DANGER!
Install the gobos with the device switched off only.
Unplug from mains before changing gobos!
Open the cover by loosening the fastening screw at the sides of the cover.
If you wish to use other forms and patterns as the standard-gobos, or if the gobos are to be
exchanged, remove the fixation ring with an appropriate tool. Remove the gobo and insert
the new gobo. Press the fixation-ring together and insert it in the front of the gobo.
CAUTION!
Never unscrew the screws of the rotating gobo as the ball bearing
will otherwise be opened!

3. Lamp
Because of its high internal pressure, there might be a risk that the Discharge lamp
would explode during operation. The lamp emits intense UV radiation which is harmful
to the eyes and skin. The high luminance of the arc can
cause severe damage to the retina if looks directly at
the lamp.
Discharge lamp : MSD 250/2 (MH-6616S)
HIT 150W (MH-666S)
1.Always switch off the main supply and never handle
the lamp or luminaries when is hot.
2.Do not touch the bulb with bare hands. If this happens,
clean the lamp with denatured alcohol and wipe it with
a lint free cloth before installation.
3.The lamp generates UV radiation. Never operate the
lamp without appropriate shielding.
4.When burning, the lamp operates at high pressure and
there is a slight risk of arc tube rupture. The risk
increases with age, temperature and improper handling
of the lamp. Do not use the lamp any longer than its
specified life.
5.Make sure the lamp is located in the center of the reflector for the
best spot. Adjust lamp position by screws A, B and C.
MH-666S
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. How To Control The Unit
You can operate the unit in three ways:
1. By master/slave built-in preprogram function
2. by universal DMX controller

12A
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 type 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/Slave Built-In Preprogrammed Function
You can select blackout mode in (yes blackout) or (no blackout)
mode while the unit is turned on. 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 select (show 1)
or (show 2) or (show 3) or (show 4) mode by easy controller. 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.
5.2 DMX Controller
Use 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 showing on the display. Pressing
ENTER 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.
13A
5.3 DMX512 Configuration
* MH-666S without Channel 8 – Focus.
NOTE: Shutter function is viable only when the value of channel 4 is between 0 and 18.

14A
5.4 DMX512 Connection
The DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.
1.If you use a controller with 5 pins DMX connector, you need to use a 5 to 3 pin adapter.
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 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 pins 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 (+)

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 connection of 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. Make sure the unit does not receive DMX signal.
2. 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.

16A
G. If The MH-6616S pan belt is broken
1. Turn off the main power.
2. Unscrew all the screws (A) and open the base-housing cover (B).
3. Unplug all the connect wires (C) that from the arm to PC board and igniter.
4. Unscrew the screws (D) that fix the bridge (E).
5. Unscrew the screws (F) that fix the axis gear (G).
6. Change a new belt (H) by going through all connecting wires that from the arm to base,
and through the bridge for correct position.
7. Set up the gear axis to the bridge and screwed it. Note: do not press the belt.
8. Put the belt around the axis gear and motor gear.
9. Plug all the connect wires (C) that form the arm to PC board and igniter.
10. Adjust the pan home position.
11.Screw the base-housing cover (B).
17A
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.
Clean with soft cloth using normal glass cleaning fluid.
yAlways dry the parts carefully.
yClean the external optics at least every 20 days. Clean the internal optics at least every
30/60 days.
