In
Hot Standby
both lamps are on. In case of a lamp failure, the light output of the other lamp is immediately
switched to illuminate the optics, and there is almost no noticeable effect on the displayed information: no loss
of information, no impact on quality. Switching time is about one second.
In
Cold Standby
mode the second lamp is only switched on in case a failure occurs with the active lamp. Since
the second lamp needs about one minute to reach a stable operating temperature, at the beginning the display
will have reduced brightness. The contents of information, however, is available nearly without interrupt.
Auto Switch
mode is a special version of the
´Cold Standby
mode: the lamps are active in turns. Since the lamp
is switched on some minutes in advance, the takeover of the other lamp is equally percepted as in
Hot Standby
mode: no noticeable effect on the displayed information, no loss of information, no impact on quality.
The lamp activation time can be selected between 12 hours and 500 hours. Therefore when selecting
Auto
Switch
, a dialog pops up to enter the auto switch cycle time:
