Operation Readiness

A: Chasing instrumentation ghosts wastes hours and risks sign-off with an undersized system that will bite you at SAT. A short-duration pressure drop during a high-flow transient almost always traces back to stored mass in the receiver. From first principles, pressure is proportional to m/V at constant temperature; dump mass fast enough and pressure falls. A regulator limit would show up as a sustained low pressure, not a recovery after the stroke. The correct answer keeps you focused on air inventory, not noise.

A: Getting the order wrong can shear a stem or crack a gearbox, and that’s a schedule killer right before SOP. Mechanical limits exist to protect the drivetrain; you confirm them before applying torque. Torque switches are the last line of defense and need alignment before any powered movement. The correct sequence prevents applying electrical force to an unknown mechanical state.

A: Skipping the hydrotest risks finding a weeping bottom plate after product fill, which means environmental exposure and an emergency drain. API intent is about structural and leak integrity under actual hydrostatic stress, not just foundation response. Settlement data alone doesn’t load welds the same way. The correct answer keeps latent defects from surfacing when it’s too late.

A: Underestimating runtime can force a rushed shutdown and corrupt PLC memory during commissioning. Battery autonomy scales roughly with load for a first-pass estimate. If 10 kVA gives 15 minutes, pulling close to 10% of that stretches runtime several times over. The correct choice keeps expectations realistic without diving into vendor curves.
