  1. An elevator modernization includes upgrading the safeties. When must a new governor be installed along with new safeties?

    Answer: When the governor's tripping speed is incompatible with the new safety's design speed

    The governor must be replaced if its tripping speed does not match the rated speed requirements of the newly installed safeties.

  2. During modernization, an elevator's buffer is found to be oil-type but undersized for the new higher contract speed. What must be done?

    Answer: Replace the buffer with one rated for the new contract speed and stroke

    Buffers must be rated for the actual contract speed; an undersized oil buffer cannot absorb the kinetic energy at the new speed.

  3. What is a primary electrical code requirement when new wiring is installed during an elevator modernization?

    Answer: New wiring must comply with the NEC and ASME A17.1 in effect at the time of the permit

    New electrical installations during modernization must comply with the NEC and the current edition of ASME A17.1 adopted by the authority having jurisdiction.

  4. A property owner wants to increase an elevator's speed from 100 FPM to 200 FPM during a modernization. Which component is most likely to require replacement due to this speed increase?

    Answer: The governor

    The governor must be replaced because its tripping speed is calibrated for the original contract speed, not the new higher speed.

  5. When a hydraulic elevator is converted from a two-speed AC motor to a VVVF pump unit, what operational benefit is achieved?

    Answer: Smoother acceleration and deceleration with improved leveling accuracy

    VVVF drives allow variable pump speed, producing smooth, precise car movement and accurate floor leveling compared to two-speed motor systems.

  6. Which NFPA standard governs the installation of fire-rated hoistway doors that may need replacement during an elevator modernization?

    Answer: NFPA 80

    NFPA 80 covers the installation and maintenance of fire doors and windows, including hoistway entrance assemblies.

  7. During a modernization, the elevator inspector notices the existing hoistway clearances do not meet current ASME A17.1 requirements. How is this typically handled?

    Answer: A variance or equivalency ruling is requested from the authority having jurisdiction (AHJ)

    When existing conditions cannot physically meet current code, a variance or equivalency is sought from the AHJ to document acceptance of the non-conforming condition.
