happens, please check that the fans are not blocked, and clean them if they are dirty. Check whether the fans are
operational. If not, call a qualified technician. Troubleshoot and correct the problem before switching on the fixture
again. Any maintenance work should only be carried out by qualified technicians.
To ensure the continuous rotation of the rotating gobos and linear motion of the focus lens, it is recommended that the
bearings on the rotating gobos and the 2 shafts for the focus system is lubricated periodically, preferably every 3-6
months. Use only high quality, high-temperature resistant grease. When lubricating the bearings, a syringe with a fine
needle is the best way to grease the bearings around each gobo. Be aware not to use too much grease, and stain the parts
around.
Troubleshooting
Problem
Possible Cause
Suggested Correction
No response after
connected to A/C
power
Power switch not turned on.
Turn on power switch.
Take out the fuse and check if it is blown.
Locate the blown fuse. Remove the broken fuse. Insert a
replacement fuse of the correct amperage.
Abnormal A/C input (A/C power socket, power
cables, luminaire power socket).
Replace AC power socket and power cables, and then adjust
power socket for proper connection.
No DC voltage from switching power supply.
Check if the switching power supply has DC voltage output.
Replace the switching power supply.
No response or
wrong response to
the commands of
the control system
DMX cables disconnected from fixture’s DATA
IN connector.
Connect DMX cable to the fixture’s DATA IN connector.
Open circuit or short circuit fault in the DMX
cables.
Replace DMX cables as required.
Wrong DMX address for the fixture in the
control system.
Ensure the address in “Run setting > Address Setting >
Address” of the fixture is consistent with the address in the
control system.
Misuse in “Channel setting > Channel Mode” of
the fixture.
Choose the channel mode in “Channel setting > Channel
Mode” of the fixture as required by the user.
Malfunctioning of DMX cannon input/output
connectors. No input/output voltage to the
main control board of the fixture.
Troubleshooting the DMX XLR signal plate of the fixture,
replace the main control board of the fixture.
The lamp does not
start when switch is
turned on
Normal end of lamp life.
Test the lamp in an adjacent fixture which is known to be
operating properly and then replace as necessary.
Shorted leads between ballast and the lamp.
Replace components as required.
Incorrect ballast output.
Check ballast output to determine if it conforms to lamp
requirements. If voltage and current do not stabilize in five
to ten minutes warm-up time, ballast output is incorrect and
adjustment should be made. Check capacitor wiring, if
visibly available, to determine if capacitors are properly
wired.
The lamp is off
unexpected
The fixture is in sleep mode.
Should the fixture is not in active use for “standby time”, the
sleep mode is enabled automatically to make it more stable
and safer, sleep time can be customized.
Lamp has been operating: cool down time
insufficient.
Environmental conditions such as extreme temperatures
will have the fixture stop working, the lamps will require a
period of time to cool and re-establish optimum starting
conditions. Restart time varies with the degree of ventilation
built into it, ambient temperature, and draft conditions.
