1. The__________ is the accepted standard in the US for safety installing and
maintaining electrical systems and equipment - ANSWER✓ NEC
2. Which of the following is not a basic rule of electrical safety? - ANSWER✓
Always work by yourself
3. Who should remove a lockout/tagout - ANSWER✓ Only the person who
installed it Types of electrical control systems - ANSWER✓ Manual,
automatic, and semi-automatic systems.
4. Control process steps - ANSWER✓ Input → Logic → Output.
5. Ladder diagram interpretation - ANSWER✓ Understand rungs, logic
elements, and power flow left to right.
6. Rules of drawing a ladder diagram - ANSWER✓ Include power rails, left-
to-right logic, one output per rung, label components, no crossings, logical
sequence.
,7. Elements of control logic - ANSWER✓ AND, OR, NOT, NOR, NAND, and
memory logic.
8. Control circuit design - ANSWER✓ Translate process needs into ladder
logic and validate operation.
9. Control relay operation - ANSWER✓ Recognize how energizing the coil
changes contact states.

23. Two methods of controlling multiple outputs at the same time are 1) by
branching the outputs, and 2) by placing each output on a separate rung and
using multiple input instructions with the same ___________. - ANSWER✓
Tags
24. The five types of numbering systems commonly used by PLCs are: decimal,
binary, BCD, octal and _____________. - ANSWER✓ Hexadecimal
25. One application of a(n) ___________ instruction is to control the
simultaneous start and stop of several outputs. - ANSWER✓ Internal output
26. PLC seal-in logic works by using a second XIC instruction that is connected
in ___________with the XIC instruction which turns on the output. -
