lll -- TRANSMITTER INSTALLATION
lll -- TRANSMITTER INSTALLATION Page 1 of 2
To ensure long and reliable trouble-free service from the UTX5K ULTRA-2 transmitter the following steps
for installation are recommended:
1.
MECHANICAL INSTALLATION: The UTX5K ULTRA-2 was designed to be installed in a building
protected from the weather. The building should have a hard-surface floor such as concrete with a
moisture barrier. This barrier could be pressure-treated wood sub flooring which could be anchored
to the concrete and to the transmitter to make the installation earthquake resistant.
Allow a minimum of three feet around the transmitter cabinet for service access. The top of the
transmitter should be clear for three feet above to allow the air to exhaust from the transmitter.
Air flow thru the transmitter is approximately 2,000 CFM. Provisions for air inlet and exhaust from
the room must allow air flow with minimal obstruction. In the event that the room temperature
exceeds 35º Celsius (95º F), cooling air must be provided so that the room temperature will not
exceed 35 degrees Celsius under worse case conditions.
Notice: This equipment is HEAVY and must be handled by professional movers with proper
equipment. Any damage caused by the installers is not covered under warranty. Check to ensure
that installing crews have proper insurance coverage.
2.
GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for
safety and operational reasons. A typical installation may be done as follows:
Use a heavy gauge wire such as #2 AWG stranded copper or solid copper buss one (1) inch wide
by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must
be good quality and protected from corrosion. The ground wires should run over the floor and be
connected to the ground rods located outside the building. The wire should not go thru the concrete
floor but over and around it.
3.
AC WIRING: Wiring to the house electrical sub-panel will be routed to the AC terminal
block mounted in the back of the rack.
208 VAC 3 Phase Standard Power Connections
Connections to the AC Main should be made as follows:
--- RED, BLACK AND ORANGE are connected to the 208 VAC 3-PHASE.
--- WHITE WIRE is connected to the NEUTRAL.
---GREEN WIRE is connected to the SAFETY GROUND.
220 VAC Single Phase Optional Power Connections
Connections to the AC Main should be made as follows:
--- RED and BLACK are connected to the 220 VAC.
--- WHITE WIRE is connected to NEUTRAL.
---GREEN WIRE is connected to SAFETY GROUND.
NOTICE: All wiring of this type must be done by a QUALIFIED ELECTRICIAN and must
conform to LOCAL and NATIONAL wiring CODES.
Consult with your electrician to ensure that the proper breaker size is selected for the main circuit.

