1 Introduction
The Leprecon LDS-610 dimmer is designed to be a reliable and serviceable installation dimmer.
The form factor of the LDS-610 allows dimmers to be installed in facilities that may not have
room for conventional systems.
With the menu-based interface, the dimmer can be configured for different applications,
including stand-alone use without a controller. Default values can be restored at any time,
clearing the internal memory back to the standard values.
The LDS-610 dimmer is designed for use with conventional incandescent fixtures. Highly
inductive loads, such as low voltage devices using a step-down transformer, may require an
additional load to be connected to the same circuit to operate properly.
Florescent fixtures with two wire dimmable ballasts can be used with the LDS-610 dimmer. For
operating florescent fixtures, see the section regarding Front Panel Controls.
2 Models offered
2.1 The Leprecon LDS-610 dimmer is available in several configurations.
Three types of load connectors are available for connecting dimmer circuits to fixtures, 20 amp
Stage Pin, NEMA 5-15 duplex outlets, or L5-20 Twist receptacles.
Any of these models is available with two auxiliary power circuits, each with a capacity of 10
amps. This provides a convenient power source for color changers or other powered
accessories. Auxiliary power is provided by NEMA 5-15 duplex outlets regardless of load
connector type.
2.2 Optional Wireless DMX
Leprecon LDS-610 is available with wireless DMX capability. This system has been developed
by Wireless Solutions and offers increased flexibility and convenience for setting up a DMX
system. Leprecon W-DMX dimmers will be compatible with other W-DMX equipment that uses
components from Wireless Systems.
When a LDS-610 is used in a wireless system, it converts the wireless signal to a conventional
DMX signal. The DMX output of the wireless dimmer can be used to drive other conventional
DMX receivers.
So, in a wireless system, one dimmer can be used to receive the signal from the transmitter
and connect with DMX cable to up to 32 other standard DMX devices.
W-DMX dimmers are identical to the standard models, with these additions:
●
Internal receiver card and power supply
●
External antenna
●
Switch and LED indicator for setting the communication link
3
Background Information
The W-DMX system uses a 2.4 GHz radio signal to transmit DMX data. Spread-spectrum
transmission (AFHSS) technology prevents interference with the DMX signal from other radio
devices.
Range for the W-DMX is approximately 2300 feet using the standard antenna with a clear lineof-sight. The signal will penetrate walls and other barriers, but the signal level will be reduced.
Human bodies will block the signal, so it is best to locate the transmitter and receiver above
audience areas.
W-DMX Link
The LDS-610 dimmer is designed to receive data from any of the W-DMX transmitters. A
system is complete when the receiver is 'linked' to a specific transmitter. Establishing the 'link'
allows many receivers to be controlled by a single transmitter, and also allows multiple
transmitters to be used in the same area, each controlling specific receivers.
The LDS-610 dimmer center panel has two controls for setting up the W-DMX link.
The LED located on the center panel of the dimmer shows the status of the wireless link.
OFF – Dimmer is not linked to any transmitter. DMX cable input can be used.
ON – Dimmer is linked to a transmitter and receiving DMX data.
ON-short Blink off – Dimmer is linked to a transmitter but no data is being received.
ON/OFF flash – Dimmer was linked but connection was lost.
The push button switch below the LED (black) is used to unlink the receiver from the
transmitter. To do this, press the switch and hold it down for four seconds. The LED will turn off,
indicating that the link has been broken.
4
To establish a link to a specific transmitter:
1) Unlink the dimmer by pressing and holding the switch as described above. Verify that
the LED is off.
2) Press the function switch on the TRANSMITTER for one second. The dimmer LED
should light to indicate that it is now linked to the transmitter.
To unlink ALL dimmers from the transmitter:
1) Press and hold the function switch on the TRANSMITTER for four seconds. The
status LED's of all dimmers previously linked to that transmitter will turn off.
More inf can be found in the manual for the specific W-DMX transmitter that you have in the
system.
3 Specifications
3.1 Dimensions
The LDS-610 is built on an extruded aluminum chassis. The dimensions for the dimmer are as
follows:
Length 76.2 inches
Width 5.75 inches
Depth 3.8 inches
Weight: 36 lbs
3.2 Power Connection
Unless otherwise indicated, your LDS-610 dimmer is designed for connection to standard US
power systems, 120 VAC 60 Hz. Lamp connections must be 120 V devices only. Line voltages
over 135 VAC will trigger the over-voltage protection circuit and shut off the dimmer pack.

