Operation of ELC
4.1 Initial
operation
The operative parameters of the ELC, such as the scope of the trigger pulse when switching
on the lamp, is set by the manufacturer.
Alterations to the manufacturer’s settings can only be carried out by the
manufacturer. Adjustment to the internal potentiometer can cause malfunction
and damage to the equipment and is therefore prohibited.
You always have to ensure that the correct lamp type is used (see chapter 6) and that all
wireing is properly connected !
4.2
Switching on the ELC
•
The ELC is switched on by applying the operating voltage.
4.3
Switching on the lamp
•
A HIGH signal is applied to the digital START control input to switch on the lamp.
If a HIGH signal has already been given to the digital START control input before
the ELC is switched on, then the lamp will not start up. In the case of a power
failure, the ELC cannot automatically switch on the lamp when power returns.
Before switching on the lamp, a LOW signal must be applied to the digital control
input.
Turn the ELC on maximum lamp power during the lamp warm-up period.
Maximum lamp power can be adjusted as follows:
•
HIGH signal at the digital MAX control input or
•
10 V control voltage at the analogous SET VALUE control input.
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 power until the nominal power is reached.
