OVERVIEW OF OPERATING MODES

Operation modes in the basic Model 4000C system are:
 Learn
 Test
 Assembly
 Identification

Learn Mode

Learning loads the Dynamic Memory with a wire list for use in comparison against detected
continuities of assemblies under test. With the basic system, learning can be done in two
ways:

Learn from Known Good

In this learning procedure, a "known good" assembly (wiring harness, for example) is
scanned for existing continuities, and the resultant continuity data is stored in the Dynamic
Memory. This new wire list will write over (destroying) any program residing in the
memory.

Learn from Floppy Disk

Continuity data may be loaded into the Dynamic Memory by reading a previously saved
program from disk. This new program will write over (thus destroying) any program
residing in the memory. Programs may be saved and loaded from disk using ether the
Control Head switches or commands entered from a keyboard terminal.

Test Mode

In this mode, one complete scan is performed on the circuit under test. If the scanned
configuration compares exactly with the "learned" configuration in memory, the test is
successful. If an error is encountered, the points in error are displayed, along with an
indication of whether the error is an "open" or a "short."

Assembly Mode

During assembly, body conductance is employed to locate wires quickly and easily and
provides termination locations to the operator.

Random Build

In this mode body conductance identifies the wire touched by the operator and verifies
proper termination. If a lamp driver is part of the system and lamp driver data has been
programmed, the associated lamps can aid in providing termination and routing locations.

Sequential Build

Sequential build is used when a specific assembly sequence must be followed. The Model
4000C will display the next FROM/TO points to be assembled.
