Non Interference timer circuit - ANS✔✔--You are called to a building with a pressure
button control freight, The problem is when you run the car to the floor, before you can open
hall doors a person on another floor can call the car and have it run.
What circuit do you look at?
725 Pg 3
Damage the stator or rotor - ANS✔✔--While testing for a locked rotor condition, what
would happen to the motor if the test was carried out to long?
,435 Pg 13
Group Dispatch - ANS✔✔--In an elevator system of 2 or more cars, what is needed to
coordinate the movement and the hall dispatch calls?
720 Pg 19
A Latching relay: Used for call registration,direction selection or as selector relays
Two types are: Set/Rest are electrical and Mechanical Latching relays
Need to know latching relay symbol, Its a box with shaded triangle in lower right hand
corner. - ANS✔✔--Which relay do you need to Order
710 Pg, 7
RPM = 60 ∙ ƒ ÷ P÷2 =
Step 1. 60 x Frequency (Hz.) =
Step 2. Poles ÷ 2 =
Take answer 1 and ÷ by answer 2 = - ANS✔✔--Know the formula for RPM
435 Pg. 5
If you are referring to a megohm meter, it is a test of the insulation properties of such things
as electric wiring, motor windings and high power antenna mounts.
,We use a "megger" or "meg out" electrical wiring and equipment to see if it is shorted to
ground or the frame in any way.
The megger uses much higher voltages to check resistance than a normal Volt-ohm meter.
Minimum resistance is 1 Meg Ohm - ANS✔✔--Know what a Megger is and what it does
636 Pg. 13
(1) A parallel connection. (2) A resistive element placed across the terminals of an armature
to bypass a portion of the current. (3) A flexible electrical conductor designed to conduct
current around the mechanical joint between two conductors. (4) The resistive element
(Usually of very low resistance) used in parallel with a DC ammeter movement to bypass a
calibrated portion of the total circuit current. - ANS✔✔--Shunt Overloads
425 All Pages
Bad Ground - ANS✔✔--You are using a Temp Run Box and you get shocked! Why!
520 Pg. 4
The bridle hitch can consist of two,three, or four single hitches (fig. 3-22), used together to
form a bridle hitch for hoisting an object
A sling with two legs used to lift a 1,000 pound object will have 500 pounds of the load on
each leg when the sling angle is 90 degrees. The load stress on each leg increases as the
angle decreases; and if the sling angle was 30 degrees lifting the same 1,000 pound object,
the load will be 1,000 pounds on each leg. Try to keep all sling angles greater than 45
, degrees; sling angles approaching 30 degrees are considered extremely hazardous and
must be avoided at all cost. - ANS✔✔--Bridal Hitch
128 Pg 17
Scaffolding should be tied to the structure using
#9 wire or tie-in devices. The first vertical tie
should be at the maximum height of 4 times the
narrowest base dimension. Additional ties are not
to exceed 26' vertically. Maximum horizontal
distance between ties is not to exceed 30'. - ANS✔✔--Scaffolding, You have 32' of rise,
you are using 3x5 scaffolding. Where will the tie off points be ?
140 PG. 287-288
240 Pg. 14
Note: We do not use wire smaller than #20 in travelling cables and #24 outside travelers.
Largest wires are feeders to Hoist /Pump motor
We always have 10 % spares
10% of 52 = 5.2
On a calculator Multiply the percent 10 by the number you have and ÷ by 100
10 X 52 ÷ 100 = 5.2 - ANS✔✔--Pulling Spare Wires (Example) 10% of 52 Wires
515 Pg.26
