Note: 1. Motion sensor overwrites daylight sensor, meaning the daylight sensor starts to check the ambient
natural light only when the lamp is switched off (motion hold-time elapsed).
2. 1-10V output on the master unit HC028V /RF is isolated, SELV output.

MALFUNCTION CAUSE REMEDY
CAUSE
REMEDY
The load will not work
The load is always on
The load will not work
despite movement
Check zone setting
The load 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.
Load faulty
Mains switch OFF
Adjust setting
Replace load
Switch ON
Check zone 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.
