Introduction

The new ULD series dimmer is designed to be a capable and reliable solution

for temporary and portable dimming requirements. 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.

Please take a few minutes to review the specifications and operating features

of the ULD-340 dimmer.

The ULD-340 dimmer is designed for use with conventional incandescent

fixtures. Transformer 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.

For operating florescent fixtures, see the section regarding Front Panel Controls.

2) Specifications

Power Connection

Unless otherwise indicated, your ULD-340 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 overvoltage

protection circuit and shut off the dimmer pack.

Ambient

Temperature

The ULD-340 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.

Power

Capacity

The ULD340 DMX is unique in the market of small portable dimmers. A single

breaker is used on the pack instead of individual fuses per each channel. As a

result, the limits of the dimmer are pack limits, not channel limits. The following

guidelines should be followed:

ULD340 DMX-HP – when plugged into a 100% duty-cycle service or a wall

socket in the USA

Pack Limit: 15 Amps (1800 watts) for each of the 2 power input cables, or 30

amps (3600 watts) total

Individual channel limit of 18 watts

- 5 -

Example 1: 15 watts on channel 1, 6 watts on channel 2, 18 watts on channel 3 and

nothing on channel 4

Power input cable A and breaker A control channels 1 and 2. The maximum wattage per power

input cable is 18 watts. You have 21 watts on the 2 channels (15 + 6 ) so the breaker

will trip. You will have to remove some lights.

Power input cable B and breaker B control channels 3 and 4. The maximum wattage per power

input cable is 18 watts. The maximum wattage per channel is also 18 watts, so an 18 watt

load will be OK, as there is no load on channel 4 and the pack is on a 1 % duty cycle service.

ULD340 DMX-HP – when plugged into a normal wall outlet in Canada

Pack Limit: 12 Amps (1500 watts) for each of the 2 power input cables, or 24

amps (3000 watts) total

Individual channel limit of 15 watts

Example 2: 13 watts on channel 1, 6 watts on channel 2, 15 watts on channel 3 and

nothing on channel 4

Power input cable A and breaker A control channels 1 and 2. The maximum wattage per power

input cable is 15 watts. You have 19 watts on the 2 channels (13 + 6 ) so you will trip

the breaker.

Power input cable B and breaker B control channels 3 and 4. The maximum wattage per power

input cable is 15 watts. The maximum wattage per channel is also 15 watts, so a 15 watt

load will be OK on channel 3, as there is no load on channel 4.

Control input

The ULD-340 DMX accepts DMX 512 1990 as specified by USITT. Reliable DMX

systems require cable rated for data communication at 250K baud; for this reason the

use of microphone cable is NOT recommended. 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 ULD-340DMX. This

allows easy connection to additional dimmer packs. The DMX standard allows up to 32

dimmers to be connected to a single DMX controller.

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.

3) Installation

Mounting

The ULD340 is designed for vertical mounting. The top hanging bracket has a

pre-punched hole for a standard ½” pipe clamp mounting bolt. Using this

mounting point allows the dimmer to be mounted with the power cords, DMX

display and DMX control connectors facing downward.

The ULD340 dimmers are passively cooled, using no internal fans. The heat

generated by the dimmer is dissipated by the extruded metal chassis, and the

airflow through the chassis vents. For this reason, mount the dimmer so that air

is free to circulate around the dimmer. The dimmer should be mounted with at

least 12 inches of clearance between the dimmer and any ceiling or obstruction

above the dimmer that would block air circulation.

Power Connection

Leprecon LD340 series dimmers are supplied with line cords which have

standard TLG plugs attached. Each line of the LD340 should be connected to a

service capable of supplying 15 amps @ 100% duty cycle and protected by a

properly sized circuit breaker.

If you have any questions about the suitability of the power circuit that you

intend to use with the LD340 dimmer, consult with a qualified electrician.

Load Connection

Lamp loads are plugged directly into the outlets on the body of the dimmer.

4) Turning on Power

The ULD-340 has two line cords and two circuit breakers. The line cord and

breaker to the left on the endplate, labeled ‘A’, supplies power for channels 1

and 2, as well as the internal power supply for the control electronics. Line cord

and breaker ‘B’ supplies power to channels 3 and 4.

Power applied to the dimmer is indicated by an internal green indicator in each

of the breakers. If the breaker is on, but not lighted, there is no power to the line

cord. Turning on breaker ‘A’ will also light the red LED display.

Note:

The unit can be Reset to original factory settings by depressing and holding the

ENTER switch while turning on the first breaker.

5) Front Panel Controls

The ULD-340 dimmer uses a 4 digit display and four entry switches to set pack

functions, and display operating status.

Resetting the ULD-340 to default values:

The unit can be Reset to original factory settings by depressing and holding the

ENTER switch while turning on the first breaker.

Address

When the dimmer is first turned on, the display shows the starting channel

address of the ULD-340. 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:

004

When valid DMX is detected, the letter ‘A’ is replaced with the letter ‘d’ for DMX:

004

- 8 -

The UP/DOWN keys change the value for the start address. The ULD-340 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 ULD-340 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.

Channel Mode Menu

The Channel Mode Menu allows setting the mode of each dimmer channel.

This mode is indicated by the letter ‘c’ in the display:

c2:

Set the mode for the displayed channel by pressing the UP/DOWN keys. The

possible 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.

lorescent output. Dimmer does not begin to turn on until 20%.

00-FF

ixed 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 LD-340 returns to the Address Menu automatically after 4 seconds if no

keys are pressed in the Mode Menu.

Status Menu

When the ULD-340 is in the Channel mode, pressing ‘MENU’ again will start 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 4, 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-

4. 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:

-1

- 10 -

d1:00

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 b the letters ‘FF’

Pressing the ENTER, UP or DOWN keys stops the auto cycle mode and enters

manual mode. Pressing MENU toggles between auto and manual cycle modes.

In manual mode the menu steps through its displays when the UP or DOWN

keys are pressed. The colon is steady in manual mode.

If a channel has been set to a fixed level in the Channel menu, the output status

will reflect that level. In this case, the input for channel 1 could be zero, but

there could be a non-zero output level.
