When power is applied to the unit, the load will turn on immediately.
Set the timeout to 10 seconds (commissioning only) vacate the room or remain very still and wait for the load to switch
off .
Check that the load switches on when movement is detected.
Power-up test procedure
What if the load does not turn ON?
 Check to see if the Vitesse Plus marshalling box is powered up and the wiring is correct. Disconnect both RJ45
connections on the Cat 5 patch lead and re-connect, ensuring that they “click” into position, making good connection.
 Check that the “lux hold off” setting is not keeping the lights off because there is sufficient ambient light.
 If the detection range is smaller than expected, check the diagram above. Rotating the sensor slightly may improve
the range. If still reduced it may be compromised by the ceiling construction / material. Add the supplied 20mm
spacer ring. See page 3 for fitting details.
 If the LED is flashing at regular intervals, this shows that the detector is being overridden. Press the cancel button on
the handset.
HINT: The Walk Test LED function can be used to check that the unit is detecting movement in the required area.
What if the load does not turn OFF?
 Ensure that the area is left unoccupied for longer than the selected timer setting.
 Make sure that the sensor is not adjacent to circulating air, heaters or lamps.
 If the LED is flashing at regular intervals, this shows that the detector is being overridden on. Press the cancel button
on the handset.
Fault finding
The UNLCDHS has the ability to read back the settings stored in a device.
To read back individual parameters

Navigate to the parameter and press the ‘R’ (Read) button whilst pointing at the device. The handset will click
when the parameter has been read back, the device will flash its LED, and the value will be shown against the
parameter in the menu.
To read back all of the parameters in a menu

Press and hold the ‘R’ (Read) button for more than 1 second.
 The handset will click every time a parameter is received
 The device will show multiple flashes of its LED
 All of the values will be shown against the parameters in the menu.
 The individual parameters may be edited and then saved as a ‘Macro’.
Notes

If a parameter(s) has been missed because of a communication error, the missing value(s) is replaced by dashes.
 When reading back, the outputs of the LCM will temporarily be switched off, and will return to their normal state 2
seconds after the read back has been completed.