3.3 Ambient Temperature
The LDS-610 dimmer is designed for use in a cool, ventilated area. Ambient air temperature
must be less than 40 degrees Celsius, or about 104 degrees Fahrenheit. Temperatures in
excess of this limit will cause an over temperature shutdown, indicated by 'Er01' on the display.
3.4 Power Capacity
The LDS-610 dimmer is a six circuit dimmer. Each circuit has a capacity of 1200 watts, and is
protected with a thermal-magnetic circuit breaker.
LDS models with Aux power have an additional two non-dimmed convenience circuits. These
can be used to power color changers, DMX buffers, or any other type of line-operated
equipment. Each of the two duplex convenience outlets has a maximum load of 1200 watts,
and the auxiliary outlets are also protected by a breaker.
3.5 Control input
The LDS-610 accepts DMX 512 1990 as specified by USITT. Reliable DMX systems require
cable rated for high-speed data communication; for this reason the use of microphone cable is
NOT acceptable. DMX rated cables are available pre-manufactured from your Leprecon
dealer. For more information on the DMX standard and acceptable cable, see the Appendix at
the end of this manual.
For convenience, DMX in and out connectors are provided on the LDS-610. This allows easy
connection to additional dimmer packs. The DMX standard allows up to 32 dimmers to be
connected to a single DMX controller.
6
For proper operation, it is recommended that the last dimmer in the system have a termination
plug placed in the DMX Out connector. Termination plugs can be purchased, or easily built by
installing a 120 ohm resistor between pins 2 and 3 of the 5 pin XLR.
4 Installation
4.1 Mounting
The LD-610 dimmer is passively cooled, using no internal fans. The heat generated by the
dimmer is dissipated by the extruded metal chassis. For proper cooling, the dimmer must be
mounted so that air is free to circulate around the dimmer. The ambient air temperature
surrounding the dimmer must be less than 100 degrees Fahrenheit.
The LDS dimmer has mounting brackets fitted at each end. These brackets can be rotated to
three different positions for securing the dimmer. The dimmer can be attached to a pipe using
standard pipe clamps, suspended from threaded rod, or bolted directly to a beam. Keep in
mind that the mounting method must be sufficient to support the weight of the dimmer, 36 lbs.
4.2 LDS Options
To make mounting the LDS dimmer easier, we offer three types of accessory mounting kits.
Contact your Leprecon dealer or check our website for more information about these kits.
●
C Clamp - This kits include all parts needed to hang a single dimmer from a pipe using
two standard C clamps and safety cables.
●
Threaded Rod – Attach to 3/8 threaded rod, includes a mounting point for a batten
below the dimmer for attaching fixtures.
●
Double-pipe – Hangs the LDS dimmer from a pipe, and attaches a second pipe below
the dimmer.
Instruction are included with each of the option kits that explain the proper use with the LDS
dimmer.
4.3 Power Connection
The LDS dimmer provides a hole in the left end plate that is sized for standard ¾ inch EMT
conduit fittings. See the power requirements chart in section 2 for determining correct wire size
and over-current protection needed for your application.
A plastic cap is installed in the end plate at the factory, and is to be removed at the time of
installation.
Inside the LDS-610 dimmer at the left end is the connection terminal block. There is a four
position terminal block and a ground lug for power connection. If the power supply is three
phase, connect the hot conductors to the red, black and blue lugs. The white lug is for the
neutral connection, and the copper ground lug is the safety ground connection.
If the dimmer is to be used with single phase power, connect the hot leads only to the black and
red terminals. Check the phase switch setting as described below.
7
4.4 Optional power cable
Leprecon offers pre-assembled cord assemblies for the LDS, consisting of 10-5 jacketed cable
with 30 Amp twist plug installed. Contact your dealer for price and availability of the power cord
option.
4.5 Single Phase switch
The LDS-610 dimmer can be set in the field for either single phase or three phase power. To
the left of the power inlet block is a toggle switch. The switch position marked '3' sets the
dimmer for three phase power. Moving the switch to the '1' position configures the dimmer for
balanced operation on single phase power.
Note: Changing the position of the Single Phase switch will change the current draw from the
power source! Refer to the chart on page 4 to make sure that you have properly sized the
power wiring for single phase use.
4.6 Load Connection
The LDS-610 dimmer is offered with three different load connectors. The options are 20 amp
stage pin, Nema 5-15 duplex, or L5-20 Twist connector. Lamp loads are simply plugged
directly into the dimmer. Maximum load capacity for each circuit is 1200 watts.
Each circuit is protected by a front-panel mounted thermal-magnetic breaker. Overload or
shorted lamp loads will cause this breaker to trip. Check and remedy the cause of the overload
before resetting the breaker.

