Southern Avionics Company’s SE series Transmitters with PC1000C/3, PC1000M/3,
PC1000H/3 or PC3000 Antenna Tuning Units (ATU) and Remote Control Unit (RCU)
have been designed and tested to operate as a standalone Non Directional radio Beacon
system for airplane navigation as part of the Air Traffic Management network. The SE
series Transmitter may also be used as an Inner or Outer Marker Beacon utilized during
an aircraft’s approach to land. This system has been designed to operate on land,
offshore platforms or maritime vessels. The system develops an output power of 10-125
Watts (SE125) or 50-250 Watts (SE250) with a frequency range of 190kHz to 1250kHz.
The system is intended to operate up to an Amplitude Modulation level of 100% while
communicating an alpha numeric Morse Code identifier via on/off keying. The
transmitter’s input voltage requirements are 100-264VAC at 47-63Hz or 48VDC. The

Self Declaration to Essential Requirements

Seamless Operation:

1. The SE Series Dual transmitter system features a completely redundant RF power,
Monitor and Control structure. With dual Transmitter Control microprocessors and
dual RF power sections there is always a secondary system in standby mode to
assume operation should a failure occur in the primary system. A third
microprocessor, the Master Control, serves as the system’s user interface via a
key pad, LCD and embedded Ethernet server. The Master Control also monitors
the status of the primary transmitter and forces a shutdown and subsequent
transfer under faulty conditions, which enables the secondary system to continue
seamless operation.

2. The SE Series transmitter also features a DC power backup to provide seamless
operation should the primary AC voltage source experience a brown out or lose
power. A DC Auto Disconnect protects the external batteries should they reach a
critically low value.

Safety:

1. The SE Series transmitter has been designed, manufactured and tested in order to
offer a safe workin
This is primarily achieved through system design and manufacturing to the health
and safety requirements contained in “Safety of information technology” IEC
60950:1999. Safety designs include proper grounding to reduce shock hazards,

danger labels in appropriate areas and descriptions of hazards and warnings in the
User’s Manual.

2. Specifically the SE Series Transmitter was tested by Retlif Testing Laboratories
per the requirements of the Low Voltage Directive 73/23/EEC. Under 73/23/EEC
the SE Series Transmitter was reviewed to the safety requirements of EN 60950-1,
EN 60950-22 and EN 60945.

Self Declaration to Essential Requirements (continued)

Environmental Constraints:

1. The SE Series Transmitter meets or exceeds the requirements of 2002/95/EC on
the restriction of the use of certain hazardous substances in electrical and
electronic equipment. Design and construction to the requirements of this directive
minimizes or eliminates the concentration of lead, mercury, cadmium, hexavalent
chromium, polybrominated biphenyls or polybrominated diphenyl ethers used in
the SE Series Transmitter system.

2. The SE Series Transmitter utilizes an outside enclosure rated to Ingress Protection
(IP) 66, which was tested to the international standard IEC 60529 Edition 2.1,
2001-02.

3. The SE Series Transmitter is intended to be used in ambient temperature
conditions between -30 and +70 degrees Celsius.

4. The SE Series Transmitter is intended to be used in a non condensing relative
humidity environment with humidity ranging from 0 to 95%.

5. The IP66 rated SE Series Transmitter is suitable for use in high salinity
environments as encountered in offshore conditions.

6. The SE Series transmitter should not be used above 10,000 feet (3048 meters).

Principles governing the logical architecture of systems:

Description of Procedure followed in order to declare suitability of use

1. The SE Series Transmitter system is designed on a fully redundant platform based
on an architecture used by Southern Avionics Company, which has been sold in
the EU for many years. As an option the SE Series design employs an embedded
server using an Ethernet protocol for ease of local and remote interface via
Ethernet or the Internet.

Principles governing the construction of systems:

1. The SE Series Transmitter is designed to maximize modularity of critical printed
circuit boards in both the Master Control and RF Transmitter sections. This
concept allows the fastest upgrade of failed boards without the need for special
tools. The design also affords high availability due to its solid-state design and full
system redundancy.

4 Master Control Panel Description

SDF33011 Rev 1

Figure 4-1. SE Master Control Panel

SE Series Installation and Setup 4-1Master Control Panel Description

SOUTHERN AVIONICS COMPANY

The Master Controller Panel is the main control panel for the SE series transmitters. The
following gives directions on how to operate the SE transmitter using the Master Controller Panel
keypad. The Master Controller keypad consists of 30 keys, 23 LEDs, a 4 line by 40 character
LCD display and dual analog meters.

Definitions:

Meters

The upper analog meter monitors the following three functions:

• Forward Transmit Power - This gives an indication of how much radio frequency transmit

power the SE transmitter is sending to the ATU.

• Reflected Transmit Power - This gives an indication of how much, of the forward power, is

being reflected back to the transmitter from the ATU because of mismatches in the antenna
impedance.

