Balluff - BVS CA-GT Technical Documentation
Important Information

General Notes

  • We cannot and do not take any responsibility for the damage caused to you or to any other equipment connected to the Balluff/MATRIX VISION device. Similarly, warranty will be void, if a damage is caused by not following the manual.
  • Handle your Balluff/MATRIX VISION device with care. Do not misuse it. Avoid shaking, striking, etc. The Balluff/MATRIX VISION device could be damaged by faulty handling or shortage.
  • Do not modify the Balluff/MATRIX VISION device or use it with external covers removed. These may cause failure, void any warranties and pose a safety hazard.
  • Do not attempt to disassemble Balluff/MATRIX VISION device.
  • Do not use accessories not recommended by Balluff/MATRIX VISION as they may cause hazards.
  • The Balluff/MATRIX VISION device should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including amplifiers) that produce heat.
  • When installing or removing a lens, take care that water or dust does not enter the inside of the Balluff/MATRIX VISION device.

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.
  • In case of inadequate cooling, the device switches to a OverTemperature to avoid hardware damages.

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.
  • 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.

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

Operation

  • Observe that flammable objects, water or metal do not enter the Balluff/MATRIX VISION device interior. These may lead to failure or accident.
  • Stop using the Balluff/MATRIX VISION device at the approach of electrical storm (thunder audible). Protect the Balluff/MATRIX VISION device from rain if using it outdoors.
  • In the event of abnormal functioning, switch off the Balluff/MATRIX VISION device and disconnect the power cord. Contact Balluff (suppo.nosp@m.rt.d.nosp@m.e@bal.nosp@m.luff.nosp@m..de).

Cleaning

  • Use a blower or a lens brush to remove dust on the lens or the optical filter.
  • Do not disassemble front flange.
  • Clean case with dry soft cloth. Use neutral detergent liquid if needed; wipe the cover with dry cloth.
  • Do not use benzene, thinner, alcohol, liquid cleaner or spray-type cleaner.
