EIAT EIAT Reading Comprehension and Technical Documents 4 — Questions and Answers
Question 1: A wiring diagram shows a dashed line connecting two components. In standard electrical schematics, a dashed line most commonly indicates:
- A high-voltage connection requiring extra insulation
- A mechanical linkage rather than an electrical connection (Correct answer)
- A future or optional circuit not yet installed
- A ground fault path
Correct answer: A mechanical linkage rather than an electrical connection
In electrical schematics, dashed lines typically represent mechanical linkages or non-electrical connections between components.
Question 2: A maintenance bulletin states: 'Lubricate guide rail clips per Table 3 intervals, EXCEPT when ambient temperature exceeds 90°F, reduce interval by 50%.' If Table 3 specifies 90-day intervals and the machine room regularly reaches 95°F, how often must clips be lubricated?
- 90 days
- 60 days
- 45 days (Correct answer)
- 30 days
Correct answer: 45 days
50% reduction of a 90-day interval equals 45 days when ambient temperature exceeds 90°F.
Question 3: Reading a hydraulic elevator schematic, you see the symbol for a pressure relief valve. Its primary function as described in technical documentation is to:
- Increase fluid pressure when load exceeds capacity
- Prevent system pressure from exceeding a set maximum (Correct answer)
- Filter contaminants from hydraulic fluid
- Regulate fluid temperature during operation
Correct answer: Prevent system pressure from exceeding a set maximum
A pressure relief valve opens to divert fluid flow and prevent system pressure from rising above a preset safe limit.
Question 4: An installation manual contains the sentence: 'The hoistway must be plumb within 1 inch per 100 feet of rise.' For a 250-foot hoistway, the maximum allowable out-of-plumb measurement is:
- 1 inch
- 2 inches
- 2.5 inches (Correct answer)
- 4 inches
Correct answer: 2.5 inches
At 1 inch per 100 feet, a 250-foot hoistway allows a maximum of 2.5 inches out of plumb.
Question 5: A technical specification document uses the word 'shall' repeatedly throughout its requirements. In standards and specification writing, 'shall' indicates:
- A recommended best practice
- A mandatory requirement (Correct answer)
- An optional enhancement
- A future planned revision
Correct answer: A mandatory requirement
In technical and standards documents, 'shall' denotes a mandatory requirement that must be fulfilled without exception.
Question 6: A parts catalog lists a component as 'obsolete — see superseding part #EL-4472.' This notation means:
- The part is temporarily out of stock
- The original part is no longer manufactured; use the newer part number instead (Correct answer)
- The part requires special ordering procedures
- The part is incompatible with current elevator models
Correct answer: The original part is no longer manufactured; use the newer part number instead
An obsolete notation with a superseding part number means the original has been discontinued and replaced by the listed newer part.
Question 7: In a technical troubleshooting guide, steps are numbered 1 through 8. Step 4 reads: 'If condition A is present, proceed to Step 7; otherwise continue to Step 5.' A technician finds condition A is NOT present. The technician should next perform:
- Step 3 again
- Step 5 (Correct answer)
- Step 7
- Step 8
Correct answer: Step 5
When condition A is not present, the instruction directs the technician to continue to Step 5, the next sequential step.