The LDS-610 dimmer uses a 4 digit display and four entry switches to set pack functions, and
display operating status. There are 5 basic menus that are used to set the dimmer operation.
5.1 Address Menu
When the dimmer is first turned on, the display shows the starting channel address of the LDS-
610. This is the DMX address that will control the first channel of the pack.
When there is no DMX input, the channel number is preceded by the letter A for address:
When valid DMX is detected, the letter ‘A’ is replaced with the letter ‘d’ for DMX:
The UP/DOWN keys change the value for the start address. The LDS-610 uses the
changed value immediately and permanently saves it after 10 seconds or if the Enter or
Menu key is pressed.
After power on, the LDS-610 remains in the Address Menu in its simple interface mode. To go
to any other menu requires the user to hold the MENU key for about 5 seconds.

The Channel Mode Menu allows setting one of four basic modes for each dimmer channel.
The Channel mode is indicated by the letter ‘c’ in the display:
Set the mode for the displayed channel by pressing the UP/DOWN keys. The choices for
channel modes are:
Mode Description
Ln Linear output. Standard dimmer channel.
Nd Non-dim. Fader input above 60% turns on channel to 100%. Input
below 40% turns off channel.
FL Florescent output. Dimmer does not begin to turn on until 20%.
00-FF Fixed output level. Values are 0, 10-99 and FF. FF is 100% output.
After changing the mode the colon will blink to indicate new data has been entered. Press the
ENTER key saves the change, and advance to the next channel.
The LDS-610 returns to the Address Menu automatically after 4 seconds if no keys are pressed
in the Mode Menu.

When the LDS-610 is in the Channel mode, pressing the ‘MENU’ switch again will change the
dimmer display to the Status mode. When Status mode starts, the state of each channel will be
shown in sequence, with the display cycling from Channel 1 to Channel 6, then automatically
cycle back to channel 1. This automatic cycling is indicated by the flashing colon.
The Status Mode first displays the current input state of the dimmer channels 1-6. If valid DMX
is present, the letter ‘d’ is displayed, followed by the DMX value for the channel:
If there is no DMX present, the ‘d’ letter will disappear, and a ‘-‘ will be shown instead:
Once the input levels for all dimmer channels have been shown, the display will then indicate
the output level for each channel. This is indicated by the letter ‘o’ in the display, followed by
channel number, followed by output level. Output will be shown as a percentage, with 100%
indicated by the letters ‘FF’
Pressing the ENTER, UP or DOWN keys stops the automatic cycling. Pressing MENU turns
automatic cycling on and off.

Suite 5A
New York, NY 10011-4206
Several web sites exist that have an abundance of information regarding DMX-512. As with
any Internet information, consider the source.
The DMX 512 standard is designed as a simple, reliable system for connecting digital dimmers
and controllers. The protocol allows up to 512 dimmers to be connected to a single control
console. With 512 dimmers in a system, DMX 512 allows each dimmer level to be updated 44
times each second.
8.1 Connectors
The DMX standard specifies the use of 5 pin XLR connectors. DMX 512 currently uses 3 pins
of the 5 pin connector. Pins 4 and 5 are reserved for future use. Some manufacturers are using
these pins for communications back from the dimmer to the control console, or as a redundant
data line.
The connectors to be used for DMX 512 are as follows:
Console end (transmitter) Female 5 pin XLR
Dimmer end (receiver) Male 5 pin XLR
