7.3.1 Behavio r on Lamp Failure
Lamp failures can only be detected if the lamp is running!
Lamp failures set the Lamp Error Flag
In case Error Box is enabled (cf. Error Box), 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

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 remains 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 sys-
tem 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.
