The LCM-ASTRO series control panel is a cost-effective and easily configurable stand-alone contactor-based lighting control system with programming specifically optimized for exterior applications. It is capable of supporting 2 or 3 zones with photo, astronomical time clock, remote switching and timed override.
A maximum of four (4) contactors can be accommodated in each 2- or 3-zone main panel. In addition, up to twelve (12) contactors are available in each expansion panel. Contactors are available in 4- and 8-pole configurations.
The four line LCD screen prompts the user to enter photo sensor set point limits and time schedules which are saved in flash memory. Adjustments to the settings and schedules can be made with pushbuttons on the controller face. Timed functions are controlled by an internal real-time astronomical clock. The battery-backed clock is accurate to one second per month and can be adjusted for drift. Timed circuits are automatically adjusted for daylight savings time and leap year unless otherwise specified.
The LCM-ASTRO series advantages include stability, versatility, quality, accuracy and the ability to control exterior lighting without using a photosensor. Once mounted, the sensor, power, and lighting loads need only to be wired and the LCM is ready to operate. The system controller has specific application control strategies that are matched with the appropriate sensor to create optimal packaging and system efficiency.
