,Question 1
If a hydraulic elevator will not run down, what is the first thing you should try?
Correct Answer
See if it will run down by opening the manual lowering valve
Question 1: In accordance with ASME A17.1 Safety Code for Elevators and
Escalators, what is the primary purpose of the car top inspection station on a
traction elevator, and which of the following best describes its required
operational characteristics?
A. To allow passengers to control the elevator during normal service at reduced
speed only
B. To provide a means for qualified personnel to operate the elevator from the car
top at inspection speed, with continuous pressure controls and an emergency stop
switch that overrides all other operating devices except the final terminal stopping
devices
C. To serve as a secondary communication system between the car and the machine
room during power failures
D. To automatically level the car at each landing when the doors are open and the
inspection switch is activated
CORRECT ANSWER: B. To provide a means for qualified personnel to operate the
elevator from the car top at inspection speed, with continuous pressure controls and
an emergency stop switch that overrides all other operating devices except the final
terminal stopping devices
Rationale: ASME A17.1 requires a car top inspection operating device that permits
operation only by continuous pressure, limits speed to inspection speed, and
includes an emergency stop switch. This station is intended exclusively for qualified
personnel performing maintenance or inspection and must render normal operating
devices inoperative while remaining subordinate only to the final terminal stopping
devices.
Question 2: When troubleshooting a hydraulic elevator that fails to rise under
load but operates normally when empty, which of the following is the most
likely primary cause based on fundamental hydraulic system principles?
A. A defective door interlock circuit preventing the start sequence
B. Insufficient system pressure caused by a worn pump, internal leakage in the
cylinder, or a malfunctioning relief valve set too low
C. An open safety circuit in the governor overspeed switch
D. Incorrect phasing of the three-phase motor supply
CORRECT ANSWER: B. Insufficient system pressure caused by a worn pump, internal
leakage in the cylinder, or a malfunctioning relief valve set too low
Rationale: Hydraulic elevators rely on system pressure generated by the pump to lift
the load. When the elevator operates empty but fails under load, the most common
causes are inadequate pressure generation or internal bypass (leakage) that
Page 2 of 271
,prevents the system from developing or maintaining the pressure required for the
increased load.
Question 3: According to NEIEP training standards and ASME A17.1, what is
the maximum allowable governor tripping speed for an elevator rated at 200
feet per minute, expressed as a percentage of rated speed?
A. 115 percent of rated speed
B. 125 percent of rated speed
C. Between 115 percent and 140 percent of rated speed depending on the exact
rated speed range
D. 150 percent of rated speed
CORRECT ANSWER: C. Between 115 percent and 140 percent of rated speed
depending on the exact rated speed range
Rationale: ASME A17.1 specifies governor tripping speeds that vary by rated speed.
For elevators with rated speeds of 150 to 500 ft/min, the governor must trip at not
less than 115 percent and not more than 140 percent of rated speed. Precise values
are determined from the code tables based on the elevator’s rated speed.
Question 4: In a traction elevator machine room, which of the following
statements correctly describes the required function of the reverse-phase relay
or phase-failure protection device?
A. It monitors only the voltage level and ignores phase sequence
B. It prevents the elevator from operating if the phase sequence is reversed or if a
phase is lost, thereby protecting the motor from damage and ensuring proper
direction of rotation
C. It is required only on hydraulic elevators with submersible motors
D. It automatically corrects phase sequence without interrupting power
CORRECT ANSWER: B. It prevents the elevator from operating if the phase sequence is
reversed or if a phase is lost, thereby protecting the motor from damage and ensuring
proper direction of rotation
Rationale: Reverse-phase and phase-failure protection is mandated to prevent
motor damage and incorrect direction of travel. The device monitors both phase
sequence and phase presence; loss or reversal of a phase opens the safety circuit
and prevents starting.
Question 5: When performing a static load test on a hydraulic elevator, what is
the correct procedure for verifying the integrity of the cylinder and related
components according to standard testing protocols?
A. Apply 100 percent of rated load and observe for 15 minutes with the power on
B. Apply 125 percent of rated load with the power off and the car at rest, then
measure any downward movement over a specified time period to evaluate leakage
C. Run continuous full-speed trips with 150 percent load for one hour
D. Test only the relief valve setting without applying load to the car
CORRECT ANSWER: B. Apply 125 percent of rated load with the power off and the car
at rest, then measure any downward movement over a specified time period to
evaluate leakage
Page 3 of 271
, Rationale: The static load test for hydraulic elevators is performed with 125 percent
of rated load, power removed, and the car stationary. Any measurable descent
beyond the allowable limit indicates internal leakage in the cylinder, valves, or
piping that must be corrected.
Question 6: Which of the following best describes the operation of a selective-
collective elevator control system under normal traffic conditions?
A. The elevator answers all calls in the order they were registered regardless of
direction
B. The elevator travels in one direction, answering all registered car and hall calls in
that direction, then reverses and answers calls in the opposite direction
C. The elevator only answers car calls and ignores hall calls until the car is empty
D. The elevator parks at the main lobby after every call and waits for the next
registered demand
CORRECT ANSWER: B. The elevator travels in one direction, answering all registered
car and hall calls in that direction, then reverses and answers calls in the opposite
direction
Rationale: Selective-collective control is the most common modern system. It
collects all calls in the current direction of travel, serves them in sequence, and only
reverses direction after the highest or lowest call in that direction has been
answered.
Question 7: In the event of a traction elevator rope stretch that causes the car
to stop above the top landing floor level, which safety device is designed to
prevent the car from striking the overhead structure?
A. The compensating sheave switch
B. The final terminal stopping device (final limit switch)
C. The governor overspeed switch
D. The load-weighing device
CORRECT ANSWER: B. The final terminal stopping device (final limit switch)
Rationale: The final terminal stopping device is an absolute limit that removes
power from the driving machine and brake if the car travels beyond the normal
terminal stopping device. It is independent of the normal control system and is
intended to prevent collision with the overhead or pit structure.
Question 8: When measuring insulation resistance of an elevator motor
winding with a megohmmeter, what is the minimum acceptable value
generally recommended by NEIEP and industry practice for a 480-volt motor
before it is returned to service?
A. 0.5 megohm
B. 1 megohm
C. 5 megohms or the value specified by the motor manufacturer, whichever is
higher
D. 50 megohms
CORRECT ANSWER: C. 5 megohms or the value specified by the motor manufacturer,
whichever is higher
