Chapter 2: Health & Safety warnings
2 Health & Safety warnings
When working on Kelvin Hughes equipment, operators, engineers and agents are expected to work
within the health and safety guidelines noted in the handbook, as issued by their respective employer
or as stated by site regulations, shipyard or vessel owner.
Risk assessments of a working area must be undertaken prior to commencement of any work and
must be regularly reviewed.
2.1
Hazards
ELECTRICAL HAZARDS:
Some equipment does not have safety interlocks fitted.
Lethal single and three phase AC and DC voltages may be present when units are open
and exposed.
Before accessing any internal parts, ALL power sources to the equipment must be fully
isolated; this must include the isolation of all UPS supported supplies to the system.
MAINS VOLTAGES:
All Kelvin Hughes equipment is supplied with mains input voltage set for 220v, 50/60 Hz
ac unless otherwise stated on labels attached to the equipment.
WARNING: Some equipment contains materials which may produce toxic fumes if burnt.
Beryllium warning: The SharpEyeTM X and S band transceivers mounted within
the SBS-800 series are factory sealed units which contain no field serviceable
parts. The SharpEyeTM transceivers must not be dismantled in the field as some
components within the factory sealed processor contain Beryllium which is
hazardous to health.
Class 1 laser product: There is a class 1 laser within the sealed SharpEye
transceiver processor which can represent a risk if the processor is
dismantled.
When fitted, the LAN fibre optic cable that connects to the SharpEye TM
transceiver and the to the MISM type 5 modules within the radar distribution
unit is considered as a class 1 laser.
2.2
Antenna rotation warning
ANTENNA ROTATION SAFETY NOTICE:
When single and three-phase power is connected to the system and switched ON, the
antenna will rotate immediately regardless of the RUN command status.
Use the antenna rotation keyswitch or man aloft safety switches to stop antenna rotation
in an emergency.

Chapter 2: Health & Safety warnings
2.3
Radiation hazards
Radiation hazard: non-ionising
Avoid exposure to the main beam of a stationary radar antenna.
Avoid standing closer than 2 metres from the central front face of the antenna.
Users of cardiac pacemakers should be aware of the possibility that radio frequency
transmissions can damage some devices or cause irregularities in their operation.
Anyone using such devices should understand the risks present before exposure.
2.4
Microwave radiation levels
The Council of the European Union Recommendation 1999/519/EC (Annex III table 2) specifies the
maximum RF non-ionising field strength (power density) safe range for human exposure averaged
over a six minute period as 10W/m in a frequency band of 10 to 300GHz.
Calculations for all SBS-900 systems show that the rotating antenna safe distance is within the
antenna turning circle although KH do not recommend any personnel to be in close proximity to a
rotating antenna due to RF exposure and the high risk of injury that can be caused by a rotating
antenna.

The safe range for a non-rotating antenna is far greater due to the lack of averaging but this is not a
permitted operational mode and the system includes interlocks to prevent this mode of operation for a
prolonged period.
Note: 5m of waveguide is assumed.

2.5
Working aloft
SAFETY ALOFT:
When working aloft or near any radar scanners, moving or RF radiating equipment, ALL
power sources to the platform and equipment must be fully isolated.
Before working aloft ensure someone in authority or at ground level knows of your
intentions and ensure that suitable clear warnings are in place.
Ensure all means of access aloft are secure and beware of wet or slippery ladder rungs
and working areas.
All working at height health and safety requirements and procedures, including the
inspection and use of personal protective equipment (PPE), must be adhered to at all
times as advised and required by your employer, site regulations, shipyard or vessel.
2.6
Man aloft switch/ antenna isolation.
Antenna rotation and transmission can be inhibited via a Man Aloft Switch (MAS) or an rlXn geTafVX\iXe
SharpEyeTM transceiver technology radically departs from conventional marine navigation transceivers
through the transmission of low power RF pulses and application of pulse compression and Doppler
techniques. The technology benefits from the following:
' Solid state transmitter for high reliability
' Dynamic range of 126 dB (including sensitivity
time constant (STC) & pulse compression gain)
' Digital pulse compression
' Minimum discernible signal (MDS) of
-125dBm
' Receiver noise figure <5.5dB
' Internal monitoring, no external components
required to monitor operation
' Pulse Doppler processing for improved rain
and sea clutter rejection
' Range discrimination: 7.5nm (24nm) and
15nm (48nm)
Solid state technology:
Solid state transistors obviate the need for a warm-up time. When the
Radar Distribution Unit is switched ON the SharpEyeTM is powered.
When a Run command is received by the transceiver, it is ready for
transmission within 40 seconds.
Output power:
When transmitting, the amplifiers generate a nominal peak power of
170Watts with a maximum duty cycle of 13% at the transceiver
output flange.
System monitoring:
Comprehensive built in test (BIT) facilities within the transceiver
provide on-line monitoring of the following parameters within the
transceiver:
' RF power
' Temperature
' Antenna system
VSWR
' Receiver
sensitivity
' Power supplies
' Antenna rotation
data
Should the system detect a fault condition which could lead to early
failure of the transceiver, i.e. a high VSWR, then the transceiver
switches to a low power state which permits transmission to continue
in the short term. The built in test monitoring also ionjonm [ â˘Kiq QE

