Connect the device to the mains with the power plug. All devices must be powered directly off a grounded
switched circuit and cannot be run off a rheostat or dimmer circuit, even if the rheostat or dimmer channel
is used solely for 0 % to 100 % switching.
The installation has to be approved by an expert before the device is taken into service.

Use
Plug the power socket into the power supply (230 VAC, 50 Hz). This blinder is DMX-controlled via one channel.
DMX-512 Connection
When applicable, connect an XLR cable to the female XLR output of a controller (not incl.) and the other
side to the male XLR input of the device. Multiple devices can be linked through serial linking. The linking
cable should be a dual core, screened cable with XLR input and output connectors.
Maximum recommended serial data link distance is 500 meters (1640 ft). Maximum recommended number
of devices on a serial data link is 32 devices.
DMX chain with terminator:
A DMX terminator is recommended for installations where the DMX cable has
to run a long distance or used in an electrically noisy environment (e.g.
discos). The terminator prevents corruption of the digital control signal by
electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω
resistor between pins 2 and 3, which is then plugged into the XLR output
socket of the last device in the chain.
DMX Start Address Selection
All DMX-controlled devices need a digital start address so that the correct device responds to the signals.
This digital start address is the channel number from which the device starts to “listen” to the DMX
controller. The same starting address can be used for a whole group of devices or an individual address can
be set for every device.
When all devices have the same address, all the units will “listen” to the control signal on one particular
channel. In other words: changing the settings of one channel will affect all devices simultaneously. If you
set individual addresses, each device will “listen” to a separate channel number. Changing the settings of
one channel will only affect the device in question.
In case of the 1-channel mode, you will have to set the start address of the first unit to 1 (CH1), the second
to 2 (CH2), the third to 3 (CH3), and so on. The highest start address is 512.
DMX Address Setting
You can select the address by setting the DIP switches. DIP switch 10 always has to be ON.
The DMX start address of the fixture is defined by DIP switches 1-10. The encoding is binary: DIP switch 1 has
value 1, DIP switch 2 has value 2, DIP switch 3 has value 4, DIP switch 4 has value 8, etc.

For example: For start address 95, the settings are (for switches 1-10): 1111101000 (1 + 2 + 4 + 8 + 16 + 0
+ 64 = 95).

Cleaning and Maintenance
All screws should be tightened and free of corrosion.
The housing, the lenses, the mounting supports and the installation location (e.g. ceiling, suspension,
trussing) should not be deformed, modified or tampered with; e.g. do not drill extra holes in mounting
supports, do not change the location of the connections…
Mechanically moving parts must not show any signs of wear and tear.
The electric power supply cables must not show any damage. Have a qualified technician maintain the
device.
Disconnect the device from the mains prior to maintenance activities. Let the device cool down.
Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
Do not immerse the device in any liquid.
There are no user-serviceable parts, apart from the lamp (see “Installation”).
Contact your dealer for spare parts if necessary.
