TSSA EDM-E study plan

TSSA EDM-E · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Elevating Devices Code and Regulation & Elevator and Escalator Mechanical Systems

  • Map the Elevating Devices Code and Regulation domain into a one-page index of the code sections, regulation clauses, and referenced standards it draws on, citing section numbers rather than titles only

  • Define the scope and definitions used in the elevating devices code, listing at least 20 defined terms and writing your own one-sentence gloss for each

  • Identify the categories of elevating devices and the registration, permit, and licensing duties that attach to each

  • Sketch the main mechanical subsystems of a traction elevator (hoist machine, suspension, counterweight, guide rails, car and counterweight safeties) and state the code requirement that governs each

Your checkpoint

A one-page code index plus a 20-term definitions glossary, both cross-referenced to section numbers

Week 2

Elevating Devices Code and Regulation & Elevator and Escalator Mechanical Systems

  • Summarize the inspection, testing, and maintenance obligations imposed by regulation, distinguishing owner, licensed contractor, and inspector duties

  • Explain the process and grounds for orders, suspensions, and enforcement actions under the regulation

  • Describe the mechanical arrangement and function of car and counterweight safeties and governors, and state the code conditions under which they must operate

  • Compare drum, geared traction, and gearless traction machines on suspension, braking, and load-path grounds

Your checkpoint

A two-column duties table separating owner, contractor, and inspector obligations with the clause that creates each duty

Week 3

Elevator and Escalator Mechanical Systems & Elevating Devices Code and Regulation

  • Trace the full load path from car frame through suspension ropes to the machine and building structure, annotating each component with its code-governed design factor

  • Calculate rope safety factors and counterweight balance for at least three worked examples

  • Explain buffer types, stroke, and stopping-distance requirements and how they interact with rated speed

  • Describe escalator and moving walk mechanical systems: truss, step band, drive, handrail, and braking, and identify the code clauses that apply

Your checkpoint

A worked calculation set of three rope safety-factor and balance problems with answers and the governing clauses cited

Week 4

Electrical and Control Systems & Elevator and Escalator Mechanical Systems

  • Diagram a traction elevator power circuit from mainline disconnect through motor drive to the hoist machine, labeling every protective device

  • Explain the logic of the safety chain: which switches are in series, what each one detects, and the order of operation

  • Describe door operator and door interlock electrical circuits and the code conditions that prevent car motion with doors open

  • Identify the electrical requirements for machine-room and machinery-space equipment, including disconnects, lighting, and receptacles

Your checkpoint

A hand-drawn power-circuit and safety-chain schematic with every device labeled and a one-line explanation of its function

Week 5

Electrical and Control Systems

  • Explain variable-voltage and variable-frequency drive operation and how each affects speed, torque, and ride quality

  • Describe the role of the controller, governor, and overspeed detection in stopping the car, and state the redundancy built into each

  • Troubleshoot three fault scenarios from symptom to probable cause to confirming test

  • Explain grounding, bonding, and insulation-testing practices for elevator equipment and why each matters

Your checkpoint

Three written fault-diagnosis scenarios, each with symptom, ranked probable causes, and a confirming test procedure

Week 6

Maintenance, Inspection and Safety Practices & Electrical and Control Systems

  • Build a periodic inspection checklist from the regulation and code, covering monthly, quarterly, annual, and five-year items

  • Describe lockout and tagout procedure for elevator work and the hazards it controls

  • Explain pit, car-top, and machine-room safe-work practices, including stop switches, pit ladders, and fall protection

  • Describe the categories of maintenance records and the retention and reporting requirements that apply to them

Your checkpoint

A complete periodic inspection checklist organized by interval, with the clause cited for each item

Week 7

Maintenance, Inspection and Safety Practices & Elevator and Escalator Mechanical Systems

  • Explain the procedures for annual and five-year load, safety, and governor tests and the acceptance criteria for each

  • Describe the steps of a rope inspection and the retirement criteria that trigger replacement

  • Explain how to investigate an incident or near miss and what must be reported and to whom

  • Identify the personal protective equipment and confined-space considerations specific to pit and machine-room work

Your checkpoint

A written test-procedure outline for annual and five-year testing, listing steps, acceptance criteria, and the governing clause for each

Week 8

Elevating Devices Code and Regulation & Elevator and Escalator Mechanical Systems & Electrical and Control Systems & Maintenance, Inspection and Safety Practices

  • Complete a full timed practice exam across all four domains and score it by domain

  • Review every missed item and write a one-sentence rule you will apply next time

  • Re-derive the five facts you are least confident about from primary sources and write them out from memory

  • Assemble a one-page formula and clause quick-reference sheet you can rebuild from memory

Your checkpoint

A scored practice exam with an error log and a one-page quick-reference sheet

Milestones

Week 2: You can state, without notes, which party holds each inspection and maintenance duty and name the clause that creates it

Week 4: You can draw the power circuit and safety chain from memory and explain the function of every device in the chain

Week 6: You can walk through a periodic inspection from pit to machine room and cite the interval and clause for each check

Week 8: Practice exam score of at least 75 percent overall, with no single domain below 65 percent
