UHF Analog Driver/Transmitter Chapter 1, Introduction

Chapter 1

Introduction

This manual explains the installation,
setup, alignment, and maintenance
procedures for the Innovator LX Series
UHF analog modular driver/transmitter.
It is important that you read all of the
instructions, especially the safety
information in this chapter, before you
begin to install or operate the unit.

1.1 Manual Overview

This instruction manual is divided into
five chapters and supporting appendices.
Chapter 1, Introduction, contains
information on the assembly numbering
system used in the manual, safety,
maintenance, return procedures, and
warranties. The second chapter describes
the driver/transmitter and includes
discussions on system control and status
indicators and remote control
connections. Chapter 3 explains how to
unpack, install, setup, and operate the
driver/transmitter. Chapter 4 contains
circuit-level descriptions for boards and
board-level components in the
driver/transmitter. Chapter 5, Detailed
Alignment Procedures, provides
information on adjusting the system
assemblies for optimal operation. The
appendices contain assembly and
subassembly drawings and parts lists,
and system specifications.

1.2 Assembly Designators

Axcera has assigned assembly numbers,
such as Ax (x=1,2,3…), to all assemblies,
modules, and boards that are referenced
in the text of this manual and shown on
the block diagrams and interconnect
drawings provided in the appendices.
These supporting documents are
arranged in increasing numerical order in
the appendices. Section titles in the text
for assembly or module descriptions or
alignment procedures contain the
associated part number(s) and the

relevant appendix that contains the
drawings for that item.

1.3 Safety

The UHF drivers and transmitters
manufactured by Axcera are designed to
be easy to use and repair while providing
protection from electrical and mechanical
hazards. Listed throughout the manual
are notes, cautions, and warnings
concerning possible safety hazards that
may be encountered while operating or
servicing the driver/transmitter. Please
review these warnings and familiarize
yourself with the operation and servicing
procedures before working on the
driver/transmitter.

Read All Instructions – All of the
operating and safety instructions should
be read and understood before operating
this equipment.

Retain Manuals – The manuals for the
driver/transmitter should be retained at
the transmitter site for future reference.
We provide two sets of manuals for this
purpose; one set can be left at the office
while one set can be kept at the site.

Heed all Notes, Warnings, and
Cautions – All of the notes, warnings,

and cautions listed in this safety section
and throughout the manual must be
followed.

Follow Instructions – All of the
operating and use instructions for the
driver/transmitter should be followed.

Cleaning – Unplug or otherwise
disconnect all power from the equipment
before cleaning. Do not use liquid or
aerosol cleaners. Use a damp cloth for
cleaning.

Ventilation – Openings in the cabinets
and module front panels are provided for

LX Series, Rev. 0 1-1

UHF Analog Driver/Transmitter Chapter 1, Introduction

ventilation. To ensure the reliable
operation of the driver/transmitter, and
to protect the unit from overheating,
these openings must not be blocked.

Servicing – Do not attempt to service
this product yourself until becoming
familiar with the equipment. If in doubt,
refer all servicing questions to qualified
Axcera service personnel.

Replacement Parts – When
replacement parts are used, be sure that
the parts have the same functional and
performance characteristics as the
original part. Unauthorized substitutions
may result in fire, electric shock, or other
hazards. Please contact the Axcera
Technical Service Department if you have
any questions regarding service or
replacement parts.

1.4 Maintenance

The Innovator LX Series
Driver/Transmitter is designed with
components that require little or no
periodic maintenance except for the
routine cleaning of the fans and the front
panels of the modules.

The amount of time between cleanings
depends on the conditions within the
transmitter room. While the electronics
have been designed to function even if
covered with dust, a heavy buildup of
dust, dirt, or insects will affect the
cooling of the components. This could
lead to a thermal shutdown or the
premature failure of the affected module.

When the front panels of the modules
become dust covered, the top covers
should be taken off and any accumulated
foreign material should be removed. A
vacuum cleaner, utilizing a small, wand­type attachment, is an excellent way to
suction out the dirt. Alcohol and other
cleaning agents should not be used
unless you are certain that the solvents
will not damage components or the silk­screened markings on the modules and
boards. Water-based cleaners can be

used, but do not saturate the
components. The fans and heatsinks
should be cleaned of all dust or dirt to
permit the free flow of air for cooling
purposes.

It is recommended that the operating
parameters of the driver/transmitter be
recorded from the LEDs on the modules
and the LCD system metering on the
control/monitoring module at least once
a month. It is suggested that this data be
retained in a rugged folder or envelope.

1.5 Material Return Procedure

To insure the efficient handling of
equipment or components that have been
returned for repair, Axcera requests that
each returned item be accompanied by a
Material Return Authorization Number
(MRA#).

An MRA# can be obtained from any
Axcera Field Service Engineer by
contacting the Axcera Field Service
Department at [phone] or by fax
at [phone]. This procedure
applies to all items sent to the Field
Service Department regardless of
whether the item was originally
manufactured by Axcera.

When equipment is sent to the field on
loan, an MRA# is included with the unit.
The MRA# is intended to be used when
the unit is returned to Axcera. In
addition, all shipping material should be
retained for the return of the unit to
Axcera.

Replacement assemblies are also sent
with an MRA# to allow for the proper
routing of the exchanged hardware.
Failure to close out this type of MRA# will
normally result in the customer being
invoiced for the value of the loaner item
or the exchange assembly.

When shipping an item to Axcera, please
include the MRA# on the packing list and
on the shipping container. The packing
slip should also include contact

information and a brief description of why
the unit is being returned.

Please forward all MRA items to:

AXCERA, LLC
103 Freedom Drive
P.O. Box 525
Lawrence, PA 15055-0525 USA

procedure, call the Axcera Field Service
