The unit does not work, no light Check the mains connection and the main fuse.

No response to the DMX con‐

troller

1. When the display ashes, e.g. ‘d001’ , no valid DMX

signal is received. Check whether the DMX controller is

switched on. Check the DMX connectors and cables for

proper connection.

2. If the display is not ashing but there is still no

response, check the address settings and the DMX

polarity.

3. Try using another DMX controller.

4. Check whether the DMX cables run near or parallel to

high-voltage cables that may cause damage or interfer‐

ence to a DMX interface circuit.

If the procedures recommended above do not succeed, please contact our Service Center. You
