Important Change Notification
This document supersedes both the TCF–10B Frequency-Programmable Frequency-Shift Carrier
Transmitter/Receiver System Manual CF44–VER01, last printed in April 1996, and the Addendum to
CF44–VER01, printed December 10, 1996. The following list shows the most recent publication date for
each chapter. Publication dates in bold type indicate changes to that chapter since the previous publica-
tion. For these chapters, the specific pages that have changed are listed for easy reference. Note that only
significant changes, i.e., those changes which affect the technical use and understanding of the document
and the TCF–10B equipment, are reported. Changes in format, typographical corrections, minor word
changes, etc. are not reported. Note also that in some cases text and graphics may have flowed to a
different page than in the previous publication due to formatting or other changes. The page numbers
below show the current pages on which the reported changes appear.
Each reported change is identified in the document by a change bar placed in the margin to its immediate
left, just like the one on this page.

TCF–10B System Manual
e recommend that you become acquainted with the information in this manual before ener-
gizing your TCF–10B system. Failure to do so may result in injury to personnel or damage to
the equipment, and may affect the equipment warranty. If you mount the carrier set in a cabinet,
it must be bolted to the floor or otherwise secured before you swing out the equipment, to
prevent the installation from tipping over.
You should not remove or insert printed circuit modules while the TCF–10B is energized.
Failure to observe this precaution can result in undesired tripping output and can cause
component damage.
All integrated circuits used on the modules are sensitive to and can be damaged by the discharge
of static electricity. You should observe electrostatic discharge precautions when handling
modules or individual components.
PULSAR does not assume liability arising out of the application or use of any product or circuit
described herein. PULSAR reserves the right to make changes to any products herein to improve
reliability, function or design. Specifications and information herein are subject to change
without notice. All possible contingencies which may arise during installation, operation, or
maintenance, and all details and variations of this equipment do not purport to be covered by
these instructions. If you desire further information regarding a particular installation,
operation, or maintenance of equipment, please contact your local Pulsar Technologies, Inc.
representative.

Preface
Scope
This manual describes the functions and features of the TCF–10B Power Line Carrier Transmitter
Receiver. It is intended primarily for use by engineers and technicians involved in the installation,
alignment, operation, and maintenance of the TCF–10B.
Equipment Identification
The TCF–10B equipment is identified by the Catalog Number on the TCF–10B chassis nameplate. You
can decode the Catalog Number using the Catalog Number Table in Table 2-4 and Figure 2-15 (see
Chapter 2).
Production Changes
When engineering and production changes are made to the TCF–10B equipment, a revision notation (Sub
number) is reflected on the style number, related schematic diagram, and associated parts information. A
summary of all Sub numbers for the particular release is shown on the following page.
Warranty
Our standard warranty extends for either 18 months after the equipment is in-service or 24 months after
shipment, whichever comes first. For all repaired modules or advance replacements, the standard warranty
is 90 days or the remaining warranty time, whichever is longer. Damage clearly caused by improper appli-
cation, repair, or handling of the equipment will void the warranty.
Equipment Return & Repair Procedure
To return equipment for repair or replacement:
1. Call your PULSAR representative at 1–800–785–7274.
2. Request an RMA number for proper authorization and credit.
3. Carefully pack the equipment you are returning.
Repair work is done most satisfactorily at the factory. When returning any equipment, pack it in
the original shipping containers if possible. Be sure to use anti-static material when packing the
equipment. Any damage due to improperly packed items will be charged to the customer, even
when under warranty.
Pulsar Technologies, Inc. also makes available interchangeable parts to customers who are
equipped to do repair work. When ordering parts (components, modules, etc.), always give the
complete PULSAR style number(s).
4. Make sure you include your return address and the RMA number on the package.
5. Ship the package(s) to:

TCF–10B System Manual
Document Overview
The TCF–10B circuitry is divided into nine (9) standard modules. In addition, Voice Adapter, Electro-
mechanical, and Transfer Trip Test Unit modules are available as options. (See Chapter 7, Figure 7-1, for
a Functional Block Diagram.)
Chapter 1 provides the Product Description, which includes specifications; module circuit descriptions and
troubleshooting procedures are in Chapters 9 thru 19. Chapter 2 presents applications and related catalog
numbers for ordering purposes. The TCF–10B installation is described in Chapter 3, with maintenance
procedures in Chapter 8. Chapters 4, 5, and 6 identify test equipment, acceptance tests, and adjustment
procedures, respectively, while Chapter 7 describes the TCF–10B signal path (for use during testing).
Contents of Carrier Set
The TCF–10B carrier set includes the style numbers, listed below, with appropriate sub numbers repre-
senting revision levels. (To determine related style numbers, you may also refer to Figure 2-15.)
