Modernization & Upgrades Flashcards

What does 'selective modernization' mean in the context of elevator upgrades?

Answer: Upgrading specific components while retaining other existing parts that still meet code

Selective modernization targets specific components—such as controls or doors—while leaving compliant existing components in place to control cost.

When a new microprocessor controller is installed during modernization, what must be provided in the machine room for the new system?

Answer: Updated wiring diagrams reflecting the as-installed condition

ASME A17.1 requires current, accurate wiring diagrams to be available in the machine room so technicians can safely service the system.

During a traction elevator modernization, the existing wire rope is found to have broken wires within the allowable limit but shows significant corrosion. What is the correct action?

Answer: Replace the ropes because corrosion is an independent disqualifying condition

Corrosion is an independent condition requiring rope replacement, regardless of broken wire count, because it compromises tensile strength unpredictably.

A building owner wants to add destination dispatch during a modernization. Which existing system must be replaced or significantly modified to support this feature?

Answer: The hall call fixtures and controller

Destination dispatch replaces conventional hall call buttons with key-pad or touchscreen hall fixtures and requires a new group controller to manage assignments.

What is the purpose of a 'ride quality analysis' conducted before and after a traction elevator modernization?

Answer: To measure vertical and horizontal vibration levels to ensure passenger comfort and proper equipment operation

Ride quality analysis using vibration meters documents baseline and post-modernization performance to confirm the upgrade meets comfort and mechanical standards.

When upgrading an elevator's door operator from a DC motor type to an AC variable frequency type, what must be re-adjusted or verified on the door system?

Answer: Door open and close force limits per ASME A17.1

Door open and close force must be verified and adjusted after operator replacement to remain within ASME A17.1 kinetic energy and force limits.

Which factor primarily determines whether a hydraulic elevator modernization requires a new cylinder (jack) installation?

Answer: Evidence of corrosion, leakage, or failure to pass pressure tests per ASME A17.1

Physical condition—corrosion, active leakage, or failed hydrostatic pressure testing—determines if a jack must be replaced, not age alone.
