Troubleshooting; Fixture Cleaning - ACME LED-BL4B User Manual

when one of the units' power is disconnected.
3. At last fixture, the DMX cable has to be terminated with a terminator to reduce signal
errors. Solder a 120-ohm 1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a
3-pin XLR-plug and plug it in the DMX-output of the last fixture.
4. Each lighting fixture needs to have an address set to receive the data sent by the controller.
The address number is between 0-511 (usually 0 & 1 are equal to 1).
5. 3 pin XLR connectors:.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)

8. Troubleshooting

Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The fixture does not work, no light
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if link properly.
2. If the DMX LED is on and no response to the channel, check the address settings and DMX
polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB of
the fixture or the previous one.
4. Try to use another DMX controller.
5. Check if the DMX cables run near or run alongside to high voltage cables that may cause
damage or interference to DMX interface circuit.

9. Fixture Cleaning

The cleaning of internal must be carried out periodically to optimize light output. Cleaning
