Before starting the lamp it is necessary to write the desired lamp power into the register
[Power Set Value]
in Watts. To transfer the lamp and its surrounding into a thermally
stable condition, it is recommended to choose the maximum lamp power for
[Power Set
Value]
during the lamp run-up period.

To ignite the lamp set the

After switching on the ELC take account of the charge time given in chapter 6,
before starting the lamp.
In case of an error the ELC will not try to ignite the lamp. After eliminating the error
the
[Error Register]
has to be cleared additionally (see paragraph 5.4).
As long as the safety circuits are not activated the ELC will not try to ignite the
lamp (see paragraph 5.3).
During warm-up the lamp power stays at a very low level over a longer period of time and after
approximately 60 seconds rapidly increases to its nominal power. The lamp is operated with
increased current until the nominal power is reached.
The actual condition of the lamp may be read out via the display (only actual power and power
set value), and also from register
[Lamp Status]
of the PROFIBUS-input-data.
