• Overhead mounting requires extensive experience: calculating work load limits, determining the installation
material to be used... Have the material and the device itself checked regularly. Do not attempt to install the
device yourself if you lack these qualifications as improper installation may result in injuries.
• Adjust the desired inclination angle via the mounting bracket and tighten the bracket screws.
• Make sure there is no flammable material within a 0.5m radius of the device.
• Have a qualified electrician carry out the electric connection.
• Connect the device to the mains with the power plug. Don't connect it to a dimming pack.
• The installation has to be approved by an expert before the device is taken into service.
5. Use
Switch the device on and off by means of the power plug. Do not operate the device continuously.
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 "listens" to the digital commands from the DMX controller.
The start address/channel number is set by means of the DIP switches located at the back of the device.
You can set the same start address for a whole group of devices or enter an individual one for every device.
When using one single 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 different addresses,
each device will "listen" to a separate channel number. Changing the settings of one channel will only affect the
device in question.
In the case of the VDP250SC4EHJ, a 4 channel device, you will have to set the start address of the first unit to 1, the
second unit to 5 (1 + 4), the third unit to 9 (5 + 4), and so on. The DMX start address is defined by the first 9 DIP
switches. The encoding is binary: DIP switch 1 has value 1, switch 2 has value 2, switch 3 is 4, switch 4 is 8, etc.
For example, if the start address were 95, the settings would be 111110100 (1+2+4+8+16+0+64+0+0=95).
The LED next to the DIP switches indicates the status of the DMX signal: if it's flashing there's a DMX signal; if it's off
there's no DMX signal.
Channel configuration
CHANNEL 1: 7 colours + white + shutter
CHANNEL 2: 6 gobos + white
CHANNEL 3: pan
CHANNEL 4: tilt
It is possible to link multiple units for synchronous operation by means of the enclosed DMX cable.
6. Cleaning and Maintenance
1. All screws should be tightened and free of corrosion.
2. 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...
3. Mechanically moving parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician maintain the device.
5. Disconnect the device from the mains prior to maintenance activities.
6. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
7. There are no user-serviceable parts, apart from the lamp and the fuse (see "Installation").
8. Contact your dealer for spare parts if necessary.
