journey-level elevator constructor. The test covers a wide spectrum of core competencies, from fundamental
electrical theory and motor control to advanced solid-state systems and complex troubleshooting. Candidates will
be evaluated on their ability to interpret technical documents, apply safety codes, and make sound, professional
decisions in real-world scenarios. The exam employs a multiple-choice format to test recall, comprehension, and
application of essential concepts. Each question is crafted to challenge the candidate's critical thinking and ability
to synthesize information from various domains, ensuring they are prepared for the challenges of the modern
industry. Success in this exam demonstrates a high level of proficiency and readiness for professional responsibility.
,SECTION ONE: QUESTIONS 1 – 100
1. A technician is troubleshooting a machine that will not start. Using a voltmeter, they measure 120 VAC
between L1 and ground, 120 VAC between L2 and ground, and 0 VAC between L1 and L2. What is the most
likely cause of this issue?
A. A blown fuse on the L1 line.
B. A defective motor starter coil.
C. An open circuit in the neutral return path.
D. Both L1 and L2 are fed from the same phase.
🟢 D. Both L1 and L2 are fed from the same phase.
🔴 RATIONALE: For a 240VAC circuit, the voltage between L1 and L2 must be 240V. If both lines show 120V to
ground but 0V between them, it indicates they are the same phase. This is often caused by both lines being fed
from the same single-pole breaker or a mis-wired sub-panel. The motor will not start because it requires a
voltage differential across its windings.
2. What is the primary purpose of a phase failure relay in a three-phase elevator motor control circuit?
A. To protect against current overload.
B. To correct power factor imbalances.
C. To prevent single-phasing damage to the motor.
D. To sequence the starting of multiple motors.
🟢 C. To prevent single-phasing damage to the motor.
,🔴 RATIONALE: A phase failure relay monitors all three phases of incoming power. If one phase drops out or
becomes severely unbalanced, the relay de-energizes the motor starter. This prevents single-phasing, a
condition that causes excessive current draw in the remaining phases, overheating, and potentially catastrophic
motor failure.
3. According to ASME A17.1, what is the minimum required rated load capacity for a new traction elevator?
A. It is determined by the architect's specification.
B. 1,000 pounds.
C. 2,100 pounds.
D. It is based on the size of the car and the intended occupancy.
🟢 D. It is based on the size of the car and the intended occupancy.
🔴 RATIONALE: The ASME A17.1 code does not specify a fixed minimum weight. Instead, it requires that the
rated load be based on the inside net area of the car and the intended use, calculated using a specific formula
(e.g., at least 25% of the net car area in square inches for general use). The capacity must be clearly marked in
the car.
4. A solid-state variable voltage, variable frequency (VVVF) drive is used to control an AC motor. In this system,
what component is responsible for converting the AC power from the line into DC power?
A. The inverter.
B. The inductor filter.
C. The converter (rectifier).
D. The IGBT gate control.
🟢 C. The converter (rectifier).
, 🔴 RATIONALE: A VVVF drive is a three-stage device: a rectifier (converter) that changes incoming AC to DC, a
DC bus that filters and smooths the DC, and an inverter that switches the DC back to a variable-voltage,
variable-frequency AC. The "converter" or "rectifier" is the correct term for the first stage.
5. What is the primary function of the mainline brake in a traction elevator system?
A. To hold the car at the floor for leveling.
B. To slow the car down to a stop during normal operation.
C. To mechanically lock the sheave or machine shaft when the car is stationary.
D. To engage and stop the car in the event of an overspeed governor actuation.
🟢 C. To mechanically lock the sheave or machine shaft when the car is stationary.
🔴 RATIONALE: The mainline (or machine) brake is a mechanical brake that is held open by the application of
power to a solenoid coil. In the event of a power loss or when the controller de-energizes the coil, the brake
springs close and mechanically clamp the brake drum, holding the car securely at its position.
6. In a relay logic circuit, what is the result of connecting two normally open relay contacts in series?
A. A logical "OR" operation.
B. A logical "AND" operation.
C. A logical "NOT" operation.
D. A logical "NOR" operation.
🟢 B. A logical "AND" operation.
🔴 RATIONALE: In relay logic, series connections represent an "AND" function because both relays must be
energized for a complete circuit path to be made. Parallel connections represent an "OR" function. A normally
