  • Page 23 XENON NOVA ® MODEL 20 1315 20 Lamp timer circuit The lamp timer circuit keeps track of lamp usage in hours, and warns the operator that a scheduled lamp change is approaching or overdue. The red LED (D902) on the faceplate will light at approximately 450 hours (90% of the lamp’s expected life) and start blinking at around 500 hours to indicate a lamp change is imperative.
  • Page 24 XENON NOVA ® MODEL 20 1315 20 Ignition circuit When the lamp is off, the full B+ voltage through R600 is across the sidac D600 and capacitor C600. When the sidac reaches 95 V, it discharges the capacitor through the L600 inductor (a high-voltage transformer), which through C601, D601, and D602 successively pump charge into capacitors C602 and C603.

    XENON NOVA ® MODEL 20 1315 20 3.2.5. Light attenuator This device attenuates the light output. 3.2.6. 175 W Xenon lamp The lamp always runs at the same power. Turning the brightness control knob does not affect the lamp output; therefore, the lamp lifetime is the same at any brightness level. If the lamp has run for more than 450 h (90% of the lamp’s warranted life of 500 h), the REPLACE LAMP indicator will light while the light source is on.

  • Page 42: Component Courses Of Action

    XENON NOVA ® MODEL 20 1315 20 General complaint of low brightness – Examine all other parts in the optical system, including the light guide cable, the endoscope, the video camera and lenses. – Measure the power (in W) required by the lamp. Measure the voltage across the R206 resistor and multiply the value by 100.
  • Page 43 (e.g., the REPLACE LAMP indicator comes on in a few days). • If the replace lamp indicator lights before 450 hours have elapsed, inspect U903. • If U903 is not 54/74HC4017, call KARL STORZ customer service and order a lamp power supply upgrade kit (order no. 201315 80). Install the kit as directed. Visually observe the D903 yellow LED located inside the power supply area next to the battery. With the light source running, the D903 LED should blink at a rate of 2.44 times per second (37 pulses in 15...
