QUESTION: A MOV (Metal Oxide Varistor) burns out. You replace it,
but cannot read voltage or resistance. What should you do?
Ans: Replace it with a larger MOV
QUESTION: On a Ward-Leonard circuit the break is set, but the
motor is trying to slip through the break. What is the issue?

QUESTION: A hydro runs up with no load, but will not run with a full
load. What is the issue?
Ans: The relief valve is set too low
QUESTION: Runby for a 1:1 hits the CWT buffer 4" below the top
landing. CWT runby should be set at 18". How much should the
ropes be shortened?
Ans: 22"
QUESTION: You need to work on a freight door retiring cam, you
LOTO the main line but there is still power on the cam. What circuit
is still hot?

Ans: Adjust Tie Downs and Wall Ties
QUESTION: Working pressure on a Hydro is 400psi. What is the
maximum relief valve setting?
Ans: 400psi x 150%= 600psi
QUESTION: What must be installed on a false car before operation?
Ans: Spring Loaded Safeties.
QUESTION: There is slight arcing between the brush and
commutator. What action must be taken?
Ans: None.
Heavy arcing=Light brush pressure. Heavy bush pressure=mechanical wear
QUESTION: If rigging gear is roped 3:1 and a BEAM CLAMP is used to
lift a 6,000lb load. What is the beam capacity?
Ans: 18,000lbs. Beam capacity is cut in half with use of clamp, when rigging all
blocks, rope, and clamps will be Equal to the lowest load rating

QUESTION: How much resistance is measured over a normally closed
switch?
Ans: 1.2ohms. should be zero, but will never be that low
QUESTION: A car traveling in the hoistway always stops at the same
spot and blows a fuse. What causes this?
Ans: Traveling cable has a cut/exposed wire or a short
QUESTION: How is a class 1 yearly buffer test preformed?
Ans: Car at bottom landing and on inspection, jump out direction and final
limits. With pit clear, run down to compress buffers, buffers should fully extend
within 90 seconds.
5yr: Full load Full speed
CWT: Full speed Empty
QUESTION: How many strain supports are required on a 350ft
raceway?
Ans: 4. 1 every 100ft
