GENERAL DESCRIPTION
Platinum Z Series Features and Benefits
The Harris Platinum Z Series transmitters are a
highly functional, cost-effective, FM radio transmitter,
designed using a concept called Z-Axis 3D electronic
design. The Z-axis approach arranges the system RF
components such as dividers, combiners and
amplifiers in three dimensions, to permit the most
efficient possible signal paths between them. This
method allows the transmitter amplifying group to be
broken down economically into the smallest possible
blocks for servicing and replacement. The ZCD
series transmitters utilize the Harris Digit CD, Digital
FM exciter, while the ZFM series transmitters are
equipped with the Harris SuperCiter, an analog FM
exciter.
All Harris Platinum Z Series transmitters include the
following features and benefits:
•
Power output range: 2 kW to 40 kW. Standard
power levels are 2 kW, 3.5 kW, 5 kW, 7.5 kW,
and 10 kW as well as combined power levels of
20 kW, 30 kW and 40 kW.
•
All ZCD transmitters include the field-proven
Harris DIGIT CD Digital FM Exciter. DIGIT CD
accepts AES3 digital audio and generates a fully
modulated RF carrier totally in the digital domain
for the lowest noise and distortion available in
any FM exciter (16 bit digital audio quality).
•
Redundant, auto switching, IPA amplifiers to
eliminate a single point of failure.
•
Redundant RF amplifier modules that allow
maintenance while the transmitter remains on the
air at reduced power (“Hot-Pluggable” modules).
•
Redundant power supplies to keep the
transmitter on the air in the event of supply failure
(optional in Z2 transmitters).
DIGIT CD Digital FM Exciter
The Harris DIGIT CD FM exciter is supplied as
standard equipment with all Platinum Z transmitters.
The DIGIT CD with its digital input module, generates
the complete stereo FM waveform in the digital
domain, using a digital signal processor (DSP) as a
stereo generator and composite limiter. A 32-bit
numerically controlled oscillator (NCO) is used as a
digital modulator. These digital techniques allow
direct connection of standard AES3 digital stereo
audio data to the FM exciter eliminating the distortion
and alignment problems of analog signal paths and
analog FM exciters. The DIGIT CD is also available
with an analog interface module for stations with
analog program paths and is easily interchangeable
with the digital input module.

