Service and maintenance

Warning! Read "Safety Information" on page 5 before servicing this light

Warning! Disconnect the fixture from AC mains power and allow to cool for at least 10 minutes before

handling. Do not view the light output from less than 4 meters

prepared for the fixture to light suddenly if connected to power.

Warning! Refer any service operation not described in this user manual to a qualified service

technician.

Important! Excessive dust, smoke fluid, and particle buildup degrades performance, causes overheating and

will damage the fixture. Damage caused by inadequate cleaning or maintenance is

not covered by the product warranty.

Following are a few common problems that may occur during operation. Here are some suggestions

for easy troubleshooting:

A. The unit does not work, no light and the fan does not work

1. Check the connect power and main fuse.

2. Measure the mains voltage on the main connector.

3. Check the power on LED to see if it can be light up or not.

B. Not responding to DMX controller

1. DMX LED should be on. If not, check DMX connectors, cables to see if they are linked 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 unit or the

previous one.

4. Try to use another DMX controller.

5. Check to see if the DMX cables run near or run alongside to high voltage cables that may cause damage

or interference to DMX interface circuit.

C. 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.

D. The lamp is cutting out intermittently

1. The lamp is not working well. Check the mains voltage either too high or too low.

2. Internal temperature may be too high. Check if replacement of fan is needed on the head.
