How would you connect an ohm-meter to check load resistance? - ✔✔✔
Correct Answer > Black to common Red to V ohm Switch at Ohm.
No power, take one lead off, connect in parallel Analog needs to be
Zeroed 1 st
What must be installed on a false car before operation? - ✔✔✔ Correct
Answer > Spring Loaded Safeties.
There is slight arcing between the brush and commutator. What action
must be taken? - ✔✔✔ Correct Answer > None.
Heavy arcing=Light brush pressure. Heavy bush pressure=mechanical
wear
,Exciter voltage comes from what source? - ✔✔✔ Correct Answer > Generator
Your pulling 15 #14awg 27 #16awg 57 #18awg wires. How many spares
needed? - ✔✔✔ Correct Answer > 2 #14
3 #16
6 #18
10% spares required
A contractor wants to raise the car speed from 100fpm to 125fpm, it
currently has a 12" sheave. What sheave is required? - ✔✔✔ Correct Answer
> Diam=12" 12/4=3" 25fpm=3" 100fpm + 25fpm= 12"+3"= 15" sheave
A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot
read voltage or resistance. What should you do? - ✔✔✔ Correct Answer >
Replace it with a larger MOV
On a Ward-Leonard circuit the break is set, but the motor is trying to
slip through the break. What is the issue? - ✔✔✔ Correct Answer > Suicide
Circuit
,You have an old DC motor and are adding an SCR drive, what do you do
to the interpoles? - ✔✔✔ Correct Answer > Leave the interpoles alone. When
adding a SCR drive to the generator, the series loop is removed, as are
the 3 resistors. Everything else remains the same
A hydro runs up with no load, but will not run with a full load. What is
the issue? - ✔✔✔ Correct Answer > The relief valve is set too low
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?
- ✔✔✔ Correct Answer > 22"
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? - ✔✔✔
Correct Answer > Door Operator Disconnect/ Main Line Disconnect
, The contractor requests that the vertical center of a Rack and Pinion
hoist be moved. How do you do this? - ✔✔✔ Correct Answer > Adjust Tie
Downs and Wall Ties
Working pressure on a Hydro is 400psi. What is the maximum relief
valve setting? - ✔✔✔ Correct Answer > 400psi x 150%= 600psi
If rigging gear is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb
load. What is the beam capacity? - ✔✔✔ Correct Answer > 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
How much resistance is measured over a normally closed switch? - ✔✔✔
Correct Answer > 1.2ohms. should be zero, but will never be that low
A car traveling in the hoistway always stops at the same spot and blows
a fuse. What causes this? - ✔✔✔ Correct Answer > Traveling cable has a
cut/exposed wire or a short
