3.10.8 How Old is My Lamp?
When a new lamp is installed and its serial number recorded by
selecting "Change Lamp" in the Lamp menu, the lamp timer
resets to "0" and begins logging time for the new lamp. This tally
appears in both the
Lamp menu (see right) and the Status menu.
To review the number of hours logged for previous lamps, consult
the
Lamp History menu.
3.10.9 When to Replace the Lamp
If the Lamp Message check box has been enabled in the Lamp
menu (recommended), an expiry message appears upon power-up
when the lamp has reached its defined Lamp Limit. The lamp
should be replaced.
The Lamp Limit setting should never exceed the lamp’s lifetime warranty by more than 20%, as an old lamp
becomes increasingly fragile and more prone to sudden failure or even explosion, which can be damaging as
well as dangerous. These maximum limits depend on the lamp size. See Table 3.7
.
3.11 Status Menu
The read-only Status menu lists a variety of details about the standard and optional components currently
installed in the projector. Refer to the
Status menu for versions of hardware and software installed, the type
(size) of lamp defined in projector memory, its current, voltage and hours logged in total and for a specific
period (such as a rental period), and for your projector model name and serial number. In addition, the
Status
menu identifies the current channel, its location, its frequencies and other details.
Scroll the full
Status menu using the UP ARROW and DOWN ARROW. Use the LEFT ARROW and the RIGHT ARROW
for page up/down.
3.12 Using Multiple Projectors
When an installation requires multiple projectors, you can use the RS-232 and/or RS-422 serial ports to daisy
chain the units together and control the group with a single keypad, remote or a computer/controller connected
to the first projector. In such a network, you can choose to broadcast commands to the entire group, or use the
PROJ key as desired to limit responses to an individual projector. Or you may prefer that each projector in an
installation stands alone and responds only to a unique transmission protocol from its own remote.
Alternatively, you may want to add projectors to an Ethernet network.
NOTE: Refer back to Section 3.8 Adjusting System Parameters and Advanced Controls for complete
information about communicating with multiple projectors.