• Modulation - This gives an indication of the modulation index.

The lower analog meter monitors the following two functions:

• Power Amplifier Voltage (PAV) - This gives an indication of the voltage applied to the final

FETS in the Switching Power Amplifier.

• Power Amplifier Current (PAI) - This gives an indication of the current flowing through the

final FETS in the Switching Power Amplifier.

Taking these two values and multiplying them together will give an indication of the power input to
the final FETS.

SPA Power Input = PAV * PAI

The efficiency of the Switching Power Amplifier is calculated by taking the forward transmit power
from the upper meter and dividing this number by the calculated SPA power input to the final
FETS.

Efficiency (%) = (Forward Transmit Power)/(SPA Power Input) * 100%

Keys/LEDs

Frequency Key (FREQ) - This key sets the transmitting frequency of the transmitter. The

transmitter can be set to the desired frequency by pressing the FREQ key, then entering the
desired frequency using the numeric keys and then pressing the ENTER key. Although the
transmitter can cover any frequency from 190.0 KHz to 1800.0 KHz, the Filter/Monitor module
must be configured for the desired frequency.

Tone Key (TONE) - This key sets the tone frequency of the Identifier. The frequency can be
toggled to either 400 Hz or 1020 Hz using the tone key.

Call Sign Key (Call Sign) - This key allows the user to enter the identifier of the station. An
alphanumeric identifier up to 8 characters may be used. The default call sign is "SAC". Using
the numeric part of the keypad, the user may enter the identifier. This type of entry is identical to
text messaging on a cell phone. To begin this procedure, the operator presses the call sign key.
The present call sign, if present, will clear to all blanks. The most significant character is entered

SE Series Installation and Setup4-2 Master Control Panel Description

SOUTHERN AVIONICS COMPANY

first. For example, by pressing the "1" key the first time produces an “A” for the character.
Pressing the key again, changes the character from an “A” to a “B”. If the user continues to press
the "1" key, they would see the character "C" next, then the number "1", and then the character
"A" again. To keep the desired character, wait for 2 seconds and the character place will shift
over. This process continues until the entire identifier is in place. The user presses the enter key
and the identifier is stored into memory. An example of this procedure is as follows for an
Identifier “SAC”. The user would perform the following:

• press "CALL SIGN" key

• press the "7" key once

• wait 2 seconds

• press the "1" key once

• wait 2 seconds

• press the "1" key 3 times

• wait 2 seconds

• press "Enter" key.

This completes the operation.

Mode Key (MODE) - This key toggles between 3 modes of operation the SE transmitter will
operate in. They are:

Ident - In this mode the transmitter will send out the identifier of the transmitter. This process
repeats continuously.

the auto reset circuit will wait for 1 minute before attempting another reset. If the second reset
attempt is unsuccessful, the auto reset circuit will wait for 3 minutes before attempting a third and
final reset. If the third reset attempt is unsuccessful, the auto reset circuit will not attempt another
reset. The switch will toggle auto reset between ON and OFF. An LED (Auto Reset ON)
indicates the status of Auto Reset.

Special Function (SPCL FCTN) - This switch is discussed under the special function section
found elsewhere in this manual.

LCD DATA - This switch allows the user to select the type of data that is seen on the LCD
Display whether it is operating parameters or special parameters including observed frequency,

modulation index, forward and reflected power. The LED's (TX1 TX2) below this switch indicate
which transmitter the data relates to.

UP/DWN Switches above LCD Data - These switches allow the user to scroll up and down
through the data observed or data selections.

Main TX Select (Main TX) - This switch allows the user to select which transmitter is selected as
the main transmitter - TX1 or TX2. The LED's (TX1 TX2) above the switch indicate which TX is
selected.

Monitor Enable (Enable) - This switch enables the transmitting monitoring circuitry. This
function monitors for a number of faults. These are: VSWR, Power, Continuous and No Tone.

RF Meter Select - This switch toggles through forward power, reflected power and modulation
index indicating which parameter is currently being viewed on the RF meter. An LED indicates
the selected parameter.

PA Met er - This switch toggles between PA voltage and PA current indicating which parameter is
displayed on the PA meter. An LED indicates the selected parameter.

Alarm Conditions:

VSWR Overload - This alarm occurs when the VSWR exceeds a preset limit.

Power Output OVER/UNDER - This alarm occurs when the output power either goes below or

above the preset limits set in the transmitter.

No Tone - This alarm occurs if the monitoring circuitry detects a No Tone Condition where the
transmitter is producing a dead carrier.

Continuous Tone - This alarm occurs when the monitoring circuitry detects a continuous tone
and not an identification sequence or low modulation (<70%).

These alarms are indicated by LED’s for each transmitter in the upper middle of the keypad.
These are indicated by:

V = VSWR, P = Power, N = No Tone and C = Continuous Tone

These alarms will cause a transmitter transfer in the case of a dual transmitter and a transmitter
shutdown in the case of a single.

