Guide to Using Harris Parts List Information

The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index. The
example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of
materials table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the
Replaceable Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level
below the Transmitter and implies that they are used in the Transmitter. The Controller Board is indented one level
below the Control Cabinet so it will show up in the bill of material for the Control Cabinet. The tree structure of this
same index is shown to the right of the table and shows indentation level versus tree structure level.

Example of Replaceable Parts List Index and equivalent tree structure:

Replaceable Parts List Index Part Number Page

Table 7-1. Transmitter 994 9283 001 7-2
Table 7-2. Control Cabinet 992 9244 002 7-3
Table 7-3. Controller Board 992 8344 002 7-6
Table 7-4. PA Cabinet 992 9400 002 7-7
Table 7-5. PA Amplifier 994 7894 002 7-9
Table 7-6. PA Amplifier Board 992 7904 002 7-10
Table 7-7. Output Cabinet 992 9450 001 7-12

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that
part number starts. Inside the actual tables, four main headings are used:

• Table #-#. ITEM NAME - HARRIS PART NUMBER - this line gives the information that corresponds to the

• Replaceable Parts List Index entry;

• HARRIS P/N column gives the ten digit Harris part number (usually in ascending order);

• DESCRIPTION column gives a 25 character or less description of the part number;

• REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102, etc.)

that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the sche­matic) or 2) gives added information or further explanation (i.e., “Used for 208V operation only,” or “Used for HT
10LS only,” etc.).

Inside the individual tables some standard conventions are used:

• A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column means

that this item is used on or with C001 and is not the actual part number for C001.

• In the ten digit part numbers, if the last three numbers are 000, the item is a part that Harris has purchased and has

not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured by Harris
or is purchased from a vendor and modified for use in the Harris product.

• The first three digits of the ten digit part number tell which family the part number belongs to - for example, all elec-

trolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found to have
a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been modified in
some manner at the Harris factory and will therefore show up farther down into the individual parts list (because
each table is normally sorted in ascending order). Most Harris made or modified assemblies will have 9xx xxxx xxx
numbers associated with them.

The term “SEE HIGHER LEVEL BILL” in the description column implies that the reference designated part number
will show up in a bill that is higher in the tree structure. This is often the case for components that may be frequency
determinant or voltage determinant and are called out in a higher level bill structure that is more customer dependent
than the bill at a lower level.

1.2.3 Transmitter Control System

The transmitter uses a distributed architecture control system. This means that each
transmitter sub-system is responsible for its own monitoring and protection and
simply reports back to the Main Controller for display on the GUI (Graphical User
Interface) or to a remote interface. The heart of the system is the 376 Micro Module
which is used in all of the transmitter systems for control, monitoring and
protection. The Micro Module is used on each of the following controllers and sub­systems:

a. Main Controller Board - This board is responsible for transmitter control and

monitoring. However, with the distributed control architecture, it is not
directly responsible for protection of the individual transmitter components. It
merely gathers all status and fault data from the individual sub-systems and
reports that information to the operator. The Main Controller is responsible
for system level control (issues which effect multiple systems) since it is the
only part of the control system which can monitor the entire transmitter.

b. Module Controllers (1 in each module) - Responsible for protection and con-

trol of the PA Module. Report directly to the Main Controller Board.

c. RF Monitor Board - Responsible for cabinet VSWR protection and monitor-

ing of combiner reject loads. Reports directly to the Main Controller.

d. Power Supply Monitor Board - Responsible for control and monitoring of the

PA power supplies and distribution of the low voltage. Also responsible for
monitoring the cooling system including temperature, flow and leaks. Reports
directly to the Main Controller.

e. External I/O Board - Provides all customer interface connections including

parallel remote control and serial remote control. Reports directly to the Main
Controller.

1.2.3.1 Graphical User Interface

The front panel user interface is a 1/4 VGA, LCD touchscreen display. The
touchscreen display uses software buttons to monitor the transmitter. Hardware
buttons for the primary transmitter functions such as ON, OFF, RAISE and
LOWER are provided on the overlay panel next to the display.

