DRUM PULPER COMPAX DUMPSTER PRESENT PROXIMITY

SWITCH• This was done to prevent the compax

compactor from being pushed back by the Compax “slug.” If the dumpster is pushed back, it can strain the hydraulic cables and cause trash to drop to the ground instead of the dumpster

• I worked with CDE contractors to install a proximity sensor that detects the presence of the Compax compactor dumpster

• The current range of the senor is approximately two feet, but this configurable. Max range is 31.49 in.

• If the sensor does not sense the dumpster, the compax feed conveyor will shut down and the reversing conveyor will feed to the compactor dumpster next to the warehouse.

Compax Compactor Dumpster Present Indicators

DRUM PULPER COMPAX DUMPSTER PRESENT INDICATORS

Both the proximity sensor and the selector switch

indicate the compax compactor dumpster is present. This is normal.

The proximity sensor does not see the dumpster while the selector switch is in the

“dumpster present” position. This would happen

if the compax compactor was pushed away from its

desired position.

DRUM PULPER DUMPSTER FEEDBACK

• This was done to prevent overflows and notify the operators when the dumpsters are not cycling like they should. This decreased the likelihood of upset conditions and operator interaction.

• The feedback comes from signals used in the equipment belonging to Waste Management

• The indicators are linked to these relays, which are wired to the Drum Pulper Control Logix PLC Rack 0

• The indicators will appear on the following screens; Drum Pulper, Stock Supply, Rejects, Dilution Water, and System Summary

• When they are active, the indicators will flash red and black and the text will flash black and white respectively.

DRUM PULPER DUMPSTER FEEDBACK

DUMPSTER FULL• The purpose of these indicators is to prevent

overflows by notifying the partners when the dumpsters are full.

• There are two stages to this indicator: Advanced Warning (AW) and Completely Full (CF).

• In the AW stage, the dumpster is nearly full and should be switched out soon. The respective indicator will blink on and off during this stage.

• In the CF stage, the dumpster is completely full and might be overflowing. The respective indicator will stay solid and flash red and black during this stage.

Inactive Relay

• These indicators are meant to notify the operators when the dumpsters are not cycling like they’re supposed to.

• If left unchecked, this could lead to a premature overflow that the dumpster full feedback wouldn’t detect.

• Indicates when a dumpster has not cycled for 10+ minutes. As of right now, the dumpsters are supposed to cycle every 6 minutes 40 seconds (400 seconds)

• The horn goes off immediately before each cycle.

• The indicator will not appear if the dumpster is full (AW or CF), not present, and there is less than 10 minutes between horns.

RAS #2

• I finished up a project that implemented DCS control between the flow transmitters and the drives at the hypo enclosure.

• Previously, partners had to manually change the drive speed. With the flow meter feedback, the drives automatically maintain a set point entered into DCS

• Assigned I/O in Experion and in PLC 5• Updated drawings in AutoCAD for the

drives, Experion and PLC 5 I/O, and power distribution to the flow meters and pumps.

• Currently, the only system that is not functioning properly is RAS #1

WASTE WATERHONEYWELL DRAWINGS

• While I was working on the hypo pumps, the drawings in DRCS for the Experion I/O and PLC 5 were limited.

• Created I/O drawings for Experion I/O, Rack Layouts, and AC/DC power distribution

• I didn’t have enough time to finish the entire set of drawings, but I’ve handed off the drawing files so they can be finished at a later date

OTHER TASKS• Assisted with attempting to calibrate the metal

detector on the compax side of the Drum Pulper reversing conveyor.

• Assisted with setting up the flat screen TV that is now mounted in the Drum Pulper warehouse with help from Dave Pierson

• Edited some AutoCAD drawings from the Bleaching project.

• Assisted with the selection of a safety proximity sensor for the Drum Pulper dewiring process