Two other alarms that are indicated on the LCD but not by LED are:

SE Series Installation and Setup4-4 Master Control Panel Description

SOUTHERN AVIONICS COMPANY

Observed Frequency - This alarm occurs when the built in frequency counter detects the
measured frequency is out of tolerance with the desired frequency.

Incorrect Identification - This alarm occurs when the monitoring circuitry detects a different
Identifier from the desired Identifier. The LED's above the monitor enable switch indicate the
present status of the transmitters. The PRI LED indicates the primary transmitter selected by the
main TX select key is the operating transmitter. The SEC LED indicates failure in the Primary
transmitter and the monitoring circuitry has commanded the transmitter to switch to the
secondary transmitter. The fail LED indicates that both transmitters have failed and the system
has shut down.

When testing the SE transmitter, Monitor Enable must be turned OFF.

4.1 Special Functions on the (SPCL FCTN) Key

All Functions are SPCL FCTN Key + Number

SPCL FCTN +1

This mode stores all data into the onboard EEPROM. Once data is stored, the transmitter will
come back to the original settings if AC and DC power are lost.

SPCL FCTN + 2 (Software not available at this time)

This sets the code speed. Display will show default code speed of 8 wpm. Use the UP/DWN
keys to the right of the LCD to slow down or speed up the code speed, with a limit of 5 wpm to 15
wpm.

SPCL FCTN +3 (Software not available at this time)

Master Reset of the Transmitter Controller. This function allows the Master Controller to reset
the transmitters.

SPCL FCTN +4 (Software not available at this time)

Clears Master Reset. This function clears the Master Reset function of the Transmitter Controls
created by SPCL FCTN+3.

SPCL FCTN +5 (Software not available at this time)

This is a special test mode. In this mode the Master Controller will test for under modulation
shutdown. The Master Controller commands the Transmitter Control to decrease the modulation
level by 5 percent intervals in 5 second intervals. As the transmitter changes modulation level, it
is still sending back data on all of the parameters associated with that transmitter. Once the
modulation level drops below an acceptable level, the Master Controller will institute a transmitter
changeover and shutdown of the offending transmitter.

SPCL FCTN +6

This is a special test mode. In this mode the Master Controller will test for improper identification.
The Master Controller commands the Transmitter Control to reverse the identification. After the
transmitter changes identification, it is still sending back data on all of the parameters associated
with that transmitter including identification. Once the identification changes, the Master
Controller will institute a transmitter changeover and shutdown of the offending transmitter.

SE Series Installation and Setup 4-5Master Control Panel Description

SOUTHERN AVIONICS COMPANY

SPCL FCTN +7

This is a special test mode. In this mode, the Master Controller will test for under power
shutdown. The Master Controller commands the Transmitter Controller to decrease the output
power by 5 Watt intervals in 5 seconds intervals. As the transmitter changes power level, it is still
sending back data on all of the parameters associated with that transmitter. Once the power
level drops below an acceptable level, the Master Controller will institute a transmitter
changeover and shutdown of the offending transmitter.

SPCL FCTN +8

This function calibrates the modulation power and frequency for each transmitter. This offset
compensates for the error that exists between the Transmitter Control digital to analog converter
and the measured output.

SPCL FCTN +9

This function configures the DCAD or network for SE systems.

SPCL FCTN +0 (Software not available at this time)

This function puts the Master Controller into a logging mode. It stores all pertinent data for a
given interval.

SPCL FCTN + “Down Arrow Key” (Software not available at this time)

This test function tests the linearity of the forward/reflected power and modulation meter. First
the Master Controller commands the Transmitter Control to increase the RF output power in
increments of 5 Watts starting at 10 Watts and increasing to 125 Watts. It then reverses and
decreases by 5 Watts until the transmitter returns to 10 Watts output. It then will start increasing
the modulation level by 5% from 0 to 95%. The modulation then returns to 0% and the unit goes
back to power increase and decrease.

7 Operational Checks

At the heart of the SE series system is a class D Power Amplifier that operates through a low pass
filter, with RF sourced from a Direct Digital Synthesizer (DDS). The imbedded microprocessor
lends itself nicely to automatic adjustment of system operating parameters. However to ensure
proper operation, verification with calibrated test equipment is required.

7.1 Test Equipment Required

3 1/2 digit digital multi-meter (DMM), calibrated

dual trace oscilloscope, calibrated

frequency counter, calibrated (± 1 Hz accuracy)

250 Watt, 50 Ohm non-reactive dummy load

7.2 Dummy Load Hookup

Connect a 250 Watt, 50 Ohm, non-reactive dummy load to the RF output jack (J50), an N Type
RF connector, on the bottom of the enclosure.

7.3 Power Up

Switch the AC switch (S2) to the ON position.

7.4 Power Up Verification

Observe the following sequence of Front Panel LCD displays:
