DESCRIPTION
The PH 2066UK is designed to VOSA 2005 specification to facilitate the rapid accurate testing
and adjustment of car and commercial vehicle headlamps in accordance with VOSA MOT test
requirements.
The optical box is mounted on a single vertical column and it is easily adjusted for height and it will
remain in the position selected. The column is rigidly connected to a four wheeled trolley which moves on
two rails fastened to the floor. The wheels of the trolley are machined in a wide 'V' section, to run on a
similar section rail. The 'V' section reduces the likelihood of the trolley assembly rocking and therefore
increases the stability and the accuracy of measurement.
The optical box consists of a condensing lens and aiming screen which can be viewed through the
observation panel in the top of the unit. A light cell fitted to ensure that the 'hot spot' can be accurately
determined. Provision is made for the instrument to traverse each side of center, to permit alignment with
the longitudinal axis of the vehicle.
To calibrate the PH 2066UK in accordance with the requirements of VOSA requirements, it is necessary
to use Calibration kit WTLASER. This consists of a Class 2 laser device mounted on a stand. The calibration
of the PH 2066UK should only be completed by an authorized competent person.

PREPARING THE HEADLIGHT SETTER
1) Fit the third wheel on the base (Screw 8X60)
2) Mount the handle of the optical chamber. (Screws 5X25)
3) Mount the laser on the column. Be careful the cup springs
must have the concave part side by side.
4) Mount the column on the base
5) Fit the fixing screw under the column with the appropriate washer.
6) Install the optical camera with the three screws indicated by the
arrows without tightening them definitively.
7) Align the column perpendicularly to the floor using the screw located
on the base.
8) Adjust the optical camera until it is aligned with the measurement

surface. Use the three screws to secure it.
If necessary adjust the internal level, bringing the bubble to the exact centre.
9) Adjust the laser line using the screws indicated so that the
line drawn is parallel to the edges of the optical chamber,
both front and rear.

INSTALLATION
Site
The floor area designated for headlamp testing requires careful selection and preparation. For MOT requirements the
vehicle standing area and the equipment area where the rails are to be fitted must be level as follows:
Rails +/-2mm
Standing Area +/-6mm over 3 meters.
For non MOT requirements the vehicle standing area does not need to be precisely level as a slight continuous
gradient, maximum 0.4% will not affect accuracy.
NOTE: Preparation of the site to these standards is the customer's responsibility.
Installing Rails
Two sets of rails, each secured to the floor by screws and plastic raw plugs. The rails are positioned at right angles
to the vehicle's longitudinal axis. The two rails must be leveled with each other, shimmed as necessary, and re-
checked after tightening down. In the final position the rails must be level within +/-2 mm.
Where the vehicle tested, or any other traffic, will pass over the rails, each rail must be recessed into the floor and
fully supported along its entire length by grouting as necessary, see Fig. 2. It is helpful if lines are painted on the
floor at 90 degrees to the Tester's rails to enable the accurate positioning of vehicles for testing.
Leveling the trolley
The two rear wheels are equipped with an integral cams which are factory set and normally do not require
adjustment. The level can be checked placing a spirit level on the trolley base together with the use of a plumb line
attached to the column. Should any adjustment be required the cams can be adjusted as follows (See Fig. 3):
Loosen screw 1 and just slacken screw 2.
Raise or lower the wheel as necessary.
• Fully tighten both screws.
Re-check level of trolley base using a spirit level.
Re-check that the column is vertical, using a plumb line.

Column
• Insert the column into the appropriate hole of the base .
• Check column locks correctly when the pedal is operated.
• Retain column in position with the lower screw.
Alignment Laser
• Ensure that it rotates smoothly and that the leading edge of the optical box aligns correctly with the line
of the laser.

METHOD OF INSPECTION
Positioning the vehicle (See Fig. 7)
To check headlamp aim:
1 Refer to the Tester's Manual for guidance on test procedures, types of headlights and
pass/fail criteria.
2 Position the vehicle as accurately as possible at 900 to the tester rails. The headlamp
lens should be positioned 350mm (+/- 150mm) from the lens of the beam tester. Ensure
that the headlight lens is clean.
3 Measure the height to the centre of the headlight lens from the floor and adjust the
height of the optical box to the same height. If the rails are recessed then this must be
added to ensure the optical box is at the correct height. There is a tolerance of +/- 10mm.
(NOTE 1) The above information is based on the criteria published in the MOT Inspection Manual which is an HMSO
publication and is available from most bookshops. Always refer to the current edition for any amendments or changes
to current legislation.

