Lamp house 50
The lamp house 50 can hold either the XBO 450W Xenon lamp or
the HBO 200 W/2 mercury-vapor high-pressure lamp
Installation of the XBO 450W/2 Xenon lamp:
PLEASE NOTE! Before opening the lamp house, unplug
the connection cable.
The lamp contains a pressure of several atmospheres. For safety
reasons it therefore required to put on a protective mask and put
on gloves with cuffs when the cover is removed from the lamp.
Touch lamp only by the posts. If the quartz body was accidentally
touched immediately clean with alcohol and then with distilled
water. For reasons of operational safety, change the lamp when a
maximum of 25% of the average life has been exceeded; please
note the operating instructions of the lamp.
⚫ Use the coin screw
➀
to open the lamp house.
⚫ Insert the lamp with protective cover into the bracket
➃
, with
the plus end up. The flexible cables should be attached to the
terminals with hex nuts. The cables are there so that no forces
act on the lamp, and they should not touch the walls, due to
danger of a short-circuit.
⚫ Clamp the lamp into its holder with the setscrew
➂
⚫ Don face protection and gloves, and remove the lamp cover
⚫ Close the lamp house and tighten the coin screw
Note: If the flexible cables are more than 100mm long, and are
not carefully arranged, then the lamp may fail to ignite, since the
cables may short out to the metal housing
Installation of the mercury-vapor high-pressure lamp HBO
200W/2:
PLEASE NOTE! Before opening the lamp house, unplug
the connection cable.
⚫ Handle the lamp carefully to prevent mechanical damage.
Touch lamp not on the quartz body, but by the metal ends. When
tightening the lamp, always hold the respective base so no
turning or bending forces act on the quartz body. Before first use,
clean the quartz body with a clean cloth and alcohol, since
fingerprints on the quartz will burn. For reasons of operational
safety, change the lamp when a maximum of 25% of the average
life has been exceeded; please note the operating instructions of
the lamp.
