a stand alone chaser and has eight primary preset chase patterns which may be used. An additional manual
operating mode is available which enables the unit to function as a stand alone dimmer with manual control of
each channel.
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-40M is 2400 watts.
LOAD CONNECTIONS: There is one Edison Plug connector provided for each AS-40M 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 AS-40M 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 AS-40M dimmers must be powered by other means.
Wiring information for the DMX control signal connectors is shown on the unit top cover.
