Note:
- When HIR17 or HIR17/R plug with HCD038/P, only one push terminal can be activated for configuration.
- Only when both HCD038/P and HIR17 or HIR17/R are used together, then the combination is DALI-2 enabled as a whole.
HIR17 can freely switch between tri-level control and daylight harvest through remote controller HRC-11 setting.
Note:We recommend the mounting distance between sensor to sensor should be more than 2m to prevent sensors from false-triggering.
Functions and Features
- Tri-level Control (Corridor Function)
Hytronik builds this function inside the motion sensor to achieve tri-level control, for some areas which require a light change notice before switch-off. The sensor offers 3 levels of light: 100%–>dimmed light (natural light is insufficient) –>off; and 2 periods of selectable waiting time: motion hold-time and stand-by period; Selectable daylight threshold and freedom of detection area.With sufficient natural light, the light does not switch on when presence is detected.
With insufficient natural light, the sensor switches on the light automatically when presence is detected.
After hold-time, the light dims to stand-by level if the surrounding natural light is below the daylight threshold.
Light switches off automatically after the stand-by period elapses.
- Daylight Harvest
Light will not switch on when natural light is sufficient, even there is motion detected.
The light switches on automatically with presence when natural light is insufficient.
The light turns on at full or dims to maintain the lux level. The light output regulates according to the level of natural light available.
The light switches off when the ambient natural light is sufficient.
The light dims to stand-by period after hold-time and stays on selected minimum dimming level.
The light switches off completely after the stand-by period.
Note:
The Light automatically dims down and eventually turns off if the natural light lux level exceeds the daylight threshold. However, if the stand-by period is preset at “+∞”, the fixture never switches off but dim to minimum level, even the natural light is sufficient. - Master (HCD038/P)
HIR17 supports multiple sensors to access DALI network at the same time. In order to prevent conflict during daylight harvest control, you need to manually select one HIR17 as the master when configuring the network. The master has the control authority of this DALI network. Other HIR17 will only report sensing events.
Active Lux Switching (Daylight Detection Prior to Motion Detection)
The built-in photocell will also automatically turn off the light when the ambient ambient light exceeds the programmed lux level for more than 5min, regardless of whether motion is detected or not.
With sufficient ambient light, the light does not switch on when presence is detected.With insufficient ambient light, the sensor switches on the light automatically when presence is detected.
The sensor switches off the light when ambient light is sufficient, even with presence.
Manual Override
This sensor reserves the access of manual override function for end-user to switch on/off, or adjust the brightness by push-switch, which makes the product more user-friendly and offers more options to fit some extra-ordinary demands:
* Short Push (<1s): on/off function;
On → Off: the light turns off immediately and cannot be triggered ON by motion until the expiration of pre-set hold-time. After this period, the sensor goes back to normal sensor mode.
Off → On: the light turns on and goes to sensor mode, no matter if ambient Lux level exceeds the daylight threshold or not.
* Long Push (>1s): adjust the hold-time brightness level between10% and 100%.
Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.
Semi-auto Mode (Absence Detection)
It is easy to forget to switch off the light, in office, corridor, even at home. And in many other cases, people do not want to have a sensor to switch on the light automatically, 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, the light keeps being ON in the presence, and dims down in the absence, and eventually switches off in the long absence. This is a good combination of sensor automation and manual override control, to have the maximum energy saving, and at the same time, to keep efficient and comfortable lighting.
The light does not switch on when there is presence being detected.
The light turns on full, and the sensor stays in sensor mode.
The light keeps being ON during the presence.
People left, the light dims to stand-by level after the hold-time.
The light switches off automatically after the stand-by period elapses.
Note: end-user can choose either function5 or function6 for application. Default function is manual override.
Zero-cross Relay Operation (HC038V)
Designed in the software, sensor switches on/off the load right at the zero-cross point, to ensure that the in-rush current is minimised, enabling the maximum lifetime of the relay.
Loop-in and Loop-out Terminal (HC038V)
Double L N terminal makes it easy for wire loop-in and loop-out, and saves the cost of terminal block and assembly time.