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction

ATLAS Series™

1.2.3.2 Control System Communications

The control system uses a serial communications system called a CAN bus. CAN
stands for Controller Area Network. The CAN bus is a closed loop serial network
operated by the Main Controller Board. Each circuit board and module connected to
the CAN bus is considered a node and therefore has a specific address. This allows
the Main Controller to gather information from all parts of the transmitter and
display it on the GUI. One big advantage of the CAN bus is that it requires only 2
wires of the system control ribbon cable, eliminating a large amount of discrete
wiring which would otherwise be required.

For redundancy, the CAN bus is backed up by parallel, hardwired, control lines that
allow the transmitter to stay on the air even if the CAN bus fails. The parallel
control lines also provide the instantaneous OFF and RF MUTE commands
necessary for transmitter protection.

1.2.3.3 In-System Programming or ISP

The use of the CAN bus for communication between the various Micro Modules in
the transmitter also allows for easy updating of the software used in each transmitter
sub-system via a serial port connection to an external computer. This is referred to
as In-System Programming or ISP.

The real benefit of In-System Programming is that it allows any or all of the
transmitter software to be updated without removing or replacing any firmware ICs.
The Harris ISP program is provided on the CD-ROM accompanying this manual
along with all of the transmitter software as it shipped from the factory. The Harris
ISP program is easy to use and it only takes a few minutes to load or update
software.

NOTE:

Software does not need to be loaded into the transmitter unless new compo­nents are installed or an update is sent from Harris. The transmitter, as
shipped from the factory, is preloaded and ready to run.

1.2.3.4 Remote Control

The Atlas Series™ transmitter has the basic Discrete wired parallel remote control
with the standard connections for control, status and analogue monitoring. A
network interface will be available by mid year 2002, but this will be an optional
add-on deivce.

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction ATLAS Series™

1.2.4 PA Module

The Atlas Series™ PA Module utilises LDMOS amplifiers to produce up to 460W
average power output. Each module weighs approximately 20.5kg and can be un­plugged while the transmitter is running. A single cabinet Atlas Series™ transmitter
can have 1, 2, 3, 4, 6 or 8 PA modules to achieve the various power levels shown in
Table 1-1. The 2 cabinet version will have either 6 or 8 modules per cabinet. A
block diagram of the PA module is shown in Figure 1-4.

Each PA module consists of the following components:

a. PA Module Controller Board - Responsible for all monitoring and protection

of the module. Reports to the transmitter Main Controller via the CAN bus
but is also connected to the parallel control lines in case the CAN bus is not
operational.

b. Phase and Gain Board - Provides for module phase and gain adjustments to

minimise module combiner reject power. Also provides for cabinet phasing
for the 2 cabinet transmitters to minimise cabinet combiner reject power.

c. DC Distribution Board - Provides FET switching of the +32Vdc and sensing

of driver and pallet currents.

d. Pre-driver Pallet - Provides enough power to drive the 2 way splitter and the 2

driver pallets.

e. Two (2) LDMOS Driver Pallets - Provide enough power to drive the 4 way

splitters and the inputs to the power amplifier pallets.

f. Pallet Splitter and Combiner - Actually two 4-way splitters and one 8-way

combiner.

g. Eight (8) LDMOS Amplifier Pallets - When combined, they provide up to

460 watts of average power at the output of the module.

h. Liquid Cooled Cold Plate - Mounted directly to the 8 LDMOS power ampli-

fier pallets for cooling.

i. RF Output Directional Coupler - Samples both Forward and Reflected power

for metering, module ALC and module VSWR protection.

Each Atlas Series™ PA Module is a self-contained 460W transmitter (except for the
power supply) with its own internal control, monitoring and protection. The
modules only receive basic On/Off, Mute, Restart, Phase and Gain commands from
the transmitter control system. This means that each module will protect itself
without relying on the system controller.

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction

ATLAS Series™

1.2.4.1 Module Control

The primary method for control and monitoring of the PA Modules is by the serial
CAN (Controller Area Network) Bus. It is used for control, status and monitoring of
all PA Module parameters and for the reporting of Module faults. As a backup to
this serial control network, each PA Module has dedicated hardware control lines
for functions such as On, Off, Restart and RF Mute.

