  6. Troubleshooting 

 

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. 

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 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. Some units 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 unit. Set the proper address. 

D. No response to the sound 

1.  Make sure the unit is not receiving 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. 

F. The lamp is cutting out intermittently 

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

 

21- 

2.   Internal temperature may be too high. Check and if necessary replace the fan on the   

head. 

G. If The pan belt is broken 

1. Turn off the main power. 

2. Unscrew all the screws (A) and open the base-housing cover (B). 

3. Unscrew all the screws (C) and open the arm cover (D). 

4. Unplug all the connect wires that from the arm to the bottom. 

5. Unscrew the screws (E) and remove the fixture head. 

6. Loose the screws (F), then loose the screws (G). 

7. Change a new belt (H) , put the belt around the axis gear and motor gear. 

8. Screwed the screws (G), install the new belt and adjust the belt tension properly. Note: do 

not fix belt too tight as it is easy to rupture. 

9. Plug all the connect wires back that form the bottom to the arm. 

10. Reverse the procedures from point 5 to point 2.
