4. Installation of fixture
Fixture can be placed horizontally, inclined or upside down. Pay attention to the
installation method when hanging diagonally or upside down.
As shown in Figure 2, before positioning the Fixture, the stability of the
installation site shall be ensured. During the reverse hanging installation, it is
necessary to ensure that the lamp does not fall off the support frame. It is

necessary to use a safety rope to pass through the support frame and the lamp
handle for auxiliary hanging to ensure safety and prevent the lamp from falling
and sliding.
During the installation and commissioning of fixtures, pedestrians are not
allowed to pass under them. Regularly check whether the safety ropes are worn
and whether the hook screws are loose.
Our company will not bear any responsibility for all consequences arising from
falling fixtures due to unstable hanging installation.

The schematic diagram of the fixture panel is shown in Figure 3. The title above shows the
lamp name, and the status bar below shows the signal, bulb status, and fault of the
current lamp ("ERR" is displayed when the fault information is not viewed, otherwise
"NOR" is displayed).
This fixture supports the DMX/RDM protocol. When the lamp is searched by the RDM host,
three letters "RDM" will appear on the panel, indicating that the lamp is normally
enumerated.
The display and operation are similar to "Android operating system". Click the
corresponding item with your fingertip or blunt object to operate
2. Menu operation
1. Select the menu item
The left area is the TFT display area and the touch area. Click the panel content with your
finger or blunt hardware to complete parameter settings or check the status.
2. Parameter value input
Setting value: You can directly pull the slider to quickly set the required value, or click the
"Up" or "Down" button on the right to precisely set the required value or use auxiliary
input to set.

Application value: When the data is set by pressing the "Up" or "Down" button, and then
press the "Apply" button at the bottom left corner, the value will be sent to the lamp
immediately, but the value is not saved.
Save the value: at any time, click the "OK" button at the bottom right corner to save the
current value to the internal memory, and the saved value will be applied to the lamp
when it is turned on next time.
3. Function Menu Description
1. Set DMX address code
The menu setting of lamps optimizes the address setting, and several operations for
setting address codes are as follows:
Select "Previous" or "Next", the lamp will automatically calculate the address code of the
next or previous set according to the current address code and channel data, which can
be quickly set;
Click the address code value to enter the value editing window, where you can set any
valid address code. The fixture automatically obtains the current channel number of the
lamp, and automatically filters the address code (512 - current channel number) that
cannot be used.
The fixture supports RDM protocol, and the lamp address code can be set remotely
through RDM.
Two buttons are provided:

Channel mode: different channel modes can be selected circularly;
fixture reset: reset all motors.
2. Set fixture working mode
The fixture supports four operation modes (DMX mode, self-propelled mode, voice
control mode and scene mode)
3. Panel display setting
Fixture support Chinese English bilingual, upside down display

Chapter 4 Common Faults and Precautions
1. Common fault handling
The fixture contains microcomputer circuit board, high-voltage power supply and
other professional components. For your safety and product life, no professionals
are not allowed to dismantle the fixture and related accessories without
authorization.
1. The bulb does not light up (except for LED light source)
Possible causes: The bulb is not completely cooled, or the bulb has reached its
service life. The treatment is as follows:
Due to abnormal operation, the bulb is not completely cooled, so the lamp body
should be allowed to cool for more than 10 minutes to fully restore its interior to
normal state, and then start the power supply again;
Check whether the bulb has reached its service life, and replace it with a new one;
Check whether the circuit between the bulb and the lamp lighter leaks, falls off or
has poor contact;
Replace with a new lamp lighter.
2. The beam appears dim

Possible causes: The bulb has been used for a long time or the light path is not
clean. The treatment is as follows:
Check whether the bulb has reached its service life, and replace it with a new one;
Check whether the optical components or bulbs are clean and whether there is
dust on the bulbs and other optical components. Clean and maintain the bulbs
and components in the lamps regularly.
3. Blurred pattern projection
Check whether the electronic focusing channel value is suitable for the current
projection distance.
4. The fixture works intermittently
Possible causes: the internal circuit enters the protection state, and the treatment
is as follows:
Check whether the fan operates normally or becomes dirty, causing the
temperature inside the lamp to rise;
Check whether the internal temperature control switch is closed;
Check whether the bulb has reached its service life and replace it with a new one.
5. The lamp does not accept the control of the console after normal reset
Possible causes: signal line fault or abnormal lamp parameter setting. The
handling is as follows:
Check the starting address code and the connection of the DMX signal line
(whether the signal line cable is in good condition and whether the connection of
the CORNON head is loose);

Add signal amplifier and 120 ohm terminal resistor;
6. The fixture cannot be started
Possible causes: the power line is poor, and the treatment is as follows:
Check whether the fuse on the power input socket is fused, and replace the fuse;
Poor line contact caused by vibration of lamps during long-distance transportation
Check the input power supply, computer board and other plug-in devices.
2. Precautions
Check whether the local power supply meets the rated voltage requirements of the
product, and whether the leakage protector, over-current protector, etc. meet the
load requirements;
Do not use the power cord with damaged insulation layer, and do not lap the power
cord onto other wires;
The fixtures are cooled by strong wind, which is easy to accumulate dust, so they
must be cleaned once a month, especially the cooling air outlet, otherwise the lamps
will be blocked by dust, resulting in poor heat dissipation and abnormal fixtures.
When installing lamps and lanterns, the fixing screws must be fastened, safety cables
should be added, and regular inspection should be carried out;
During the installation and positioning of the lamp, the minimum distance between
any point on the fixture surface and any combustible or explosive substance is 10
meters, and the distance from the illuminant is 2.5 meters. Please do not directly
install the fixture on the surface of combustible substances;
It is recommended that the continuous working time of the fixture should not exceed

10 hours, and the interval between the continuous starting of the fixture should not
be less than 10 minutes, otherwise it will not be triggered normally due to the
overheat protection of the bulb;
The closing time of switching valve shall not exceed 5 minutes. If it is necessary to
turn off the light for a long time, the control console (lamp control channel) shall be
used to turn off the fixture;
3. Precautions for using RDM
RDM is an extended version of DMX512-A protocol. It is a Remote Device Management
protocol. The traditional DMX512 protocol communication is one-way
communication. The protocol is based on the RS-485 bus. RS-485 is a time-sharing
multipoint and half duplex protocol. Only one port is allowed to output for the host
at a time. Therefore, the following points should be noted when using RDM:
The console or host equipment that supports RDM protocol hosts shall be used;
To use a two-way signal amplifier, the traditional one-way signal amplifier is not
suitable for RDM protocol, because the RMD protocol requires feedback data, and the
use of a one-way amplifier will block the returned data, resulting in no lamp search;
All fixtures must be set to DMX mode to ensure that there is only one host on the
signal line;
A 120ohm impedance matching resistor must be inserted between terminals 2 and 3
of the terminal plug. When the signal line is relatively long, reducing the signal
reflection will make the differential signal more stable, which is conducive to the
quality of communication;

When the fixture is controlled by DMX, but the RDM cannot search the fixture, check
the signal amplifier first, and then check whether there is a poor contact between the
2 and 3 lines of the signal line.
