1.7. Sensor Display
An optional dedicated sensor display may
also be attached to indicate the current
position in the sensor range.
1.8. Optical Pens
The optical pen or optical probe is the
measuring head of the sensor. It is
connected to the controller via an optical
fibre. The sheath is generally orange in
colour.
The various optical pens are defined by
different measuring ranges and resolutions.
Each optical pen offers a working distance, a
measurement dynamics, a spot size on the
target as well as an angular opening of the
light beam, making it unique.

Proscan 2200 (Chromatic Sensor) User Manual V.4.0
2.0 Installation Considerations
2.1. Environment
The stand contains both mechanical and electronic components. It should be located in a
sheltered, dry environment with temperatures controlled within 10 to 35 degrees C. Care
should be taken to prevent excessive dust ingress, this may enter electrical and mechanical
components with adverse effects including excessive mechanical wear, clogging of cooling
fins etc.
If the Proscan is moved from a cold to a warm environment, allow at least 30 minutes for the
temperature and dew-point to stabilise, before applying power.
Before taking measurements, it is recommended that the electronics and sensors are
powered and allowed to warm up for approx 30 minutes. This allows the components to
stabilise and provide optimum performance.
2.2. The Stand
The stand contains a precision X/Y table and forms the measuring bed for samples which are
being analysed. Whilst taking measurements this table is in continuous motion, and, as such,
it is important that consideration is given to its location and setup. In addition, the stand also
houses custom communication, control, and data collection ARM PCB (Artemis board), and
power electronic components. Subsequently it should not be placed near areas of extremely
strong magnetic fields
The stand should be mounted on a very robust, vibration free, rigid surface. Do not place on
an anti-vibration table as this likely to oscillate in reaction to the scanning motion. Vibration or
motion of any sort will be translated to the measured surface and will adversely affect
measurements. Purpose built steel and granite metrology tables can be supplied for use with
this equipment, please contact [e-mail] for further details.
On the underside of the stand there are 3 adjustable feet, each fitted with a locknut. These
feet must be set so that the stand sits firmly, and approximately level, with no trace of rocking
or motion. Before attempting adjustment, the locknut should first be backed off using a 17 mm
spanner, adjustment requires a 10 mm spanner. Once complete, retighten the locknut.
Exercise extreme caution when adjusting the stand feet. Use blocks to
prevent the stand accidentally dropping

2.3. The Power Supply Module
The PSU Module contains power supplies and mains / DC power distribution. It needs to be
installed in close proximity to the stand as the interconnecting cables are 3 m long. Generally
the PSU Module is situated alongside the stand. Ensure there is adequate clearance (50 mm)
around the enclosure ventilation holes.

maximum load of 10 Amps, and a max inrush current (at cold power up) of up to 21Amps. It is
not supply voltage switchable. Please see product labelling for information on the voltage
applicable to your Proscan.
The power supply should be clean and free of high voltage transients.
Connecting an incorrectly rated power supply may cause catastrophic
system damage

Proscan 2200 (Chromatic Sensor) User Manual V.4.0
3.3. Connections to the rear of the PSU Module
Before connecting the main power umbilical to the PSU Module, please ensure that the
system is disconnected from the electricity supply.
A basic system PSU Module, will look similar to the following illustration: -
Connect the stainless steel sheathed power cable labelled ‘PSU POWER’ to the ‘POWER
OUT’ socket. The connector is keyed and can only be inserted in one orientation. Once
inserted, rotate the collar clockwise until it locks on the locating pins, being mindful not to
damage any of the pins by forcing the connector.
Connect an IEC power cable to the socket, and after checking that everything is safe, and
that all cables are correctly connected at both ends, the PSU may be switched on using the
rocker switch next to the IEC connector.
3.4. Connections to the rear of the stand
Only connect/disconnect cables with the system PSU Module fully powered down.
First connect the stainless steel sheathed power cable labelled ‘STAND POWER’ to the
‘POWER’ socket, the connector is keyed and can only be inserted in one orientation. Once
inserted, rotate the collar clockwise until it locks on the locating pins, being mindful not to
damage any pins by forcing the connector.
There is no connection to the female 9 way ‘D’ connector labelled ‘ENGINEER ONLY”’.

12
Proscan 2200 (Chromatic Sensor) User Manual V.4.0
3.5. Main Power Connection
Once the cables are all firmly connected and suitably supported, power can be applied to the
system, via the 10 Amp fused IEC connector on the rear panel of the PSU Module. A spare
20mm T 10A fuse is located in the connector fuse carrier, should it be required.
The system is switched on using the POWER
ON rocker switch, immediately next to the
IEC power inlet socket, and alongside the
Serial Number label.
3.6. Switching On
Keep fingers and objects clear of the stand when powering
the system for the first time !!
Once all the cables are in place and all objects are clear of the stand, it is safe to switch the
system on.
On switching on the PSU module, the 5 and 24V LED indicators on the front of the Module
should illuminate.
Correct booting of the Artemis board is indicated by the regular flashing of the ‘BOOTING’
light. This light will start flashing almost immediately upon powering up. Once flashing, the
system is ready to use
Ideally, allow the sensor a few minutes to temperature stabilize.
Keep fingers and objects clear of the stand when entering
software !!

