LIGHTRONICS AS40D 4 X 600w Compact Dmx Dimmer Owner's Manual
DESCRIPTION
The AS40D is a compact 4 channel light dimmer. It has a maximum capacity of 600 Watts per channel and a maximum TOTAL load capacity of 2400 Watts. It is supplied with an input power cord which may be connected to a 120 VAC, 20 Amp power circuit. The AS40D is intended for INDOOR USE ONLY. The unit operates using the USITT DMX-512 protocol. The AS40D may be operated in a relay (non- dim) mode. The unit will also function as a stand-alone chaser and has eight primary preset chase patterns which may be used.
INSTALLATION
LOCATION:
Locate the unit vertically with control signal connectors on the bottom in a
well ventilated area away from moisture and heat. Two ½” holes are provided on
one end of the dimmer to install a lighting bar pipe clamp and suitable safety
cables.
POWER CONNECTIONS:
Extending from the chassis is a 20 Amp line cord for connection to a 120 VAC,
20 Amp, grounded service. Total capacity of the AS40D is 2400 watts.
LOAD CONNECTIONS:
There is one Edison Plug connector provided for each AS40D output channel.
They are located along the left and right edges of the unit. The markings on
the cover indicate the channel numbers for each connection. The maximum
capacity of each channel is 600 watts.
CONTROL SIGNAL CONNECTIONS:
The male five pin XLR connector on the unit end panel connects to the control console. The female connector is for connection to additional dimmers. The AS40D dimmer is compatible with the USITT DMX-512 protocol.
Note that the DMX standard does not provide for console power via the dimmer
chain. Therefore the DMX console used with AS40D dimmers must be powered by
other means.
Wiring information for the DMX control signal connectors is shown on the unit
top cover.
CHASSIS END VIEW
OPERATION
NORMAL MODE (non-chaser)
A green LED in the end panel will indicate that a valid control signal (DMX) is applied to the unit. A DIP switch block on the end panel selects the starting channel number of the dimmer. The 7 right hand switches control this function. For example, if all switch positions are down – the dimmer will respond to console channels 1-4. Moving the switch position on the far right to up will set the dimmer to respond to channels 5-8. A complete table of channel assignments is provided at the end of this manual. You can address up to 512 channels using DMX control.
RELAY MODE: Pairs of channels (1/2 and/or 3/4) may be switched into relay mode. In this mode, the output of these channels will be either off or full on depending on the control console channel setting. The trip point for turn on is approximately 50%. The 2 left hand switches on the DIP switch block control relay mode channel selection.
NORMAL MODE SWITCH FUNCTIONS
CHASER MODE
When operating in the chaser mode, the AS40D becomes independent of the control console and other dimmers. The green LED indicator is OUT when in the chaser mode. Chaser mode is turned on and off by one of the DIP switches on the end of the unit. A diagram on the unit cover shows the switch settings for controlling chaser operation.
Eight different chaser patterns are available. A “bounce” condition may be
imposed on several of the chase patterns by setting one of the DIP switches.
The bounce condition causes the chase pattern to run in alternating
directions.
The chase step time may be controlled for up to 64 seconds per step. Step fade
time is proportional to the step time. If a channel is in the relay mode
during chaser operation – it will “snap” on and off (zero fade time). The
tables on the next page show the details of chaser settings.
REPAIR
The only AS40D user serviceable parts are externally accessible fuses. Replace
fuses ONLY with 5 Amp, 250VAC, fast blow fuses. Internal service on the unit
by other than Lightronics authorized agents will void the warranty. If service
is required, contact the dealer from whom you purchased the dimmer, or

MAINTENANCE AND REPAIR
TROUBLESHOOTING
- Check that you have power applied to the dimmer.
- Check that all light fixtures are functional.
- Check the fuses.
- Check the DMX control cable
- Check the settings of the dimmer DIP switches.
- Check the console setup for correct patching.
CHANNEL ASSIGNMENT SETTINGS
The DIP Switch Setting column shows the positions of the DIP switches on the dimmer. The Start Channel column shows the resulting channel assignment for the first channel of the dimmer
All Lightronics products using DIP switches for DMX-512 address assignments conform to this table.
NOTE: Some control consoles can be programmed or “patched” to alter their channel order. You may get unexpected results if you are not aware of the console patch condition when you assign channels at a dimmer.
EXAMPLE: If a dimmer’s DIP switches are set to then the first channel of the dimmer will respond to console channel 173. The remaining dimmer channels will respond to console channels 174, 175, 176 …etc.
