Sensor functionality

Detection Mode

The Detection Mode can be set to behave in Presence or Absence mode:

 Presence When movement is detected the load will automatically turn on. When the area is no longer occupied the

load will automatically switch off after an adjustable time period.

 Absence The load is manually switched on. When the area is no longer occupied the load will automatically switch

off after the adjustable time period has elapsed.

In either case, sensitivity to movement of the PIR sensor can be adjusted using the Sensitivity parameter.

HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.

Switch Level On/Off

Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level

parameters.

Installation

Choosing a Suitable Location

The EBDHS-PRM-LT30 is designed to be ceiling mounted and must satisfy the following criteria:



Avoid positioning the unit where direct sunlight may enter the sensor element.



Do not site the sensor within 1m of any lighting, forced air heating or ventilation.



Do not fix the sensor to an unstable or vibrating surface.

EXTERNAL CIRCUIT

PROTECTION 10A

Absence detection



To use absence detection a retractive (momentary) switch must be connected between the 2 terminals on the

diagram. Note that this will be switching mains voltage.



The unit ships with presence detection as default. To change to absence detection, press and release the external

switch 5 times within the first minute of power up. The LED will turn on solid for 30 seconds to indicate absence

mode has been selected.



To change back to presence detection, repeat the above procedure—the LED will flash for 30 seconds to indicate

presence mode has been selected.

Note: the above adjustments can also be made using the UHS5 or UNLCDHS handsets. See Programming sections.

Readback function

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.