Proscan 2200 (Chromatic Sensor) User Manual V.4.0
4.1.1. Changing ‘S’ Type Sensors
The orange optical fibre for required sensor needs to be plugged into the sensor controller.
This is done using the green quick-change connectors. Push the connector firmly into the
controller until a click is heard.
The optical fibre is delicate, take care when handling and route the fibre away from potential
snag or crush areas.
If there is no sensor plugged into the controller; insert the blanking plug into the sensor input
to prevent dust ingress.
After fitting an ‘S’ type sensor to the Proscan, ensure that the correct sensor is selected on
the ‘S’ type control unit.
Select the correct sensor in the Proscan 2200 software.
Before taking measurements, allow the sensor to :-
•Warm up fully (approx 15 minutes)
•Dark reference the sensor
Ensure unused sensors are stored where they not going to get damaged.
4.1.2. Sensor Mounting
The sensors are fitted onto a mounting plate
which locates onto the front of the Z drive
assembly via a ‘V’ groove and rod
arrangement. They are held in place by a
thumb screw.
Select the sensor you wish to use, and place on the front of the Z drive, towards the right
hand side, locate with the groove/rod arrangement. Tighten the thumbscrew until the sensor
is held firmly in place.
Use of excessive force may lead to damage of the
thumbscrew!!
Thumb screw

16
Proscan 2200 (Chromatic Sensor) User Manual V.4.0
Once the sensor has been changed, replace the nose cone. Select the appropriate sensor via
the Tools/Sensor Selection menu in the Proscan 2200 software.
5.0 Dark Referencing
5.1. Acquiring the dark signal
The dark signal of the sensor is generated by undesirable back-reflections on the optical
surfaces inside the sensor. This signal must be measured and saved to the non-volatile
memory so that it can be subtracted from the measured signal. The level of the dark signal
depends on the sampling rate and on the LED brightness.
A dark signal acquisition is performed during adjustment by the manufacturer, but must be
repeated at regular intervals.
5.2. Recommendation
The dark signal acquisition procedure should preferably be performed at least a quarter of an
hour after switching the sensor on, in order to ensure that sensor has reached thermal
equilibrium.
Dark signal measurement may be launched by pressing the “Dark” button on the sensor front
panel. This operation may take a few dozens of seconds, as the sensor measures and saves
the dark signal at all pre-set frequencies successively.
In order to perform a dark signal acquisition, it is essential to have no object within the
measurement field, or even better, to blank off the light beam by applying a piece of paper
over the tip of the optical
pen.
•Press the “Dark” button on the front
panel of the sensor.
•The “Intensity” and “Measure” Led
indicators
•on the front panel blink on and off in
green alternatively, to indicate that
the operation is in progress.
•Keep the optical pen tip blanked off.
When measurement is done, the 3
LED indicators blink on and off
simultaneously, and their colour
indicates the result of the operation.
Green if the level of the acquired dark signal is satisfactory at all rates
Orange if the dark signal level is too high at low rates, but it is still possible to measure at
higher rates
Red if the dark signal level is too high at all rates.
The piece of paper can now be removed and the sensor can be used in the normal way.

Proscan 2200 (Chromatic Sensor) User Manual V.4.0
6.0 Manual Z Height Control Buttons
On the front of the Proscan Base there are four buttons to manually set the ‘Z’ axis height of
the sensor. This assists the placement of the sample to be scanned and then setting the
initial height of the sensor relative to the sample for optimum scan range. (Generally, 50% of
the sensor range reading).
Setting the Z height control in the Proscan Software (Please refer to the software manual)
enables the button functions.
Fast Move Button Home Button
Down Button Up Button
It is essential that the ‘Z’ Axis is homed (fully up position) before attempting any height
adjustment.
Holding the Fast Move Button simultaneously with the Up / Down button will set a higher
move speed for initial placement. The final position can be ‘fine-tuned’ at the lower speed.
The sensor display is configured to show the percentage of the range, rather than height
reading as the mid-range point would differ for a particular sensor pen.
7.0 Camera
The Proscan 2200 system may have,
optionally, a camera installed to aid correct
placement of test sample .
This is mounted in close proximity and height
as the sensor pen.
(Nose cone cover shown removed)
7.1. Camera Application
The display from the camera is supported by a utility named “ScantronCameraViewer”
As there is a physical offset from the camera’s focal point, there is a facility built into the Key
Move Stage control screen in the “Proscan” application that enables the user to move
between the sensor / camera focus position. Please refer to the software manual.
