American DJ Sonic Beam II - Manual (Page 6)

Listed below are a few common problems the user may
encounter, with solutions.
No light from the unit;
1. Check if the ‘Power On’ (red) LED is lit and the fan is
running. If not, there is no main supply.
2. Check the fuse in the back panel.
3. Check if lamp is lit. The user should be able to see some
light escape through the fan. If power is present but the
lamp is not lit, lamp may need to be replaced.
Note: The unit has been designed to shut the lamp down
after 60 seconds of inactivity. This is a way of extending
lamp life, be assured this is not a problem with the fixture.
Unit not responding to DMX;
1. If the Green LED on the top of the unit is flashing, the unit
is definitely receiving DMX
2. Check the dip switch settings.
3. If the DMX LED is not lit, check that the DMX cables are
connected properly and are wired correctly (pin 3 is
‘hot’; on some other DMX devices pin 2 may be ‘hot’).
Also, check that all cables are connected to the right
connectors; it does matter which way the inputs and
outputs are connected.
4. If it is a bad connection, the Green LED may flash when
cables are wiggled (but remember it may also be the
unit sensing audio!)
5. If DMX connectors are fairly short, ordinary microphone
cables may be used. For longer runs, this may cause
data transmission problems (which will show up as
random or incorrect movements) for best result, use
proper balanced data transmission cable.
Unit does not respond to sound;
1. Check to see if the unit is receiving DMX (the green LED
should be off).
2. Tapping the microphone should cause the LED to flash
(quiet or high pitched sounds will not activate the unit).
If the green LED does not flash to sound there may be
an internal problem.
Unit blacks out in stand alone mode;
1. Some of the units’ built-in patterns include special
effects such as blackout sweeps. When connecting two
units up, only one is ever blackened out at once, and
the blackout ‘swaps’ between the units.
