After starting (triggering), the output executes the following basic Cycle: 

Fade from a Start Level to a Hold Level, Hold at that level, and then fade back to the Start Level.

The PIC/AXE program data loader is an optional hand held accessory with switches and an LCD Display and is used to program the various time and level settings.  Once programmed with the PIC/AXE (or at the factory) the L129 is a stand-alone controller.

The PIC/AXE can also function as a remote control in Run mode.

The control section may be supplied separately or with an integral dimmer.

If control section is ordered separately, its output can be configured as 0 to 10VDC or 0 to 5VDC Control (or consult regarding DMX-512) to control an external dimmer.
