Legend™ 4500 User Manual
Clean the fixture regularly to avoid any such failure. This fixture is convection
cooled, which means that if the surface is kept clean and free of debris, then
proper cooling will be allowed to occur
An LED may have failed, resulting in an open circuit. In this event, all of the
red, green, or blue in a single module will no longer illuminate. This does not
mean that all of the LEDs have failed, but the circuit is wired in series.
An LED may have failed, resulting in a short circuit. In this event, only the
single LED which has failed will no longer function. This does not mean that all
of the LEDs have failed, but the circuit is wired in series.
-Note: In the event of LED failure, a replacement LED PCB assembly may be
purchased directly from Chauvet
Check that the lens assembly is installed properly. If the lens assembly is not
aligned properly over the LEDs, then they will not project fully
-See section on Lens Assembly Installation
-Note: In the event of LED failure, a replacement LED PCB assembly may be
purchased directly from Chauvet
Check total load placed on the electrical circuit
Check for a short in the electrical wiring: internal and/or external
Check device's fuse (internal)
Check for power on Mains
Check cable connections The Legend™ 4500 IP-66 cables must be firmly
connected and locked in place for operation
-Note: In the event of autoswitching transformer failure, the unit can be sent in
for repair; however, a replacement part can be ordered directly from Chauvet
Check Control Panel settings for correct addressing
Check DMX cables
Check polarity switch settings on the controller
Check cable connections
Call service technician
-Note: In the event of Display/Master PCB failure, a replacement PCB can be
ordered directly from Chauvet
Use only DMX cables
Install terminator
Note: Keep DMX cables separated from power cables or black lights
1 or more sensors may need to be replaced. This may be either the optical
sensor or the magnetic stopper sensor.
Note In the event of a sensor failure, a replacement sensor may be ordered
directly from Chauvet:
1 or more sensors may need to be adjusted. This should be done by a
qualified technician, as it involves opening the case of the fixture and
modifying internal components.
There is an option in the control board that determines if the display turns off
after 60 seconds of inactivity, or if the display stays lit indefinitely.
-See section 1.6 in the onboard display "close".
