    TO44/6.2-150-V-B Commissioning 6.3.2 Adjusting the aperture The lens features a variable aperture. ADVICE Change in light intensity The light intensity is halved in each case at the transitions 6 / 8 / 11 / 16 / 22 as well as at 10 / 14.

  • Page 54: Operation

    TO44/6.2-150-V-B Operation 7 OPERATION ADVICE The front lens can be protected from foreign bodies by using the UV filter (protective glass). see "Filter für Filtergewinde objektseitig" Keep the lens away from foreign objects (dusts, mist, water splashes or similar) during operation. These substances can damage the optical surfaces.

  • Page 55: Maintenance And Service

    TO44/6.2-150-V-B Maintenance and Service 8 MAINTENANCE AND SERVICE 8.1 Maintenance The device is maintenance-free. Depending on the operating environment, it may have to be cleaned. Perform cleaning only if the imaging characteristics are noticeably disrupted. Only clean surfaces accessible from the outside. Do not open the lens.
  • Page 56 TO44/6.2-150-V-B Maintenance and Service Cleaning the optical surfaces NOTICE Follow the specified cleaning sequence. Never use dry cloths for cleaning. This allows dust and other contaminants to be rubbed into the lens surface, thereby damaging it. 1. Remove non-adherent dusts with a blower brush or cleaned compressed air.
