SL-PEL Series
Sectored Port Entry Light
CONSIDERING TOWER RIGIDITY:
It is important to remember that the PEL sectored light has a precision of typically one min of arc and
any structure or mounting bracket used to support it must have that rigidity in terms of horizontal twist.
When considering the PEL’s mounting, the following items need to be reviewed if these structures will
be utilised: size of daymark, its age, ladder and platform access. In addition, while the light-weight
nature of the PEL will permit mounting on a tilted column, its slender nature and the need to align the
light when fully erect precludes its use.
The structure must therefore be able to support the following: the PEL itself, its required power supply,
any daymarks, and at least two maintenance staff without twisting in heavy gale force winds (up to 100
MPH).
CONSIDERING HEIGHT:
The height of the structure above chart datum must suit not only the tallest bridge height but also
the smallest bridge height during all states of the tide, and not only at the extremity of the channel,
but from the nearest point of exit or to that point where other port lights take over. This is a function
of the vertical divergence of the PEL and the centre line of the PEL can be arranged to point into
mid-channel, ensuring that the top of the beam to 50% equates to the tallest bridge height on the
largest tide. The reverse is true for the smallest vessel on the lowest tide and the point of exit. Sealite
engineers can offer advice in this regard upon request.
CONSIDERING TOWER COLOUR:
In most cases the PEL sector light will supplement an existing mark which may be a well-recognised
building, solid stone tower, or steel lattice construction. It could be that the nature and type of use
of this structure and surrounding background has changed over the years. While the PEL itself will
enhance and improve the structures identication in day time, it is important to review.
Perhaps the original building or structure was white when viewed against a jungle or sloping green
elds and with modern build up around the port it is now surrounded by concrete buildings or tanks.
During project review and implementation a simple inbound trip on the pilot or suitable vessel whilst
taking pictures at one mile intervals will reveal many simple opportunities for further enhancement.
Changing the tower colour or adding colour to the structure will assist the mariner in improving its
recognition. It is not essential to retain its original colour just because it has always been so.
INSTALLATION GUIDE
Thank you for choosing a Sealite SL LED series precision sector light. The unit has been pre-
programmed to suit your order which includes the colour of each sector. All other parameters are user
programmable. These parameters have been factory set.

CONSIDERING DAYMARKS:
While the PEL will be used as a single station aid, this does not mean that daymarks are no longer
required. For example, a steel lattice tower or single column pole will be almost invisible from seaward.
By cladding the tower in vertical or horizontal boards its recognition will improve in daylight hours. Its
colour should be in contrast to the normal back ground.
If this is an established approach bearing, most pilots and masters will have their own “back-marks” to
create a natural leading line if no back-mark exists. This could be a church or mosque spire, telecoms
tower, natural dip in a mountainous sky line, or even a mountain or hill itself. It could however just be
another building.
Natural marks or buildings owned by others are unable to be enhanced, however buildings owned by
the ports themselves can have daymark squares painted on their edges to improve the bearing line
recognition. Again, by taking a series of pictures on the approach line can improve this process and
Sealite engineers can offer recommendations.
These additions and suggestions to the project are usually very cost-effective in enhancing the PEL
performance and an age old proven method of assisting the mariner which can sometimes be overlooked
when considering the overall project.
CONSIDERING TWIN OR LEADING MARKS:
While the PEL is predominately used as a single station aid, they should be retained as an unlit structure
to assist day use if a “back-mark” or “front-mark” exists where the bearing line is still relevant, provided
there is no signicant cost to its retention.
If it is the “back-mark” that is to be retained, consideration should be given to supplementing this
mark with an omni-directional light synchronised to the PEL. Even if the channel has been extended,
destroying the sensitivity of the system, keeping a light synchronised with the sectored light is another
way of maintaining the approach to the bearing line. This is true of whether the structure is to be lit or to
remain unlit.
The “series of pictures” method can be extended to include approach to the bearing line noting beacons
and buoys used in the passage of which further mention will be made later in this manual.
Improving traditional leads with a PEL

