NEIEP MX Review Exam Questions With Accurate Answers.
Anti creep leveling distance - accurate answers-Engage within 1 inch of
leveling zone
Controller clearance - accurate answers-36 inch clearance between line parts
a wall / 30 inch working clearance
Relief value pressure setting - accurate answers-150 percent working
pressure Max
Manual lowering max speed - accurate answers-20 foot per minute
One gallon to cubic inches - accurate answers-231 cubic inches
Escalator speed - accurate answers-90 - 120 ft/min
Escalator inclination angle - accurate answers-30 degrees Max, 1 degree
tolerance
Escalator brake speed - accurate answers-3 ft/sect
Escalator Governor switch - accurate answers-Not to exceed 140 percent
Escalator step level switch - accurate answers-Activates at 1/8" of sag
handrail speed switch - accurate answers-Alarm at 15% overspend, stops
after 2 seconds
Moving walk width - accurate answers-22"
Moving walk belt alignment - accurate answers-Detect 3/8 deviation
Platform Lift floor area - accurate answers-less than 12 sq ft
Platform lift capacity - accurate answers-750 lbs
Platform lift Speed - accurate answers-30 ft/min max
, Platform Lift Door Zone - accurate answers-within 3 inches of landing. Door
locking device prevents opening from more than 2 inches
Platform Lift Running Clearance - accurate answers-3/8-3/4
Platform/Chair Lift obstruction sensor actuation force - accurate answers-15
lb actuation force, 4 lbs (platform)
Single Speed AC Induction Motor qualities - accurate answers-low cost,
inaccurate landings, runs at slightly below synchronous speed, has stator and
rotor.
DC Brake BR resistor - accurate answers-Connected in series, controls how
fast the brake picks
Brake BD resistor - accurate answers-connected in parallel, controls how fast
the break drops. More resistance = faster brake drop. Less resistance =
slower/softer drop
Compounding - accurate answers-Adjustments made to series field with GSH
resistor connected in parallel with field. SF relay contacts used for fine
adjustment
Interpoles - accurate answers-Reduce commutator arcing,
Neutral Plane - accurate answers-when conductor is not cutting the magnetic
lines of flux and is not conducting
Suicide Circuit - accurate answers-Reverses Generator Self Excited (Shunt)
Field to kill all remaining residual magnetism when car stops
Phase relationship Inductive Circuit - accurate answers-Current lags behind
voltage 90 degrees
Diode Barrier Voltage - accurate answers-External voltage necessary for
electrons to cross over depletion region (0.7V silicon) (0.3V germanium)
Emitter Current - accurate answers-Ie = Ib + Ic. Equal sum of base and
collector current
