EQUIPMENT IDENTIFICATION
An equipment number
is
assigned to each drive
to identify its configuration.
This provides
a systematic method of identifying, account-
ing, and controlling changes that affect
drive logic and mechanical components.
The equipment configuration is identified by
a nameplate attached to the frame at the
back of the drive.
The nameplate.is visible
with the logic chassis open.
The Equipment
Identification Number will be similar to the
following:

Code
The Equipment Identifier indicates the basic
function of the unit.
This number will
be
BR3C9 on all units for which this series of
manuals have been prepared.
The
Type
Identifier indicates a non-inter-
changeable difference in equipments that
affects the interface.
The term "Mod" is
sometimes· used interchangeably with "Type
Identifier" •
The Series Code Changes with each non-inter-
changeable change within the equipment.

Drives with different series codes are fully
interchangeable at the system level: however,
not all of their electrical or mechanical
components may be interchangeable.
Series
codes are changed by Engineering Change
Order (ECO) only at the factory.
Other changes are accomplished by Field
Change Order (FCO).
These changes may be
installed either at the factory or by field
personnel.
FCO changes are indicated by an
entry on the FCO Log that accompanies each
machine.
It is important that this log be
kept current by the person installing each
FCC.
Unless otherwise specified, all theory, pro-
cedures, and diagrams in these manuals apply
to all units.
Exceptions are noted where
applicable.
Manuals accompanying unit shipments from
the manufacturer match the configuration of
those units.
Subsequent manual changes are
controlled by the Revision Record sheet
behind
the
title page of every manual.
This
sheet identifies the Series Code and FCC
effectivity of manual changes.
If mainte-
nance will be performed using a manual
other than the manual supplied with each
drive, verify that the manual and drive
configurations match.
