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
ELECTRICALHAZARDS:
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 otherwisestated on labels attached to the equipment.
WARNING: Some equipment contains materials which mayproduce toxic fumes if burnt.
Beryllium warning: The SharpEyeTMX and S band transceivers mounted within
the SBS-800 series are factory sealed units which contain no field serviceable
parts. The SharpEyeTMtransceivers 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
transceiver and the to the MISM type 5 modules within the radar distribution
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.
TM
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/m2in 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.

Chapter 2: Health & Safety warnings
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
intentionsand ensure that suitable clear warnings are in place.
Ensure all meansof access aloft are secureand 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 r<agXaaT IAAAeXXs keyswitch. These mechanisms can be used bya person who sees a potential hazard such as a
loose halyardand decides to protect the antenna.
When activated, the reason for loss of turning is detected by the system and is reported to the local
and remote users
Safety switches
The Antenna Rotation keyswitch is located on the door of the internally mounted
Radar DistributionUnit (RDU)
Antenna
Rotation
keyswitch
Man aloft
switch
(MAS)
The Man Aloft switch, Motor ON/ OFF and Antenna Rotation keyswitch form partof a safety current
loop. This safety loop is purely hardware (no software), when the current loop is opened, AC mains
supplies to the transceivers and antenna inverter are switch OFF by use of contactors.
The key for the RDU keyswitch is captive when set to Free (enable rotation) but
can be removed when the keyswitch is to OFF.
When in the OFF position all single and 3-phase AC power to the antenna and
transceiver is isolated thus stopping antenna rotation and transmission.
The key should be removed and retained by the person who intends to enter the
potentially hazardous volume of the rotating antenna.
The man aloft switch (MAS) is designed to be installed such that it is still viewable
for the person who is carrying out maintenance tasks.
Vb_h m_n ni nb_ •OFF jimcncih the transceiver/ gearbox is isolated from all single
and 3-phase AC power thus stoppingthe antenna rotation and transmission.
Kelvin Hughes recommends that the key switches noted above are used in conjunction with the man
aloft switch but also recommend that radar users carry out a safety assessment and risk mitigation
procedure in terms of interlocks prior to approving any work on the equipment.
Full details on isolatingthe systems from the AC supplies can be found in the planned maintenance
section of the relevant systems Operator & Maintenance handbook.

5.10 Transceiver enclosure
The DTX-A7 is a range of externalmounted
waterproof enclosures that contains the relevant X or
S-Band SharpEyeTMtransceiver(s), an azimuth signal
interface, system power supplies, a waveguide switch
(where required) and an RF connection to the antenna
sub-assembly.
The system is designedto beexternally mounted and
is convection cooled by the use of heatsinks and four
wind turned rotary ventilators mounted on top of the
assembly.
For areas operating in high ambient temperatures
additional powered cooling fans can be fitted as an
Connection to antenna
The system is connected to the antenna sub-system via a bespoke waveguide connected to the top of
the system. The waveguide/ flexwell is supplied preassembled with a static desiccator drying unit (55100-0436-001).
Example of a DTX-A7-3 shown withaccess doors
removed for clarity
Turning data (ACP/ ARP) is interfaced to the enclosure from the turning unit via cable connections.
NOTICE: Maximum flexwell/ waveguide distance
The maximum flexwell/ waveguide run between the DTX-A7 transceiver enclosure and the
antenna sub-assembly is 5 metres.
Waveguide dryer: A static desiccator is supplied pre-assembled onto the
waveguide as part of all SBS-900 systems.
The unit is a totally passive device and requires no electricalpower.
It connects directly into a gas inlet port that forms partof the flexwell/ waveguide
assembly.
The clear wall of the unit allows visual inspection of the desiccant condition. As
moisture is adsorbed the colour will change from deep blue to pink/white. When
A pressurised waveguide dryer (SBS-A131-1) is also available as an option.

Connection to Radar Distribution Unit
Data Signals: The following signals are transferred between the DTX-A7 enclosure and the Radar
Distribution Unit:
' Digital signals in the form of radar video, display sync, ACP and ARP
' System control, status and BITE data
' Blanking signals
Connectionsbetween the two units are via:
' SBS-900-1, -2, -3 & -4: Fibre optic cable
' SBS-900-51: Cable connection
Power: The enclosure is AC powered and controlled bythe Radar Distribution Unit. In single
transceivers a single AC supply is provided, in dual systems two AC supplies are
provided (one for each transceiver).
Internal AC-DC power supplies provide all the internal DC power requirements of the
enclosure. A DC supply is also provided to power the ACP/ ARP encoder in the
antenna sub-system.
- For Standard systems sub-systems the encoder supplyis +15VDC
- For Advanced antenna sub- systems the encoder supply is +5VDC
Over current protection devices: The Transceiver enclosure is fitted with internal breakers for the
AC supply(s) to the enclosure.
- MCB1 isolates the AC supply to the left hand side of the enclosure.
- MCB2 isolates the right hand side of the enclosure.
All breakers must be in their OFF position before commencing any form of service or
maintenance work on the system.
Access: Access to the unit is via two lockable(8mm hex key), waterproof doors mounted on
the front of the unit.
Location: The DTX-A7-X waterproof enclosure is designedto be externally mounted located
within 5 metres of the gearbox/ antenna turning unit.
Interlocks: Maintenance and ENCOM safety switches are provided via an Antenna Rotation
keyswitch fitted on the RDU and an externally mounted Man Aloft switch
Breakers for the AC input are located within the transceiver enclosure.
If no azimuth (rotation) is detected, the SharpEye will automatically switch to standby
within 60 seconds of signal loss.

Chapter 5: Technical overview
K[Tec>lXn geTafVX\iXe
SharpEyeTMtransceiver 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 compressiongain)
' Digital pulse compression ' Minimum discernible signal (MDS) of
-125dBm
' Receiver noisefigure <5.5dB ' Internal monitoring, no external components
required to monitor operation
' Pulse Doppler processingfor improved rain
' Range discrimination: 7.5nm (24nm) and
and sea clutter rejection
Solid state technology: Solid state transistors obviate the need for a warm-up time. When the
Radar Distribution Unit is switched ON the SharpEyeTMis 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 ' Antenna system
' Temperature ' Receiver
' Power supplies
' Antenna rotation
SBS-900 Range:
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 [ •Kiq QE
