Questions 1–40 of 200
(Each question includes multiple-choice answers + deep technical rationale)




Question 1

When an elevator constructor describes a normally open (NO) contact or a making contact, he or she is
describing the same contact configuration.

A. True
B. False
C. Only in AC circuits
D. Only when used with relays

✅ Correct Answer: A – True

Rationale:
A normally open contact and a making contact both describe a contact that is open in its normal (de-
energized) state and closes when actuated. These terms are interchangeable in elevator schematics and
control logic.



Question 2

,As current flows through a relay’s coil, what is generated by the coil that pulls or picks the relay’s armature?

A. Static charge
B. Heat
C. Magnetic field
D. Back EMF

✅ Correct Answer: C – Magnetic field

Rationale:
Current flowing through a coil creates a magnetic field, which attracts the relay armature and changes the
state of the contacts. This electromagnetic action is the basis of relay operation.



Question 3

The most common relay used in modern elevator control systems is the plug-type relay.

A. True
B. False
C. Only in DC systems
D. Only in traction elevators

✅ Correct Answer: A – True

Rationale:
Plug-type relays are favored due to ease of replacement, reliability, and minimal downtime, making them
standard in modern elevator controllers.



Question 4

The majority of today’s set/reset relays operate by using two independent coils mounted on a common relay
base.

A. True
B. False
C. Only when timed
D. Only in AC systems

✅ Correct Answer: A – True

Rationale:
Set/reset relays use one coil to set (latch) and another to reset (unlatch), allowing the relay to maintain state
without continuous coil energization.

,Question 5

What prevents two or more relays from becoming energized electrically at the same time?

A. Mechanical latch
B. Electrical interlock
C. Overload relay
D. Dashpot

✅ Correct Answer: B – Electrical interlock

Rationale:
Electrical interlocks use auxiliary contacts to block competing circuits, preventing conflicting relay
operation and ensuring proper sequencing.



Question 6

What electrical component allows current to flow in only one direction?

A. Capacitor
B. Resistor
C. Diode
D. Transformer

✅ Correct Answer: C – Diode

Rationale:
A diode permits current flow when forward-biased and blocks it when reverse-biased, acting as a one-way
electrical valve.



Question 7

In a DC circuit, a diode that has a negative voltage on the bar (cathode) side is in what condition?

A. Reverse biased
B. Shorted
C. Forward biased
D. Open

✅ Correct Answer: C – Forward biased

, Rationale:
When the cathode is negative relative to the anode, the diode conducts, placing it in forward bias.



Question 8

Dashpots are timers that use oil flow to control their tripping time.

A. True
B. False
C. Only pneumatic dashpots
D. Only electronic timers

✅ Correct Answer: A – True

Rationale:
Dashpots are mechanical timing devices that rely on controlled oil movement to delay relay action.



Question 9

Timing circuits that use capacitors and resistors (RC networks) are limited because the timing is not
adjustable.

A. True
B. False
C. Only in AC circuits
D. Only in DC circuits

✅ Correct Answer: B – False

Rationale:
RC timing can be adjusted by changing resistor or capacitor values, though accuracy can be affected by
temperature and component aging.



Question 10

When the main line is referred to as “cold” or “dead”, it means there is no power to the elevator controller
or drive.

A. True
B. False
C. Control power only is off
D. Motor power only is off