SuperCiter Analog FM Exciter
The optional Harris SuperCiter is a high quality 55
watt analog FM exciter designed for broadcasters
needing state-of-the-art analog performance at a
value price. The SuperCiter combines time-proven
PLL technology with modern RF amplifier circuits to
provide driving power for an FM transmitter.
Redundant Exciters
Each Z series transmitter includes one exciter.
Space is available for a second optional exciter. If the
transmitter is not ordered with the optional exciter, all
required exciter RF switching hardware, AC power
and control wiring are included in the Z transmitter. If
in the future an alternate exciter is desired, simply
install the second exciter, connect three cables and
configure the transmitter controller for two exciters via
the front panel interface. The controller will monitor
the exciters for proper operation. If a fault occurs the
controller will switch to the alternate exciter
automatically. It is also possible to manually switch
exciters.
Figure 1
850 Watt PA / IPA Amplifier Module
Size: 9”D x 7”W x 4”H
Weight: 10 pounds
RF Power Combining
The RF amplifiers (one half of a PA module) are first
combined in groups of six or eight (depending on
power level) in a compact Z-Plane isolated combiner.
True isolation means that in the event an amplifier
fails the active modules will continue to work into a
nominal 50Ω load, for almost zero stress to the active
amplifiers. The outputs of the Z-Plane combiners are
then combined further in 3dB hybrid combiners to
produce the final output power. The Z2 transmitter
uses one Z-Plane combiner and its output is the final
output stage of the transmitter.
PA / IPA Modules
The PA and IPA modules are identical and
interchangeable in the Z series transmitters. The
modules consist of two independent RF amplifiers.
Each RF amplifier uses two MOSFET devices
mounted on a compact heat sink assembly and is
capable of providing up to 425 watts of RF output
power. Typically, the amplifiers operate between 320
and 340 watts. The PA module amplifiers plug
directly into an isolated combiner without using
channel sensitive RF cables. The PA modules can be
removed without removing plugs and cables and are
“hot-pluggable”. Each PA module (2 RF amplifiers) is
rated to produce 850 watts of output power into a
system VSWR of 1.5:1 from 0°C to 50°C ambient
temperature at sea level.
Power Supplies
Z series transmitters can be configured with single
phase or three phase power supplies. The power
supplies are step-regulated by reliable tap-selecting
techniques (non-switching design). This approach
provides high conversion efficiency, excellent power
factor and very low line harmonics. The power
supplies are mounted on a front rollout drawer for
complete accessibility and ease of maintenance. The
multiple supply concept protects against total loss of
service due to loss of a single supply. The Z2 is
provided with one supply with an optional second
supply. The Z7.5 and Z10 single phase transmitters
use a second cabinet to house the larger power
supplies. The upper two thirds of the second cabinet
is configured as standard 19” EIA rack space.
The IPA module uses one amplifier to provide the
required drive for its associated PA amplifiers. This
leaves one amplifier as a back-up in the event the
primary IPA amplifier should fail. The transmitter has
built in RF sensing, control logic and switching
hardware which will automatically switch from the
primary IPA amplifier to the back-up in the event an
IPA should fail. The IPA amplifiers can also be
selected manually from the front panel. Figure 1
shows an 850 watt PA module.
Figure 2 shows four three phase power supplies that
have been rolled out the front of the transmitter. The
power supplies are installed in the transmitter for
shipment. Refer to the Electrical/Mechanical/Cooling
2
or Technical Data sheets for power consumption and
fuse sizing for the transmitter of interest.
A second LCD display permits viewing detailed
parameters such as, individual voltages, currents and
temperatures of the PA amps and Power Supplies. A
fault Log displays detailed fault information to assist
in easily pinpointing a problem area and stores up to
32 faults. LED’s are used to flag the fault log content
and other basic status information. Reliable
membrane switches provide a means for browsing
through the diagnostic system. Figure 3 below shows
a top view of the controller, which may be removed
with the transmitter operating.
Figure 2
Four Three Phase Power Supplies
Control System
The Z series transmitters use a microprocessor
based controller which monitors up to 100 operating
parameters and functions of the transmitter. The
controller makes intelligent operating decisions based
on operating conditions. Detailed system information
is available using the front panel diagnostic display
and the controller is designed for direct connection to
standard parallel remote control systems. The
Controller provides VSWR overload protection,
automatic power control, automatic VSWR foldback,
RF power soft start, AC restart and other advanced
functions. The controller includes built-in logic control
for automatically switching to the reserve IPA
amplifier, and an optional backup exciter. The Master
controller is at the heart of the control system. In the
event Master Control communication fails, a backup
Life Support Controller keeps the transmitter on the
air with basic control functions. Individual control
boards for the Power Amplifiers and Power Supplies
are used to control these subsystems. Redundancy
is inherent in the PA and Power Supply control
section as multiple PA and Power Supply boards are
used. The control system front panel includes an
output metering LCD display which is used to view
the following parameters:

Low Pass Filter / Directional Coupler
All Z series transmitters use an efficient internal low
pass filter for RF harmonic attenuation. Directional
coupler ports provide highly accurate forward and
reflected power samples to the controller and are
located just after the low pass filter. An RF sample
with 30 dB of nominal directivity is provided just after
the internal low pass filter as well. This directional RF
sample provides more accurate performance
measurements by supplying a nearly reflection free
RF sample source for external test equipment and
AM noise monitors. Figure 4 shows the low pass
filter line section and the directional coupler/RF
sample ports.

INSTALLATION CONSIDERATIONS
The following sections provide useful information to
assist in planning and installing the Z transmitter.
Prior to installation, the exciter and transmitter
technical manuals should be studied carefully to
obtain a thorough understanding of the principles of
operation, circuitry and nomenclature. This will
facilitate proper installation and initial checkout.
Transmitter Cooling Requirements
The Z series transmitters are designed to operate in
an environment with an intake air temperature
between 0°C and +50°C. Dirt is the number one
enemy of solid-state transmitters and a properly
designed cooling system with adequate filtering is
very important. The Z transmitter air system is
designed to supply sufficient air at the required static
pressure to cool the transmitter only. Additional
pressure losses introduced by exhaust systems and
air supply duct work must be offset by means other
than the transmitter blowers. These inlet and exhaust
system ducts generally need to be installed with
helper fans to offset these losses. Refer to the
Outline Drawings included for detailed information on
intake and exhaust air flow specifications. It is
recommended that the station consult with an HVAC
specialist to determine the requirements of intake and
exhaust ducts in order to meet the flow volumes
required by the transmitter. Outside air which
contains salt or pollution must have those items
removed by an adequate filtration system or a closed
system must be used.