Figure 1-4 PA Module Block Diagram

1.2.5 Power Supplies

Up to four +32 Vdc power supplies are used to provide the DC voltage to the PA
modules within each PA cabinet. Each power supply provides power to two PA
modules. Module power supplies are designed to allow removal and insertion of one
unit while the remaining power supplies are operating. The control system in the PA
Cabinet is powered by a single low voltage power. A second (redundant) low
voltage power supply is optional.

Section 1 Introduction ATLAS Series™

1.2.6 Cooling System

The Atlas Series™ transmitter uses a 50/50 glycol liquid cooling system to remove
the majority of the heat away from the transmitter but also has cabinet flushing fans
to remove residual cabinet heat. A simplified block diagram of the liquid cooling
system is shown in Figure 1-6. A simplified diagram of the liquid cooling system
inside the transmitter cabinet is shown in Figure 1-7. The cooling system basically
consists of:

a. Cooling System Control Panel
b. Pump Module

c. Heat Exchanger

d. Transmitter Cold Plates

1.2.6.1 Cooling System Control Panel

The cooling system control panel controls the pump module and the heat exchanger
and is the interface to the transmitter control system. It uses very basic relay logic
for reliable operation. The cooling system control panel is connected to the External
I/O board in the Atlas Transmitter for monitoring and control. It also supplies ac
power to the pump module and the heat exchanger and interfaces the fault and status
information from these units to the transmitter.

The cooling system control panel, shown in Figure 1-5 below, has local controls on
the front which allow manual selection of pump A or optional pump B and selection
of Remote/Local control. It also has the following status indicators:

• Remote

• Local

• Interlock

• Fan A ON

• Fan B ON

• *Pump A ON

• *Pump B ON

• Pump A Preset

• Pump B Preset

• *Coolant Fault

• *Coolant Low

• Power

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction

ATLAS Series™

* Each of these status indications is also sent to the transmitter for display on the
GUI and via remote control.

When in Remote mode, the transmitter is responsible for control of the cooling
system, including ON/OFF, manual pump selection and automatic pump switching
in the case of a failure. Placing the control panel in Local mode allows manual
switching of the pumps using the pump select buttons on the cooling control panel.

The lower half of the control panel contains the ac isolation switch which
disconnects ac power from the pump module and heat exchanger as well as the
control circuitry in the control panel itself.

1.2.6.2 Pump Module

The pump module is a self-contained unit with a storage tank, pressure and
temperature gauges, a strainer filter and one pump or the optional dual pumps
operating in main/standby mode. The pump module is an open frame unit and is
meant to be installed inside the building (with a special option for outside
mounting). The control panel is separate from the pump module and should be
mounted near the transmitter (usually next to the transmitter disconnect panel).

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction ATLAS Series™

1.2.6.3 Heat Exchanger

The heat exchanger, which is usually installed outside, has 2 fans. The fans are
enabled whenever the pump module is activated, but temperature sensors determine
when the fans will actually start. The first one turns on when the coolant
temperature reaches 32oC with the second one turning on at 38oC.

1.2.6.4 Transmitter Cold Plates

Each PA Module has an attached liquid cooled cold plate which connects to the
cooling system with flexible hoses and quick release connectors. There is also a
separate cold plate mounted inside the transmitter cabinet to which all of the
combiner reject loads are attached. See Figure 1-7.

Section 1 Introduction

ATLAS Series™

1.2.7 V-XCAST™ Exciter

The ITIS V-XCAST™ COFDM (Coded Orthogonal Frequency Division Multiplex)
exciter is used with the Atlas Series™ transmitter. This exciter is described in a
separate instruction book. A second hot standby exciter/driver and drive chain
switcher is available as an option. The exciter is controlled and configured using an
RS-232 serial connection. Software is provided with the exciter. A serial diagnostic
and monitoring port is also provided.

The COFDM exciter V-XCAST is a fully compliant DVB-T (Digital Video
Broadcast - Terrestrial) exciter and up-converter supporting both 2K and 8K
operations, specifically designed for commercial networks. This device performs
channel coding and OFDM modulation of a MPEG2 transport stream. One single
unit drives the Atlas Series™ transmitter with a fully modulated RF DVB-T
channel. The excellent quality and stability of analogue UHF signal output
maximises the TV transmitter efficiency, decreasing global cost. Thanks to its ASI
(Asynchronous Serial Interface) standardised interface, the V-XCAST exciter can
be used with any DVB compliant source equipment.

