Functions and Features

This product allows luminaire design to be simplified as the luminaire body no longer needs to be drilled to accept a photocell for assessing the daylight condition. It will measure the ambient natural light behind the cover then calculate how much artificial light is needed to reach the target lux level. The required dimming level control is passed to the driver by the 0-10V signal for delivering the right amount of light.

The light will be dimmed to minimum level and switched off eventually if ambient daylight is sufficient, regardless of hold-time or stand-by time, with or without motion.

1 Photocell Advance (Lux off Function)

The built-in sensor can measure ambient natural light from behind the cover, dim and eventually switch off the fixture when artificial light is not required. What’s more, if the stand-by time is pre-set at "+∞", the fixture can automatically turn on at dim level when natural light is insufficient.

2 Daylight Harvest (Daylight Regulating)

The light remains off when natural light level exceeds daylight threshold preset, even if motion detected.

The light switches on with presence when natural light is insufficient.

The light output regulates from full brightness to minimum dim level according to the change of daylight brightness, so as to maintain the target lux level.

Note:

1. The light will automatically turn on at target dim level or turn off based upon ambient natural light lux level during stand-by period if it is preset to ‘+∞’.

2. The target lux level can be adjusted by remote control or long press on the push switch.

The light eventually switches off whenever ambient daylight is sufficient, even with presence.

The light dims to target stand-by brightness after hold-time.

The light switches off after the stand-by period.

3 Synchronization Control Function

By connecting the “SYNC” terminals in parallel (maximum 10pcs, see wiring diagram next page), no matter which sensor detects motion, all HC419VRC/DH connected will turn on the lights when surrounding natural light is below the daylight threshold which can be set by either DIP switch on the sensor unit or remote control HRC-11. The sensor antennas are effectively ‘shared’ and the detection area is widely enlarged in this way.

Note: To avoid fixtures turning on unnecessarily, daylight sensing takes priority on a point-by-point basis. Occupancy sensing

(SYNC) is disabled on those units in which the ambient light exceeds the daylight threshold.

4 Zero-cross relay operation

Designed into the software, sensor switches on/off the load right at the zero-cross point to ensure the in-rush current is minimized, enabling the maximum lifetime of the relay.

5 Manual Override (Push Function)

By using a momentary push-to-make switch, this sensor maybe over-ridden by the end-users to switch on/off the lights manually, or adjust the light brightness during motion hold-time. This makes the product more user-friendly and offers more options to fit for extra-ordinary demands.

* Short push (<1s): on/off function;

On → off: the light turns off immediately and cannot be lighten for a certain time (equals to hold-time preset) even movement is detected.

After this period, the sensor goes to sensor mode.

Off → on: the light turns on 100% and goes to auto sensor mode, even when ambient Lux level exceeds the daylight threshold.

* Long push (>1s): adjust the target lux level by turning the light up or down. Both the adjustment on remote control and push switch can

overwrite each other, the last adjustment remains in memory.

Note: if no end-user adjustment is desired, simply leave the “push” terminal disconnected.

6 Semi-auto Function (absence detection)

It is easy to forget to switch off the light, in offices, corridors, or even at home. In many other cases, people do not want to have a sensor to automatically switch on the light, for example, when people just quickly pass-by there is no need to have the light on.

The solution is to apply this “absence detector”: motion sensor is employed, but only activated on the manual press of the push switch. With presence, the light remains on and can interact with ambient natural light, then dims down in absence, eventually switching off automatically after the stand-by time has expired.

Light does not switch on when there is motion detected.

Short press on the push switch to activate the sensor and turn on the light.

The light turns up or down according to the change of daylight brightness.

The light turns off completely when artificial light is not required, even with presence.

The light automatically dims to stand-by brightness after hold-time.

The light turns off eventually after the stand-by time has expired.

Note2: The end-suer may also switch off the light manually with a short press of the push switch

Settings (Remote Control HRC-11)

Permanent ON/OFF function

Press “ON/OFF” button, the light goes to permanent ON or permanent OFF mode.

* Press button “SEMI-AUTO/AUTO” or button “RESET” to resume automatic operation.

Reset function

Press “RESET” button, all settings go back to the DIP switch settings.

Shift

Press button “Shift” , the LED on the top left corner flashes to indicate mode selection. All values

/ settings in RED are valid for 20 seconds.

Automatic mode

Press “SEMI-AUTO/AUTO” to initiate automatic mode. The sensor starts working and all settings remain as before the light was switched ON/OFF.

Semi-auto Mode

1. Press button “Shift”, the red LED flashes for indication.

2. Press button “SEMI-AUTO/AUTO” to initiate semi-auto mode. The fixture is manually turned on by pressing the push-switch, and goes off automatically after stand-by time. (Absence detection mode)

Power output

By pressing these two buttons, the light output shifts between 80% and 100%.

Note: the function of “Sensor off” and “Twilight” are disabled.

Scene program_ 1-key commissioning

1. Press button “Start” to program.

2. Select the buttons in “Detection range / Daylight threshold / Hold time / Stand-by time / Stand-by dimming level” to set all parameters.
