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 Channel 1 relay (where fitted) will temporarily be switched off, and will return to it’s
normal state 2 seconds after the read back has been completed.
Readback function (only with UNLCDHS handset )
When power is applied to the unit, the load will turn on immediately.
Set the timeout to 10 seconds, 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.
The unit is now ready for programming.
Power-up test procedure
What if the load does not turn ON?
 Check that the live supply to the circuit is good.
 Check that the load is functioning by bypassing the sensor (e.g. link terminals L and L/ Out).
 If the detection range is smaller than expected, check the diagram on page 2. Rotating the sensor slightly may
improve the detection range.
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 Time Out Period.
 Ensure that the sensor is not adjacent to circulating air, heaters or lamps.
 If the unit “false triggers” reduce the sensitivity using the sensitivity settings
