Q1 multiple-choice · authority Who is authorized to perform the first installation of a brand-new PhotoRobot device at a customer site?
Explanation: The safety manual is explicit: the first installation after delivery must be carried out by an authorized authority (approved distributor or manufacturer representative). This includes site readiness verification, calibration, warranty activation, and training opportunity for customer staff. Customer staff may observe and learn — but the authority owns completion.
Q2 multiple-choice · electrical Before connecting a PhotoRobot device to the mains supply, what should you verify on the device’s rating plate?
Explanation: Voltage / amperage mismatch can damage the device or create an electrical hazard. Always verify the rating plate matches your mains supply before connecting. Some models also have a voltage selector switch (2.5A / 5A) — selecting the wrong setting burns the unit. If the device and supply do not match, contact an electrician.
Q3 true-false · electrical A PhotoRobot device must always be connected to a properly grounded shockproof socket.
Explanation: Grounding is mandatory. Never bypass the ground pin or use a non-grounded extension cord. If no shockproof socket is available at the installation site, the correct action is to have one installed (or relocate the device) — not to improvise with an ungrounded connection.
Q4 multiple-choice · electrical To disconnect a PhotoRobot device from the mains supply, what is the correct procedure?
Explanation: Always power down at the Control Unit first, then disconnect at the plug (not the cable). Pulling the cable damages the strain relief and the internal wire-to-plug bond over time, eventually creating a fire and electrical hazard. Switching off the wall socket is not equivalent to disconnecting — the device remains energized internally.
Q5 multiple-choice · use A photoshoot sequence is running on the Robotic Arm V8. The arm has just paused between frames but is still powered up. The operator needs to adjust the camera mount. What is the correct action?
Explanation: A powered-stationary device is not safe to approach — it can move at the next command (resume of paused sequence, next frame trigger, or remote operation). The safety manual is explicit: do not approach when the device is moving OR when it is powered up. Always power down at the Control Unit mains switch first.
Q6 scenario · maintenance · weight 2 A PhotoRobot supply cord has developed a small crack in the outer rubber sheath about 5 cm from the plug. The inner wires are not visible. The studio has a critical shoot scheduled in 2 hours. What is the correct action?
Explanation: Damaged supply cord = device must not be used until replaced. The “outer layer only” judgment is not for the operator to make — insulation damage is binary in safety terms. The replacement must be performed by an authority using original specifications. Tape repairs and generic replacements both create electrical hazard and void warranty. Production deadlines do not override safety.
Q7 multiple-choice · cleaning Which cleaning approach is approved for PhotoRobot device surfaces?
Explanation: Surface cleaning must use a damp (not wet) soft cloth with neutral detergent. Water spray and steam are forbidden — they ingress moisture into electronics. Abrasive cleaning pads, solvents, and metal objects damage the surface and can compromise the protective housing. Before any cleaning, the device must be deactivated AND the mains plug disconnected.
Q8 multiple-choice · maintenance Replacing a fuse inside the PhotoRobot Control Unit is classified as:
Explanation: Any task requiring opening the device housing or accessing electrical components is service — authority only. Service uses original spare parts only. Third-party fuses (even if specifications appear to match) are not authorized — manufacturer can decline warranty service if non-original parts are installed. The temptation to “just check” a fuse exists, but the correct action is to contact the authority.
Q9 true-false · use PhotoRobot devices are approved for use in outdoor photography setups, provided the device is protected from rain.
Explanation: PhotoRobot devices are designed for indoor industrial environments only. The safety manual is explicit: “Do not install or use the device anywhere it is exposed to the weather.” This is not about rain alone — temperature swings, humidity, dust, and direct sun all exceed the device’s operational specifications and degrade electronics + mechanical components.
Q10 multiple-choice · working-envelope The Robotic Arm V8 has an elevator range of 32 cm and a swing arm range of 0-90 degrees. Why does the operator need to know these values?
Explanation: Every powered device has a defined working envelope — the spatial volume in which moving parts can reach. Operators must know the envelope of each device they work with and keep themselves and bystanders outside it during operation. Device-specific envelopes are documented in each installation manual.
Q11 multiple-choice · vulnerable A studio is preparing for a customer tour. The customer brings their 6-year-old daughter. What is the correct safety approach?
Explanation: The safety manual addresses children and vulnerable adults: children 8+ can be near the device under supervision OR after receiving safety instructions, with the operator understanding the hazards. Children under 3 require constant supervision. Children must never be allowed to play with the device. The detail that “equipment must never become a toy” matters — even older children left unsupervised can treat industrial equipment as a play opportunity.
Q12 multiple-select · stop-and-escalate · weight 2 Which of the following are valid “stop and escalate” triggers in PhotoRobot safety culture? (Select all that apply.)
Something on the device feels, sounds, or smells wrong
An installed component does not match its rating label
The procedure you’re about to perform is outside your role’s authorization
Someone unauthorized is in the device’s working envelope
You can complete the task in 30 seconds and the manager is not watching
The task is similar to one you’ve done before on a different device model
Pool size: 12 questions. Drawn for module check: 5. Drawn for cert exam contribution: variable per cert weight (~6% Operator, ~8% Hardware Specialist).
All questions have **Source:** and **Explanation:** lines per Academy quiz authoring guidelines.
Mixed types: 7× multiple-choice, 2× true-false, 1× multiple-select, 2× scenario. Roughly matches the recommended distribution; scenario questions weighted 2 for higher cognitive load.
Topic tags enable placement test scoring: authority, electrical, use, maintenance, cleaning, working-envelope, vulnerable, stop-and-escalate.
Option format follows v0.4.2+ convention: markdown list with - prefix per option, bold + ← CORRECT on correct answer (regex-detectable for quiz engine).
Status draft — awaiting KH review before status review → final.
Explanation: Stop-and-escalate triggers protect both operator and equipment. The first four are valid: any anomaly (sense), mismatch (label), authorization (procedure), or proximity (bystander) is a trigger. The last two are NOT triggers — they are rationalizations for unsafe shortcuts. “Manager not watching” and “I’ve done similar before” are the most common precursors to incidents. Safety culture treats them as warning signs, not green lights.
