Fixture Cleaning - Nicols SPARK LED Manuel D'utilisation

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.
C. Some fixtures don't respond to the easy controller
1. You may have a break in the DMX cabling. Check the LED for the response of the
master/ slave mode signal.
2. Wrong DMX address in the fixture. Set the proper address.
D. No response to the sound
1. Make sure the fixture does not receive DMX signal.
2. Check microphone to see if it is good by tapping the microphone.
E. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor's drive IC on the PCB might be out of condition.

8. Fixture Cleaning

The cleaning of internal must be carried out periodically to optimize light output. Cleaning
frequency depends on the environment in which the fixture operates: damp, smoky or
particularly dirty surrounding can cause greater accumulation of dirt on the fixture's optics.
- Clean with soft cloth using normal glass cleaning fluid.
- Always dry the parts carefully.
- Clean the external optics at least every 20 days. Clean the internal optics at least
every 30/60 days.