RF Output Termination
The RF output connector of all Z series transmitters
is a standard 3-1/8” EIA Flange. The Z2, 3.5, and 5
transmitters include a 3-1/8” to 1-5/8” Reducer. If 31/8” EIA is desired you can simply remove the
adapter supplied with the transmitter. If you require
1-5/8” EIA output on your Z7.5 or Z10 transmitter,
please specify this when ordering.
Figure 6 is an example of an air system that should
be avoided. The system shown here would starve
the transmitter for fresh air and proper cooling would
not be expected in this situation.

Harris recommends the next two examples of air
systems and the closed system will provide the
cleanest air for the transmitter. In harsh
environments a closed air system is recommended;
that is, an air-conditioned room that re-circulates and
properly filters the room air. In a closed air system
there is normally no venting to the outside. The heat
in the room is removed by the air conditioning unit.
This is the ideal system in terms of room cleanliness.
The operating cost of a closed system will depend on
the amount of heat generated by the equipment, as
well as environmental factors. The closed system
may be your best choice if the outside air is salty,
dirty, hot, or humid. However, if you choose to
implement this system, you should include back-up
ventilation to protect the facility in the event of an air
conditioning unit failure.

Closed Air System
Another configuration that keeps the transmitter
adequately clean and properly ventilated is a positive
pressure system. In this system outside filtered air is
brought into the room using an air intake fan.
Transmitter exhaust air is removed from the room
using a duct hood over the transmitter with an assist
fan. The exhaust assist fan should be sized about
5% larger than the transmitter CFM specifications.
The building air intake fan should be sized 10-15%
larger than the exhaust helper fan. The slight
positive pressure in the room will ensure proper
transmitter ventilation and will keep dust and dirt from
entering the room through small leaks in the building.
With a closed system, the amount of air conditioning
needed would be at least equal to the equipment’s
dissipated heat over and above the amount of cooling
needed without the transmission equipment. The
amount of heat that the equipment generates
depends on the amount of power dissipated in heat
into the transmitter room. Therefore, if you expect to
be able to operate the transmitter into an air cooled
test load without raising the room temperature, the air
conditioning will have to be large enough to handle
the full wattage consumed by the transmitter.
The exhaust duct is best left detached from the
transmitter by about six inches, similar to a range
hood. This will allow a path for the exhaust air in the
event the assist fan fails or the exhaust duct
becomes blocked. The positive pressure system is
only adequate in environments where the maximum
outside air temperature does not exceed 50° C.
While the transmitter is specified to operate up to 50°
C it is best to try and keep the transmitter air inlet
temperature to no more than 30° C.
Figure 8 is an example of a positive pressure system.
The conversion from watts dissipated in heat to
BTU/hour is:
BTU/hour = Dissipated Power (kilowatts) X 3415
TONS = BTU/hour ÷ 12,000
At reduced power, any FM transmitter will generate
less heat, but not proportionately less. For example,
a transmitter operating at half of its rated power will
produce more than half of its dissipation at full power.
This is because some circuitry consumes the same
amount of power and other circuits become less
efficient at reduced power levels. The total power
consumption of your transmitter can be calculated by
using the current and voltage values on the factory
test data sheet. You may also contact the Harris Field
Service Department. They can assist in determining
the power consumption and efficiency of the
transmitter especially at powers other than
nameplate. Figure 7 is an example of a closed air
system.

A hybrid air system includes both air conditioning and
ventilation of the transmitter exhaust to the outside.
Typically, the air intake of the transmitter (rear) is
located near the filtered air intake of the building.
The exhaust air of the transmitter (top) is removed as
described in the positive pressure system. The front
portion of the transmitter room is cooled with air
conditioning. A second hybrid method is to build a
wall along the front of the transmitter isolating the
front of the transmitter from the rear. The rear portion
of the building is set up as a positive pressure system
while the front is air conditioned. Figure 9 shows an
example of a hybrid system.
The single phase Z7.5 and Z10 transmitters require
two cabinets, for the larger single phase power
supply components. The left hand cabinet holds the
controller, power amplifiers, and two power supplies.
The right hand cabinet will house the two remaining
power supplies. One advantage of the second
cabinet is that the upper two thirds of the cabinet is
empty and configured as standard 19” EIA rack
space for mounting auxiliary equipment. Refer to the
Outline Drawing included for detailed dimensions.

