HQ-Power VDP7525BL Manual Del Usuario página 6

• The VDP7525BL is designed to be mounted on the floor or on a gantry. It is equipped with an
interlocking mechanism [3] which makes it possible to physically connect multiple VDP7525BL
blinders. Note: to use the interlocking mechanism [3], the bracket nuts [2] and bracket [1] must
be removed. Use an appropriate hex-key to engage/disengage the lock.
• Have the device installed by a qualified person, respecting EN 60598-2-17 and all other applicable
norms.
• The carrying construction must be able to support 10 times the weight of the device for 1 hour
without deforming.
• The installation must always be secured with a secondary attachment e.g. a safety cable when
mounted overhead.
• Never stand directly below the device when it is being mounted, removed or serviced. Have a
qualified technician check the device once a year and once before you bring it into service.
• Install the device in a location with few passers-by that is inaccessible to unauthorised persons.
• Adjust the desired inclination angle via the mounting bracket and tighten the bracket screws.
• Make sure there is no flammable material within a 0.5 m radius of the device.
• Have a qualified electrician carry out the electric connection. Note that only one type of DMX
cabling can be used (either 3 pins or 5 pins). Make sure the cabling is not stressed and doesn't run
over sharp edges.
• Connect the device to the mains with the included Powercon power cable. Do not connect it to a
dimming pack.
• The installation has to be approved by an expert before the device is taken into service.
Connection to the AC Power Supply
The AC socket providing power to the VDP7525BL must be properly and
separately earthed. Do not use any other AC cords than the one provided or any
other AC cord not authorized by the manufacturer.
• Simply insert the supplied AC power cord into the power input [4] and insert the power plug into a
suitable wall outlet.
DMX Connection
Refer to the illustrations on page 2 of this manual.
• Connect an XLR cable to the female 3-pin or 5-pin XLR output of a controller (not incl.) and the
other side to the male 3-pin or 5-pin XLR input [7] of the VDP7525BL.
• Multiple VDP7525BLs can be linked through serial linking. The linking cable should be a dual
core, screened cable with XLR input and output connectors. The max. number of linked devices
on a DMX link depends on the used channel mode (see below):
4CH = 128 devices
o
9CH = 56 devices
o
25CH = 20 devices
o
29CH = 17 devices
o
Note: Provide only 1 DMX input signal to each device, use only 1 DMX output. Do not mix 3 pins
and 5 pins DMX cabling e.g. when the DMX controller is connected to the 3 pins input
connector, the 3 pins output connector must also be used.
• A DMX terminator is recommended for installations where the DMX cable has to run a long
distance or is 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.
7. Operation
• The VDP7525BL can work in 4 DMX-modes: 4 channel, 9 channel, 25 channel and 29 channel.
• Press the mode button [9] to select the desired mode.
• Press the UP- [10] or DOWN- [11] buttons to set the appropriate DMX-address.
Notes:
• 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.