Checking the optical box alignment.
It is very important to align the optical box with the longitudinal axis of the vehicle. This
is to ensure that the aim of the headlight to the left or to the right is correct. To verify and
adjust the position of the optical box is as follows:
•Position the laser so that it is facing downwards towards the optical box.
• Identify two symmetrical points as close to the sides of the vehicle as possible. See
Fig.8
• Check that the line of the laser accurately bisects both points. See Fig. 9

pag. 17

pag. 18
Adjusting the alignment of the optical box.
If the line of the laser does not accurately bisect the two points, then the optical box has to be realigned.
To realign the optical box, release column by pressing the foot pedal and rotate the optical box and column
until the correct alignment is obtained. Lock column by pressing the foot pedal. Re-check that the
alignment is correct..
CHECKING THE HEADLIGHT AIM.
With an assistant sitting on the driving seat switch on the headlamps to the beam on which the headlamp is
to be checked. Note: When checking headlamp aim on vehicles with hydro-pneumatic suspension systems,
it may be necessary to have the engine idling. If this is required, ensure that the handbrake has been applied
and the transmission is in neutral or park before starting the engine. To check headlight aim, proceed as
follows:
• Determine the appropriate headlamp beam image and its aim.
NOTE: Pre C.1950 headlamp beam images may not conform to either diagrams 12, 13 or 14. In such cases
check that dip beam headlamps are aimed so they do not dazzle, i.e. the beam image brightest part is aimed
at least 0.5% below the horizontal or for headlamps which cannot be checked on dip beam, check that the
main beam headlights are aimed so that the beam image centre is on or slightly below the horizontal 0%
Line If the outline of the hot spot is difficult to determine then move the optical head and observe the
readings on the Luxmeter, until the highest reading is obtained.

EUROPEAN TYPE HEADLAMP CHARACTERISTICS (NOTE: 1)
1 An asymmetric dipped beam, pattern with a distinctive horizontal cut-off on the right, and a 15-degree wedge
of light above the horizontal (the “Kick up”) towards the left.
2 A lens with one or more asymmetric stepped patterns moulded in the glass.
3 A lens may carry:
- European approval mark –a circle containing an “E” and a number, or
- Rectangle containing an “e”, and a number
The European approval mark should incorporate a single or double-headed arrow.
The dipped beam is denoted by either:
- Capital letter “C” above a capital “E”
- Capital letter “C” above an “e”
NOTE: Setting “E” Beam Headlamp aim
These dip-beam headlamps should be set to aim downwards the amount shown on a marking which is either
close to the vehicle manufacturer’s plate or the headlamp.
For vehicles without a marking, the downward aim should be set as follows:
- 1,3%, if the headlamp centre is not more than 850 mm. from the ground
- 2.0%, if the headlamp centre is more than 850 mm. from the ground
Reason for rejection
1 The beam image “Kick-up” is to the offside.
2 For headlamps with centers not more than 850 mm. from the ground, the beam image horizontal cut-off
is not between the horizontal 0,5% and 2% lines, i.e. the red tolerance band.
3 For headlamps with centres more than 850 mm. from the ground, the beam image horizontal cut-off is
not between the horizontal 1,25% and 2,75% lines, i.e. the blue tolerance band.
4 The beam image “break point” is:
- To the right of the 0% vertical line or
- To the left of the vertical 2% line

BRITISH AMERICAN TYPE (CHECKED ON MAIN BEAM) - CHARACTERISTICS:
(NOTE: 1)
1. Headlamps tested on main beam have a symmetrical main beam pattern with a central area of maximum
intensity (hot spot)
2. This type of lamp generally has a circular lens which may be marked with a figure 1 followed by an
arrow indicating the direction of dip
Reason for Rejection
1. The 'hot spot' centre is above the horizontal 0% line.
2. The 'hot spot' centre is to the right of the vertical 0% line, or to the left of the vertical 2% line.
3. For headlamps whose centre is not more than 850 mm from the ground, the 'hot spot' centre is
below the horizontal 2% line.
4. For headlamps whose centre is more than 850 mm from the ground, the 'hot spot' centre is below
the horizontal 2.75% line.
