Changing A Module Type - Leviton DMX-512 Installation And Operating Manual

Leviton MDS Dimmer Cabinets with Luma-Net Control
• ND. The module is set up for On/Off operation only. As the input signal
approaches 40% the module switches full On. When the input falls below about
38% it switches Off. The slight difference in level is called hysteresis and is
used to prevent chattering at the switching point.
• LV. A normal dimmer but with a low-end cutoff. This can be useful for certain
load types such as driving a stepdown transformer for low voltage lights where
a complete turnoff is needed at some low light level.
By pressing the UP
modules to determine how they are programmed, if they are receiving an
input, and the source of that input. If a dimmer is being driven from two
inputs (for example Luma-Net and DMS512), whichever input is higher
has control, and that name appears.
This controller is capable of controlling up to 24 dimmers. In many of the MDS
dimmer cabinets there are more than 24 dimmers, so you may find more than one
controller electronic module. Each of these is capable of controlling another group
of 24 dimmers. A cabinet containing 70 dimmers would require three of these
electronic circuit cards providing a total of 72 available channels.

Changing a Module Type

Changing a module type involves the use of a password (setup code) to prevent
unauthorized changes of vital data within the digital module. The factory default
password is 0000.
If the password is lost or forgotten you will have to contact the factory to
regain access to your system setup menus. If your system normally
resides in a locked electrical room it may be best to keep the default
password.