A flexible Bit Rate Adaptation mechanism, with PCR (Program Clock Reference)
restamping, is provided, giving an independence between the multiplexer rate and
the DVB-T rate.

Test generators are included, which allow easier BER (Bit Error Rate) measurement
with the optional V-TER, professional test receiver.

The V-XCAST COFDM exciter accepts a SFN (Single Frequency Network) option
which allows to set up single frequency networks with use of a SFN adapter at the
DVB multiplexer site. In SFN mode, the COFDM modulation and RF up-converter
are locked on a stable 10 MHz external reference coming from GPS (Global
Positioning System). With the optional internal GPS receiver, the V-XCAST offers
a compact and reliable SFN modulation solution.

The full device remote control can be performed via the MIP channel (remote
control from network head-end), or via an RS232 port and the PC software (local
control or remote control via modem) or via a standard SNMP (Simple Network
Management Protocol) manager, allowing a very fast integration with most Control
Systems.

The same PC software can be used for easy logging and maintenance, thanks to an
accessible rear panel RS-232 connector. It will be used to adjust digital
precorrection curves.

Alarms are monitored on front panel leds and on a rear side connector as relay
contacts. Alarms are optionally controlled and monitored by standard SNMP
managers.

2.3 Installation Checkboxes

Located to the left of each important step in the installation procedure is a checkbox
like the one to the left of this paragraph. As each step in the procedure is completed,
the box should be checked. This provides a quick confidence check at the end of the
procedure that no steps were skipped. The primary goal of each step is also in
bold letters, with the rest of the paragraph being support information toward that
goal.

NOTE:

In case of discrepancy between the connections listed in the schematics ver­sus the information given in this installation section, the wiring information in
the schematics should be considered the most accurate. All connections listed
in this section should be verified with the schematics before initial turn on.

2.4 Transmitter Cabinet Placement

The transmitter cabinet should be placed where it will have approximately 1 meter
clearance on each side and in the back. The front of the transmitter should have a
clearance of at least 1.5 meters to allow access for removal and installation of the
PA and power supply modules. There are several equipment layout drawings
included in the drawing package to help plan the cabinet placement:

should be placed on the right side of Cabinet 1 (looking from the front of the
transmitter). There are holes in the sides of the cabinets which should line up to
allow for interconnect wiring between the cabinets. One hole is approximately in
the middle and the other near the bottom (rear) of the cabinets.

NOTE:

Do not install the PA modules or the power supplies at this time. These will
be installed just before the initial turn on procedure.

2.5 Cooling System Installation

The major components of the Atlas cooling system include the pump module,
cooling control panel and heat exchanger. The following procedure will rely heavily
on the following schematics.

Set the pump module in place and mount the cooling control panel. Use shims

or flat washers to make sure the pump module is level and solid (not rocking). The
cooling control panel should be mounted to a solid surface, or structure, able to
withstand the minor vibration of the contactors without coming loose.

Connect one conduit from the control panel to the pump module and one to the
heat exchanger for AC wiring. Depending on local wiring codes and personal

preference, another set of conduit runs may be installed for the control and status
wires to the pump module and the heat exchanger. The small signal wires and the
AC wiring should never be run in the same conduit.

Open the Isolator switches on the cooling control panel, pump module and heat
exchanger. This will allow them to be closed one at a time later to check for wiring

problems.

Connect the AC wiring between the cooling control panel and the pump
module and heat exchanger. Follow the AC Power Flow Diagrams and Electrical

Installation Diagrams mentioned at the beginning of this section. All AC
connections are connected to terminals labeled X1.

Connect the control and status wires between the cooling control panel and the
pump module with the supplied 16-2-12C (screened) multi-conductor cable.

These connections are on Electrical Installation Drawing, 843-5550-189 or 843­5550-218. These low level signals connect from terminals X1-8 thru X1-15 in the

If there is a temperature overload switch on the test load, (as would be the case
for an air cooled load) it should be connected to J18-11 and J18-12. This will

mute the transmitter rf output if the test load temperature threshold is exceeded. A
closed contact is required to operate the transmitter. A jumper is installed at the
factory which must be removed to use this input.

