IMPORTANT SAFETY INFORMATION AND PRECAUTIONS
Mn

Proper safety and repair is important to the safe. reliable operation of this unit. service should be done by qualified personne 1 only. This rna intenance manua I desc [i bes procedures rec-ommended by the manufacturer as effective methods of servicing
the uni t.
Some of these procedures require the use of specially designed tools.
For proper maintenance and safety.
these specially designed tools should be used as recommended.
l.'he procedures in this maintenance manual and labels on the
unit contain warnings and cautions which must be carefully read
and observed in order to minimize or eliminate the risk of personal injury.
The warnings point out conditions or practices
that are potentially hazardous to maintenance personnel.
The cautions point out practices which. if disregarded. could damage the unit and make it unsafe for use.
For the safety of maintenance and operating personnel. the following precautions must be observed:
•

Perform all maintenance by following the procedures given
in this manual and using only CDC/MPI replacement parts.

•

Read and observe all cautions and warnings
the procedures and labeled on the unit.

•

Use the special tools called out in the maintenance procedures.

•

Observe
nance.

•

Use caution when troubleshooting a unit that has voltages
present.
Remove power from unit before servicing or replacing components.

•

Wear safety glasses when servicing units.

•

Wear safety shoes when removing or
ponents.

It is also important to understand that these warnings and cautions are not exhaustive.
The manufacturer could not possibly
know. evaluate and advise maintenance personnel of all conceivable ways in which maintenance might be performed or the 'possible risk of each maintenance technique. Consequently. the manufacturer has not completed any such broad evaluation.
Thus.
any persons who use any non-approved maintenance procedure or
tool must first satisfy themselves that neither their safety
nor the unit performance will be jeopardized by the maintenance
techniques they select.

INTRODUCTION

This section contains the logic diagrams and an explanation of
the diagram conventions.
The diagram conventions, along with
the microcircuit manuals, provide the necessary informa tion to
understand and use the diagrams. The diagram conventions are:
• Symbology
• Abbreviations
• Logic Levels
• Signal Names
• Logic Arrangement
• Intersheet References
SYMBOLOGY
GENERAL

The diagrams contain a modified version of ANSI standard Y32.l4
logic symbology (see figure 1-1).
The logic symbols for integrated circuits contain a qualifying symbol, an element identifier, and a location code.

QUALIFYING (FUNCTION) SYMBOL

The qualifying symbol denotes the basic operation being performed by the integrated circuit.
Refer to the microcircuits
manual for an explariation of the qualifying symbols used in the
diagrams.
ELEMENT IDENTIFIER

The second line of any symbol contains the vendor/element identif ier.
This number identif ies the integrated circui t type.
Refer to the microcircuits manuals for an explanation of the
element identifiers used in the diagrams.
LOCATION CODE

The location code identifies the location of each component on
the circuit board.
The location code is a four-character XXYY
designation related to an X-Y grid defined on the edges of the
circuit board.
TO avoid confusion, the "XX" characters are
alpha-numeric and the "YY" characters are numeric.
Figure 1-2
shows a circuit board with a component at location code B622,
which is the intersection of grid lines B6 (X) and 22 (Y).

ABBREVIATIONS
Standard abbreviations from ANSI Yl.l are used whenever possible. Refer to the list of abbreviations contained in the front
ma tter for a definition of all abbreviations used in the diagrams.

LOGIC LEVELS
Three types of logic are used in the drives that this manual
applies to:
TTL logic, ECL logic, and CMOS logic.
Logic levels for the three types are shown in table 1-1. Different circuit configurations and temperatures may result in legitimate
readings that fall outside of the typical range.
Such readings
should be suspect only in the event of problems.

*Measuring a TTL open collector voltage may result in a

SIGNAL NAMES
Input and output signals are labeled to reflect their particular function.
If an output signal has no connection, and
therefore no function, it is labelled "NC" to indicate no connection. The polarity (logical state) of a signal is identified by a plus or minus sign before the signal name. A plus sign
before a signal name indicates that the signal is active when
the log ic level is high or in a logical "1" state.
A minus
sign before a signal name indicates that the signal is active
when the logic level is low or in a logical "0" state.
Refer
to the discussion on logic levels.

LOGIC ARRANGEMENT
Logic diagrams for the drive consist of overall block diagrams
and independent diagram sets for the interlocks, the detachable
cables, and the circuit boards. The diagram sets are presented
in the order given in table 1-2.
Refer to figure 1-3 for the
location of the circuit boards in the drive.
Each diagram set consists of one or more sheets with each sheet
identified by the sheet number which appears in the lower
right-hand corner of the page.
The first sheet in each set,
the cover sheet, is described in the following paragraph.

LOGIC DIAGRAM COVER SHEETS

The logic diagram cover sheet is the first sheet of each logic
set.
It contains power· and ground connections. and lists unused logic elements.
CIRCUIT BOARD TYPE

The circuit board type designation is shown on sheet 1 in the
title block.

INTERSHEET REFERENCES
Each logic diagram is assigned a four-digit cross-reference
number and a two-digit sheet number.
The first two digits of
the cross-reference number indicate the assigned set number,
and the last two digits indicate the sheet number within that
set.
Table 1-2 lists the cross-reference number for each logic
diagram set.
The following paragraphs discuss how to trace
signals from one point to another in the diagrams and refer to
both the sheet numbers and the cross-reference numbers.
The procedure for tracing signals in the logic diagrams depends
on whether the signal path continues on the same sheet, on
another sheet in the same logic set, or on a sheet in a different logic set. These three cases are symbolized differently in
the log ic (see figure 1-4) and are discussed separately in the
following paragraphs.
When a log ic signal is continued on the same sheet but cannot
be shown in series, "line of sight" arrows along with a letter
within a circle are used to indicate signal origin and destination.
When a logic signal is continued on another sheet of the same
logic set, that sheet number appears next to a hexagon containing a designating letter. This same letter is then shown where
the signal is continued.
When a signal is continued on a sheet of another logic set, it
follows a path through a cable from one circuit board to another.
Each sheet of logic which has signals coming from or going
to other circuit boards is accompanied by a Logic Cross Reference Information sheet, printed on the page facing the logic
sheet.
Logic Cross Reference Information lists all signal inputs and signal outputs in the order they appear on the log ic
sheet.
Each signal input listing includes the cross-reference
number of the logic sheet where the signal originates and the
connector and pin number for the signal origin.
Each signal
output listing includes the crossreference number of the logic
sheet where the signal goes and the connector and pin number
for the signal destination.
Each logic sheet is linked to its associated Logic Cross Reference Information sheet by the connector and pin symbols that
are duplicated on both sheets.
For instance, if a logic sheet
shows a signal enter ing the board on pin 1 of connector Jl4,
then the Logic Cross Reference Information sheet has thefollowing entry under Signal Inputs:
