EQUIPMENT HANDLING
Proper Lamp Servicing and Operation
Servicing
+
When handling a lamp, hold it by the ceramic base while wearing cotton gloves or finger cots. Do not touch the
glass envelope (bulb). If you touch the glass with bare fingers, wipe off any fingerprints with alcohol.
Heat
+
When lamps are lit, the interior of the luminaires becomes very hot. To aid in the airflow circulation within the
luminaires, after dousing the lamps, wait ten minutes before removing power to the luminaires. This will provide
enough time for the equipment fan to cool off the unit.
Lamp Life
+
When operating arc lamps, allow luminaires to operate for at least 3 minutes. It takes about 3 minutes for the fill
components (mercury and halogen-metal compounds) in the lamp tubes to vaporize completely. If the lamps are
switched off earlier than 3 minutes, the fill components are partially vaporized. The inadequately vaporized fill
components and the electrode material (tungsten) are deposited in the areas of the lamp tubes that have
remained cool. As a result, the lamp tubes blacken prematurely and reduce the service lives of the lamps.
+
If system will be unattended for more than 3-4 hours, luminaire lamps should be doused. Standby mode should
NOT be used for more than 3-4 hours (only applies to systems using an SPC-36 Controller).
Proper Lamp Douse
+
The lamp douse switch should be used to douse the arc lamp before disconnecting the pigtail cable. This will
prevent damage to the contacts in the CPC connector, which can be caused by drawing an arc during
disconnect. To douse the lamp, press the lamp douse switch located at the yoke cross-member. (Refer to
