DC4104
Message Text Explanation and Impact Elimination
Clipped to
Limit Error The current of the specified chan-
nel was reduced to the set current
limit. This can happen in the 'Ex-
ternal Control Mode', when a
voltage was applied to the external
trigger input representing a cur-
rent, which is higher than the limit. Decrease the input voltage.
LED Open Er-
ror
The LED is switched off, because
the maximum forward voltage was
reached. If a LED with more than
5V forward voltage was connected
this error can occur. Only LEDs with a forward voltage
below or equal to 5V can be driven
with the DC4104.
The forward voltage depends on
the actual current. Reduce the cur-
rent to a forward voltage level of
5V or less.
Over Tempera-
ture Error
The temperature within the
DC4104 case reached the max-
imum limit and all channels are
switched off.
Make sure that the ventilation slots
are not covered. It is necessary to
ensure an air ventilation through
the DC4104 unit.
Software In-
stallation
failed
The software cannot be installed
on the computer.
Be sure to have administrative
rights on your computer, which
enables you to install software at
all. Ask your system administrator
to give you such rights or to do the
installation himself.
LED cannot
be switched
on
After pressing the LED button the
LED does not emit light. Check if the LED current is set to a
value larger than 0mA.
A LED can only be switched on if
one of the 3 operation modes is se-
lected.
