7.3 Replac ement of Lamp Modules
In case of a lamp failure, the respective status LED (lamp top: top LED, lamp
bottom: mid LED) blinks slowly red.
The power LED blinks slowly green to indicate a non critical error. For
acknowledge, push up the standby switch for 6 seconds.
Lamp failures can only be detected if the lamp is running.
OVERVIEW CDG67-DL is designed as a dual lamp system. In case a lamp is broken, replace it im-
mediately to ensure to have a good lamp in case the other lamp fails, too.
If there is no lamp for replacement on stock, DO NOT remove the broken lamp. The
cooling concept requires that two lamps are installed!
After the replacement of a lamp module, the new serial number has to be entered, and the lamp
optimization procedure has to be carried out, cf.
Reset runtime, Lamp Optimization.
Bevor replacing a lamp module, this lamp has to be inactivated!
Only open the lamp door when the lamp door LED shines red!
