Connection with the mains
Connect the device to the mains with the enclosed power supply cable.
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!
If the device will be directly connected with the local power supply network, a disconnection switch with a
minimum opening of 3 mm at every pole has to be included in the permanent electrical installation.
The device must only be connected with an electric installation carried out in compliance with the IEC-
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum
fault current of 30 mA.
Lighting effects must not be connected to dimming-packs.
The device is equipped with a lockable power input connector. Plug in the power cord and turn it to the right
until it locks. Plug the power cord into a grounded electrical outlet that matches the rated voltage of the
machine.
On the rear panel, there is a socket (Power Out). Connect the output with the mains input of the next fixture
until all fixtures are connected.
Please note:
A maximum of 8 devices may be linked together. After every 8 devices, the fixtures must have
a renewed connection with the power mains.
OPERATION
With the power switch, you can switch the device on and off.
After you connected the effect to the mains, the DMH-90 starts running. During the reset, the motors are
trimmed and the device is ready for use afterwards.
Stand Alone operation
In the Stand Alone mode, the DMH-90 can be used without controller.
Disconnect the DMH-90 from the controller and call the internal program.
Please refer to the instructions under Control Board.
DMX-controlled operation
You can control the projectors individually via your DMX-controller. Every DMX-channel has a different
occupation with different features. The individual channels and their features are listed under DMX-protocol.
Addressing
The Control Board allows you to assign the DMX starting address, which is defined as the first channel from
which the DMH-90 will respond to the controller.
If you set, for example, the address to channel 20, the DMH-90 will use the channel 20 to 38 for control.
Please, be sure that you don’t have any overlapping channels in order to control each DMH-90 correctly and
independently from any other fixture on the DMX-chain.
If several DMH-90 are addressed similarly, they will work synchronically.
Press the Up/Down-buttons for setting the desired starting address. Now you can start operating the DMH-
90 via your lighting controller.