SL-PEL Series
Sectored Port Entry Light
NIGHT-TIME USE:
Usually one of the main reasons a port considers upgrading its leading line is due to a growth of port
infrastructure around the bearing, making it impossible for the mariner to pick out the leads. Again, a
photographic record of an approach noting possible interfering lights at night time will help to enhance
the new system. A simple addition of ood lights or an adjustment of current ood light direction could
improve recognition signicantly. This exercise is also useful when determining the level of automatic
night dimming which will be discussed later in the manual.
DAY-TIME USE:
Providing a light for day use is expensive in terms of the power required to generate bright lights which is
visible in daytime. Reference to the approach bearing will determine if this is to be directly in a rising or
setting sun. Any viewing in this direction without the assistance of a dark skyline will reduce the range of
the light. The higher the mountain range or building behind the light which will create a large silhouette
will increase the range the light can achieve. Summer and winter variations of the sun’s position relative
to the bearing angle should also be considered.
It is recommended that during the project’s engineering stage that a series of pictures are taken of the
ship’s view during approach during the time of a rising or setting sun, or any other harsh conditions to
make a valid assessment of light intensity required. Sealite engineers may also be consulted for their
recommendations.
DAY AND NIGHT USE:
If the light is to be used in both day and night time applications it will most certainly require to be dimmed
for night use. This is an automatic feature built into the PEL where the user can congure the intensities
to be set. Sealite engineers have created a programme supplied with the PEL which enables the
commissioning engineer to adjust this intensity via the USB port provided.
CONSIDERING SITE SELECTION:
If the project is brand new with a new bearing line and the Harbour Master or Pilots have a choice to
select the approach line over and above any geographical restrictions on the position of rocks or reefs, it
is a useful exercise to draw the “ideal approach line.” This could be angled to suit a particular approach
if vessels will always approach from a given direction. If from either Port or Starboard of the line then the
line will need to be centralised. However, if the approach for a given size of vessel is always from the
Port side of the bearing line then the line should be angled to diminish his course change. Amounts of
dredging (if required) is always an item to be taken into consideration in terms of cost.
Once selected, the extremity of the channel or to the edge of any rocks or reefs should be drawn on
either side of this bearing line. These lines should be extended back to shore or the location from which
the PEL will be driven. Once the points have been selected, the land or sea within these two vectors can
be reviewed for suitability. Points to be considered include:
1. Ownership of the land.
2. Background on the leading line.

SL-PEL Series
Sectored Port Entry Light
3. Obstructions in front of any position selected.
4. Height of that point naturally above Chart Datum.
5. Light pollution around this spot.
6. Any shadows which will affect solar applications.
Through a combination of suitability and cost implications a theoretical position can be determined and
proposed to dene safe passage through the channel and any obstacles. This latitude and longitude
point should be recorded and lled into the Sealite PEL Information Checklist and sent to Sealite to aid
discussions.
SUPPORTING AIDS:
Previously, Aids to Navigation (AtoNs) were considered stand-alone devices due to restrictions on
technology. With the improvements of radio and satellite communications however, it is now possible to
link these previous stand-alone aids. This is true for buoy synchronised channels and pairs of leading
lights, as well as channels and isolated buoys on leading line approaches.
It is now possible to select leads to be synchronised with specic beacons and buoys to increase the
mariner’s total eld of vision in one time during approach. By revisiting the ash characters of previously
isolated aids it is now possible to create better approaches and combine these isolated beacons and
buoys to the approach character of the leading or sectored light.
Here again Sealite can assist in offering recommendations to enhance the approach to the leading
bearing. There are distinct advantages in reviewing supporting aids to enhance the overall marking of the
port and to save on power consumption. This can help increase the range of these aids to offset the ever
increasing background lighting in a port.
COMMISSIONING THE PEL SECTOR LIGHT:
Prior to installation it is recommended that the relative position of the site be checked against both the
charts and other prominent navigation marks used around the port. These can be breakwater or quay
edges, and church spires or lighthouses which have specic points of sight (i.e.: wind vanes and masts).
These can be used to check the relative bearing angle to each other and ensure the proposed leading
line is correct.
It is not unusual to discover small inaccuracies of charted rocks or quay extensions from those currently
on the chart due to the date and accuracy of the most recent surveys.