For the DVL 4300 and DVL 5700only, connect the cabinet combiner reject
load coolant flow switch. The DVL 4300 and DVL 5700 use a liquid cooled reject

load for the cabinet combiner. The flow switch connection, as shown on drawing
#843-5550-218, will mute the transmitter rf output if there is no coolant flow
through the reject load. Specified wire is 7-2-4C, 4 conductor cable. A closed
contact is required to operate the transmitter. Some switches may also use +15V and
ground. The connections are as follows:

• J18-11 to flow switch terminal 1 (common)

The DVL1500 -DVL5700 models are 3 phase 380/400/415Vac at 50/60Hz delta or
wye. The DVL400 - DVL1100 models are equipped for single phase 220/240Vac at
50/60Hz. If voltage variations in excess of +10/-15% are anticipated, the transmitter
power input must be equipped with automatic voltage regulators (optional
equipment) capable of correcting the mains voltage.

NOTE:

It is important that the correct voltage be specified as the MOV protection
components are different for delta, wye or single phase configurations.

Connect the Primary AC conduit to the top of the transmitter cabinet.

The top of the transmitter cabinet has pre-cut holes for conduit connections as
shown in the outline drawing. The AC input is routed down through the hollow
space on the left side of the transmitter cabinet and out through a hole near the base
of the cabinet and up to the front of the cabinet behind the breaker panel.

NOTE:

There must be less than a 5% imbalance between the phases to allow the
transmitter to operate.

Verify that the single phase step-down transformer is tapped correctly. This
step is not required on single phase transmitters. Step-down transformer T1

reduces the 380/400/415Vac down to 220Vac for the transmitter low voltage power
supplies, fans and exciters. Using the voltage measured above, check the primary
tapping of T1. TB4 is used to re-tap the transformer if necessary, by moving wire

2.7 Second PA Cabinet Interconnections

NOTE:

The following only applies to the DVL 4300 and the DVL 5700 transmitters
which have an additional PA Cabinet (Cabinet 2).

The following interconnects will have to be made between from the Main PA/
Control cabinet (called Cabinet 1) to the Additional PA Cabinet (called Cabinet 2).
This information is found on schematics 843-5550-004 and 843-5550-100. The
following cables are labeled and already have one end connected to Cabinet 1 where
they were bundled for shipping. The cables should be routed through the
appropriate hole between the cabinets for connection to Cabinet 2.

Connect the 220VAC from the stepdown transformer in Cabinet 1, to TB2 in
Cabinet 2 for the low voltage supplies. The connections are as follows:

• Wire W61 connects from TB2 terminal #3 in Cabinet 1 to TB2 terminal #1 in

Cabinet 2.

• Wire W62 connects from TB2 terminal #6 in Cabinet 1 to TB2 terminal #4 in

Cabinet 2.

Connect the 3 phase ac wiring from TB1 in Cabinet 1 to TB1 in Cabinet 2. The
connections are as follows:

• Wire #21 connects from TB1-3 in Cabinet 1 to TB1-3 in Cabinet 2.

• Wire #22 connects from TB1-7 in Cabinet 1 to TB1-8 in Cabinet 2.

• Wire #23 connects from TB1-11 in Cabinet 1 to TB1-13 in Cabinet 2.

2.8 Signal and Ground Connections

NOTE:

Control and signal wires should never be run in the same conduit with any
AC wiring. A separate conduit should be used for control and signal cables.

Connect an MPEG Transport Stream DVB ASI input to each exciter.
Depending on purchased options, each exciter also has inputs for a GPS Aerial, 1
PPS input, 10MHz Reference and Demodulator A. For more information refer to
the V-XCAST exciter manual.

Connect the sample cables from the Forward and
Reflected directional couplers at the system output
(after the filter). These samples connect to a small

Customer I/O panel, with 2 "N" style connectors,
mounted to the ceiling of the cabinet. J1 is for Total
Forward and J2 is for Total Reflected. If necessary, these
samples will be calibrated using the GUI after initial
turn-on. These cables are not supplied since the required
length is determined at each site. For 2 cabinet systems
see 2.10.1 RF Sample Connections.

Connect a ground strap from the transmitter cabinet
E7 to the station ground. There is a brass ground block

located in the center of the cabinet. Remove the block,
punch holes in the copper ground strap and then mount
the strap under the block. The copper strap must be at
least 5cm wide and 0.5mm thick.

