7.3.1
Behavior on lamp failure
Lamp failures can only be detected if the lamp is running!
Lamp failures set the Lamp Error Flag.
It is recommended to first reset the flag without replacing the lamp and to retry ignition
after a few minutes. Since the lamps are UHP lamps, e.g. a fluctuation in power voltage
will shut down them and set the error flag although the lamps are still ok. Therefore
always try re-ignition before replacing.
In case
Error Box
is enabled (cf.
), after the detection of a lamp failure the following warning pops up:
Warning
Error on Lamp Bottom occured.
Has the error been solved?
Press <enter> for yes,
<back> for no.
Figure 7-1
Warning on Lamp failure
In case this message is acknowledged
YES
, the system requires confirmation:
Warning
Are you sure the lamp is
- intact?
- well connected?
Press <enter> for yes,
<back> for no.
Figure 7-2
Confirmation on lamp replacement
In case of a positive acknowledge, the
Lamp Error Flag
is reset.
In case the warning on lamp failure has not been positively answered, the
lamp error
stays saved.
The lamp operation mode is still valid, but the lamp lift can no longer be moved.
Press the On/Res. switch for about 6 sec. on the rear of the system to reset the error.
In
Hot Standby
mode, after resetting the error, the lamp is ignited. If ignition is successful and the lamp has
been switched on, the lift can be moved again. If ignition is a failure, the lamp error is set again and the lift re-
mains locked.
In
Cold Standby
mode, since the replaced lamp is the inactive lamp, after resetting the error, there is no lamp
check, and the lamp remains switched off. The lift can be moved again. If then the system changes the active
lamp by means of the lift, the new lamp is tried to be lighted. If it is a flop, the error flag is set again, and within
about 5 seconds, the projector switches back to the lamp which has been the active one. Then the lift is locked
again.
In Cold Standby, after switching the active lamp, the lamp which has been active at that
time is only switched off if the second lamp succeeds in being switched on.
