2. INTRODUCTION
Device description
The OMEGA, OMEGA+ and OMEGA W are a "Company NA" manufactured dimmers. The
Omega series dimmers are designed for controlling incandescent lamp brightness. The dimmers has
12 or 24 output channels. Its operating principle is based on triac ignition phase regulation.
The dimmer's output channel control is DMX-512 or manually from the front panel using the
“Test” or “Chase” modes. Operating the dimmer in “Test” mode, the output levels can be set with the
use of the graphic display independently of the DMX input. The “Test” mode allows for two output
signal set sizes –single channel (C) or group (G). Operating the dimmer in “Chase” mode replays a
prerecorded sequence independently of the DMX input. Six seperate sequences can run with control
of the sequence speed and direction, as well allowing the setting of backdrop levels. The settings
programmed in “Chase” mode operate only in this mode.
The OMEGA series dimmers front panel includes: display, operating controls, a digital
potentiometer, as well as 13 A or 16A circuit breakers for each individual regulated channel.
The OMEGA display graphically shows the DMX address set and input signal for 12
channels.

Installation Guide
These installation instructions is to explain the OMEGA system installation specifics.
However, this instruction is not a wiring regulation. Before the installation of the system need to
find a local state of wiring and installation options.
Installation instructions are divided into three parts:
- System Positioning specification,
- Installation guide,
- Appendix department, with other useful information.
Before the installation of the system read the first two chapters
Specification of system OMEGA dimmers
Setup
Dimmer OMEGA is designed for installation in the 19' rack or wallmount. Dimmer can be
installed on the stage or away from them, as well as for use in the touring. It is not advisable to
install the system in a public place where there is no possible access to the equipment without
disturbing the show. It is not advisable to place these devices close to the sound hardware.
Like any other dimmer, the OMEGA emit heat, so it must permit normal air circulation on
site. OMEGA system maximum operating temperature is +40 º C.
Power suply
OMEGA dimmer system must have 3 - Phase, 5 core supply the place of installation of the
following: 3 - Phase, 5 core phase to phase supply to the TN-S wiring system (connection
scheme L1 + L2 + L3 + N + E). Connection cable size depends on the dimmer fuse size
(cutting size) and it can be up to 35mm2 copper wire (see: the power cable characteristics).
Neutral cable should be large enough to lead the neutral current resulting from a phase shift as
a result of the dimmer is used part-intensity (typically up to 130% of the maximum possible
power phase). Strongly not recommended for smaller neutral cable, as it requires a dimmer
system for feeding.

Maximum fuse (switches) Dimensions:
Mono frame, with or without mains isolators
125A D-type auto fuse or equivalent (which
may be a fuse switch)
Double frame system without mains
isolators
250A D-type auto fuse or equivalent (which
may be a fuse switch)
Double frame system is equipped with
mains isolators
160A D-type auto fuse or equivalent (which
may be a fuse switch)
Power requirements
Wire size and load to the circuit wiring should comply with the rules. Dimmer fuse (switch)
size must comply with local cable overall dimensions (16A C-curve, or the 32A C-curve). If the
run size of one channel is up to 6mm2, the dimmer system is used to 16A C-curve fuse on one
channel, but if the run size is 10mm2, the system is used dimmers 32A C-curve fuse for each
channel.
Cooling
To provide cooling OMEGA and OMEGA + dimmers are equipped with two-high speed
internal fans, casing on the left side of unit corps. Fresh air is injected through holes in the left
side of corps, but warm air is discharged through holes located on the right side of corps.
Instalation
Preperation of the necessary components
Dimmer OMEGA is shipped with out a cable that is secured in place. In order to properly
carry out the installation of a dimmer prepare the section below details:
● Remove the wire connecting terminals by unscrewing two screws and at the same time
holding the DIN cable path. Then remove the wire connecting blocks.
● Disconnect the cable from the main arrivals cable connecting the frame (to move the cable to
the fuse side of 15mm, and move horizontally on 20mm)
● If the input cable is provided for detachable cable to the plate, remove it now.
Assembly of main cable
Mains power cable attach to a cable input terminal at the rear of the hull. The main power
cable assembly can be connected to a five-strand copper cable with conductor sizes up to
35mm2. To do so requires a straight blade screwdriver with a width of 4mm. Insert the screw-
blade main power cable assembly and press it. Now may be removed and a screwdriver with
both hands, insert the main power cable to connect the strands in the block hole. Make sure
the wires are placed correctly and outside the conductor connecting clamps are not visible
purified cable conductor parts.

5. Appendix
DMX-512 Protocol
DMX-512 protocol has 512 channels in one universs. Channels (adress) can be
committed in any way depending on the device. To operate equipment with DMX-512 protocol is
necessary one channel or multiple channels in a row depending on type of device. User sets up the
address of the equipment, which coincides with the light control panel installed. There are a lot of
equipment, which can be controlled via DMX-512 protocol, and they may have different
DMX channel number, so the start address must be selected in advance. DMX channels should
never overlap with each other. If the DMX channels are overlapping, equipment can run wrongly. If
you use the same type of equipment can impose a range of facilities with the
same starting address, only take into account that the installation will work exactly the
same and you will not be able to drive one of these machines separately.
Important:
EIA-485 standard requires that the device can be connected to one DMX univers with a
series circuit. In accordance with the provisions of the standard in one DMX series circuit can connect
only 32 devices. To be able to connect more than 32 devices in one DMX univers, you need to use the
DMX signal splitter vith the recovery function, which inputs and outputs are optically isolated.
Otherwise, the DMX-512 signal may be distorted and device management from the light control panel
will not be possible.
DMX Ddata cable
Use a Belden© 9841 or equivalent cable which meets the specifications for EIA RS-485
applications. Standard microphone cables cannot transmit DMX data reliably over long
distances. The cable will have the following characteristics:
2-conductor twisted pair plus a shield
Maximum capacitance between conductors –30 pF/ft.
Maximum capacitance between conductor and shield –55 pF/ft.
Maximum resistance of 20 ohms / 1000 ft.
Nominal impedance 100 –140 ohms
CABLE CONNECTORS
Cabling must have a male XLR connector on one end and a female XLR connector on the other
end.
DMX connector configuration

CAUTION Do not allow contact between the common and the fixture’s chassis
ground. Grounding the common can cause a ground loop, and your fixture may
perform erratically. Test cables with an ohm meter to verify correct polarity and
to make sure the pins are not grounded or shorted to the shield or each other.
3-PIN TO 5-PIN CONVERSION CHART
NOTE ! If you use a console with a 5 pin DMX output connector, you will need to use a
5 pin to 3 pin adapter. The chart below details a proper cable conversion:

Maintenance
To maintain optimum performance of equipment and reduce wear and tear, it is advisable
to clean them regularly. Frequency of usage and environmental exposure (dust, smoke, fluids), are
factors that contribute to equipment depreciation. It is recommended that equipment be cleaned at
least twice a year. Equipment overlap with dust may cause equipment overheating in case of
insufficient aeration. This leads to reduced equipment life and increase the use of mechanical
equipment wear. Before cleaning, disconnect it from power. Use a vacuum or air compressor and a
soft brush to remove dust from outer parts of the set, as well as internal components of the equipment.
Cleaning frequency depends on the environment in which the facility is operating: damp, smoky or
particularly dirty surroundings can cause greater accumulation of dirt.
