DC3100 33
Figure 34 Error Message
The following table summarizes possible errors:
The current of the LED was
reduced to the set current limit.
This can happen in the
'External Control Mode', when
a voltage was applied to the
external trigger input at the rear
side representing a current,
which is higher than the limit.
Decrease the input voltage.
The temperature within the
DC3100 case reached the
maximum limit and the LED is
switched off.
Make sure that the ventilation
slots are not covered. It is
necessary to ensure an air
ventilation through the DC3100
unit.
