To insert the lamp MSD/HSD 200 GY-9.5, MSD/HSD 250 GY-9.5 or MSD 250/2 GY-9.5 open the top cover
of the projector head (see the drawing) by loosening the screws on the top cover.
Then open the small lamp cover by loosening the fastening screws (see the drawing).
If changing the lamp, remove the old lamp from the socket. Insert the lamp to the socket.
Do not install a lamp with a higher wattage! A lamp like this generates temperatures the device is not
designed for.
Damages caused by non-observance are not subject to warranty. Please follow the lamp manufacturer‘s
notes!
Do not touch the glass-bulb bare-handed during the installation! Make sure that the lamp is installed tightly
into the lampholder system.
Adjust the optimal distance 1-1.5 mm from the lens by turning the screw "A" (see the drawings "Lamp
adjustment" below).
Then close the small lamp cover by tighten the fastening screws again.
Reclose the top cover of the head and tighten the Phillips screws.
Before striking the lamp, reset the "LAti" counter and the "LASt" counter in the main menu of the Control
Board, by pressing the "Up" and "Down" buttons in one time and then confirming with the Enter-button.

Lamp adjustment
CORRECT
Optimum distance 1-1.5 mm
INCORRECT
Keep optimum distance to the lens!
Rearpanel Moving-Head
Screw "B"
Screw "A"
The MH-680 lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may
improve light performance.
Strike the lamp and focus the light on a flat surface (wall). As the optimum distance of lamp from lens was
adjusted during the installing or changing the lamp (by turning the screw "A"), it is necessary to adjust only
the second position by turning the screw "B", in order to center the hot-spot (the brightest part of the beam).
If the Hot Spot seems to be too bright, you can lower its intensity by moving the lamp closer to the reflector.
Do so by turning srew "A" until the light is evenly distributed.
If the light on the edge seems to be brighter as in the center, the lamp is too close at the reflector. In this
case, you need to move the lamp away from the reflector until the light is evenly distributed and the beam
appears bright enough.

Rigging
DANGER TO LIFE!
Please consider the EN 60598-2-17 and the respective national norms during the
installation! The installation must only be carried out by an authorized dealer!
The installation of the projector has to be built and constructed in a way that it can hold 10 times the weight
for 1 hour without any harming deformation.
The installation must always be secured with a secondary safety attachment, e.g. an appropriate catch net.
This secondary safety attachment must be constructed in a way that no part of the installation can fall down if
the main attachment fails.
When rigging, derigging or servicing the fixture staying in the area below the installation place, on bridges,
under high working places and other endangered areas is forbidden.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert before taking into operation for the first time and after changes before taking into operation another
time.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert after every four year in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are approved by a
skilled person once a year.
Procedure:
The projector should be installed outside areas where persons may walk by or be seated.
IMPORTANT! OVERHEAD RIGGING REQUIRES EXTENSIVE EXPERIENCE, including (but not limited to)
calculating working load limits, installation material being used, and periodic safety inspection of all
installation material and the projector. If you lack these qualifications, do not attempt the installation yourself,
but instead use a professional structural rigger. Improper installation can result in bodily injury and.or
damage to property.
The projector has to be installed out of the reach of people.
If the projector shall be lowered from the ceiling or high joists, professional trussing systems have to be used.
The projector must never be fixed swinging freely in the room.
Caution: Projectors may cause severe injuries when crashing down! If you have doubts concerning the
safety of a possible installation, do NOT install the projector!
Before rigging make sure that the installation area can hold a minimum point load of 10 times the projector's
weight.
DANGER OF FIRE!
When installing the device, make sure there is no highly-inflammable
material (decoration articles, etc.) within a distance of min. 0.5 m.
CAUTION!
Use 2 appropriate clamps to rig the fixture on the truss.
Follow the instructions mentioned at the bottom of the base.
Make sure that the device is fixed properly! Ensure that
the structure (truss) to which you are attaching the fixtures is secure.

13
The Moving-Head can be placed directly on
the stage floor or rigged in any orientation
on a truss without altering its operation
characteristics (see the drawing).
The fixture’s base enables to be mounted in
two ways: via the Omega-holders or via the
adapter plate. Use the clamps with screws
M12.
For overhead use, always install a safety-
rope that can hold at least 12 times the
weight of the fixture. You must only use
safety-ropes with screw-on carabines.

