DESCRIPTION
The AS62L is a compact 4 channel light dimmer. It
has a maximum capacity of 1200 Watts per channel
and maximum total load capacity of 4800 Watts. It is
supplied with 2 input power cord stubs which may be
connected to 2 different 120 VAC power phases.
The AS62L is intended for INDOOR USE ONLY.
The unit operates using the industry standard three
wire multiplex protocol. The AS62L may be operated
in a relay (non-dim) mode. The unit will also function
as a chaser and has several preset chase patterns
which may be used.
INSTALLATION
LOCATION: Locate the unit vertically with control
signal connectors on bottom in a well ventilated area
away from moisture and heat. Two ½” holes are
provided on the dimmer top cover to install a lighting
bar pipe clamp and a suitable safety cable.
POWER CONNECTIONS: Extending from the
chassis are two 20 amp line cords for connection to
2 separate 120 VAC, 20 Amp, grounded services in
any phase combination. Total capacity of the AS62L
is 4800 Watts.
LOAD CONNECTIONS: There are 6 numbered
duplex outlets on the top of the unit. Each provides
2 connections for one of the output channels. You
can connect up to 1200 Watts of lighting to a single
channel.
The total load capacity of the
AS62L channels 1, 3, and 5 combined is
limited to 2400 Watts. The total load
capacity of the AS62L channels 2, 4, and 6
combined is also limited to 2400 Watts.
CONTROL SIGNAL CONNECTIONS
The male three pin XLR connector on the unit end
panel connects to the control console. The female
connector is for connection to additional dimmers.
The AS62L dimmer LMX-128 protocol is compatible
with the Lightronics and NSI/Sunn three wire
multiplexed protocol. If you have older Lightronics
dimmers which run in the obsolete Lightronics mode
only, contact Lightronics for information on changing
the mode. When using multiple dimmers, ALL
dimmers MUST be in the SAME mode.

AS62L END VIEW
OPERATION
NORMAL MODE (non-chaser)
A green LED in the end panel will indicate that a
valid control signal is applied to the unit. A DIP
switch block on the end panel selects the starting
channel number of the dimmer. The 8 right hand
switches control this function. For example, if all
switch positions are down - the dimmer will respond
to channels 1-6. Moving the switch position on the
far right up will set the dimmer to respond to
channels 3-8. 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
and/or 5/6) 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 3 left hand switches on the DIP switch
block control relay mode channel selection.
CHASER MODE
When operating in the chaser mode the AS62L
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.