Harris recommends consulting with your HVAC
specialist to determine the requirements for your
particular site.
All Z series transmitters can be configured with either
a single phase or three phase power supply. The
transmitter is shipped with the power supplies in
place. The power transformers will be tapped at the
factory for the primary AC voltage that is specified at
the time the order is taken. This voltage will be
documented in the factory test data accompanying
the transmitter and tagged at the main contactor input
at the rear of the transmitter. The line voltage at the
site should be measured to ensure it matches the
tagged voltage. If a change is required the input
voltage strapping chart is shown on the Overall
System Block Diagram in the drawing package
included with the transmitter.
Transmitter Placement
Transmitter AC Input Wiring
The transmitter will require a fairly level surface to
rest on. If the transmitter is not on a level surface a
level and shims should be used in order to ensure the
unit is level and stable before continuing the
installation. The transmitter should be placed with
AC power and signal connections in mind. The
sidewalls of the FM transmitter may be placed
against a wall or other equipment, access to the
sides of the transmitter is not required. Complete
access is through the front and rear of the
transmitter. The floor must be capable of supporting a
load of 250 pounds per-square-foot
(1221 kg per-square-meter). The power supplies roll
out the front of the transmitter for system
maintenance. Therefore, the transmitter should not
be set up on 4X4 blocks or similar supports. Be sure
to have a smooth flat surface in front of the
transmitter of at least 36 inches for power supply
maintenance. For Dual transmitter installations be
sure transmitter A is positioned on the left and
transmitter B is positioned on the right, as you view
the system from the front. Refer to the Outline
The Z series transmitters can be configured for the
following AC line configurations:

The AC input wiring should be in agreement with
local electrical codes. The AC mains wiring,
disconnect and fuses should be sized for the
transmitters full rated output power to accommodate
future TPO changes. An AC primary disconnect or
means to completely de-energize the transmitter
primary circuit for servicing is required. Harris
recommends a fused disconnect for the transmitter
primary AC power feed(s). Fuses will provide
improved long term reliability and nuisance free
service over a circuit breaker with an equal rating.
The recommended fuse type is a class RK5, a dual
element time delay fuse. Examples of an RK5 fuse
are the Bussmann FRN-R (250V), FRS-R (600V),
Littelfuse FLNR (250V), FLSR (600V), and Ferraz gG
6
fuses. If you prefer to use a circuit breaker in your
installation, select one with a motor-starting trip curve
similar to that of the RK5 curve for fuses. This type of
delayed response is needed in order to
accommodate the momentary in-rush current when
the transmitter is turned on.
this configuration. The system load is not perfectly
balanced, requiring neutral current to maintain proper
phase to neutral voltages. A poor neutral connection
could cause damage to elements in the transmitter.
The AC power source for the transmitter should be a
low impedance, 50/60Hz, three phase or dual feed
single phase depending on the type of power supply,
with sufficient capacity to operate the transmitter at
its maximum rated output power. The current ratings,
nominal fuse sizes and wire gauges for typical AC
line configurations are listed in the Electrical,
Mechanical and Cooling data sheets included. The
single phase Z7.5 and Z10 require a dual single
phase feed to each transmitter cabinet. The fuse
ratings in the Electrical, Mechanical and Cooling data
sheets are rated for each feed, not both. Each
cabinet is fused separately.
The importance of a good grounding system and
lightning protection can hardly be overemphasized for
reasons of personnel safety, protection of the
equipment, and equipment performance. Lightning
and transient energy via the power line or tower
connections can impose serious threats to your
personal safety as well as damage to the equipment.
A ground system that has been in place for a long
period of time can deteriorate and should be
inspected periodically. This is especially true at the
point where the ground strap enters or exits the
building. All ground connections should be bolted
and brazed together. This low impedance path will
help carry lightning or transient current directly into
the ground instead of into your equipment.
Transmitter Grounding
The AC input wiring terminates at the top of the AC
mains contactor K1. K1 is located at the top right
side in the rear of the cabinet as shown in figure 10.
There are knockouts for AC power and control cables
at the top, bottom and sides of the transmitter. See
the outline drawings included for detailed dimensions
and locations of these knockouts.

