Sequential Build (Seq Build) - Cablescan 4000C Instruction Manual

Model 4000C Instruction Manual
7. When the correct termination is made, the tone will sound and the display will show:
8. Touch each succeeding wire, in any order desired, and make terminations as in Steps 6
and 7 above.
9. An "F" will appear at the left of the display when the FROM point is touched, or a "T"
will appear when the TO point is touched. Also, as soon as either the FROM or TO point
is touched, an intermittent tone will sound. The tone and the "F" or "T" will be present
only while the point is being touched.
10. The displayed From/To point may be canceled by pressing either the RANDOM BUILD
key or the footswitch.
11. After all wires are assembled, press TEST to locate any shorts that may have been
created, and opens for unassembled circuits.

Sequential Build (Seq Build)

This is a recorded procedure that provides a specific assembly sequence for a specific
assembly, using a program generated using the Keyboard/CRT Terminal. The SEQ BUILD
mode requires use of the wrist strap to locate and identify displayed points, and the footswitch
to bypass sequence steps. A complete procedure is provided below. Once familiarized, the
user may refer to Figure 10. To select and use SEQ BUILD in building an assembly, proceed
as follows:
1. Load program into memory (refer to Loading a Program).
2. Attach wrist strap to arm, and plug wrist strap lead into PROBE receptacle on the control
head.
3. Plug footswitch lead into FOOTSWITCH jack on the rear panel.
4. Press SEQ BUILD; the Model 4000C will proceed to check each programmed continuity
according to the stored sequence.
5. If a proper termination is not found in one of the sequence steps, the sequencing will stop
and the FROM and TO points will be displayed.
6. An "F" will appear at the left of the display when the FROM point is touched, or a "T"
will appear when the TO point is touched, and an intermittent tone will sound. The tone
and the "F" or "T" will be present only while the points are touched.
7. The Model 4000C will then test for the remaining stored sequence steps until the next
open circuit in the sequence is found.
8. Steps may be bypassed by pressing the footswitch once for each step to be bypassed, or
by pressing SEQ BUILD.
9. When the last sequence step has been tested, the display will show "OK." A test of the
assembly may now be performed to find any shorts or opens that may have developed
during assembly.