The SBS-A1
A1-X Radar Distribution Unit (RDU) is a radar processing and distribution
unit that accepts radar video inputs from the external transceiver enclosure and
provides signal outputs in digital form.
The RDU accepts radar data via fibre optic cable or cable connection (cable on
SBS 900 51 only) and outputs digitised video including control and status data via a
LAN to the track extractor.
A Kelvin Hughes TCP/IP specific protocol is used based on the Asterix format.
The RDU also provides an interim two way serial interface for a range of service
displays which offer local control of the system for maintenance and monitoring
purposes.
Control modes: The RDU can be operated in either of the following modes
rd
Remote control
Local control
Optional
service display
In normal operation, the system is remotely controlled via a 3 party command & display
system or track extractor and WAN with the RDU acting as an interface.
Note: The infrastructure of the track extractor and WAN are not detailed in this handbook.
In local control, the system can be locally operated using controls
mounted on the front of the Radar Distribution Unit (RDU); controls
include:
- Local or Remote control selection.
- Local transceiver Run and Standby control.
- Viewing of status and BITE data on an integrated LCD display.
- Viewing and adjustment of system configurations.
A range of optional service displays are available which enables a maintainer to view,
control and display the radar locally for commissioning and maintenance purposes.
AC Breakers: To comply with CE and EN60950 requirements it is recommended that the AC
connections to the RDU are via clearly labelled, readily accessible disconnection
devices:
s:
- Single phase supply: Standard CE approved mains outlet sockets (not supplied).
- Three phase supply: Class B, red, 4 pole plug & socket (not supplied).
Antenna Rotation Safety Notice
Depending on the status of the safety switches, when three phase power is connected and
switched ON, the antenna may rotate immediately regardless of the RUN command status.

SBS-900 Shore Based Radar Systems
Chapter 5: Technical overview
AC requirements
Single phase: Two independent sources of UPS supported, single phase, 115/ 230VAC supply are
connected to the RDU.
The AC voltages are fed to an AC-DC power supply via user accessible breakers
located within the RDU. The internal power supply provides all the DC power
requirements of the RDU.
Switched AC supply is sent from the RDU to the DTX-A7 transceiver enclosure.
3-phase:
A 440VAC 3-phase input is fed via a user accessible breaker to an internal static
inverter. This generates and controls the three phase requirements of the turning
mechanism solution.
Caution: When the three phase supply is connected and switched ON, the inverter
unit is powered and sends three-phase voltages to the antenna motor which may
rotate immediately (see safety switches).
Safety switches: A normally closed safety current loop is provided for the serial connection of safety
switch contacts including an external Man Aloft switch.
Antenna rotation switch: An Antenna Rotation safety keyswitch
is provided on the RDU and is part of the safety current loop. This
switch can be set to OFF, removed and retained by the
maintainer for safety.
Man Aloft Switch (MAS): An externally mounted switch that can
be set to Free (rotate) or OFF.
When either the Antenna Rotation or Man Aloft switches are set
to OFF or if the safety current loop is broken/ open, the single and
3-phase AC supplies from the RDU to the transceiver enclose
and gearbox are isolated thereby stopping Antenna Rotation and
system transmission.
RDU Antenna
Rotation switch
External Man Aloft
Switch
Security Switches: There is also provision for an optional set of normally closed Antenna Platform
and a Hut Door switches that are used for monitoring purposes only. These switches
do not isolate or control any part of the system, when fitted and enabled, the systems
report the status of these switches to the RDU.

