Check the safety circuit on the KGTSM PWB

Hazard: Disconnecting CN451 of the KGTSM PWB (source's own verbatim caution)

Consequence: Disconnecting CN451 turns OFF the power of the tilt motor, rotation servo system, couch, etc.; if the safety circuit is defective or if your operation was incorrect, the tilt, rotation motor, or couch may move

Avoidance: Disconnect CN451 of the KGTSM PWB before running the safety-circuit checks below, and keep it disconnected throughout the tilt / vertical-movement / horizontal-movement sub-checks

Hazard: Starting the safety-circuit checks without first confirming the area and the CN451 disconnection (source's own pre-check checklist, not itself labeled CAUTION but stating an electric-shock and crush hazard)

Consequence: a worker touching parts that may cause an electric shock, or a worker or object present at a location where they may be crushed, once CP1 power and commanded tilt/vertical/horizontal motion resume

Avoidance: Before starting inspection work, confirm no workers are touching parts that may cause an electric shock, confirm no workers (or objects) are present at a location where they may be crushed, and confirm CN451 on the KGTSM PWB is disconnected
