1. ALC AD Product Guide EEN Priectronies Ceiling mounted photocell for 1 10V dimming Overview The ALC AD dimming photocell automatically adjusts the light output of luminaires depending on the amount of natural light available to maintain constant brightness maintained illuminance using 1 10V control An optional manual control using a switch input allows the user to override the dimming levels and turn the output on and off In addition to changing the output level the photocell can be set to turn lighting on when the ambient light falls below a preset level The lighting can also be set to turn off when the total light level rises above a separate preset level An integral adjustable time delay prevents nuisance switching caused by for example dark clouds All functionality is fully programmable using an IR handset Front features Mounting Bezel Ng a i Sensor Lens which covers IR Receiver Light Level Sensor Status LED Back features Retaining Spring Dimmable Control Output Connector Channel 2 Power Input amp Switched Output Connector Channel 1 Switch Input Retaining Spring Connector IR Receiver Receives control and programming commands from an IR infrared handset Light Level Sensor Measures the overall light level in the detection area Status LEDs The LED flashes Red to indicate the following I o gt lt 4 Valid setting received SRS Power Input2. amp Switched Output Connector Channel 1 Used to connect mains power to the unit and to connect a switched load Dimmable Control Output Connector Channel 2 Used to connect 1 10V controllable ballasts and transformers for dimmable loads Switch Input Connector Two input terminals can be used to manually override the dimming levels and override the lights on or off Installation Choosing a Suitable Location The ALC AD is designed to be ceiling mounted and must satisfy the following criteria e Avoid positioning the unit where direct sunlight may enter the sensor element Sensor functionality Switch Level On Off The device can be made dependant on the ambient light level using the Lux On Level and Lux Off Level parameters Brighter Lux Off Level Ambient Light Level Lux On Level Darker Maintained Illuminance daylight harvesting The detector measures the overall light level in the detection area and calculates the correct output for the luminaires to achieve a preset lux level maintained illuminance or daylight harvesting Overview It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of time to guarantee lamp life refer to the manufacturer s datasheet for details As this ALC AD is able to dim the lamps using 1 10V the product provides a facility to disable this for a given period of time Operation By setting the Burn in para
