Choosing a Suitable Location
The detector should be sited so that the occupants of the room fall inside the detection pattern shown opposite).
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.
Avoid metallic objects directly in front of the sensor head.
Overview
It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of time
to guarantee lamp life (refer to the manufacturer's datasheet for details). As this MWS3A-DD-LV is able to dim the lamps
using DALI/DSI, the product provides a facility to disable this for a given period of time.
Operation
By setting the "Burn in" parameter, you can select a time during which the lamps are not allowed to deviate from
maximum output. The unit counts the time, and even remembers how long has elapsed in the event of a power failure.
To cancel the burn in function, simply select a time of 0. Note that when the lamps are changed, the burn in time should
be set again.
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.
