SETTING
Before RUN mode entry, set the DPL+ jumper "J5" (immediately above the Transducer 1 shield terminal) in
the "TRIP" (lower) position, rather than the "NORM" (upper) position.
With the PLC disabled, enter the RUN mode (or perform a Reading Simulation, P920). When satisfied with
system performance and programming, connect mA Output 1 to the PLC.
The Reading displayed when the tripper car is at the near stop is 0.00 ft and 275 ft at the far end stop
(distance from the Span (P007) reference point).
Note that (if used) Relay Setpoints (P112/P113) and MA Setpoints (P210/P211) are referenced to the
Transducer 1 face when the tripper car is at the far end stop. (Enter setpoint values based on the tripper car
travel from "far".)
For a completely automated Tripper Car system, position the Tripper Car via the PLC, based upon bunker
material level, as monitored by a separate level measurement system (e.g. Milltronics XPL+).
APPLICATION ASSISTANCE
The preceding examples describe only a few ways in which the DPL+ can be applied to process
measurement requirements.
The DPL+ can be used to monitor almost any process (within the temperature, measurement range, and
chemical immunity capabilities of the system) where a distance measurement or determination of presence
vs. lack of presence of an object is desired.
By thoroughly reviewing the PARAMETERS sections, you may identify some interesting ways of using the
DPL+ to monitor specific processes.
e.g.1 In a paper mill, one transducer may be used to monitor roll diameter, while the other transducer monitors
the presence of paper to the roll. The paper feed can be stopped based on the roll diameter or a paper break.
e.g.2 For a truck loading station, 1 transducer can monitor truck position while the other monitors load height.
The discharge can be stopped if the truck is out of position or when it’s full, and the discharge chute
can be positioned a minimal distance from the load during filling to keep dust down.
Milltronics has many years experience applying ultrasonic level measurement to a variety of processes in the
mining, aggregate, lumber, grain, chemical, pulp and paper, water, and waste water industries.
If you encounter a difficulty applying the DPL+ to a process measurement requirement, or successfully apply
the DPL+ to a "unique process" we may have never considered, contact Milltronics or your local distributor.
