UNIT OBJECTIVE
At the completion of this unit, you will be able to set up the F.A.C.E.T. system by using standard
lab procedures.

UNIT FUNDAMENTALS

The first course in the F.A.C.E.T. system, or the Fault Assisted Circuits for Electronics Training
system, consists of a base unit and a plug-in board of dc circuits called DC FUNDAMENTALS.

The base unit has built-in variable +10 Vdc and -10 Vdc regulated power supplies.

DC Fundamentals Unit 1 – Trainer Familiarization

Additional protective circuitswithin the base unit guard against over voltage, over current, and
reverse voltage in any circuit board; connected to the base unit.

Circuit boards are inserted into the base unit through the use of a Zero Insertion Force (ZIF)
connector.

When open, the ZIF connector allows circuit boards to be inserted without any friction.

When closed, the ZIF connector provides power and other electrical signals to the circuit board.
