INTRODUCTION
Thank you for your decision to purchase a Leviton-NSI product.
The Leviton-NSI DDS 6000 represents a key part of a state of the art, integrated lighting control system.
These dimmers may operate in a “stand alone” mode for automated lighting of displays or may be combined
with a Leviton-NSI memory lighting console for total lighting control.
The DDS 6000 provides four channels of 1200 watts each. This dimmer is designed for portable or permanent
use for entertainment or display lighting. Several DDS dimmer packs may be combined for more channels of
lighting.
SPECIFICATIONS
MOUNTING
The Leviton-NSI DDS 6000 dimmer pack is designed to be mounted vertically. Each dimmer pack is provided
with two mounting flanges or ears designed for securing to the center of truss or attaching to other vertical
surfaces.
Since the DDS 6000 depends upon convection cooling, room air flow must be insured. Keep the air vents
located on front and each side of the dimmer pack clear of dust or any obstructions. In order for unit to cool
properly the control receptacles must be oriented towards the floor.
If several units are to be operated in a small enclosed room, adequate ventilation must be provided to
prevent the room temperature from exceeding 100 degrees Fahrenheit.
AC POWER CABLE
This is the main power cord(s) for your dimmer pack which ultimately carries all of the AC power consumed
by lights connected to the dimmer pack. The DDS 6000 with the NEMA 5-15 plug is limited to 1800 Watts
max., while the unit with the NEMA 5-20 plug will support 2400 Watts. The DDS 6000 Plus includes two
cords, one per each two channels, which doubles the maximum capacity. The power cord(s) must be connected
to a power source capable of supplying the total power drawn by the lights. (See SPECIFICATIONS for
details on maximum power capability).
AC OUTPUT RECEPTACLES
The DDS 6000 has two AC receptacles for each channel. These receptacles provide power to the lamps in your
lighting system. The amount of power supplied to these outlets controls the intensity of the lamps connected.
Most 120VAC lamps and fixtures, and some transformer type low-voltage fixtures may be connected to these
outlets.

1200 Watts per channel.

DDS 6000-20: 120 VAC, 2400 Watts Max. (One power source)
DDS 6000 Plus -15: 120 VAC, 3600 Watts Max. (Two power sources)
DDS 6000 Plus -15: 240 VAC, 4800 Watts Max. (Two power sources)
DDS 6000 Plus -20: 120 VAC, 4800 Watts Max. (Two power sources)
Dimmer Control System:
Microprocessor digital phase control dimming or zero-crossing relay mode.
Load Filtering:
400 Micro-Second Rise Time.
Control Input Types:
0-10 VDC each channel on a 5-pin DIN connector.

2 NEMA 5-15 outlet per channel.
Screw terminals optional.
Cooling System:
Passive internal aluminum heatsinks.
Load Type:
AC lighting (tungsten) loads only.
Enclosure Type:
For indoor use only (Utilizer Dans Un Endroit A L'Abri).
Ambient Temperature:
100 degrees maximum.

INTERNAL CONFIGURATION DIP SWITCH SELECTION
Caution: The following procedures should be performed by qualified personnel only.
Remove all power and remove the cover of the dimmer pack. Locate and change configuration DIP switch
settings on the firing card as indicated in the following section.
Softstart
The Softstart mode of operation forces at least a 1/10th second delay between the output being full OFF to
the output being full ON to allow a more gradual warming of the lamp filaments. Thermal shock and inrush
currents are reduced thereby increasing lamp life. Softstart should not be used when quick dimmer response
is desired, such as chasing.
To activate Softstart, turn OFF switch number one (1) on the configuration DIP switch on the firing card.
Moving this switch to ON will deactivate Softstart.
NOTE: The channels of the DDS 6000 configured for NON DIM operation will not be affected by softstart.
NON DIM Channels (Relay Mode)
Any of the channels of the DDS 6000 may be configured as NON DIM channels. This will cause the output of
the channel to go to full ON whenever the input signal is over 15%. When the input signal drops to less than
10%, the channel output goes to full OFF. This is the equivalent of a zero-crossing solid state relay.
To configure a channel for NON DIM operation, simply move the respective switches on the configuration DIP
switch to the OFF position on the firing cards as indicated below. Moving the switch to ON will restore dimming
operation.
AUTO SEQUENCING MODE
The DDS 6000 dimmers can be configured to perform stand alone Automatic Sequencing in place of Auto
Lamp Test. This is useful for lighting displays and show windows. The four channels will automatically fade
from one to another in a preprogrammed pattern and time selected by the front panel DIP switch whenever DIP
switch #8 is up and no multiplex signal is detected. The analog control input will continue to operate while the
dimmer is sequencing.
To enable Automatic Sequencing Mode move the switch on the internal configuration DIP switch #2 to OFF.
Front Panel DIP switch sequence settings (not internal DIP switch):
DIP switch #7 ON causes all above sequences to ping-pong.
INSTALLATION AND OPERATION TIPS
Care should always be taken to:
1)
Keep all AC wiring away from control wiring.
2)
We also recommend power up and performance checks be done one unit at a time. This can be a real
time saver should problems arise thus eliminating unnecessary isolation techniques to resolve problems.