&RQWDFWRU
.
The basic elements of a ground system should
include substantial grounding of tower guy wires (at
each anchor point) and each tower leg using 8-10
foot copper ground rods. Ensure the power company
has provided proper grounding of the AC mains
power at the site as well. While there are different
schools of thought on grounding techniques the star
point grounding system is commonly used in
broadcasting. In a star point ground system there is
one common or star point where all grounds join
together at a single point. This point is often a
selected point along a ground system that encircles
the building using copper strap and multiple ground
rods. The number of ground rods will depend on soil
conductivity and the size of the building. The interior
of the building should have a common ground system
made up of 2 or 4 inch copper ground strap, this
ground should be tied to the outside star point and
the AC mains ground should be connected to the star
point. All coaxial cables should enter and exit the
building at a single entry point and their shield(s)
should be connected to a ground plate, which is then
connected to the star point. Harris can provide
copper ground strap, copper screen and bulkhead
entrance ports for your site.
All Z series transmitters come with a 3-foot length of
2-inch copper ground strap, which can be connected
to your site ground system. Figure 11 shows this
strap which is located at the left rear side of the
transmitter as viewed from the back and is connect to
the transmitter chassis.

transmitter site is also recommended. A screw
terminal strip is used to terminate all remote control
connections. The terminal strip converts to a Dconnector which interfaces with the transmitter
controller. The terminal strip is located on the upper
left side wall as viewed from the rear of the. Figure
12 shows the location of the terminal strip.

Surge Protection
Surge protection is an important component of any
transmission system. The Z series transmitters are
designed with built-in MOV surge protection,
providing an added level of protection for the
transmitter. However, the transmitter and other site
equipment are best protected by a transient voltage
surge suppressor (TVSS). The TVSS should be
connected at the sites AC mains entrance and
connected to ground using a copper ground strap in
addition to the standard ground wire provided by your
electrician. There are many levels of TVSS
protection that can be employed depending on the
condition of the source power. Harris recommends a
parallel shunt surge protector as a minimum level of
protection at all sites. A few recommended TVSS
units which provide adequate protection in most
cases are listed in the accessory section of this
manual. More sophisticated series/parallel devices
are available from Harris if needed. You may contact
your Sales Representative for more information
regarding products and pricing.

lengths terminated with BNC connectors and ground
lugs on the outer shield can be ordered from the
Harris Parts Department.
The layout of the terminal block and the commands,
status and metering outputs are shown in figure 13.
Always use shielded cable for the remote control

Maximum external supply voltage should not exceed
+28VDC. It should be noted the maximum status line
current is 25mA. If the output is used to drive a small
printed circuit board type relay, check the current
requirements for the relay coil and be sure to install a
reverse biased protection diode across the coil. A

3-phase: 1; 1-phase: 2.
1- and 3-phase units: RF Cabinet: 28.6” (72.6cm) W x 49.72” ( 126.3cm) D x 72”
(183cm) H. 1-phase units: additional cabinet of height and width equal to the RF
cabinet, depth = 38” ( 96.5cm), with 38” (22 R.U.) of 19” EIA panel mounting space
available for customer-supplied components.
3-phase: 1,750 lbs (795kg); 1-phase: 2,300 lbs. (1,045kg).
Internal.
3-1/8” EIA flange, female.
Barrier strip inside upper left sidewall of main cabinet (facing rear of transmitter).
NOTES:
1. At full output power. Fuse/breaker size should be reduced for significantly lower operating powers, maintaining about a 2X factor above
the normal operating current. Contact Harris salesman or factory for the expected value.
2. Wall-mounted fused disconnect(s) or breaker(s) are customer-supplied item(s). An RK5 class fuse such as the Bussman FRN-R(250V),
FRS-R(600V) or LittleFuse FLNR(250V), FLSR(600V) is recommended. If a circuit breaker is used it should have a trip curve similar to that
of the RK5 fuse trip curve.
3. All transmitter wiring should be done in conformance with local electrical codes.
4. For 1-phase units, breakers and wire sizes are given per feed to each cabinet (two cabinets, total).
5. See Harris drawing 852-9199-011 for complete dimensional information.
