Typical Output Module
The label on the right side of each module indicates the type of module:
•
UDMT = Dimmer/Switch module
•
USMT = Switch module
The Channel Select buttons have multiple uses.
•
They can be used to select that channel for configuration or viewing when using
either the
“VIEW CURRENTS”, “CONFIGURE CURRENTS”, “VIEW LEVELS”,
“DIMMER SETUP” or “VIEW CHANNELS” menus
•
They can be used to force a channel into EMERGENY MODE. See section 4.
The Channel, Comms and Status LEDs are described in section 2.1.2
1.5.4
UDMT Dim + Switch Output Module
The UDMT provides 12 output channels. Each channel can be individually configured for either
dimming of traditional incandescent lamps or relay power switching.
In dimming mode, the module utilizes pulse transformer circuitry which allows it to control
difficult loads including neon, motors and low wattage lamps, without the need for a dummy
load. The dimmer circuitry also employs high quality and virtually silent chokes with a Rise
Time of 220µS (measured between 10% and 90% at 50% output level into maximum rated
load).
In switching mode, the module uses LSC’s “TruPower” technology that bypasses the dimmer
circuitry and directly connects the output circuit to the incoming power via a mechanical relay.
It also uses “Current Control Technology” where power switching occurs when the mains
voltage is at zero volts (zero crossing point) to prevent nuisance tripping of breakers. The
operation of each power switching relay can be controlled by either the level of its DMX
channel or automatically switched on when the DMX control signal is present and off (after a
programable delay of up to 60 minutes) when DMX is no longer present or always on. See
section 3.6
1.5.5
USMT Switch Output Module
The USMT provides the same features as the UDMT above, but without the ability to dim
making this module a more cost effective choice when dimming is not required.
