For address setting follow this procedure:
1. Switch on the MH-660 and wait until the fixture reset has finished ("rSt" is flashing at the display).
2. Press the [Mode] key in order to access the main menu. Browse through the menu by pressing the [Up]
and [Down] keys until the display shows "A001". Confirm by pressing [Enter] key and the letter "A" will flash.
3. Use the [Up] and [Down] keys to select the desired address.
4. Confirm by pressing [Enter] or [Mode] to cancel.
Controlling:
After having addressed all MH-660 , you may now start operating these via your lighting controller.
Note:
After switching on, the MH-660 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-660
- 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.
6. Remotely controllable functions
6.1 Lamp
The MH-660 is to be operated with a MSD 250 W/200 W lamp.
A relay inside of the MH-660 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.
6.2 Switching on and off the lamp via the Control Board
1. Switch on the MH-660 and wait until the fixture reset has finished.
2. Press the [Mode] key in order to access the main menu. Browse through the menu by pressing the [Up] and
[Down] keys until the display shows "LAMP". Confirm by pressing [Enter] key.
3. Use the [Up] and [Down] keys to select "On" for switching on the lamp and "Off" for switch off the lamp and
press [Enter] to confirm or [Mode] to cancel.
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-660 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-660.
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.
6.3 Colour-wheel
The MH-660 features a colour-wheel with 12 color positions - 11 of these with dichroic colors and the last one
open. The wheel can be positioned between two adjacent colors in any position. It is also possible to rotate the
color-wheel continuously at different speeds - the so-called "Rainbow effect“ is created.
6.4 Rotating gobo-wheel
The rotating gobo-wheel includes 4 metal gobos, 1 glass gobo and 1 multicolor dichroic gobo rotating in both
directions, indexable, rotating gobo wheel cont. rotation slow to fast. The multicolor dichroic gobo (containing
C,M,Y colors) can be combined with the color-wheel especially with cyan, magenta and yellow colours in order to
obtain several different multicolor beams. The gobos have an outside diameter of 27 mm and an image diameter of
23 mm.
6.5 3-facet rotating prism
3-facet prism rotating in both directions at different speeds.
6.6 Focus
Motorized focus enables the beam to be focused anywhere on stage.