Chapter 6: Local operation instructions
Transceiver operational states
The following table shows the various operation states of the X or S-band SharpEyeTM transceivers
within the DTX-A7 transceiver enclosure:
Operation state
Description
OFF
Power is not applied to the transceiver and it is switched OFF.
On completion of initialisation the transceiver switches to standby or, if any of
the self-test checks fail, to fault state.
Initialise
The system initialisation typically takes 30 to 40 seconds after which time the
system becomes available for operation.
In standby the transceiver establishes communication with the Radar
Distribution Unit and reports its status.
Standby
The transceiver receives and acts on commands from the RDU.
In Standby the antenna rotates but the system does not transmit.
When a RUN command is received from the Radar Distribution Unit and
azimuth and heading line signals are present, the SharpEye TM transmits.
The transceiver initially outputs at low power. The radar returns are then
processed enabling the VSWR to be checked without the risk of damage to the
transceiver.
Transmit
If the VSWR is within limits then the transceiver automatically switches to full
power.
If the VSWR is high, indicating an antenna fault, a warning message is sent to
the Radar Distribution Unit and the transceiver enters the degraded Low
Power state.
Degraded
(Low power)
The transceiver continuously runs background performance checks on forward
power, reverse power, receiver sensitivity and temperature. If any of these
parameters falls outside predetermined levels a warning message is sent to
the Radar Distribution Unit indicating the nature of the fault.
The transceiver continues to operate, but with reduced performance and
functionality.
If the performance or functionality is degraded such that the transceiver cannot
operate it enters the fault state and a fault message is sent to the display
equipment.
Fault
The transceiver stops radiating RF and there is no video output to the Radar
Distribution Unit.
A spurious fault may be cleared by re-powering the equipment.
Communication
error
If communication is lost between the Radar Distribution Unit and the
TM
SharpEye , the RDU reboots the SharpEye leading to a potential 60 second
gap in coverage.

TX Power
The output power of the SharpEye
TM
transceiver can be switched between High (default) and Low.
TM
High power:
The SharpEye transceiver transmits at full power.
This is the recommended default setting.
Low power:
Low power is used in close waters or in a high clutter environment where a high
output power may produce excessive unwanted reflections from buildings, bridges
and vessels.
The transceiver will utilise the standard frame pattern but with output power reduced
to less than 40W.
Caution: As a result of reduced output power, range performance will be reduced
and the system may not meet the expected operational detection performance.
When low power is selected, a low power status is automatically generated to advise
the operator that the system is operating at a reduced output power.
Where the SharpEyeTM detects a VSWR or a high temperature within the transceiver
the system automatically switches to low power mode and generates system alarms.

Chapter 7: Remote operation instructions
Transceiver operating states
The following table shows the various operation states of the SharpEye TM transceiver.
The antenna will rotate regardless of the transceiver state.
Operation state
Description
OFF
Power is not applied to the transceiver which is switched OFF.
On completion of initialisation the transceiver switches to standby or, if any of
the self-test checks fail, to fault state.
Initialise
The system initialisation typically takes 30 to 40 seconds after which time the
system becomes available for operation.
In standby the transceiver establishes communication with the Radar
Distribution Unit and reports its status.
Standby
The transceiver receives and acts on commands from the RDU.
In Standby the antenna rotates but the system does not transmit.
When a RUN command is received from the Radar Distribution Unit and
TM
ACP/ARP signals are present, the SharpEye transmits.
The transceiver initially outputs at low power. The radar returns are then
processed enabling the VSWR to be checked without the risk of damage to the
transceiver.
Transmit
If the VSWR is within limits then the transceiver automatically switches to full
power.
If the VSWR is high, indicating an antenna fault, a warning message is sent to
the Radar Distribution Unit and the transceiver enters the degraded Low
Power state.
Degraded
(Low power)
The transceiver continuously runs background performance checks on forward
power, reverse power, receiver sensitivity and temperature. If any of these
parameters falls outside predetermined levels a warning message is sent to
the Radar Distribution Unit indicating the nature of the fault.
The transceiver continues to operate, but with reduced performance and
functionality.
If the performance or functionality is degraded such that the transceiver cannot
operate it enters the fault state and a fault message is sent to the display
equipment.
Fault
The transceiver stops radiating RF and there is no video output to the Radar
Distribution Unit.
A spurious fault may be cleared by re-powering the equipment.
Communication
error
If communication is lost between the Radar Distribution Unit and the
TM
SharpEye , the RDU reboots the SharpEyex leading to a potential 20
second gap in coverage.

