Leviton DDS 6000 / 6000+ Satellite Dimmer Packs Manual

INTRODUCTION

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.

The total lamp wattage connected to each channel must not exceed the rating of each channel (see SPECIFICATIONS). For inductive loads, the total lamp volt-amperes plus the volt-amperes of any ballast or transformer must not exceed the rating of each channel.

NOTE: Some inductive type loads, such as transformers, ballasts, and motors with poor factor power may cause the dimmer to output DC type current. This may cause the load to draw excessive current and overheat, causing damage to the transformer, ballast or motor. For this reason, it is necessary to insure any inductive loads are fused individually for their respective normal operating current.

PERMANENT CONNECTION

The DDS 6000 is available as an optional DDS 6000 Plus - 20 terminal version. This version must be installed by qualified personnel.

AC Input

Conduit containing line conductors enters pack through one of the knockouts in the top end. The two 20A, 120V, 60Hz, 2 wire line circuits, A and B, are terminated to their respective terminals labeled Line and Line N. The terminals accept wire sizes 22-8 AWG CU and have a torque rating of 8 in-lbs. Line equipment grounding conductor, if a wire, terminates to the lug labeled GND. The ground lug accepts wire size 14-6 AWG CU and has a torque rating of 35 in-lbs. (14-10 AWG), 40 in-lbs. (8 AWG), and 45 in-lbs. (6 AWG).

AC Output

Conduit containing load conductors enters pack through one of the knockouts in the top end. The four 1200 W max., 120V, wire load circuits, 1 through 4, are terminated to their respective terminals labeled Load and Load N. Circuits 1 and 2 are supplied from input A, and circuits 3 and 4 from input B. The control power supply is also supplied by input A. Terminal rating are the same as indicated above for line terminals.

LED INDICATORS

The front panel indicator LEDs indicate the status of the relay.

• RED — Indicates the firing card is receiving DC power.
• GREEN — Steady indicates a multiplex control signal is being received.
• YELLOW — Indicates a respective dimmer channel is active and the LED indicates relative intensity.

CHANNEL FUSES

Each channel is protected by a fuse to help prevent overload and damage to the power control devices used in the dimmer. Be sure to replace the fuse with the same type of rating. Replacement with the wrong fuse is dangerous and will void your warranty.

NOTE: Lamps may sometimes cause a temporary "short-circuit" when the filament burns out and cause the fuse to blow. This is normal and protects the internal dimmer circuitry from damage.

MICROPLEX MULTIPLEX CONTROL WIRING

Microplex is the control protocol used on most Leviton-NSI lighting consoles. This system uses a single three conductor cable to transmit up to 128 channels of dimmer control. For short distances (50 feet or less) a standard microphone cable may be used to carry both the control signal and the DC power source for LevitonNSI control consoles. Longer distances may be accommodated with 18 gauge or better cable to reduce voltage losses of the power supply.

Female Microplex XRL Pin Configuration

Connect the Microplex control cable to either of the three pin XLR jacks. Since both jacks are wired in parallel, another control cable may be connected between the remaining jack and another dimmer pack. Many dimmer packs may be "daisy chained" together in this manner. Be sure to set the Channel Address DIP switch as required (see ADDRESSING).

ANALOG 0-10 VDC CONTROL WIRING

Each of the four channels of the DDS 6000 may be operated by an analog 0-10 VDC control voltage. This type of control will provide 0% intensity at 0 volts and 100% intensity at 10 volts. Any or all of the DDS 6000 dimmer channels may be operated in this manner simultaneously with any multiplex control input. Each dimmer will respond to the greater of any control inputs.

0-10V Input

The analog control input uses a standard 5 pin DIN plug which is available from most electronics supply houses. Connect each if the positive channel control wires to the desired dimmer channel input pins of the plug. Connect the common (ground) control wire to the pin indicated on the diagram. Consult the documentation of the analog control console or device you are using for the proper connections. The control input impedance is 4.7K ohms.

DMX512 MULTIPLEX CONTROL WIRING

DMX512 is the United States Institute of Theater Technology (USITT) standard for the digital control of dimmers. Leviton-NSI DDS dimmer products can be converted from Microplex to DMX512 digital multiplex with a simple kit available from your dealer.

Female DMX512 XLR Pin Configuration

DMX512 is the preferred type of control wiring when many dimmer channels are used, because of the high update rate and the resistance to interference. It is recommended in locations subject to electrical noise. DMX512 only requires 3 wires to transmit lighting levels for as many as 512 relay or dimmer channels. Most of the Leviton-NSI lighting control consoles can optionally use this interface.
Connect the DMX512 cable from the control console to the male input connector. Another cable may be connected from the female connector to the male connector of another pack. Many dimmer packs may be "daisy chained" or connected together in this manner.
Be sure to set the Channel Address DIP switch as required (see ADDRESSING).

AUTO LAMP TEST

Whenever DIP switch #8 is in the OFF (down) position and there is no multiplex signal detected, all channel outputs will come to full intensity. The automatic sequencing feature must be disabled for this Auto Lamp test to operate.

INTERNAL CONFIGURATION DIP SWITCH SELECTION

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.

ADDRESSING

When using any of the multiplex control systems, the DIP switches on the front panel of the DDS 6000 must be set to assign the desired dimmer channels. The switches control the dimmer channels in groups of four. See the following chart for settings.

When the automatic sequencing feature is operating, the DIP switch selects the operating sequence pattern and speed. See the section on INTERNAL CONFIGURATION DIP SWITCH SELECTION for details.
