Simulator
A machine with a hidden fault. Decide what to inspect, measure, isolate and repair; the simulator reveals evidence from the machine’s actual state and scores the path you took to the answer.
Unlike the guided missions, nothing here is scripted. A mission gives you a fixed set of checks with one trap and walks you through the reasoning; a scenario gives you the whole machine, and the same action reads differently depending on what is actually wrong with it.
What it measures are eight troubleshooting patterns — moves chosen because they should carry over to equipment this simulator has not modelled. That is the design intent, not yet a measured result. Learn mode names the ones each machine offers.
beginner
Line 4 case conveyor · Apprentice or first-year technician · 20 min expert path
Line 4 conveyor will not start. Operator says it stopped on its own and the start button does nothing.
beginner
Line 4 case conveyor · Apprentice or first-year technician · 28 min expert path
Line 4 conveyor keeps stopping and saying the infeed is blocked when there is nothing there.
intermediate
Line 4 case conveyor · Maintenance technician, 1–3 years · 53 min expert path
Line 4 conveyor keeps tripping. The operator has reset it twice and it trips again within seconds.
intermediate
Line 4 case conveyor · Maintenance technician, 1–3 years · 64 min expert path
Operator presses start on Line 4 and nothing happens at all. No noise from the panel, no movement.
advanced
Line 4 case conveyor · Senior technician · 53 min expert path
Line 4 drops out on a speed fault a couple of times an hour. Resets fine and runs. Worse when we run the big cases.
beginner
P-201 transfer pump · Apprentice or first-year technician · 24 min expert path
P-201 cannot hold the header up. Pressure sits around 38 psi no matter what the drive does.
intermediate
P-201 transfer pump · Maintenance technician, 1–3 years · 67 min expert path
P-201 is running but the process header is down to about 40 psi. Operator says the pump sounds rough.
intermediate
P-201 transfer pump · Maintenance technician, 1–3 years · 56 min expert path
HMI says the header is at 41 psi and the pump has ramped to full speed, but downstream is not complaining and nothing has changed on the line.
advanced
P-201 transfer pump · Senior technician · 73 min expert path
P-201 came back from a motor swap last night. It runs, it makes pressure, but the header will not get past about 22 psi and the line is being throttled.
beginner
PK-3 case packer · Apprentice or first-year technician · 91 min expert path
PK-3 has been getting slower all week and the cases are coming off loose — the clamp does not seem to be holding them square any more.
intermediate
PK-3 case packer · Maintenance technician, 1–3 years · 62 min expert path
PK-3 keeps stopping partway through the cycle. The panel says the clamp did not close, but the operator says it looks closed to her.
intermediate
PK-3 case packer · Maintenance technician, 1–3 years · 71 min expert path
PK-3 was fine Friday. This morning the whole machine is sluggish — not one thing, all of it — and it is missing rate badly.
advanced
PK-3 case packer · Maintenance technician, 3+ years · 69 min expert path
PK-3 stopped clamping in the middle of a run yesterday afternoon. It gets to the clamp step and sits there.
Six dimensions: diagnostic accuracy, evidence quality, efficiency, safety, repair quality and verification. Naming the right component is 30 of 100 — the rest is how you got there, whether you worked safely, and whether you proved the repair. Swapping parts until the machine runs scores substantially lower than reasoning to the same answer, by design.