Measuring the three phase output
The three phase output of the inverter is a pulse width modulated (PWM) sine wave which cannot be
accurately measured using a standard DVM (Digital voltmeter).
If measured the 440VAC output will actually measure approximately 220VAC +/-10% depending on
the multimeter being used.
Completion of task
On completion of the inverter commissioning, switch the system OFF and reconnect the three-phase
output to the antenna motor (PL4 on the base of the RDU).
Switch the system ON and ensure that the inverter is operational and that the antenna is rotating.
When operational, the inverter will have the following status:
' The charge light will be ON
' The Run indicator will be ON
' The display will show 22Hz for 20RPM systems and 44Hz for 40 RPM systems.
With the inverter ON and the antenna rotation and man aloft switches are in the FREE position the
antenna should rotate.
Remote control operation
When the inverter and fan replacement is completed, ensure that the Local/ Remote switch on the
Radar Distribution Unit (RDU) is in the Remote position.
Ensure that the system can be remotely controlled and is fully operation.

10.2 Standard systems overview
10.2.1 Power connections
AC/ DC
power:
RDU:
Two sources of UPS supported single phase AC and a separate
three phase supply are connected to the RDU.
Internal breakers and contactors control the AC voltages to the rest
of the system.
An internal power supply generates all the DC rails required by the
RDU.
Transceiver
Enclosure
Single or dual (system dependent) sources of AC power are
connected from the RDU and are internally protected and switched
by the use of breakers.
Internal power supplies generate all the DC rails required by the
transceiver enclosure.
A separate DC rail is provided to power the ACP/ ARP encoder in the
antenna sub-system.
Antenna subsystem
The antenna motor is driven by the three phase output of the RDU
(see below).
A DC rail from the transceiver Enclosure is used to power the ACP/
ARP encoder.
Three phase measurement:
The three phase output of the inverter is a pulse width modulated
(PWM) sine wave which cannot be accurately measured using a
standard DVM (Digital voltmeter).
If measured the 440VAC output will actually measure approximately
220VAC +/-10% depending on the multimeter being used.
10.2.2 Over current protection devices
Kelvin Hughes gearboxes:
There are no fuses or breakers located within the gearbox for the AC
supplies to the Kelvin Hughes gearbox.
The safety mechanisms within the Radar Distribution unit and
transceivers which include the Man Aloft Switch and Antenna
Rotation keyswitch should be used to isolate the system.
See section 9.3 page 87 onwards for full details.

10.2.3 Service door removal
Service Door removal: The service door on the turning mechanism must be opened to gain access
to the electrical terminations for the ACP and ARP signals and for connecting
the flexwell in S-Band systems (X-band systems connect externally).
Opening the service access door is not required for any other reason.
Caution: The service access door is heavy, care should be
exercised when removing and handling the door.
The door removal process is identical for both X and S-band systems
Safety clips:
There are two safety P-clips that must be
removed to detach the door.
These clips MUST be re-attached when
replacing the service door.
Safety lanyard:
To prevent a drop hazard, the door is fitted with an internally mounted safety
lanyard. If required this lanyard can be unclipped and the door carefully
lowered to a safe position.
Door bolts:
There are nine M8/ 13mm bolts restraining the door. Care should be taken
when removing these bolts are they are NOT captive.
Release points:
The door is mounted on two locating
lugs. It may be necessary to gently
leaver the door open using the two
door release points marked on the
door.
Care should be taken to ensure the
paint is not damaged whilst removing
the door.
Replacement:
Prior to replacing the door, the following should be checked:
- The system is fully isolated from all sources of AC power
- Ensure the door is correctly located on the mounting lugs and that the
restrain clips have been replaced.
- Pay attention to the safety lanyard as this can easily become trapped in
the door when being closed.
- Tighten all bolts on the main door, the 3-phase motor cover and cable
glands ensuring a full waterproof seal is achieved.
- To prevent corrosion, any chipped or damaged surfaces must be painted
with polyurethane paint.