SL-PEL Series
Sectored Port Entry Light
ALIGNMENT OF THE PEL SECTOR LIGHT:
While there is no best single method of achieving a commissioned alignment, there are many variants on
how alignment may be achieved. The PEL sector light is an accurate instrument but it should be noted
that the centre line of the beam is theoretical, and the only points of accurate reference are the edges of
the total beam (light cut off) or between colours. It is these reference lines which should be used to set up
the light and these bearing lines should be drawn on the chart and bearings noted.
Option 1 (Preferred method)
Refer to the chart and select known dened points on land at a distance of approximately 1/2 to 3/4 of
a mile from the sectored light. This may be the edge of a quay or rock with established beacon which is
identiable on the chart from which a distance to one of the bearing lines can be measured by tape over
land. This point can be determined prior to the installation and marked by a wooden peg or spray painted
spot on a rock or quay wall.
Option 2
If such a point is not available over land, the same can be achieved using a measure line of
Polypropylene oating rope which can be laid out from a small boat and held in tension in a given
direction previously determined from the chart.
Option 3
If none of the bearing lines make land fall or the distance from land is greater than 100 to 200 metres
then the operation of alignment must be conducted dynamically by boat with reference to a Theodolite
alignment. Method 3 will require the Theodolite to be set up at the base of the tower directly below the
light on the centre line of the theoretical bearing or on the balcony of the tower itself. It must be on the
centre line of the approach with reference to all other local marks.
Clear Line of Sight
The position selected must have a clear line of sight of the bearing lines on the day of alignment and not
be obstructed by any vessel.
Time of Alignment
The best time to align the light is when light levels are at their softest (early morning or dusk). Viewing the
light in the direction of a rising and setting sun should be avoided and a time selected where the tide suits
those marks which have been selected for reference. This is important in areas with high tidal ranges,
both for access to the mark and draft of the vessel (if used to get to the location).
Personnel required
At the reference point:
One competent observer with VHF radio or mobile phone who can communicate in the same language
as the commissioning technician without the need of a translator.

Latest products and information available at www.sealite.com
15
SL-PEL Series
Sectored Port Entry Light
If Method 2 or 3 is being used, a small motor powered boat with both helmsman and able-bodied seamen
to lay out the line and act as a safety man. The observer must be free of all duties and concentrate only
on reporting what he can see.
At the PEL:
One technician with VHF radio or GSM phone if methods 1 or 2 are being utilised.
If method 3 is being used, a skilled Theodolite operator with shared VHF radio.
Approximately 1 hour should be allowed for Method 1 and 2-3 hours for Methods 2 or 3 ensuring that all
operations are complete before the hours of darkness. All parties should gather for a discussion on what
is required of each person. It is recommended that the acceptance ofcer who will endorse the alignment
of the light is positioned at the light during alignment. They may verify the completed alignment from
seaward at a later time, however acceptance and verication shall be completed at the tower.
Alignment Procedure:
It is recommended that the lantern is set to a xed ash character (00) and 100% intensity with the PEL
set to the required operation mode. Be mindful of covering the light sensor when testing night conditions.
To set this, refer to the programming section in the manual.
Methods 1 and 2:
1. With the observer in position, switch on the PEL. Both the observer and technician should be in voice
contact.
2. Swing the light around until the observer sees the light. It is not important which colour he sees. The
observer should report the colour.
3. The PEL can now be loosely tightened down to its xings.
4. Depending on colour seen, the technician can determine whether the light has to be moved to the
right or left.
a. Method 1: by instruction from the tower the observer can be asked to walk to the left or right to
determine how much the light is off the mark and inform the tower.
b. Method 2: by instruction from the tower the boat can be asked to be moved to the left or right to
determine how much the light is off the mark and inform the tower.
5. Using electrical tape and a pen mark the original position on the ange of the light.
6. The light can now be loosened and adjusted.
7. By repeating the adjustments in small increments, the light can gradually be moved until the observer
on the mark can move in and out of the colour boundary selected by moving his head to the left and
right by approximately 300 mm.
8. When the technician and acceptance ofcer are satised, the light may be tightened into position.

