Neiep review 1
** A client does now not want an Escape Hatch on his residential elevator. Under what
situations is this prison? - ANS-Manual Operation need to be provided (850)
** Car is walking typically however the buzzer will no longer shut off. Why? - ANS-EHP 3/2
shorted. (Fire Service)
** How must a nine lead 480/240 motor be stressed out for low voltage placing? - ANS-L1 (1,7).
L2 (2,eight). L3 (three,9). (4,5,6)
** If you find a broken or lacking barricade, what do you do? - ANS-Write up a proper inspection
request
+120v___________o----o______R2______A_____R1_____GRD - ANS-
1 gal equals how many cubic inches? - ANS-231
2nd ground PI illuminates then quickly extinguishes. Why? - ANS-XI 4and6
49. How do you connect brackets to brick? - ANS-Inserts ¼" from the face of the brick, inward
102.How many gallons had to run a four" plunger 25 feet? - ANS-16.Three gal. Note: V= A(H)
(ought to convert to inches)
A 300ohm resistor burns out, however you do not have another one. How can you're making
one? - ANS-600ohm resistors in parallel is 300ohms. Resistance is 1/2 of highest resistor in
parallel circuit.
Three 225ohm resistors in parallel is 750hms.
A 480 vac step down 240 vac transformer is hooked up to a 3 segment rectifier. What could be
the output? - ANS-320 VDC
A vehicle journeying in the hoistway always stops on the same spot and blows a fuse. What
reasons this? - ANS-Traveling cable has a reduce/exposed wire or a quick
A car weighs 2500 lbs with a capacity of 2500 lbs. The CWT is weighted at forty%. How a whole
lot is the motor lifting at 100% load? - ANS-1500 lbs. 2500x40%=one thousand lbs,
2500+1000=3500, 5000-3500= 1500lbs
, A car with a selective collective controller is transferring to the lobby to pick out a name. An up
call is put in at the second one ground. What occurs? - ANS-Call is bypassed til the auto is
transferring within the up route.
A contractor desires to raise the auto velocity from 100fpm to 125fpm, it currently has a 12"
sheave. What sheave is required? - ANS-Diam=12" 12/four=three" 25fpm=3" 100fpm + 25fpm=
12"+three"= 15" sheave
A force of 500lbs is applied to a plunger with an area of 25 squarein, what is the system strain?
- ANS-200 psi. Note: 5000lbs/ 25 sq.In= 200psi P=F/A
A hydro runs up with out a load, but will now not run with a full load. What is the issue? -
ANS-The comfort valve is ready too low
A motor needs a sleeve bearing changed. What sort of bearing will you want? - ANS-Friction
Bearing (420)
A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage or resistance.
What have to you do? - ANS-Replace it with a larger MOV
A vertical platform elevate has a clearance of 1in. How lots will it should be moved to meet
code? - ANS-
At what distance from closed does the gate switch function? - ANS-2"
At what velocity should the governor switch contact be set to open? - ANS-ninety - ninety five%
of Governor tripping speed.
Car doors are dragging at the sill. How high need to they be raised to be code compliant? -
ANS-¼"
Car is loaded with a hundred twenty five% and sinks. Why? - ANS-Slipping via the smash
Car will now not journey to2nd floor with out a 3rd ground name, and will now not move down
from third without a 2nd ground call. What is the problem? - ANS-2FI4/6
During production the omega CWT rails were damaged. Why? - ANS-Overtightened from rail
bracket. (215)
During construction you land an escalator, however it's miles 10mm too low. What is incorrect? -
ANS-Pit is to deep or column mark is off.(825)
Given a generator runs at six hundred RPM and has four poles is the output frequency ? -
ANS-600/60 sec=10x2=20Hz