10.3.5 ACP/ARP encoder
GTX-A188
Optical quadrature azimuth and heading
line encoder
The sealed ACP/ ARP encoder is situated inside the gearbox housing and is located around the
rotating joint shaft. It outputs 1024 pulses (two azimuth streams 90deg phase shifted and two inverse
azimuths) per revolution.
The encoder also outputs a heading line pulse and an inverse heading line pulse for each revolution
of the antenna. The azimuth, heading line output signals and DC power input are connected to TB1
which is internally located in the base of the gearbox.
The encoder is supplied with +15V DC supply from the transceiver enclosure.
The Quadrature ACP comprises of two 90° phase shifted square wave pulse trains ACP1 & ACP2
whose frequency is dependent on antenna rotation rate.
1024 ACP pulses are required per 360° antenna rotation from each pulse train.
ACP2 lags ACP1 by 90° for an antenna rotating clockwise when viewed from above.
The output pulses have an amplitude of +15V.
Each rising or falling edge is decoded from these two pulse trains to provide 4096 ACPs per antenna
revolution.
The ARP pulse width is required to be equal to at least one 4096 decoded period but does not have to
have any specific timing in relation to ACPs i.e. it can be asynchronous w.r.t ACPs.

10.7.7 DTX-A295 quadrature buffer PCB
The DTX-A295 converts pulsed 90:1 or 180:1 Azimuth and HL inputs into 4096 Quadrature differential
signals. The board uses a small processor to multiply the incoming Azimuth pulses in accordance with
the rate of turn detected.
Inputs are opto-coupled for signal integrity and isolation purposes.
The PCA is powered by the power supply located within the transceiver enclosure and can operate
from an input of between +12V to 24VDC. The PCA generates all required DC rails from the input
voltage with all rails being isolated (including GND) from the input supply.

10.7.8 SBS-A126 Switch Control & BITE PCA
10.7.8.1 Overview
The Switch control and BITE PCA system is a non-critical link in the system where one or two
SharpEyeTM transceivers are located within the same enclosure and share a single antenna subsystem.
The role of the Switch control and BITE PCA is to:
Derive power for the +5V advanced antenna sub-system ACP/ ARP encoder.
Derive power for the +28V waveguide switch.
Provide power to the +15V Standard antenna sub-system ACP/ ARP encoder.
Monitor and digitally transmit voltage levels via RS422.
Monitor system states and transmit via RS422 to the RDU.
Monitor enclosure temperature using on-board sensor and transmit via RS422 to the RDU.
Receive commands via RS422 and activate waveguide switch and polarisation switch.

PCA failure:
If a failure of the Switch control and BITE PCA should occur then the default
transceiver (Tx A) will still be able to operate. Manual control of the waveguide switch,
and therefore Tx B, is still available.
Start-up:
During start up, the waveguide switch is to be set to Tx A, and the polarisation switch
to horizontal. Once the communication between the PCA and the RDU has been
established and start-up checks are complete, then the processor takes over the
control of the waveguide and polarisation switches as commanded by the RDU.
Power:
The PCA is powered by the 15VDC output of the power supply. When either PSU A
(single transceiver systems) or PSU B (dual transceiver systems) is powered, the
PCA is powered and operational.
On board DC-DC conversion provides all the power requirements of the PCA.

Chapter 10: Corrective maintenance
Waveguide switch selector: (Dual transceiver systems only) Two +28V outputs provided for the
waveguide switch control. One output will cause the waveguide switch to set to
transmitter A, and the other sets the waveguide switch to transmitter B. The default
position is transceiver A. The selector switch defaults to the A position if there is a
fault in the communications to the PCA.
Waveguide switch tellback: (Dual transceiver systems only) The current position of the waveguide
switch is sensed and reported back to the RDU.
Motor on:
Two motor ON signal inputs are monitored, one from each of the transceivers. Each
has a signal level of 15V DC when the motor is on, and 0V when the motor is off. The
status of the motor used to indicate which transceiver is running but does not control
the motor ON/ OFF function.
Blanking:
Two blanking inputs are to be received by the card. A blanking input is received for
each transceiver via a 75Â SMB connection.
ACP/ARP:
The Azimuth Clock Pulse (ACP) and Azimuth Reset Pulse (ARP) are distributed from
the encoder to both SharpEyeTM transceivers, the signals are also transmitted to the
RDU. The signals are not amplified and continue to operate in the event of a power
failure on the board.
Power fan sensing: Inputs receive, monitor and report the outputs (RPM) of the optional forced air
fans.