lV -- TRANSMITTER TURN-ON PROCEDURE
lV --- TRANSMITTER TURN-ON PROCEDURE
Before applying AC Power to the transmitter for initial turn-on and check out, the installation should be approved by
a qualified broadcast engineer. The turn-on procedure that follows is recommended by Pineapple Technology, Inc.
engineering staff:
1.
Check transmitter load or antenna for proper installation and connection to the transmitter.
2.
Open the transmitter and inspect all cables and wires for loose connections or broken wires in the rack assembly.
3.
Check for damage to the equipment mounted in the racks.
4.
Check all AC breakers and on/off switched to ensure that they are all in the OFF position.
5.
Turn-on the Main AC breaker(s) located in the house service sub-panel.
6.
Turn-on the Main AC breaker (CB-1) on the ACDIS5 Power Distribution panel. Each panel should display a light
indicating power is on.
7.
Turn-on CB13 on the ACDIS5 panel. The AUX Panel should now have the green AC ON lamp lighted. This supplies
power to the AC duplex outlets on the AUX panel.
8.
Turn-on CB12 on each ACDIS5 panel. This supplies 110 VAC power to the transmitter
9.
Turn-on the AC Power switch located on the front panel of the ADP500. The indicating lights should be on and
ready for operation.
10.
Turn-on the AUX breaker CB-2 located on the ACDIS5 Power Distribution panel. The PA Fans and the rack exhaust
Fan should come on.
11.
Turn-on the power supply breakers, CB-3 thru CB-8, located on the ACDIS5 Power panel. Check the PS12KW Power
Supply to see if the green lights are on indicating normal operation. (Note: There are six green lights is the PS12KW)
12.
Using the ADP500 and PAS6 panel, check the idling currents on each PA to ensure that the currents are in the
correct range. Typical range is 0.5 to 2.5 Amps. See ADP500 Operating Section for details. Turn the rotary switch to
the P FWRD position.
NOTICE: The Modulator has been set at the factory so that the output power indication on the ADP500 will show 100%
or 2 KW p-sync power level. It is important to read the instruction manual supplied with the modulator to locate key
adjustment devices on the front panel. The output level adjustment will be necessary for the next step
in the turn-on procedure.
13.
Turn-on the power switch located on the UDR100AC front panel.
14.
Apply a video signal (1 volt P-P) to the video input terminal.
15.
Verify the display rocker switch on the MA2000 Modulator is in the VIDEO or down position and three (3) green
bars appear on the display bar graph.
16.
Slowly increase the output level adjustment while watching the RF Output level on the APD500 meter until it
reads to 50%.
17.
Using the ADP500 reflected power indication, check the LOAD reflected power. This should be less than 5%
reflected.
18.
Return to the PA current readings on the ADP500 to verify that all the currents are approximately the same.
19.
With successful performance to Step 17, the transmitter output power can be increased using the output level
adjustment on the modulator to achieve 100%. The aural power can be added at this time not exceeding 10%
of output p-sync power as indicated on the ADP500.

V --- THEORY OF OPERATION (Page 1 of 5)
A. INTRODUCTION
The UTX5K ULTRA-2 transmitter was designed to meet or exceed all FCC applicable specifications for
TV broadcast equipment. Special attention was given to the selection of sub-assemblies and components
to achieve maximum reliability and minimum down time. The construction of the UTX5K ULTRA-2 is
BASIC and MODULAR with most components field replaceable. Special emphasis was placed on
"KEEPING IT SIMPLE" and returning to more traditional transmitter layouts and instrumentation.
This transmitter was designed for Analog (NTSC) transmission with provisions and options available to
convert to Digital Service at a later date if necessary.
Refer to the UTX5K ULTRA-2 block diagram for an overview of the transmitter architecture. This will give
the technician basic information needed to understand the operation of the transmitter and the function
of each subassembly.
SEE SECTION Vl.A FOR PARTS LIST AND BLOCK DIAGRAM.
B. ADCIS5 AC DISTRIBUTION
The ACDIS5 is the primary AC power inlet for the transmitter. The UTX5K ULTRA-2 transmitter was designed
for Standard 208 to 230 VAC 3-Phase using a FIVE (5) wire connection. The transmitter can be Optionally
powered as 220 to 240 VAC Single Phase using a four (4) wire connection.
Optional
--- 2 wires for 220 -240 VAC Single Phase
--- 1 wire for neutral connection
--- 1 wire for safety ground connection
Standard
--- 3 wires for 208 - 240 VAC 3 Phase
--- 1 wire for neutral connection
--- 1 wire for safety ground connection
CAUTION: Connection to the AC Primary source must be made using all five wires listed above. Follow
the wiring instruction given in TRANSMITTER INSTALLATION Section lll.3. If not followed, severe damage to
the transmitter and, or, electrical shock could result.
The ACDIS5 performs the following functions:
1. Provides a primary AC power breaker point to shutdown the transmitter.
2. Provides 208 VAC power to each of the 2.2KW DC power supplies with individual breaker points for
added safety.
3. Provides 110 VAC circuits for Modulator, ADP500, ABS (as necessary) and AUX Power where
needed.
SEE SECTION Vl.B FOR SCHEMATIC AND PARTS LIST
C. PS12KW POWER SUPPLY
The UTX5K ULTRA-2 transmitter is designed with over 12 KW of DC power. To achieve this level, the modules
mounted in the power supply in the transmitter rack consist of six (6) AC2008 power units with two (2)
AC2009 main frame assemblies each of which are capable of managing three (3) 2 KW modules each.
The power modules are "HOT PLUGGABLE" and can be removed or installed without turning off the
transmitter.
Each power supply module has OVER VOLTAGE, OVER CURRENT AND OVER TEMPERATURE
protection as well as a fault signal in the event of a failure.

D. ADP500 AND PAS6 PERFORMANCE MONITOR
The ADP500 and PAS6 Performance Monitor provides the following functions:
1.
Monitors FORWARD AND REFLECTED POWER to the hybrid combiner and presents it as a percentage
of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the transmitter.
2.
Provides a HIGH ANTENNA VSWR MONITOR in the event of an antenna or coax failure where
the reflected power exceeds 25% the transmitter will shut down. The front panel LED will change
from green to red in case of a fault.
3.
Provides current monitoring of all the pallets used in the six (6) PA1K power amplifier assemblies. The
current levels can be read directly from the multi-meter on the front panel. Individual pallets are
selectable on the ADP500 and the PA assemblies are selected using the PAS6. In normal operation,
a PA FAULT is indicated by going from green to red. RED indicates that the current level is below
500 ma and a transistor could have failed. To read the actual current, select the appropriate PA Bank
using the PAS6. The ADP500 will now display status of each pallet in that PA. The multi-meter will read
the actual current.
4.
A PA INHIBIT switch is provided for failure diagonostic purposes. When activated, this switch allows
the technician to monitor the bias currents for each pallet. These readings were recorded at the factory
and are found on the Transmitter Test Report, DC Test Report Section. This is the best way to
troubleshoot possible transistor problems. When in the PA INHIBIT mode, the RF PWR OFF LED will
change from green to red indicating that the "SHUTDOWN LINE" is at TTL 0 state and the output power
has been reduced to near zero.
5.
An RF MONITOR port (BNC) is available to connect a spectrum analyzer for monitoring the
output signal.
6.
METER SELECTION SWITCHES
The PAS6 is used to select the appropriate PA Module (PA1K) for performance display on the ADP500.
PA designations are PA1 starting from the top row going left to right with PA6 located on the bottom (3rd)
row down on the right side when viewed from the front of the transmitter rack.
The rotary switch on the ADP500 is the detail selector for the multi-meter. The various positons are
defined as follows:

M. AUX MONITOR PANEL
The auxiliary monitor panel provides analog meter measurements for the primary DC supply. The
total power supply current and voltage are displayed on these meters. These measurements serve
as a good indication of the operation of the transmitter final power amplifiers.
Each power supply has a current monitor output. These outputs are accessible on the AUX5 front
panel. Each (PS I Share) test point will indicate a relative amount of current being supplied from the
power supply. This is not a calibrated or accurate measurement that is scaled from the current
capability of the power supply. This is also a second-level diagnostic tool for use by qualified
technicians.
In the event of an EMERGENCY, a SHUTDOWN SWITCH located on the AUX5 will shut down the
transmitter and remove all power starting from the MAIN 3-P BREAKER. To turn the transmitter
on, it is necessary to RECYCLE the SHUTDOWN SWITCH before the transmitter MAIN BREAKER
can be turned on.
N. FP6 FUSE AND SHUNT PANEL
The FP6 serves as a DC SUMMING POINT for all current coming from the power supplies. After being
summed, the current passes through a 1000 AMP precision shunt which is used for measuring the total
supply current and voltage being applied to the transmitter power amplifiers. At this point, the DC power
is distributed to each PA1K amplifier assembly through a series 125 amp fuse.
NOTICE: BEFORE ANY SERVICE WORK IS PERFORMED ON THE FP6 ALL POWER TO THE
TRANSMITTER MUST BE TURNED OFF FOR SAFETY.

