DESCRIPTION
The AS-40L 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 AS-40L is intended for INDOOR USE ONLY. The AS-40L is compatible
with the industry standard 3 wire multiplex control signal protocol (LMX). The AS-40L may be operated in a relay
(non-dim) mode. The unit will also function as a stand alone chaser and h as eight preset chase patterns which
may be used.
INSTALLATION
LOCATION:
Locate the unit 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 AS-40L is 2400 watts.
LOAD CONNECTIONS:
There is one Edison Plug connector provided for each AS-40L output channel. They are located along the le ft
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 three pin "XLR" connector on the end of the unit connects to your lighting console. The female "XLR"
connector is used to connect to other dimmers.
CONTROL CABLE WIRING: The XLR multiplex connector pins are wired as follows:
before you operate the AS - 40L dimmer.

CHASSIS END VIEW
OPERATION
NORMAL MODE (non-chaser)
A green LED in the end panel will indicate that a valid control signal (LMX) 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 (numbered
4 -10) 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.
RELAY MODE: Pairs of channels (1/2 and/or 3/4) may be switched into the 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 aprox. 50%. The 2 left hand switches on the DIP switch block control relay mode channel selection.

3/4 DIM/RELAY
1/2 DIM/RELAY
CHASER MODE
When operating in the chaser mode the AS-40L 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 below show the details of chaser settings.

MAINTENANCE AND REPAIR
TROUBLESHOOTING
• Check that you have power applied to the dimmer.
• Check that all light fixtures are functional.
• Check the fuses.
REPAIR
The only AS–40L 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 Lightronics, Service
Department, 509 Central Drive, Virginia Beach, VA 23454. Tel: 757 486 3588.

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 address assignments conform to this table. Some dimmers cannot
be set to all 512 channels and will have fewer switches than are shown in the table. If this is the case then match
the right end switches in the table to your dimmer switches. 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 ШГШГШГГ 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.