2.9 External Interlock Connections

The transmitter has inputs for up to four external interlocks on the External I/O
Board. More may be used by placing 2 or more interlocks in series. The transmitter
is shipped from the factory with jumpers in the External Interlock positions which
will allow the transmitter to operate with no external interlock connections. The
electrical installation drawing (843-5550-189 or 843-5550-218) shows that
Interlock #1, J18-1 to J18-2, is used by the 3 Port U-Link Panel or possibly a
motorized switch. The other three are to be used at the customers discretion. The
External Interlock circuit requires a closed connection between all of the following
terminals on the External I/O Board to turn the transmitter on:

• J18 pins 1-2 (connected to 3 Port U-Link Panel or switch)

• J18 pins 3-4

• J18 pins 5-6

• J18 pins 7-8

2.10 Cabinet Combiner Connections
(DVL 4300 and 5700 only)

Drawing #843-5550-172 shows one possible layout of the rf equipment for the high
power systems. This includes the connections and locations of the hybrid combiner,
reject load, filter and patch panel.

Each PA cabinet has a 1 5/8" rf output line which connects to the hybrid combiner.
The hybrid is marked for Cabinet1, Cabinet 2, Output and Reject Load connections.

NOTE:

It is very important that the cabinets be connected to the correct hybrid port.
If they are reversed then all of the power will end up in the reject load port. If
this happens, the drive cables (W57 and 73) at the output of the DCU should
be reversed as well.

Precision directional couplers for measuring forward and reflected power should be
installed both before the filter and at the system output for measuring and
calibrating power. If the precision couplers are supplied by Harris, they will come
with a coupling chart which can be used for calbration purposes.

2.10.1 RF Sample Connections

Connect the RF Sample from the cabinet combiner reject load to J17 of the RF
monitor board in Cabinet 1. The hybrid combiner reject load is a water cooled

load which should also have an rf sample port between it and the hybrid. This
sample coupler is labeled DC4 on the 843-5550-100 Additional Cabinet Wiring
Diagram. This sample is used for Cabinet Phasing. This cable is not included since
the required length is determined at each site.

Connect the System Forward and Reflected directional coupler to the
transmitter. These samples connect to a small Customer I/O panel, with 2 "N" style

connectors, mounted to the ceiling of the cabinet. J1 is for Total Forward and J2 is
for Total Reflected. If necessary, these samples will be calibrated using the GUI
after initial turn-on. These cables are not supplied since the required length is
determined at each site.

NOTE:

For 2 cabinet systems these samples can be taken at DC3 (directional coupler

3) which is after the cabinet combiner but before the filter or can be con­nected to the directional coupler after the filter. The choice of which sample
to use is to be decided by the customer or by site requirements.

2.11 3 Port U-Link Panel Connections

Refer to the Electrical Installation drawing 843-5550-189 or 843-5550-218 for the
following connections:

Connect X1-1 and X1-2 on the U-Link panel to J18-1 and J18-2 (respectively)
on the External I/O Board in the transmitter. This is the transmitter external

interlock input and will shut the transmitter off if the U-Link is removed during
operation. A closed contact between J18-1 and J18-2 is required for the transmitter
to operate. Specified wire is 16-2-2C (screened) 2 conductor cable.

!

CAUTION:

ALWAYS SHUT THE TRANSMITTER OFF BEFORE REMOVING THE U-LINK TO
PREVENT POSSIBLE DAMAGE TO THE CONTACTS.

Connect one jumper between X1-3 and X1-4 and another between X1-5 and
X1-6 on the patch panel. This places the U-Link microswitches in series with the

interlock line to the transmitter. These may already be installed. This will only
allow the transmitter to be turned on if the U-Link is installed.

Connect the U-Link status switches S1B and S2B to the RF switch status inputs
on J14 of the External I/O Board in the transmitter. This allows the GUI to

display the position of the U-link panel and will cause a transmitter mute if neither
of these connections are pulled low. Specified wire is 7-2-4C (screened) 4
conductor cable. These four connections include:

• X1-7 to J14-3

• X1-9 to J14-4

• X1-8 and X1-10 both connect to J14-6 (ground)

*Verify these connections with the Electrical Installation drawing 843-5550-189 or

843-5550-218.

