LC8 Controller

LC8SINGLE LEVEL
Lighting Controller
The LC8 lighting controller automatically switches a dry contact in response to changes in natural daylight. The LC8 provides a maintained single pole, double throw “form C” relay output to drive electrically held contactors or relays, or inputs to Energy Management Systems (EMS). The LC8 can control incandescent, fluorescent or HID lighting. The low voltage controller requires a remotely mounted CES or MAS sensor.

The dual setpoint LC8 precisely switches loads according to the selected light level configuration. LOW and HIGH light levels are calibrated to their setpoints at the control board. As the sensor detects a diminishing light level that corresponds with the LOW setpoint, the control board matches the two signals and the lights are switched ON.

As the sensor detects an increased light level, the control board’s HIGH setpoint switches the lights OFF. The LOW and HIGH setpoints are separated by a “deadband”. This prevents the sensor from switching light levels between the setpoints, thus eliminating nuisance or intermittent changes.

For direct switching capability of 120VAC and 277VAC circuits, the LC8 can be used with a switchpack. PLCBuildings UL listed PCS/120 or PCS/277 may be used. All products are factory tested to assure maximum reliability. The advantages of using the LC8 lighting control system are found in stability, versatility, quality and accuracy. The LC8 offers precision light measurement setpoints that are stable once set and the flexibility to be applied to many different lighting environments.
