CAUTION: Replace the xenon arc lamp when the cumulative operating time of the lamp has exceeded 2,000 hours.
The xenon arc lamp may explode if it used passed its service life of 2,000 hours.
It is dangerous if the xenon arc lamp explodes and units surrounding the lamp may be damaged.

 

1. Checking the Cumulative Operating Time of the Xenon Arc Lamp

  1) Connect LabSolutions RF to the RF-6000. 

  2) Check the cumulative operating time of the xenon arc lamp in the instrument status displayed on the upper right of the screen.

   

    NOTE: If the cumulative operating time of the xenon arc lamp exceeds the service life time, the color of the mark on the instrument status changes to red. In this case, immediately replace the xenon arc lamp with a new one.

 

2. Replacing the Xenon Arc Lamp
  WARNING: When handling the xenon arc lamp, always wear the following protective gear: a protective mask, thick long-sleeved shirt, and safety gloves
    • The xenon arc lamp is filled with high-pressure gas. If the xenon arc lamp is subjected to a strong impact or the glass part is damaged, it may explode and scatter fragments.
    • Use a protective mask that covers your entire face with rigid plastic or similar material.
    • If you happen to touch the glass part with your bare hands, use a piece of gauze, or other suitable material, moistened with ethanol to wipe off any fingerprints. If the xenon arc lamp is lit with fingerprints on the glass part they will burn and may cause the lamp to explode.

    • Always turn power to the instrument OFF and unplug the power plug before replacing the xenon arc lamp. An extremely dangerous high voltage of around 30 kV is applied to the positive (+) terminal of the xenon arc lamp at the start of ignition.

    • Make sure that the xenon arc lamp has cooled sufficiently before attempting to replace it.
      The xenon arc lamp is extremely hot immediately after being turned OFF and touching it may result in burns.
      The time required for the xenon arc lamp to cool is at least 90 minutes when turning OFF power to the instrument, or at least 30 minutes when manually turning OFF the lamp and leaving power to the instrument turned ON.
      In the case when cooling the xenon arc lamp with the power to the instrument is left turned ON, always turn OFF power to the instrument and unplug the power plug before replacing the xenon arc lamp.

  CAUTION: When replacing the xenon arc lamp, take care not to drop any screws. Otherwise, instrument failure may result.

  1) Stop the RF-6000.

  2) Disconnect the male power plug from the power outlet.

  3) Wait until the xenon arc lamp has cooled down.
  4) Loosen the two fixing screws on the lamp housing cover and remove the cover.

   

  5) Remove the knurled nut at the top of the xenon arc lamp and then remove the power cord terminal (white) from the terminal of the xenon arc lamp while removing the stopper pin from the designated position.

    CAUTION: Always turn the knurled nut by hand. Using a tool like a wrench may break the xenon arc lamp.

   

  6) Completely loosen the two fixing screws on the lamp unit using the provided spanner, grip the lamp unit pullout handle, and pull the lamp unit out of the instrument.

   

    HINT: After pulling out the lamp unit, insert the power cord stopper pin removed in step 5 back into the same hole to facilitate the replacement work.

   

  7) Remove the single hexagon spacer using the provided spanner and then remove the xenon arc lamp.

   

  8) Install the xenon arc lamp by aligning the two positioning pins of the lamp unit and then tighten the single hexagon spacer in place with the provided spanner.

   

  9) Grip the handle and return the lamp unit to its original position and then tighten the two fixing screws on the lamp unit using the provided spanner.

  10) Connect the power cord terminal (white) to the terminal of the xenon arc lamp while setting the stopper pin to the designated position and tighten the knurled nut at the top of the xenon arc lamp.

    CAUTION: Always turn the knurled nut by hand. Using a tool like a wrench may break the xenon arc lamp.

   

  11) Attach and fix the lamp housing cover with the two fixing screws.

 

3. Resetting the Lamp Cumulative Operating Time

  1) Connect LabSolutions RF to the RF-6000.

  2) Click [Configure Instrument] on the [Instrument] menu. The [Configure Instrument] window is displayed.

  3) Click the [Light Source Status] tab and then click [Reset] to the right of [Arc Lamp Lighting Time].
