How to Respond to an Alarm Window

Press the Acknowledge button from the alarm window to hide the window and enable access to other menus in
order to solve the problem. Each alarm window indicates a new condition. The alarm window does not
reappear for a condition that is acknowledged and not yet solved. However, when the projector is cycled OFF
and ON, any persisting alarm condition triggers the alarm window again.

Setting Alarm Triggers

From the Preferences tab in the Advanced menu, certain alarm triggers can be enabled or disabled (i.e., Over
Temperature, Fan Fail, Lamp Rotation). Although it is highly recommended the monitored over-temperature
and fan conditions always be enabled (default), these triggers can be turned OFF by disabling the appropriate
Alarm Triggers checkbox. Once disabled, such conditions only trigger a change of the status indicator in the
main toolbar and do not display the alarm window. It is not recommended to disable alarm triggers for normal
operation. Failed interlocks, communication faults, DMD over-temperature and lamp failures always result in
an alarm window. These conditions cannot be turned OFF. NOTE: The default setting for Lamp Rotation is
disabled.
