2.1 Power Supply
PxVision needs 24 VDC for power supply:
The Max current is 0,105 A, this is considered for full load with all ILUMINATION LED ON
2.2 Ethernet Port
The PxVision system uses a ETHENET RJ45 port for PC connection
It is recommended Ethernet cable cat. 5e with shield
2.3 PC Connection
The PC connection is by Ethernet port
The PC IP address must be on same category of PxVision system, therefore if PxVision has an IP address of 10.0.0.82
the PC must have a STATIC IP (eg.) of 10.0.0.80.
For setting the IP address of PxVision use the PxVisionBrowser application.
For setting a new IP address is necessary to know the current IP address, if it is unknow, see the procedure se
PARAMETERS RESET.
If the IP is known run PxVisionBrowser and execute the following step:
1) Press

Insert the new IP address and press SAVE.
Is necessary to restart PxVisionBrowser for update the new IP address
2.4 Parameters Reset
If the IP address of PxVision is unknown is possible to RESET the parameters to default:
1) Turn on PxVision without PC connection
2) With a pointed object “like to paper clip” press and hold the RESET button for 3-4 Sec.
3) During this operation the LED YELLOW L1 is blinking
4) Release the button RESET
5) Now the new IP address is set to 10.0.0.82
2.5 Status Led
The 3 LED show the following status:
L1 Yellow Led Blink when the PC download the images from PxVision (used also for RESET procedure)
L2 Green Led Blink when PxVsion is ready. If OFF the system has problems
L3 Red Led Power On
2.6 Illumination Led
The PxVision has 8 LED withe light for objects illumination.
Can be ON a single LED with variable Power from 0 to 100%.
For management LED use PxVisionBrowser.
WARNING
SELECT ALWAYS DLL PxPlusCamera.dll AFTER SAVE

2.6.1 Illumination LED limitation
In some situation the illumination could generate “areas of reflection light” that can create a noise in the
acquisition image
See the following images.
2.7 S.O.
As we can see the image a) is acquired with LED off and the image b) with LED On.
In the image b) there are an areas of reflection light generated by LED ILLUMINATION in the camera lens.
The acquisition image could be wrong.
In this situation the best solution is use an external light without reflection or natural illumination
a) Image with LED Off
b) image with LED On

CREATE AREAS OF SHADOWS ON THE OBJECT ACQUIRED
WARNING
THE X-Y AXIS OF CAMERA MUST BE THE SAME OF THE
SYSTEM, OTHERWISE CHANGE THE MOUNTING SIDE

2.9 Focus Lens
PxVision can mounting two lens types:
Autofocus or Fixed Focus.
2.9.1 Autofocus
These lenses are motorized and can used in AUTOFOCUS MODE, therefore the camera make an automatic
procedure of focus on the object acquired, or in DIGITAL MANUAL FOCUS by PxVisionBrowser.
Enable the Autofocus mode
Or Disable the Autofocus mode and use the Slider for Manual Digital Focus
Difference from Autofocus and Manual Focus
When the camera is in Autofocus Mode, the object is focused automatically by camera, this generate a delay time
before the image will be available (more or less 1 sec) and in some case the interested object could not be focused.
Use Manual Focus for eliminate this problem.
However the Autofocus Mode is necessary when PxVision is mounted on “Mobile Axis”that can frame objects
from different distances.

10
PXVISION
2.9.2 Fixed Focus
These lenses have a fixed focus and not are motorized, therefore the focus must be set in manual mode based a
focal length of lens and object distance.
Manul Focus Procedure
By PxVisionBrowser enable START TEST with MultiFrame checked from menù Camera Setting
The system start to acquire images in continuous mode.
1) Remove the screw from lens.
2) Rotate the lens in CW or CCW direction up to the image is focused.
3) Insert the screw in the lens and block it with a light pressure.
WARNING
IF THE LENS IS TO END OF SCREW THREAD OR OUT OF IT, MUST
OUTDISTANCE THE CAMERA, FROM THE OBJECT

2.10 Lens Cleaning
For a corrects images acquisition the lens must be clean.
A periodic and correct cleaning of lens must be made.
Use only specific products not abrasive like used for glasses (soft cloth and Spray or Liquid product)
2.11 Difference between Lenses with various focal length
The focal length allows to frame portions of objects from different distances.
Greater focal length is high, more is the lenses ZOOM.
Short focal length can generate the Fish Eye effect on image partial recoverable from function of PxVisionBrowser.
2.12 Resolution Camera and Definition Image
Exists a specific relationship between camera resolution and image definition.
Eg: in a FOV (Field Of View) of 50 mm on long axis and 37.5 mm on short axis, the object definition for a Camera
1600x1200 pixel (4:3) will be di 0.031 mm per pixel.
This definition can be changed with a greater camera resolution or a reduction of FOV.
WARNING
NEVER REMOVE THE LENS FROM THE CAMERA DURING THE CLEANING THIS
OPERATION COULD DAMAGE THE CCD SENSOR

3Notes on the CE legislation
We have two directives about electronic devices, regarding the Px Vision: the 2006/42/CE (machine directive) about safety use of
the devices and 2004/108/CE about electromagnetic compatibility.
About the first (machine directive), electric/electronic devices must complies the Union harmonisation legislation (Low Voltage
Directive), Directive 2006/95/EC (until April 19th, 2016) and Directive 2014/35/EU (from April 20th, 2016) but it can be applied on
devices supplied at 50-1000Vac or 75-1500Vdc. Px Vision works at a voltage of 24Vdc (thus Intrinsically “safe”), so it belongs to
"very low voltage" devices (class 0 legislation CEI 11.1), on which it isn't no legislation about.
On electromagnetic compatibility, regarding the Union harmonisation legislation Directive 2004/108/CE (until April 20th, 2016)
and Directive 2014/30/EU (from April 20th, 2016), the device can be considered inherently benign in terms of
electromagnetic compatibility because its inherent physical characteristics are such that:
a) it is incapable of generating or contributing to electromagnetic emissions which exceed a level allowing
radio and
telecommunications equipment and other equipment to operate as intended;
b) it will operate without unacceptable degradation in the presence of the electromagnetic disturbance
normally present in its intended environment
Moreover, this device cannot be classified as a "finished appliance with an independent functionality", due the
Px Vision haven’t any use outside a complex electromechanics system, the machine electric board, made by a manufacturer in
an industrial ambit and not by a final user.
Thus, it hasn’t any certification duty.
PROMAX however, can institute some specific measure as a pre-compliance, in case of particular demands of costumers, regarding
the device electromagnetic characterization.
For example, can be made some measure under the CEI EN 61000-6-1 norm (2007 generic norms – residential, commercial and
light industrial ambient immunity) or CEI EN 61000-6-1 (2007 generic norms - residential, commercial and light industrial ambient
emission)