Method 3:
NOTE: During the alignment process using Method 3, port trafc should be held from passage.
1. The helmsman of the boat MUST accept all instructions from the Theodolite operator. The Observer
MUST stay in a single xed position on the vessel in clear view of the tower. It is suggested to assist
in his recognition that he stand alone or wear a High-VIS vest of a different colour than all other staff
to remain clearly visible.
2. The vessel will position himself at either 1/2 to 1 mile range from the tower on the approximate
bearing line and await instructions.
3. The Theodolite operator will use the telescope to nd the observer
4. With the light switched on the Theodolite operator will instruct the vessel to make a slow passage
perpendicular to the bearing line.
5. The observer will call on the radio e.g.: “Nothing, nothing, nothing, red” and then remove his nger
from the transmission button. At this point the vessel stands awaiting further instructions.
6. The Theodolite operator can then work out the approximate position of the light and instruct the
technician to move the light accordingly in a given direction.
7. It is recommended that if this position is very near the nal position that no adjustment be made on
the rst passage. Instead, the vessel should be instructed to come about and proceed on a reciprocal
bearing to last followed and repeat the procedure. (It should be noted that during this time the vessel
may have drifted and the observer may call “red, red, red” for a long period until he calls nothing.
This is to be expected but should he call a colour change at the same point and the light can then be
moved accordingly.)
8. After a number of passes the team will achieve alignment. NOTE: The speed of the vessel will need to
be tuned to tide movements and in the nal stages this should be a nearly stopped passage.
9. Prior to nal tightening of the PEL the process should be repeated for another boundary check.
10. When the technician and acceptance ofcer are satised, the light may be fully tightened into position.
Horizontal Alignment:
During the alignment it may be necessary to
angle the beam of the light towards the observer
especially if conducted in a small boat. This
should be performed by adjusting the adjustment
screw beneath the barrel and locked as pictured.
A small spirit level placed on the barrel will assist.

FINAL SEA CHECK:
It may be necessary to make a night passage to determine if the automatic night dimming level selected
suits the port and its particular night-time background light.
This is particularly important while making the approaches to the sector light as the port’s ood light or
any nearby lighting drown the mark as they pass behind the sector light. The Harbour Master or Pilots
representative must realise that the light is adjustable and setting a high intensity to assist in long range
identication may perhaps destroy night vision at close range. It is therefore a compromise as the
operators become accustomed to this aid that intensities are not xed in stone and adjustable.
Pilots and Masters will use their own personal marks during both day and night passages to verify the
accuracy of the new aid before they become comfortable with the new addition. In order to make the
most of the PEL, it is necessary to stand in a single position on the bridge without moving from Port to
Starboard. If it is necessary for observations to be made from another point, it is important to remember
only to observe the light from a given point to get a consistent indication of position.
SYNCHRONISATION WITH OTHER AIDS:
It may be part of the scheme to synchronise the PEL with other aids.
If an identication light on the same structure is employed it may be switched on after alignment. The
distance of vertical separation should be selected depending on its purpose.
If the identication light has a sector complimenting and extending the PEL boundaries, this should be
positioned on the centre line within 500mm vertically below the PEL.
If it is an omnidirectional light of a different colour intended to be seen separately from the sector, it
should be positioned (ideally) on the centre line, or at least between 3 and 6 metres below the sector
depending on range.

Care & handling of the PEL
Special care should be taken when handling the Port Entry light. Optics can be easily damaged from
poor handling and incorrect cleaning methods. Be sure to consider the following guidelines:
- The PEL has been supplied in suit packing. Upon arrival of the PEL, inspect for any damage and
immediately notify the carrier. Goods should bot be signed for without unpacking and checking for
damage
- Retain Sealite packing for safe transportation of the PEL to the tower.
- Never place hard or rough surfaces on PEL optics as the lens can be easily scratched and chipped.
- Optics should never be handled with bare ngers as oils from the skin may remove and damage
coated and uncoated surfaces.
- Use only lint-free cloths or lens tissue when cleaning surface of the PEL lens.
- Apply isopropyl alcohol (IPA) directly to your cloth – NEVER directly to the lens. Use slow, even,
light pressure working from edge to edge across the PEL Lens allowing IPA to evaporate.
- If storing the PEL ensure the optics and connectors are protected.