VII --- ROUTINE MAINTENANCE (Page 1 of 2)
The following KEY MAINTENANCE AND PERFORMANCE CHECKS should be made monthly or more
frequently in some environments where dust and rodents are problems. Pineapple Technology, Inc.
recommends that the station provide a data log book to maintain these records.
DANGER: SOME OF THE RECOMMENDED TESTS REQUIRE THAT THE TRANSMITTER BE
OPERATING IN NORMAL MODE. THIS PROCEDURE MUST BE PERFORMED BY A
BROADCAST ENGINEER. MORE THAN ONE PERSON SHOULD BE PRESENT IN CASE OF AN
ACCIDENT REQUIRING ASSISTANCE. COMMUNICATIONS TO EMERGENCY SERVICES SHOULD
BE AVAILABLE.
TRANSMITTER
●
This is an integrated 5KW transmitter and is built around six (6) PA1K amplifier assemblies
located in three (3) MFA2PA mainframes.
●
Record the transmitter forward and reflected power on the watt meter provided with the transmitter.
This measured value will vary with picture content.
●
Using the ADP500 and PAS6 record currents for each power LDMOS device in the transmitter.
The absolute measured value will vary with picture content so this is best performed with a fixed
signal such as SMPTE BARS, however, relative measurements are adequate to indicate a
problem at the power device stage. (See operating instructions for ADP500 and PAS6 for more
details).
●
(OPTIONAL) When the transmitter is first put into service it is a good idea to go through each PA
stage and record the static bias level (NO RF DRIVE). This is done by selecting the desired
PA and using the PA INHIBIT switch. When this switch is activated, the PA drive is turned off
and the bias current can be measured. This is a momentary switch because when it is
activated, the PA drive is removed from all the PA's in one half of the transmitter and the output
power will be reduced by 6 db. THIS IS THE BEST METHOD TO USE WHEN
TROUBLESHOOTING A POSSIBLE BAD POWER TRANSISTOR.
●
Record the voltage and current measurements displayed on the AUX meter.
●
Carefully inspect RF Output coaxial cables for excessive heating or discoloration.
●
Check DC Power connections on shunt panels and power supplies for over heating which
could indicate the hardware needs attention.
●
Check DC Connections on the PA rear panel.
●
Remove and clean the air filters located on the front panel of each MFA2PA mainframe assembly.
It is safe to remove the filter while the transmitter is operating. The filters may be cleaned with
a light detergent and dried completely before re-installing. Spare filters are available from
Pineapple Technology, Inc. Request Part Number P/N 990199 when ordering.

FACILITIES
●
Clean all air inlet filters and exhaust outlets to ensure that the transmitter is getting clean
unobstructed airflow.
●
Perform recommended service on air condition systems.
●
Rodent traps or baits should be renewed to keep the facilities clear of these pests which can
cause damage to the transmitter.