10.7.9 SharpEyen error messages
If a fault condition is detected within the SharpEye TM transceiver, a fault message is sent to the Radar
Distribution Unit and in certain conditions the unit switches to a degraded low power state of
operation.
The following is a list of possible alarm conditions that can occur within the SharpEye transceiver.
SharpEyeTM
error Message
Description
Rx sensitivity
If the minimum detectable signal rises above a pre-set level the transceiver
sends a receiver sensitivity warning message.
If the VSWR on the RF output is worse than 1.4:1 the transceiver sends an
antenna VSWR warning message and switches to the degraded Âfiq jiq_lÂ
state of operation.
VSWR
If the VSWR on the RF output is worse than 2.0:1 the transceiver enters fault
mode and is shutdown.
SYNTH
The synthesiser has not initialised correctly; cycling the power may clear this
condition (emergency stop).
Tx power
If the RF output power falls below 100W the transceiver sends an RF Power
LOW warning message and switches to the degraded Âfiq jiq_l state of
operation.
If the temperature of the RF power transistors in the transceiver exceeds a
jl_^_n_lgch_^ fcgcn+ nb_ nl[hm]_cp_l m_h^m [h â˘ip_l-n_gj_l[nol_ q[lhcha ni nb_
Radar Distribution Unit and switches to the degraded Âfiq jiq_l state.
Over temperature
If the temperature exceeds a further pre-set limit the transceiver switches to
the fault state and transmission is stopped.
As the temperature returns to within the predetermined limits, the transceiver
returns to the degraded state and then to normal transmit operation.
Turning info lost
If the antenna stops rotating when not commanded to stop, a warning
message is sent to the display equipment and the transceiver switches to the
fault state and transmission is stopped.
ARP/HL not
detected
If an azimuth or heading line pulse is not detected, a message is sent to the
transceiver and for safety reasons transmission is stopped within 60 seconds.
Azimuth status
(1)
Antenna rotation is checked for clockwise rotation (viewed from above). If anticlockwise rotation is detected, a message is sent and transmission is stopped
within 60 seconds.
Azimuth status
(2)
If missing pulses between heading lines are detected, a message is sent and
transmission is stopped within 60 seconds.

SharpEye
error Message
Description
FPGA2 failed
If the transceiver detects a hardware fault, it sends a warning message to the
display equipment and switches to the Degraded state of operation.
The transceiver continuously runs background performance checks on forward
power, reverse power, receiver sensitivity and temperature. If any of these
parameters falls outside predetermined levels a warning message is sent to
the Radar Distribution Unit indicating the nature of the fault.
Degraded
(Low power)
The transceiver continues to operate, but with reduced performance and
functionality.
Caution: As a result of reduced output power, range performance will be
reduced and the system may not meet the expected operational detection
performance.
If the performance or functionality is degraded such that the transceiver cannot
operate it enters the fault state and a fault message is sent to the display
equipment.
Fault
The transceiver stops radiating RF and there is no video output to the Radar
Distribution Unit.
A spurious fault may be cleared by re-powering the equipment.
Communication
error
If communication is lost between the Radar Distribution Unit and the
SharpEyeTM , the RDU reboots the SharpEye leading to a potential 60 second
gap in coverage.

