5.1 Installation of the projection lens

Warning: Only use TLD+ ZOOM lenses. Using other lenses can touch and damage the mechanics of the build-in Actuator! This can result in loud rattling noises and a damaged Actuator.
How to install
  1. Verify if the projector is switched off or that the projector shutter is activated (shutter is activated when the shutter icon on the projector keypad is red).
  2. If present, remove the dust cover from the lens holder.

    Tip: While not placed in the projector, place the dust cover in a lockable plastic bag to prevent dust from gathering on the cover.

  3. Place the lens holder in the “unlocked” position as follows:. Do this by pulling the lens lock handle (reference 1) outward and then towards the electrical socket (reference 2) as illustrated.

    1. Pull the primary lens lock handle (reference 1) outward and then towards the electrical socket (reference 2).
    2. Pull the secondary lens lock (reference 3) slightly outwards until you hear an audible clicking sound.

  4. Take the lens assembly out of its packing material and remove both lens caps from the lens.

    Caution: There are two lens caps on every new lens. One on the side of the projected surface, and one on the side of the lens holder.

    Damage may occur to the lens and/or the projector if the lens is installed while the lens cap on the lens holder side is not removed.

  5. Gently insert the projection lens in the lens holder while aligning the lens connector with the electrical socket (reference 2) until a click is heard.

    Warning: Do not release the lens yet, as the lens may fall out of the lens holder.

  7. Check if the lens is secured by trying to pull the lens out of the lens holder.
Warning: In case the projector is installed above the head of people, then the projection lens must be secured with a lens safety cable. See chapter “Installing the lens safety cable”.