VIII -- ADJUSTMENTS AND TUNING
VIII --- ADJUSTMENTS AND TUNING (Page 1 of 2)
The UTX5K ULTRA-2 is a new series of transmitters offered by Pineapple Technology, Inc. The
latest in LDMOS device and circuit technology are employed to ensure reliable and serviceable
operation for many years.
There are very few adjustments necessary to maintain full service condition. The following will
give the technician a general overview of locations for locating these adjustments:
1.
MODULATOR - See details for all adjustments in the Manufacturer's Instruction Manual
provided with your transmitter. Should you have any questions, contact the Pineapple
Technology, Inc Engineering staff for assistance.
2.
BPU10KW - The bandpass filter provided with your transmitter has been tuned at the factory
and adjustments should not be necessary and are not recommended. Any attempt to tune
or modify this filter will void manufacturer's warranty.
3.
U500LD - This is the main PA board in the transmitter. Under normal operation, no adjustments
are necessary. In the unlikely event that a power transistor has to be replaced, the bias
adjustments should be reset to insure optimum operation of the transmitter. The following
procedure should be followed when making bias adjustments:
a.
Remove the PA1K amplifier assembly from the transmitter and set it up on a
sturdy work bench. The bench should be equipped with a 32 VDC power supply with
current capacity of 10 Amps. A VOM will be required to measure the voltage drop
across the precision resistors located on the monitor board.
b.
Attach 50 ohm load resistors to the input port and one to the output port.
If this is not done, severe damage to the PA is possible resulting in costly repair.
c.
Connect the 32 VDC supply to the DC ± terminals. DO NOT TURN THE POWER SUPPLY
ON AT THIS TIME.
d.
Locate the circuits where bias adjustments are necessary. Adjust only those circuits
where service was performed. Turn the bias adjustment POT's fully counter clockwise
You will find two (2) POT's for each power device with one on each gate. These are
small SMT components and require gentle handling.
e.
Locate the current sense resistors on the monitor board. This is a 2 watt .01 ohm
precision resistor. There is one for each device.
f.
Turn the power supply on and measure the +DC to ensure that it reads +32 VDC.
g.
Measure the voltage drop across the precision resistor. This should read zero (0) VDC.
Increase one of the bias POT's slowly till the meter reads 0.009 volts. Increase the
second POT until the reading is 0.018 volts. This completes the adjustment.
h.
Repeat the adjustment above as necessary to set all circuit that have been serviced.
NOTICE: DO NOT USE THE BIAS CURRENT INDICATED ON THE MONITOR PANEL
OF THE ADP500 TO MAKE BIAS ADJUSTMENTS.

VIII --- ADJUSTMENTS AND TUNING (Page 2 of 2)
4.
PA PALLETS - These circuits are "FIXED TURNED" and do not require any field adjustment.
Any questions regarding pallet adjustments should be referred to the factory.
5.
PHASE MATCHED CABLES - If it becomes necessary to replace one of the phase matched
cables, contact Pineapple Technology, Inc. for replacements. These cables are the ones
connected to the input and output ports on the PA1K.
6.
OUTPUT POWER - The transmitter output power measurement is made using a calibrated
wattmeter provided with the transmitter. No adjustments are necessary here.
7.
GAIN & PHASE MATCHING - Under normal conditions it is not necessary to make any gain
or phase adjustments in the transmitter. This transmitter is equipped with provision to adjust
phase and gain to ensure minimum power loss in the dump load and maximum forward
transfer power to the antenna. Contact Pineapple Technology, Inc. for details if this becomes
necessary.

IX -- PROBLEM SOLVING/TROUBLE SHOOTING
IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 1of 3)
The UTX5K ULTRA-2 is a "MODULAR ASSEMBLY" where most of the sub-assemblies can be
removed and or replaced as necessary as necessar to maintain full service. To service this transmitter,
it is best to become familiar with the various sub-assemblies by reviewing the transmitter block diagram
and it's associated subs shown in the introduction. Any work performed on a transmitter licensed by
the FCC must be performed by qualified personnel.
FAILURE ANALYSIS STARTS WITH THE FOLLOWING ASSUMPTIONS:
1. The transmitter is connected to an AC source which is within the specified voltage range
and has ample power to run the transmitter.
2. The antenna has been checked out and a proper match has been verified.
3. The room temperature is < +35 degrees Celsius (+95 degrees Fahrenheit)
4. There are no restrictions in the air flow in or out of the building.
5. The video and aural signals to the modulator comply with stated specifications.
CHECKING THE WARNING LIGHTS
There are several warning signals visible on the front of the transmitter that will alert the technician
of possible problems. When viewed from the front, all the lights should be GREEN indicating normal
operation. An alert signal is indicated by a RED light. We will focus on RED alert signals in this section.
MFA2PA ASSEMBLY
FAN FAULT
RED indicates that the fuse supplying AC to the fan has failed. The fuse
is located just inside the front panel near the top.
CHECK: FUSE AND/OR FAN
DC SUPPLY
RED indicates a loss of +32 VDC to PA
CHECK: DC supply voltage to the rear of the PA1K
CHECK: DC supply fuse located on the Fuse panel located at the bottom
of the rack in the rear.
CHECK: AUX panel location in the bottom half of the rack being checked
for proper voltage and current readings
NOTE: If all the ALERT lights are on in a given reak, this could indicate
that a breaker has tripped
CHECK: Circuit breakers located on the front of the ACDIS5 or the
sub-panel breaker located at the MAIN AC supply.

