SECTION 4 FUNCTIONS

4.1 Zero-cross Relay Operation

4.2 Synchronization Function

4.3 Manual Override 

4.4 Absence Detection Function

4.5 Daylight Monitoring Function

Designed in the software, the sensor switches on/off the load right at the zero-cross point, to ensure the in-rush current is minimised, enabling the 

maximum life-time of the relay.

Note: if the surrounding natural light of the sensor which detects movement is sufficient,all lights in the group will remain off. 

By connecting the “SYNC” terminals in parallel (maximum 10pcs, see wiring diagram), no matter which sensor detects motion, all HC419VRC/R in 

the group will turn on the lights when surrounding natural light is below the daylight threshold. The sensor antenna is shared and the detection 

area could be widely enlarged in this way. Other settings such as hold-time, stand-by period, stand-by dimming level and daylight threshold on 

each individual unit stay the same.    

The motion sensor is employed, but only activated on the maunal press of the push switch, light will remain on in presence, and dimmed down in 

the absence, and eventually switch off automatically in the long absence.   

Hytronik specially designed this function in software for deep energy-saving purpose. A built-in daylight sensor is designed to provide a “smart 

photocell” function. This function can only be activated when stand-by period is set to “+∞”. In this mode the lamp will automatically illuminate at the 

dim level setting when the natural light goes below the threshold setting. The fixture will also switch off as the natural light returns. 

This sensor maybe over-ridden by the end-users to switch on/off the lights manually, or adjust the maximum brightness during motion hold-time 

with the push-switch. 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 there is movement is  

                     detected. After this period, the sensor goes back to auto 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 maximum brightness (between 10% and 100%) during hold-time. Both the settings on DIP switch and manual      

                              override can overwrite each other, the latest action controls. 

* If no end-user adjustment is desired, simply leave this terminal disconnected.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

 

MALFUNCTION CAUSE REMEDY

CAUSE

REMEDY

The light will not come on

The lamp is always on

The lamp will not work 

despite movement

Check detection area  setting

The lamp is on without any 

identifiable movement

Incorrect light-control setting selected

Continuous movement in the detection zone 
The sensor is not mounted for reliably 

detecting movement

Movement occurred, but not identified by the 

sensor (Movement behind wall, movement of 

small object in immediate lamp vicinity etc.)

Rapid movements are being suppressed to 

minimize malfunctioning or the detection 

radius is too small.

Faulty lamp
No power supply

Adjust daylight threshold setting
Replace lamp
Check power to sensor
Check detection area setting

Securely mount enclosure

1. Reduce sensitivity.

2. Check the movement behind 

    walls to avoid facilities such as 

    water pipe, fan, which may 

    mis-trigger the sensor.
