Examiner:
Florida employers and training providers may use competency-based industrial
maintenance assessments. Florida does not have a single statewide Industrial
Maintenance Technician licensing examination; this practice test is designed around
common industrial maintenance competencies used in manufacturing, utilities, and
industrial facilities.

QUESTION 1.
A centrifugal pump repeatedly trips its motor overload approximately 20 minutes
after startup. Inspection confirms correct supply voltage, normal bearing
temperatures, and no evidence of mechanical binding. Which condition should be
investigated first because it is most likely to increase motor current while allowing
normal startup?
A. A partially closed discharge valve creating operation far to the left of the pump
curve
B. Impeller wear increasing internal recirculation
C. Reduced suction pressure resulting in cavitation
D. A process change causing the pump to operate significantly farther to the right of
its best efficiency point
Correct Answer: D. A process change causing the pump to operate significantly
farther to the right of its best efficiency point
Explanation: Operating well to the right of the best efficiency point often increases
flow demand and brake horsepower, causing motor current to rise until the
overload trips. A partially closed discharge valve generally reduces pump load.
Cavitation primarily damages components and reduces performance, while
impeller wear typically decreases hydraulic efficiency rather than producing the
greatest sustained overload condition.

QUESTION 2.
Following replacement of a three-phase motor, the conveyor operates in the correct
direction but experiences excessive vibration that increases with speed. Laser
alignment readings are within tolerance, and vibration is predominantly at twice
running speed. Which condition is the most probable cause?
,A. Electrical phase imbalance
B. Angular shaft misalignment under operating conditions
C. Insufficient lubrication in the gearbox
D. Belt slippage during acceleration
Correct Answer: B. Angular shaft misalignment under operating conditions
Explanation: A dominant vibration component at approximately twice running
speed commonly indicates angular misalignment, particularly when thermal
growth changes alignment after startup. Electrical imbalance usually produces
different vibration characteristics, while lubrication deficiencies and belt slippage
generally exhibit different symptoms and frequencies.

QUESTION 3.
A PLC-controlled packaging line intermittently skips one product every several
hundred cycles. Inputs and outputs test normally during manual operation. Which
troubleshooting approach is most likely to identify the underlying problem
efficiently?
A. Replace every field sensor associated with the sequence
B. Increase motor overload settings to eliminate nuisance trips
C. Trend PLC input status and sequence timing while the system operates under
production conditions
D. Disable diagnostic alarms to prevent interruptions during testing
Correct Answer: C. Trend PLC input status and sequence timing while the
system operates under production conditions
Explanation: Intermittent faults are best diagnosed by monitoring real-time input
transitions and program timing while the machine operates normally. Random
component replacement is inefficient, and changing overload settings or disabling
alarms does not address the root cause while potentially creating additional risks.

, QUESTION 4.
A maintenance technician is preparing to service equipment supplied by multiple
energy sources, including electrical, pneumatic, hydraulic, and stored mechanical
energy. Which action best satisfies accepted lockout/tagout principles before work
begins?
A. Isolate only the electrical supply because it presents the greatest hazard
B. Place warning signs near the equipment and rely on operators to avoid startup
C. Shut down the machine using the HMI emergency stop only
D. Isolate every hazardous energy source, release or restrain stored energy, verify
zero-energy state, and document the isolation before maintenance
Correct Answer: D. Isolate every hazardous energy source, release or restrain
stored energy, verify zero-energy state, and document the isolation before
maintenance
Explanation: Effective hazardous energy control requires identifying every energy
source, isolating each one, controlling stored energy, and verifying that the
equipment has reached a zero-energy state before work begins. Emergency stops
and warning signs alone are not energy-isolating devices.
────────────────────────────────────────
QUESTION 5.
A hydraulic cylinder drifts under load even after the directional control valve has
been centered. External leakage is absent, and system pressure remains within
specification. What is the most likely cause?
A. Internal leakage across the cylinder piston seal
B. Excessive pump displacement
C. A clogged suction strainer
D. Overfilled hydraulic reservoir
Correct Answer: A. Internal leakage across the cylinder piston seal
