1. Operation By setting the Burn in parameter you can select a time during which the lamps are not allowed to deviate from maximum output The unit counts the time and even remembers how long has elapsed in the event of a power failure To cancel the burn in function simply select a time of 0 Note that when the lamps are changed the burn in time should be set again Fault finding What if the load does not turn ON e Check that the live supply to the circuit is good e Increase the Lux on level to switch on at a higher brightness What if the load does not turn OFF e Increase the lux off level to switch off at a lower brightness Load cycles on and off e Increase the difference between the lux on level and the lux off level e Increase the time setting e Angle the sensor away from the light that it is controlling Installation The ALC DD is designed to be mounted using either e Flush fixing or e Surface fixing using the optional Surface Mounting Box part no DBB Both methods are illustrated below Flush Fixing Hole 64mm Warning be careful bending springs when mounting unit Surface Fixing gt Wire stripping details Pull out spring tab and rotate spring arm as shown Important lt 4 Ensure that the cables are formed as shown per before affixing the cable clamp The clamp MUST clamp the outer sheath s only 6 mm Bend cores as shown 35 mm Readback functio2.

4. D2 ALC DD Product Guide EEN Priectronies Ceiling mounted photocell for DALI DSI dimming Overview DALI The ALC DD dimming photocell automatically adjusts the light output of luminaires depending on the amount of natural light available to maintain constant brightness maintained illuminance using either DALI or DSI digital dimming protocol 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 vdi
