Operating Considerations

Power supply

Use the device with a suitable power supply.

Electrostatic Discharge (ESD)

Handle with care and avoid damage of electrical components by electrostatic discharge (ESD) especially when working without housing:

Discharge body static (contact a grounded surface and maintain contact).
Avoid all plastic, vinyl, and styrofoam (except anti-static versions) around printed circuit boards.
Do not touch components on the printed circuit board (PCB) with your hands or with conductive devices.

Overheating and Cooling

Attention

"Overheating"

Heat can affect the image quality, damage the device, or shorten the life of the device. Provide adequate dissipation of heat.

→ Balluff recommends the following for proper heat dissipation:

Always take measures to ensure cooling.
Monitor the temperature of the device to activate cooling measures (properties and mechanisms are available: Working with the temperature sensors).
Only operate the device in mounted condition.
- Attach the device to a sufficiently large heat sink.
- Keep the heat transition resistance as low as possible.
In mounted condition, it is also possible - or in addition - to cool the device using a fan.
For board-level devices recommend to use or configure the device with a thermal conduction plate.

For extended temperature (-ET) models:
- The mainboard's temperature may not exceed 65 °C!

Additional temperature and power consumption notes concerning BVS CA-GX0 and BVS CA-GX2

BVS CA-GX0 and BVS CA-GX2 cameras have very different power consumptions depending on sensor technology and connection and operation modes. As a rule of thumb:

CMOS sensor camera with single network interface controller (NIC) output consumes less around 4W
CCD equipped cameras with quad tap use and dual NIC output and max. pixel clock may consume up to 9W
CCD sensor dual tap mode consumes 1.7W less than quad tap
For BVS CA-GX2: Dual NIC mode (so-called link aggregation [LAG] or bonding) consumes 0.8W more than single NIC used

Datasheets of cameras commonly specify the allowed temperature range by indicating the min/max. ambient temperature of the air (e.g in a room) where the camera is installed and operated. Whereas this is good for a first indication and comparison it presents a fuzziness for the temperature of the components inside because it is not defined how the camera is mounted and thus the overtemperature inside the camera is not clear.

And since each installation is different, Balluff cannot supply a strictly required procedure for proper heat dissipation. Instead, we provide the following general guidelines:

In all cases,

you should monitor the temperature of the camera by using the two built-in temperature sensors (separate for sensor board and mainboard) and
make sure that neither the sensor temperature nor the mainboard temperature exceed 75 °C.

Keep in mind that the camera will gradually heat up during the first hour of operation. After one hour, the housing temperature should have stabilized and increases no longer.

If your camera is mounted on a substantial metal holder or component in your system, this may already provide sufficient heat dissipation because this metal component presents a low thermal resistance for the heat path.
You may use additional heat conductors between the camera and the holder to bridge gaps.
The use of a fan to provide air flow over the camera is an extremely efficient method of heat dissipation.

The fan can be driven directly by one of the robust camera outputs and controlled by the camera itself (temp. settings to switch fan on and off with hysteresis) as long as

the switched voltage at the output is suitable for the used fan (12V up to 24V) and that
the fan does not consume more than 700 mA which is the maximum one output of the camera can deliver.

Available CPU Socket 7 (370 or socket A) active cooler fit very well directly on any side of the camera by means of thermal glue. Ask for support if you need further assistance.

Installation

Avoid installing or storing the Balluff/MATRIX VISION device in the following environments:

Environments exposed to direct sunlight, rain or snow.
Environments where combustible or corrosive gas exists.
Excessively warm or cold environment (Operating ambient temperature: 0 to 45 °C)
Humid or dusty environment.
Place subjected to excessive vibration or shock.
Environment exposed to strong electric or magnetic field.
It is recommended to mount the Balluff/MATRIX VISION device on a thermoconducting surface such as aluminum or other metals rather than plastic or wood.
Please contact manufacturer or local distributor if you want to use additional enclosures for higher ingress protection.
Do not aim the Balluff/MATRIX VISION device at the sun or other very strong light sources, otherwise you can destroy the image sensor.

"CCD phenomenon: Smearing": Vertical smearing may appear, in the image. However, this is not due to failure of the Balluff/MATRIX VISION device.

Confirm the power is off before connecting or disconnecting a signal cable. Grap connectors by the body, not the attached wires.

Adjusting the C-mount type 1 with adjustable backfocus

The C-mount type 1 lensholder allows a precise adjustment of the backfocus of the C-mount by means of a backfocus ring which is threaded into the C-mount and is secured by a lock nut ring which itself is secured by two screws. The mechanical adjustment of the imaging device is important in order to achieve a perfect alignment with the focal point of the lens. This adjustment is made before leaving the factory to conform to the standard of 17.526 mm (in air) and should normally not require adjustment in the field. However, if the backfocal plane of your lens does not conform to the C-mount backfocus specification or if you have e.g. removed the IR-CUT filter, renewed adjustment may be required.

Figure 1: Lensholder C-mount type 1 with ring (1) and lock nut ring (2)

How to proceed:

Loosen screws (location as shown above by arrows) of the lock nut ring with an Allen key (0.9 x 50).
Loosen the lock nut ring.
With the lens set to infinity or a known focus distance, set the device to view an object located at "infinity" or the known distance.
Rotate the C-mount ring and lens forward or backwards on its thread until the object is in sharp focus.
Note
Be careful that the lens remains seated in the C-mount.
Once focus is achieved, tighten the lock nut ring, then tighten the two locking screws of the lock ring without applying excessive torque.

Adjusting the C-mount type 2 with factory-set backfocus

The C-mount type 2 lensholder does not support backfocus adjustment. However, with the four screw locks at the front of the lens holder, it is possible to rotate the C-mount ring.

Note: In combination with BVS CA-SF2-0089Z and BVS CA-SF2-0124Z the C-mount lens holder has to look upwards during the adjusting. Otherwise the aperture can jump out of the guide.

Loosen the screw locks with an Allen key (2.5 mm).
With it, you can adjust the position of the lens, for example, to have the scale or the locking screws of the lens at a specific position.

Figure 2: Lensholder C-mount type 2 with ring (1) and screw locks (2)

Note: Always tighten the screws in a diagonal sequence first slightly and then little by little to a torque of 0.9 Nm.