NOTE:

If an RF switch is used in place of the 3 port patch panel then an additional con­nection of the RF_SW_SEL_OUT at J15-9 on the External I/O board will have
to be connected to the select input on the switch. This output is a TTL open col­lector, active low, momentary signal meant to cause a switch to the opposite
position. The rf switch should then latch in that position until pulsed again.

IMPORTANT: This note only applies to systems without a patch panel or rf switch.

If no patch panel or switch is to be installed in the transmitter RF output line, then a
jumper must be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1
(ground).

NOTE:

The PA Modules should be placed into the same slot in which they were
tested at the factory. Each module has a serial number tag. This serial number
is recorded on the factory test data sheet along with the appropriate slot num­ber. Placing the module in a different slot will not cause any harm to the
transmitter but will require more time for module phasing.

Connect the Coolant hoses to the rear of the PA
Modules. Green hoses on the bottom and blue hoses

on the top. Push the hose coupling on to the module
nipple until it locks into place. Make sure the coolant
valves on the couplers are in the open position as

WARNING: Disconnect primary power prior to servicing.

Section 2 Installation / Initial Turn-On ATLAS Series™

For single cabinet systems (up to DVL 3000) slowly bring up the transmitter
power to the nominal value, as indicated by the bar graph. Monitor the cabinet

forward and reflected powers, as well as the VSWR reading. A large VSWR (above

1.1) is indicative of a bad RF connection to the test load.

Check PA Module Phasing. For Single Cabinet systems, check the PA Module
phasing. If any of the PA Module reject load sample levels are above 0030, proceed
to "5.4 PA Module Phasing" on page 5-5.

Verify that the transmitter meter readings are close to the factory test data
meter readings, mainly all of the current and voltage readings.

2.13.4 Cabinet Phasing

NOTE:

This section only applies to DVL 4300 and DVL 5700, 2 cabinet transmitters.

As long as the PA modules have been placed back into their factory tested postions,
neither cabinet should require any PA Module phasing. However, since the output
system will probably have changed on-site, phasing of the 2 cabinets will most
likely be required. At full nominal power output all of the detected rf sample
readings shown in Figure 2-9 should read below 0030 with the Gain button set to
LOW or below 0100 with the gain button set to HIGH. To access the PA Reject
Service screen press OUTPUT, OUTPUT SERVICE and then PA REJECT
SERVICE.

STEP 1 To adjust the cabinet phasing, slowly raise the

transmitter power until you reach the nominal
operating power or the cabinet combiner reject load
sample reading goes above 300, whichever comes
first.

STEP 2 Next, press the Cab1 or Cab2 button (it does not

matter which) and tap the Phase Adjust +/- buttons
to minimize the reading above the buttons.
Alternately adjust the phase of the 2 cabinets to
reduce the reject sample level below 0030.

STEP 3 If full output power was not reached in step 1, raise the transmitter

power to 100%. Repeat Step 2 if the cabinet combiner reject sample
gets above 0030.

STEP 4 If any of the PA Module reject readings are above 0030 proceed to

"5.4 PA Module Phasing" on page 5-5, and then readjust the cabinet
phasing if necessary.

Verify that the transmitter meter readings are close to the factory test data
meter readings, mainly all of the current and voltage readings.

3.1 Introduction

This section gives detailed operational information for the Atlas™ Series Solid­State UHF DVB-T transmitter. Information will pertain mostly to the operation and
navigation of the Graphical User interface (GUI) Touchscreen display.

NOTE:

Operation of the V-XCAST exciter is covered in a separate manual which
came with the transmitter.

3.2 Transmitter Control Panel

The front panel user interface is a 1/4 VGA, LCD touchscreen display. The
touchscreen display uses software buttons to monitor the transmitter. Hardware
buttons for the primary transmitter functions such as ON/OFF, RAISE/LOWER and
Remote Enable/Disable are provided on the overlay panel next to the display as
shown in Figure 3-1.

Section 3 Operation ATLAS Series™

NOTE:

A similar set of GUI screens is available via web browser with an ethernet
network connection and the optional network interface box.

