7. Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors must be carried out
periodically to optimize light output. Cleaning frequency depends on the environment in which
the fixture operates: damp, smoky or particularly dirty surrounding can cause greater
accumulation of dirt on the unit’s optics.
ŸClean with soft cloth using normal glass cleaning fluid.
ŸAlways dry the parts carefully.
ŸClean the external optics at least every 20 days. Clean the internal optics at least every 30/60 days.

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 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. Check the unit that is not receiving DMX signal.
2. Check the unit that is not set to display mode
3. 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.
2. Internal temperature may be too high. Check and if necessary replace the fan on the head.
Warning
lTo prevent or reduce the risk of electrical shock or fire, do not expose the unit to rain or moisture.
lNever touch bulb with bare fingers as it is very hot after using.
lHot lamp explosion hazard. Do not open the unit within five minutes after switching off.
lDo not start on the unit without bulb enclosure or housing are damaged.
lThe housing, the lenses, or the ultraviolet filter must be replaced if they are visibly damaged.
lDo not look directly at the light while the bulb is on.
Caution
There are no user serviceable parts inside the unit. Do not open the housing or attempt any
repairs yourself. In the unlikely event your unit may require service, please contact your nearest
dealer.
Installation
The unit should be mounted via its screw holes on the bottom of the base. Use clamps to fix the unit to truss.
Always ensure that the unit is firmly fixed to avoid vibration and slipping while operating. Always ensure that the
structure to which you are attaching the unit is secure and is able to support a weight of 15kgs for each unit.

1. If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pin adapter-cable.
2. At last unit, the DMX cable has to be terminated with a terminator. Solder a 120 ohm 1/4W resistor between
pin 2(DMX-) and pin 3(DMX+) into a 3-pin XLR-plug and plug it in the DMX-output of the last unit.
3. Connect the unit together in a `daisy chain` by XLR plug from the output of the unit to the input of the next
unit. The cable can not be branched or split to a `Y` cable. DMX512 is a very high-speed signal. Inadequate or
damaged cables, soldered joints or corroded connectors can easily distort the signal and shut down the
system.
4. The DMX output and input connectors are pass-through to maintain the DMX circuit, when power is
disconnected to the unit.
5.Each lighting unit needs to have an address set to receive the data sent by the controller. The
address number is between 0-511 (usually 0 & 1 are equal to 1).
6.The end of the DMX512 system should be terminated to reduce signal errors.
7.3 pin XLR connectors are more popular than 5 pin XLR.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)

5.2 Easy Controller
The easy remote control is used only in master/slave mode. By connecting to the 1/4” microphone jack of
the first unit, you will find that the remote control on the first unit will control all the other units for Stand by,
Strobe/Next and Fast/Slow function.
1.STAND BY: To blackout all the unit.
2.STROBE/NEXT : Under FAST mode, the light will strobe in three different ways:
a.) Strobe in different gobos and colors.
b.) Synchronous strobe in white color.
c.) Two-light strobe in white color.
If the unit in slow mode, press NEXT button to choose desired color
and gobo. It will change ten colors and then change one gobo.
3.FAST/SLOW : When the LED is off, it is in FAST mode. The unit’s movement- Pan/Tilt &
Gobo/Color is sound activated. If the LED on, it is in SLOW mode, Pan/Tilt is sound activated
but Gobo/Color wheel are static, controlled by Next button.
In case of replacement of the lamp or maintenance, do not open the
fixture within 15 minutes until the unit cools down after switching off.

5.3 Universal DMX Controller
If you use a universal DMX controller to control the units, you have to set DMX address
from 1 to 512 channel so that the units can receive DMX signal.
Press the MENU button up to when the is shown on the display. PressingENTER button and the
display will blink. Use DOWN and UP button to change the DMX512 address. Once the address has been
selected, press and keep ENTER button pressed up to when the display stops blinking or storing automatically 8
seconds later. To go back to the functions without any change press the MENU button again. Please refer to
the following diagram
to address your DMX512 channel for the first 4 units.
5. How To Control The Unit
You can operate the unit in three ways:
1. By master/slave built-in preprogram function
2. By easy controller
3. By universal DMX controller
No need to turn the unit off when you change the DMX address, as new DMX address
setting will be effected at once. Every time you turn the unit on, it will show AE-5 on the display
and move all the motors to their ‘home’ position and you may hear some noises for about 20
seconds. After that the unit will be ready to receive DMX signal or run the built in programs.
5.1 Master/Slaver Built In Preprogrammed Function
By linking the units in master/slave connection, the first unit will control the other units to
give an automatic, sound activated, synchronized light show. This function is good when you
want an instant show. You have to set the first unit in master mode and select
(show 1) or (show 2) mode. Its DMX input jack will have nothing plugged into it, and Its
master LED will be constantly on and sound LED will flash to the music. The other units will
have to set in slave mode and select (normal) or (2 light show) mode,
Their DMX cables plugged into the DMX input jacks (daisy chain) and the slave led lights will
constantly on.
2-light show
In (slave mode), means the unit works normally and means 2-light
show. In order to create a great light show, you can set on the second unit to get
contrast movement to each other, even if you have two units only.
