Technical Reference
Parameter Settings For Point #10
Parameter Settings For LU AO 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 LU AO 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 SITRANS LU10 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 LU AO 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.