Connection with the mains
Connect the device to the mains with the power-plug.
The occupation of the connection-cables is as follows:
Cable Pin International
Brown Live L
Blue Neutral N
Yellow/Green Earth
The earth has to be connected!
In general, lighting effects should not be connected to dimming-packs.
DANGER TO LIFE!
Before taking into operation for the first time, the installation has to be approved by an expert!
DMX-512 connection / connection between fixtures
Controller
connection
Master/Slave
connection
The wires must not come into contact with each other, otherwise
the fixtures will not work at all, or will not work properly.
Only use a stereo shielded cable and 3-pin XLR-plugs and connectors in order to connect the controller with
the fixture or one fixture with another.
Occupation of the XLR-connection:

16
If you are using the recommended FUTURELIGHT-controllers, you can connect the DMX-output of the
controller directly with the DMX-input of the first fixture in the DMX-chain. If you wish to connect DMX-
controllers with other XLR-outputs, you need to use adapter-cables.
Building a serial DMX-chain:
Connect the DMX-output of the first fixture in the DMX-chain with the DMX-input of the next fixture. Always
connect one output with the input of the next fixture until all fixtures are connected.
Caution: At the last fixture, the DMX-cable has to be terminated with a terminator. Solder a 120 Ωresistor
between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the DMX-output of the last fixture.
Master/Slave-operation
The master/slave-operation enables that several devices can be synchronized and controlled by one master-
device.
On the rear panel of the MH-680 you can find an XLR-jack (DMX Out) and an XLR-plug (DMX In), which can
be used for connecting several devices.
Choose the device which is to control the effects. This device then works as master-device and controls all
other slave-devices, which are to be connected to the master-device via a balanced microphone lead.
Connect the DMX OUT-jack with the DMX IN-plug of the next device.
Caution: At the master-device and at the last slave-device, the DMX-cable has to be terminated with a
terminator. Solder a 120 Ωresistor between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the
DMX-output.

Function of the control channels - 8 bit protocol:
DMX-controlled operation
You can control the projectors individually via your DMX-controller. Every DMX-channel has a different
occupation with different features. In order to call up the different features, you first have to ignite the lamp
(control channel 6, DMX-value 128-139).
Addressing
The Control Board on the front side of the base allows you to assign the DMX fixture address, which is
defined as the first channel from which the MH-680 will respond to the controller.
If you set, for example, the address to channel 5, the MH-680 will use the channel 5 to 20 for control.
Please, be sure that you don’t have any overlapping channels in order to control each MH-680 correctly and
independently from any other fixture on the DMX data link.
If two, three or more MH-680 are addressed similarly, they will work similarly.
For address setting, please refer to the instructions under "Addressing" (menu "A001").
Controlling:
After having addressed all MH-680, you may now start operating these via your lighting controller.
Note:
After switching on, the MH-680 will automatically detect whether DMX 512 data is received or not. If there is
no data received at the DMX-input, the display will start to flash "A001" with actually set address.
This situation can occurr if:
- the 3 PIN XLR plug (cable with DMX signal from controller) is not connected with the input of the MH-680.
- the controller is switched off or defective, if the cable or connector is defective or the signal wires are swap
in the input connector.
Note:
It’s necessary to insert the XLR termination plug (with 120 Ohm) in the last lighting in the link in order to
ensure proper transmission on the DMX data link.
Remotely controllable functions
Lamp
The MH-680 is to be operated with a MSD/HSD 200, MSD/HSD 250 or MSD 250/2 GY-9.5 lamp.
A relay inside of the MH-680 allows you to switch on and off the lamp via the Control Board on the top side
or via your controller without affecting the rest of the lighting.
For switching on and off the lamp via the Control Board, please refer to the instructions under "Switching
On/Off the lamp" (menu "LAMP")
Note :
It is also important to note that the discharge lamp is a cold restrike type, which means that it has to be cold
before re-striking. For this reason, you have to wait 5 minutes (max. speed of fan must be adjusted) after
having switched off the lamp before you can switch it back on again. If you try to switch on the lamp within 5
minutes after having switched it off, the MH-680 will store this information and automatically ignite the lamp
when the 5 minutes period has expired. The message "HEAt" will appear on the control board display at the
back side of the MH-680. If the ignition of the lamp is seven times unsuccessful, on the display will appear
"LA.Er", meaning that the lamp could be damaged or even missed, or there could be a failure on the ignitor
or ballast.
