Use
CHANGE LAMP
to record the serial number for a newly installed lamp:
In the
Lamp S/N
window, use the number text entry keys to record the new lamp serial
number and press
again to accept the change. See
Using Slide bars and Other
Controls
if you need help entering the number. Once entered, the new lamp serial
number will be added to the
Lamp History
menu and the
Lamp Hours
timer will reset
to “0”.
Lamp Mode
and
Lamp Limit
remain as they were for the previous lamp and
can be changed at any time. See Figure 3.12.
Figure 3.12. Recording the New Lamp Serial Number
NOTE:
Enter a serial number only if you have just installed a new lamp. This will
help ensure that lamp timer is not reset on an old lamp and that the number of hours
logged on the lamp will be accurate.
IMPORTANT:
Always record the serial number of a NEW 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.
If the “Lamp Message” checkbox has been enabled in the
Lamp
menu
(recommended), an expiry message will appear upon power-up when the lamp has
reached its defined “Lamp Limit”. In addition, the LED’s next to the built-in keypad
will flash “LP” when lamp time has expired. The lamp should be replaced.
The “Lamp Limit” setting should not exceed the expected lamp life, as an old lamp
becomes increasingly fragile and more prone to sudden failure. See also
4.4, Lamp
and Filter Replacement.
