Chapter 3 Self Test Flashcards
(215) 2. What are the three primary areas you may deal with ESDS items?
Cabling/connectors, LRUs, and circuit cards
(215) 1. What TO covers the framework of control for ESD sensitive devices?
00-25-234
(215) 3. What kind of indicator would clue you in to the existence of ESDS components?
ESD markings
(215) 4. What does this symbol (ESD) prepare you for when it appears before a maintenance step in the TO?
This lets you know that you will be woking with an ESDS item and that you need to use proper ESD controls to accomplish the maintenance actions.
(215) 5. Where must ESD prevention and awareness training be documented?
Training results must be documented in your personal training records.
(215) 6. What is the single most important item for effective static control?
The wrist strap
(215) 7. What must be installed to ensure an electronic drawer’s internal components are protected by an effective Faraday Cage?
Conductive dust caps
(215) 8. At an LF or LCF, what is the resistance reading you are looking for when measuring between the facility ground point and the portable work station’s CPGS?
Less than 10 ohms
(215) 9. Which type of packaging material is the first layer of material to cover ESDS components and is typically used in conjunction with other types of packaging?
Type II
(215) 10. What are the three classifications of ESDS failures and which one is usually the easiest to detect?
Catastrophic, intermittent, and latent
(216) 1. Where in the 21M-LGM30G-2-1-X should you begin looking into a fault?
Fault index section
(216) 3. Which fault series are only associated with the LF?
1000 series
(216) 4. Where would you look to find a list of cables associated with a fault number?
The list of cables/power and signal distribution unit (PSDU) to fault number
(216) 5. Where would LF and MAF post maintenance requirements be located?
Foldouts
(217) 1. In what state are circuits generally portrayed on a diagram?
De-energized
(217) 2. What are used by diagram authors to include critical information in a diagram?
Legends
(218) 1. What are two things you can do to make tracing circuits on a diagram easier for troubleshooting?
Extract (make a simple drawing) only of the specific circuit and color code the circuit for easy identification and clear understanding of the particular circuit.
(218) 2. When extracting a circuit, what does a schematic show you?
Where you are, where you are going, and where you came from
(218) 3. How should you label electrical contacts when extracting circuits?
Normally open (N/O) or Normally closed (N/C)
(219) 1. What steps would you take if you were replacing a maintenance team to continue troubleshooting a fault?
Verify that the system or circuits have been returned to their operational configuration.
(219) 2. What is the definition of electrical trouble shooting?
A step-by-step procedure of analyzing, locating, and correcting electrical malfunctions
(220) 1. What are the most common types of electrical malfunctions?
Opens, shorts, grounds, and low power
(220) 3. On what type of component would you expect more resistance in one direction?
Diodes
(220) 4. How would you check the resistance across a relay’s contacts?
In order to measure contactor resistance, you must manually close the relay contacts and measure between the input and output contactor terminals.
