3 General statements about PAPI System Installation

The first step of PAPI System installation is the calculation required to accurately locate thepositionning of the units relative to the runway threshold and the runway edge. The distance from thethreshold will be determine by the largest aircraft to use the runway, the height of the aircraft wheelsover the threshold, possible obstacles in approach zone, accordance with ILS System…For more details concerning this calculation please se the Paragraph 8.4 of the Part 4 of ICAOAerodrome Design Manual

Once the above distance has been calculated the PAPI position are given as follows :

Fig 1 : LOCATION OF PAPI RELATIVE TO RUNWAY EDGE

The PU3L is mounted on three legs, each comprising a tripod stand, frangible coupling and analuminium tube, the length of which has to be determined at the time of installation. The final length of the tubes will depend upon the individual heights of the PAPI units, these heights being dependentupon local ground conditions etc.. On the centre of each PAPI body is a datum point which can beused to ensure that all of the units are the same level. Please note that the PAPI units should be

mounted as low as possible.

The tube supplied are 60 mm diameter and 400 mm long. Please note that92 mm of tube is placedinside the frangible coupling and this must be allowed for in calculating the required length.






4 Tools and accessories required

4.1 Standard Tools

• Two open end wrench of 22 mm.

• One 22 mm box spanner / socket.

• Two open end wrench of 17 mm.

• One 8 mm box spanner / socket.

• One small flat screwdriver

• One brush or cloth

• One spirit level

4.2 Special Tools

• One set of adjustment tools (supplied in a little case).

Note : Standard surveyors equipment shall be also required to determine the location of the foundation blocks etc..

• One multimeter (for Tilt Switch Installation).






5 Installation

5.1 Civil Works

5.1.1 PU3L unit possible height

In order to help you to fix the topographic heights of the top of the concrete plinth dedicated tosupport the four PU3L Unit of the PAPI. Please take into account the following data (See Fig 2) :

1) The Threaded Rods of the three Legs permit an maximum vertical adjustmentof 55 mm.

2) The Maximum possible distance between the top of Concrete Block andthe Bottom of the PU3L Box is 570 mm (on the Front Legs).

3) The Minimum possible distance between the top of Concrete Block and

the Bottom of the PU3L Box is 300 mm (on the Rear Legs).

Fig 2 : MAXIMUM AND MINIMUM HEIGHT OF PU3L






5.1.2 Concrete plinth standard dimensions

Once the location of the foundations for the PAPI units have been determined, each of the units willneed to have a concrete plinth constructed as per the dimensions given in Fig.3.

Note : These dimensions are minimum requirements suitable for compacted and stabilisedground and may need to be increased due to local conditions. Ideally, the concrete plinths shouldbe level with the ground, however, the requirements for chamfered edges should be bourn inmind.

Three sets of three sealing rods with M10 threads (one per tripod base) may be fixed into theconcrete whilst wet, alternatively, the use of rawl bolts is recommended.

We would also recommend that a conduit elbow tube be placed in the concrete plinth for thesecondary AGL cables.






Fig 3 : STANDARD SIZES OF THE CONCRETE PLINTH






5.1.3 Electrical circui ts

Manholes and conduits dedicated to receive respectively Isolating Transformers and Power supplyCables (Primary and Secondary) must also be supplied and installed into the ground to shelter theequipment used to power supplied the PAPI System.

Manholes and conduits characteristics are function of local needs (type of soil, type of climate, etc…).Nevertheless we can give as an example the great following statements (See Fig 4 and Fig 5) : Useone Manhole (A) for 2 PU3L Units (=>2 Manholes for one PAPI System), Minimise the length of theconduit (B) dedicated to lead the secondary cables (= minimise the distance between the Manhole(A) and the concrete block (C) which support the PU3L Unit), Use one conduits (D) network for eachindependent Primary circuits used for Power supplied the PAPI System (the use of only one or twoindependent circuits is possible).

The final stage of the installation process is to set the elevation angles of the Units.

Note : The angle of approach on the typical airf ield is normally 3 degrees,however , this has to be verified with the client and the local Aviation Authori ty. The standard angular displacement between each uni t is 20

minutes of arc.For a 3 degree approach this would give the unit closest to the runway asetting of 3°30’, the next 3°10’, the next 2°50’ and the last one 2°30’.

5.5.1 Use of the clinometer

Degreeson this line

Minutes onthis line

The 0 of the line of the spirit level is in regard of the first division after the 3°. As one division on thebody line is 15 minutes, the clinometer is adjusted to 3° and 15minutes. If you want to adjust to 3°and 20 minutes, you have to add 5 minute. The line for the minute is fixed on the spirit level, so youneed to adjust the division n°5 in regards with the next division on the body line Then you get 3°+15

‘+5’=3° 20‘. Secure the position by the brake under the spirit level.

and then could be put in service and use.






6 Installations of opt ional devices

As all the PU3L Units are delivered without lamps and any optional devices (Tilt Switch and HeatingResistors), you must install yourself the corresponding devices in the PU3L unit if you want toimplement the corresponding optional function.

