OPERATION
NOTES: 1) Setting the
lamp size requires a
qualified technician.
The required password
for access is a service
option that may be
turned off. 2) Current
lamp size should also
be recorded on the
"Lamp Installed" label
located on the lamp
door—see right. Mark
Figure 3.25. Use the "Lamp Installed" Label
the appropriate lamp
size using a small blue dot label (see inside cover of this manual), or mark with a
dry-erase pen.
If the projector is already running, consult the Status menu to see which lamp size is
currently recorded in projector memory. If this does not match the installed lamp, you
can either change the Lamp Size setting in the service password-protected Service
menu, which implements the new size at the next power-up, or you can power down
Menu
and press to use the LCD for lamp selection as described above (passwords are
shown in Figure 3.24. Always indicate current lamp size on the Lamp Installed label.
Note that any of the lamps can be powered by the 7kW ballast, but only the 2.0 kW
and the 3.0 kW lamps can be powered by the 3 kW ballast (available in 2005).
Lamp Cable Lengths
'
The high-voltage DC cables connected between the lamp ballast and the rear of the
projection head can be 2-30 meters in length, depending on your site requirements
and setup. The length currently in use must be defined in projector software for any
new installation—this setting compensates for the voltage drop that occurs over
distance and ensures that the proper voltage is maintained at the lamp. In the Lamp
menu, set the "Cable Length (m)" slidebar to match that of your DC cables. By
default from the manufacturer, this setting is 8 (approximately 25 feet). See Figure
3.26.
