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.
Overheat ballast resulting in premature failure or
damaged ballast.
The ballast incorporate internal automatic-resetting thermal
protection, which deactivates the ballast should it overheat.
Normal operation resumes once the ballast has cooled
sufficiently. Burned-out or failing lamps, or high temperatures
in or around the fixture, can cause the ballast to overheat, so
we need solve the problem and replace components as
required.
Shaking, wrong
position, and out of
control gobo wheel
No function the connector between gobo wheel
motor and drive, loose, damaged, or broken
cables connecting the gobo wheel and drive.
Reconnect the gobo wheel motor to the drive, and replace
cables as required.
The gobo wheel motor's drive IC on the PCB
might be out of condition.
Replace the drive having the same software version as
required.
Dislocated magnetic tube and positioning
magnet, or damaged magnetic tube.
Calibrate the position of the magnetic tube to the positioning
magnet, and replace magnetic tube as required.
Shaking motor, wrong rotation angle, losing step
or damaged motor.
Replace the motor as required.