10.8.10 NTX-A477-1 radar I/O module
Modular interface system module (MISM) Type 9 (radar I/O module Mk 2)
Part number NTX-A477-1
Backplane locations: A3 (service display output)
A4 (Track extractor output)
B3 (Spare output)
Overview:
The radar I/O module interfaces the following signals with the backplane:
- Analogue radar input (video, sync, azimuth and heading line)
- Analogue radar output (video, sync, blanking, azimuth and heading line)
- An auxiliary video channel is used for an ESM Blanking pulse input from
the Tx/ Rx
- A blanking output is used to output an ESM blanking pulse
The board is controlled by the backplane which selects the radar input from
one of many input channels and route the data to the output channels using
the video switching circuitry.
Video IN:
Radar video is received on SKA at +1.0V to +6.0V peak-to-peak with an input
impedance of 75ohms and is routed to the radar I/O PCB.
The video is applied to an operational amplifier which provides a 2.0V peakto-peak output which is dropped to 1.0V peak-to-peak (TP5) for application to
the backplane. The video amplifier gain and offset is manually set and
controlled from the backplane at 1.0V peak-to-peak ensuring the correct input
level. The offset circuit allows the amplifier to compensate for any DC offset in
the input signal, thus providing the correct signal level to the backplane.
LED D5 flashes when the video input is detected by the backplane.
Video OUT:
Video out of the radar I/O PCB is sent to the backplane terminated at 75ohms
to provide an output of between +1.0V to +5.0V peak-to-peak to SKD which
can be measured at TP9.
Sync IN:
Radar sync is input on SKB at 3.0V to 15V pulses and an input impedance of
75ohm and is routed to the radar I/O PCB. The sync is processed and passed
via a high speed differential comparator to the backplane as an LVTTL signal
(TP8).
LED D4 is lit when the sync input is detected by the backplane.
Sync OUT:
The sync output from the radar I/O PCB is amplified by to provide sync
pulses between 3.0V and 14V on SKE and TP11. The sync level is controlled
from the backplane and an operational amplifier.
Aux video/ blanking: The auxiliary video input/ blanking from the radar I/O PCB is amplified to
provide blanking pulses between 3.0V and 14V on SKF and TP10. The
blanking pulse level is controlled from the backplane and an operational
amplifier.
Azimuth:
The Azimuth inputs (Az1 and Az2) utilises the same circuitry as for a pulsed
format, but are all terminated by a link selectable 120| resistor (links 1, 2 & 6
for RS422). Azimuth can be received as pulsed, quadrature, RSS422 or
+5.0V to +17.5V peak-peak (adjustable during system configuration/ factory
set to +15V).

The heading line utilises the same circuitry as for a pulsed format, but are all
terminated by a link selectable 120| resistor.
ARP/ Heading line signals can be received as pulsed, quadrature, RSS422 or
+5.0V to +17.5V peak-peak (adjustable during system configuration, factory

10.8.13 VDR-A121-3 status and control PCB
The Status and Control PCB Assembly (Front panel)
provides indication of the unit status by means of an
LCD display and a set of LEDs, and provides control
of the unit functions by means of four pushbutton
switches.
The unit is interfaced via a bi-directional RS232 serial
data link on PL1 to SK3 on the backplane.
The four switches are momentary action pushbutton switches. The lower right switch also contains an
integral LED indication, which may or may not be used depending on the requirements of the parent
equipment.
When a switch is pressed the interface to the microprocessor is pulled down to ground and this is
detected by the microprocessor. The switch functions and LED display are determined by the
configuration software, not by the on-board software.

10.8.17 Safety and security switches
Safety switches
The safety switches form part of a safety current I-loop. When either the Antenna Rotation or Man
Aloft switches are set to OFF or if the safety current loop is open, single and 3-phase AC supplies to
the transceiver/ gearbox are isolated thereby stopping antenna rotation and system transmission.
Antenna rotation Key switch

The Antenna Rotation keyswitch is located on
the front door of the RDU.
An externally mounted waterproof masthead
switch.
This switch can be set to OFF and the key
removed and retained by the maintainer.
This switch can be set to FREE or OFF

Chapter 10: Corrective maintenance
Security switches
Connections are provided on the RDU for two security switches. The system reports the status of
these switches to the command and display system, track extractor or optional service display.
The normally closed (N/C) switch inputs switches are for monitoring purposes only and do not isolate
or control any aspect of the system.
Where fitted, these switches must be enabled during setting to work of the system.
Two switch connections are available as follows:
SKM / Ant Platform:
This is designed for a security switch on the gate or access point to the
antenna platform.
SKN / Hut door:
This is designed for a security switch on the equipment building or hut access
door.
Additional security switches can be serially added using a junction box (not supplied) in a similar
fashion to the security switches as shown on the previous page.
Antenna platform/ Hut door switch: Normally closed (N/C) switch returning a voltage back to
RDU.