IX -- PROBLEM SOLVING/TROUBLE SHOOTING
IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 2of 3)
SHUTDOWN
RED indicates that the PA has been "SHUTDOWN". There are two
possible reasons for this:
1. Heat Sink over temperature thermostat has tripped protecting the PA
CHECK: Air inlet filter for possible restrictions to air flow
CHECK: Fan air flow for possible fan fault
CHECK: Room temperature
Note: Heat sink over temperature fault is indicated by the RED alert light going
ON/OFF in cycles varying in duration depending on air flow. The PA
returns to normal operation automatically when the problem is corrected.
2. Remote Shutdown by external signals coming from other protection circuits.
CHECK: Transmitter global protection circuits.
ADP500 MONITOR
The ADP500 is a general purpose test instrument used to display PA status and measure voltage,
current and RF power levels. When combined with the PAS6 it is possible to measure the current
being drawn by each PA RF Device. In addition to its measurement features, it serves to integrate
fault signals for PA Assemblies, High VSWR alarms and provides an interface to the RM8 Remote
Control Unit. The ADP500 is a diagnostic tool for troubleshooting the transmitter.
With normal operating conditions, all the LED's on the front panel are GREEN. Red LED's could
indicate a fault in the transmitter that require attention.
RF PWR OFF LED is RED
Will occur anytime the "SHUTDOWN LINE" (SD) is set to zero (0)
volts. The following conditions will pull the set SD to zero volts:
1. Antenna VSWR HIGH
2. PA INHIBIT SWITCH actuated.
ANT VSWR HIGH LED is RED
This indicates that the antenna reflected power exceeded the set
trip point. This is an internal setting performed at the factory and is
normally set to 10% of the RF OUTPUT POWER set point.
CHECK: The transmitter output connections and antenna for
possible faults. The fault condition will automatically reset when
the problem is corrected.

IX -- PROBLEM SOLVING/TROUBLE SHOOTING
IX - PROBLEM SOLVING & TROUBLE SHOOTING (Page 3 of 3)
PA1 - PA5 LED's are RED
This will indicate that the PA Pallet currents are below the 500 ma
set point. This can occur when the PA Power device has failed.
CHECK 1: Select the PA device in question for current display
on the multi-meter. Compare the reading to the station log. If
abnormal, it is possible that a power transistor has failed.
NOTICE: PA5 will go RED when the INHIBIT SWITCH is
actuated.
CHECK2: To confirm a failed device, it is necessary to shutdown
the transmitter and remove the PA1K power amplifier assembly
and check the device in question. Use a VOM to check the
resistance from the gate of each 1/2 of the device to ground. If
either reading is below 1K ohm it is likely that the device has
failed.
POWER SUPPLY MODULE LED RED
The Power Supply Module has two warning LED's located on the front panel. Normally these LED's are
GREEN indicating that the AC Line voltage and the OVER VOLTAGE circuits are operating properly.
If either LED turns RED the module is question will be turned off and is no longer supplying power
to the transmitter. These modules are "HOT PLUGGABLE" and can be removed from active service
by simply removing it from the main frame. Pineapple Technology, Inc. does not recommend any
attempt to service these modules. Any attempt to service may void factory warranties. Return the
module to Pineapple Technology, Inc. or to the manufacture for service.
NOTICE: If it becomes necessary to operate the transmitter with a missing supply module, very
little if any performance degrading will be experienced. Check the AUX volt meter for any indication
of a drop in voltage (normally 32 VDC). This drop is caused by the power supply modules going into
"CURRENT LIMIT". It is important that the voltage be around 32 volts ±0.5. If the voltage falls below
this point, it can be recovered by reducing the RF Drive level a small amount in most cases.
