Parameter Settings For Point #10
Parameter Settings For AO-10 mA Output # 10
* Objects near the transducer face (4 mA) cannot be reliably detected. Use controls to
stop the Tripper Car before it approaches the transducers Nearest Distance. (See
Installation
Transducer Mounting.)
With the PLC disabled, enter the RUN mode (or perform a Reading Simulation, P920).
When satisfied with system performance and programming, connect AO-10 mA Output 10
to the PLC.
For a completely automated system, position the Tripper Car via the PLC, based upon
bunker material level, as monitored by the remaining XPL Plus Point Numbers. (See
EXAMPLE 3 - mA Multi-point Average). When both examples 3 and 4 are used, the PLC
may be programmed to operate as follows:
• fill bunker sections to predetermined levels based upon AO-10 mA output 1 - 6
values.
• shuttle Tripper Car to lowest bunker section level.
• if a bunker section "LOE" occurs (3.8 mA), shuttle to the next lowest bunker
section.
• if a Tripper Car "LOE" occurs (3.8 mA on mA Output 10), stop Tripper Car and
material feed.
• when "LOE" subsides, restart material feed.
• when all bunker levels are full, stop material feed and "park" the Tripper Car.
Application Assistance
The preceding examples describe only a few ways in which the XPL Plus can be applied
to process measurement requirements.
P001 Operation No entry required (preset to "3" for distance).
P002 Material Enter "2" for solid.
P003 Measurement Response No entry required (preset to "2" for medium
response, 1 m/min).
P004 Transducer Enter "110" for XLS-60 Transducer.
P005 Units Enter "4" for feet.
P006 Empty Enter "175" for 175 foot transducer face to
Tripper Car max distance.
P007 Span No entry required (preset to Empty, P006 when
P001 = 3).
P070 Failsafe Timer Enter "2" for 2 minutes (14 ft at the maximum
travel rate).
P200 mA Range No entry required (XLS-60 face=4mA*;
far=20mA when P001 = 3).
P219 mA Failsafe Enter "3.8" for 3.8 mA output on "LOE".