3.2.1 Main Menu "Quick" Buttons

Just to the right of the touchscreen, there are 5
hardware buttons which are part of the front panel
overlay. Located next to each button is a Status
LED which illuminates green under normal, no
fault conditions. These buttons provide quick
access to each of the 5 main transmitter groups,
namely:

a. Drive Chain
b. Power Amp
c. Output
d. Power Supply
e. System

The Status LED next to the button will turn red if
there is a warning or fault condition in that section
of the transmitter. It will be green if the sub-system
is normal. This provides quick access to the
required and relevant diagnostics information,
without having to be familiar with a menu structure.

NOTE:

To differentiate these buttons from the ones which show up on the LCD dis­play, these will be referred to as "Quick" buttons in the manual text.

3.3 Graphical User Interface (GUI)

The GUI ("Gooey") was designed to provide an intuitive interface into the
transmitter control system. Once you know what information is available, finding
the information you want is simply a matter of following the screens to the desired
section of the transmitter. Menu Trees of all available screens is given at the end of
this section, see "3.10 GUI Menu Structures" on page 3-37.

For the most part, all navigation through the GUI screens is done via the
touchscreen and softkeys (software buttons). The exceptions are the 5 hardware
buttons mentioned above. The touchscreen display is also divided into an active
display area, which will change with each screen, and the global areas which are
present on all screens.

The second line of the display has operational and status information including:

a. ON, Standby, OFF or Fault OFF as well as status information.
b. Transmitter Forward power output reading in numerical format (for multiple

cabinet transmitters this would be a system power reading and not for a single
cabinet). It is important to note that this is the power output after the filter.

c. Transmitter Forward power output reading in a Bargraph format (for multiple

cabinet transmitters this would be a system power reading and not for a single
cabinet). The 100% mark is based on the nominal power level or TPO (Trans­mitter Power Output) entered into the configuration screen. The bargraph will
also turn yellow if the power level is more than 20% higher or lower than the
nominal 100% level.

d. Main Menu Symbols which are basically status for the 5 main transmitter sec-

tions. If illuminated red, that section of the transmitter has one or more faults.
These status indicators correspond to the 5 hardware buttons to the right of
the display.

This top bar in Figure 3-2 should be all green under normal (no fault) operating
conditions. A yellow or red symbol or status indication should be investigated by
the station engineer.

The Drive Chain screen is basically an exciter control and monitoring screen. It has
a power reading for each exciter output and allows the operator to select AUTO or
MANUAL switching mode for the drive chain when the optional dual drive system
is installed. Specifically it includes:

a. The operational and on-air status of 1 or 2 exciters (the second exciter is

optional) as well as the status of the ASI input to each exciter.

NOTE:

The standard V-XCAST exciter comes with only 1 ASI input. A second ASI
input with switching capability is optional.

b. The DCU or Drive Control Unit status and power output to the PA modules.

The DCU is an exciter switcher and a directional coupler to monitor exciter
power. For multiple cabinet system, the DCU also contains a splitter to drive
the second cabinet.

c. A Dual Drive Chain Control box (located at the bottom of the screen). This

section will be grayed out for single exciter systems. For dual exciter systems
this box has 3 switches:

3.9.4.1.1 Control Setup

This screen allows the user to set the Date and time which will be used for reporting
and for the fault log.

It also allows for adjustment of the contrast of the GUI LCD display. The display
contrast will adjust dynamically as the number is changed to allow for room
lighting.

The last box here is the Screen Saver setting. It allows the user to select how long it
will take for the screen to blank out due to inactivity.

The only function button is the Touch Cal or Touchscreen Calibration. This should
not require routine adjustment.

3.9.4.1.2 Touch Screen Calibration

If the touch screen soft buttons on the GUI are working and seem to be accurate,
then this procedure is not required. If the soft buttons on the touch screen do not
seem to work or can only be activated by pressing outside the button graphic, then a
simple touch screen calibration will have to be done as follows:

STEP 1 Go to the touch screen calibration setup screen by pressing the Touch

Cal button in Figure 3-39. If you are not able to get to the screen,
open the control panel and press and hold the Remote Enable and
Disable buttons at the same time and momentarily reset the main
controller. Keep the Enable and Disable buttons pressed until the
display is up and running. After the micro resets, the Main
Controller will prompt the operator to calibrate the touch screen.
