4.1 Introduction
Lamp and Lamp House
The DPxK-19B/23B/P projector is delivered with a manual or motorized S/M Lamp House without lamp. The
xenon bulb lamp is delivered separately and has to be installed on site by a qualified service technician.
The xenon bulb lamp is packed in a protective container or wrapped in a protective cloth. Never remove this
protective container or protective cloth without wearing adequate protective clothing (face shield, clean cotton
gloves, welder's jacket).
Image 4–1 Left: Xenon lamp in protective container. Right: Xenon lamp wrapped in protective cloth.
CAUTION: Xenon compact arc lamps are highly pressurized. When ignited, the normal operating
temperature of the bulb increases the pressure to a level at which the bulb may explode if not
handled in strict accordance to the manufacturer's instructions. The bulb is stable at room
temperature, but may still explode if dropped or otherwise mishandled. Whenever the lamp house,
containing a xenon lamp, has to be dismantled or whenever the protective container or cloth has to
be removed from the xenon lamp, authorized protective clothing MUST be worn!
Lamp strike policy and lamp warning/error policy versus the lamp runtime
• The projector issues a lamp run time notification message (end have blue status LEDs) approximately 30
hours before the maximum lamp runtime occurs.
• The projector issues a lamp run time notification message (end have blue status LEDs) when the
maximum lamp runtime occurs.
• The projector will always try to strike the lamp, independent of the lamp runtime.