6.1 Installation of the tilt switch

The Tilt Switch system is composed of four Tilt Switch devices (One “Master Tilt Switch” Unit andthree “Slave Tilt Switch” Units mounted in the corresponding PU3L (one became the Master and thethree other became Slaves) linked together by Cables. The installation of aTilt Switch System can bemade in three main operations :

1) Mechanical Mount ing and Adjustment of the Devices

in the PU3L Units

2) Wiring of the System

3) Commissioning of the Whole System.

6.1.3 Commissioning of the tilt switch system

After Mounting and Adjustment of the all Tilt Switch Devices in the PU3L Unit and after wiring of the

whole System, you have to Commission the Tilt Switch System. During this commissioning you haveto test either the “Normal Status” or the “Default Status”.

6.1.3.1 Test in normal status

1) Power On the PAPI System (Supply the Corresponding AFL loop(s) with in Current with TRMSValue From 2.8 to 6.6 Amps.2) Control that all the PU3L Units of the PAPI System is light on and operational.3) Remove the Cover of the PU3L Master Unit, and Control the Following things.

A) Control the status of the three LEDs of the Tilt Switch Device (See Drawing here after).* The Red LED (1) showing that the Power Supply Module supply 12 Vdc

is light on.* The Green LED (2) Showing that the Mercury Contacts Loop is Closedis Light on.

* The Red LED (3) Showing that the Mercury Contacts Loop is open is Light off .4) With an Ohmmeter, verify that the Dry Contact of the ”Alarm” Feed Back information is open(meaning PAPI System in Serviceable). Make the measurement between the connections 3 and 4 of the Master Tilt Switch Device Main Terminal.






6.1.3.2 Test in normal status

1) Now Push Down the Plate Supporting the Mercury Contacts In ( A)(see Drawing here after).

2) Wait 5 seconds.3) Verify that all the PU3L Unit Light off. 4) Control the Following things.

A) Control the status of the three LEDs of the Tilt Switch Device.* The Red LED (1) showing that the Power Supply Module supply 12 Vdc

is light on.* The Green LED (2) Showing that the Mercury Contacts Loop is Closed

is Light off .* The Red LED (3) Showing that the Mercury Contacts Loop is open is Light on.

5) With an Ohmmeter, verify that the Dry Contact of the ”Alarm” Feed Back information is Close(meaning PAPI System is “Out Off Service” on miss-alignment). Make the measurement betweenthe connections 3 and 4 of the Master Tilt Switch Device Main Terminal.6) Stop to push Down the Plate Supporting the Mercury Level. 7) Wait 5 seconds.8) Control that now all the PU3L Units of the PAPI System is light on and operational.






9) Repeat Three time the test (from 1) to 7)) creating the default separately on the three “Salve”PU3L Unit

A) Remove the cover and create the Default describe in 1) on the corresponding Slave PU3LUnit.B) Control the status of the three LEDs of the Master PU3L like in 4) A).C) Put Back in place the Cover of the corresponding PU3L Unit.D) Test the next Slave PU3L Unit.

When Default Status have been tested on the four PU3L Units with successyour Tilt Switch System is consider as operational.

6.1.3.3 Problem occurred during commission

6.1.3.3.1 The PAPI system is light off when it is power on

1) Verify the PAPI AFL Loop(s) are Powered On with a TRMS value of at least 2.8 Amps.

2) Remove the covers of all the PU3L

3) Control the status of the three LEDs of the Master Tilt Switch Device.

A) The Red LED (1) showing that the Power Supply Module supply 12 Vdcmust be light “On”.

* LED light Off means that the Control and Supply Module doesn’t supply the 12 Vdc to allthe relays and by default all the lamps are short Circuited.

- Verify that the Master Tilt Switch Module is Supplied (2.8 to 6.6 amps). If it is the casechange the Master Tilt Switch Module and restart the commissioning.

B) The Green LED (2) Showing that the Mercury Contacts Loop is Closed must be Light “On”.* LED light Off means that the Mercury Contacts Loop is Open somewhere. Find where the

loop is open, correct the problem and restart the commissioning.- To find where the Loop is open do as follow :

a) Power Off the PAPI System.b) Open the loop on the PU3L Master Unit. Disconnect the wire Connected to the

connections 13 and 14 of the Master Tilt Switch Device Main Terminal.






c) With an Ohmmeter tested the Mercury Contacts Loop. Verify that the loop is closed(Make Measurement on the wires disconnected in c).

. If the loop is Closed the Problem came from the Master Tilt Switch Device. Test

again that the “Master” Mercury Contacts are Closed.If it is not the case Adjust it again and restart the commissioning .Otherwise Change the Master Tilt Switch Device.

d) If the loop is Open, find where the loop is Open. To do this operate as follow :1) Go to the First Slave PU3L and measure the Mercury Contacts Loop on the TiltSwitch Device Main Terminal. Make measurement between the connections 2 and3 of the Main Terminal.

If the loop is closed. The problem is located on the Wiring between ActualPU3L and the Previous one (here between the Master and the First Slave).Find and Correct it, then restart the * commissioning.If the loop is Open. Test the Mercury Contacts of the Actual PU3L (here theFirst Slave PU3L). Make measurement between the connections 3 and 13 of the Main Terminal. If the Mercury Contacts are Open the problem is located on

Mercury Contacts Plate. Find and Correct it ( make again the adjustment), thenrestart the * commissioning.

2) If the Problem is not located on the First Slave do the same operations than in1) on the Second Slave PU3L.3) If the Problem is not located on the second Slave do the same operations thanin1) on the Last Slave PU3L.

* Before restarting the commissioning don’t forget to reconnect the correspondingwires on the connections 2 and 3 of the Main Terminal of the Master Tilt SwitchDevice and put back in place the covers of the four PU3L.

6.1.3.3.2 Some PU3L of the PAPI system remain light of f

1) Remove the covers of all the PU3L.

2) With a Voltmeter Verify the distribution on the System of the 12 Vdc dedicated to open the “ShortCircuit Relay”.

A) On the first “Light Off” Slaves PU3L (starting from the Master)* Verify the Input 12 Vdc. Make measurement between the connections 1 and 2 of the TiltSwitch Device Main Terminal.

- If the 12 Vdc is not present. The problem is located on the Wiring between ActualPU3L and the Previous one. Find and Correct it, then restart the commissioning.

* Otherwise verify the output 12 Vdc. Make measurement between the connections 11 and12 of the Tilt Switch Device Main Terminal.

- If the 12 Vdc is not present. The problem is located inside the PU3L. Find and Correct

it, then restart the commissioning.3) Put Back in place the Covers on all the PU3L.






6.2 Installation of heating resistor For use in cold or wet areas the PU3L unit could be equipped as an option with one special HeatingResistor. This Heating Resistor must be supplied in 230 Vac (this option need a dedicated supplywiring). The installation of Heating Resistors on a PAPI System is made in two main operations :

1) Mechanical Mounting in the PU3L Units

2) Wiring

6.2.1 Mounting of heating resistors and terminal plates

The first operation to do is to mount one Heating Resistor and one Terminal Plate in the four PU3L of the PAPI System.

6.2.1.1 Mounting of heating resistors

MOUNTING OF

HEATING RESISTOR


A) Remove the Cover of the PU3L (seeParagraph 5.3.).

B) Using the Two set of fixing screw (D)and nut (E), fix the Heating Resistor (B)and its two Radiators (C) on theSeparating Screen ( A) of the PU3L.

C) If necessary put back in place the PU3L

cover.






6.2.1.2 Mounting the terminal plates

The connections of the Heating Resistors with external wiring are done using Terminals Mounted onPlates that you have also to mount in the PU3L Units.

Note : If your PU3L is also equipped with the Optional Tilt switch System. The connection of theHeating Resistors are done on the Main Terminal of the Tilt Switch Devices. In this case seeprevious chapter for the mechanical installation of the Tilt Switch Devices.

If your PU3L is not equipped with the Optional Tilt switch System. You have to install special TerminalPlates in all the PU3L.

MOUNTING OF

TERMINAL PLATES


A) Remove, if necessary, the Cover of thePU3L (see Paragraph 5.3.).

B) Using the Two Fixing Holes (D) locatedon the PU3L Base Plate ( A) and the twoFixing Screw (C) located on the TerminalPlate (B), fix and lock the Terminal Plateon the PU3L Base Plate.






6.2.2 Cabling of the heating resistors

The second operation to do is to make the electrical cabling over the PAPI system This cablingoperations are divided in two separate steps : Cabling internal to PU3L Units and Cabling External toPU3L Units.

6.2.2.1 PU3L internal cabling

This operation permit to connect the two poles of the heating Resistor to the Main Terminal of the Terminal Plate or of the Tilt Switch Device.

PU3L INTERNAL CABLING


A) If necessary Remove the Cover of thePU3L (see Paragraph 5.3.).

B) Pass the Resistor two Wires under theReflector Holder ( A), under the TerminalPlate (or Tilt Switch Device) (B). Thenconnect them to the Connections 15 and16 of the main Terminal.

C) If necessary put Back in place the PU3LCover.






6.2.2.2 PU3L external cabling

6.2.2.2.1 Passing a Cable Through a Compression Packer

Concerning connection of cables coming from out of the PU3L Units the first step is always to passthe corresponding cables through the Compression Packers.

FOR EACH CABLE TO CONNECT


B) Remove the Plug (D) from the LowerNut (C) of the Compression Packer (A).Note : all the unused cable entries musthave the blanking plug left in situ inorder to maintain IP rating of the unit.

C) Pass the Cable (F) - Through the Compression PackerLower Nuts (C),- Then through the CompressionPacker Gasket (E),- And through the Compression PackerBody (B).

D) Pull the Cable about 20 cm into the box


F) Bare the cables two cores for a distanceof about 10 mm.

G) Connect the cable two cores to the Terminal Plate dedicated terminal (seenext Paragraph).


I) Reassemble the Compression PackerBody (B) and tighten to suit.
