Choosing a Suitable Location
The EBDSPIR-AD 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.
Installation
Detection Mode
The Detection Mode for both output Channels 1 and 2 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.
Maintained Illuminance (daylight harvesting)
The detector measures the overall light level in the detection area and calculates the correct output for the luminaires, to
achieve a preset lux level (maintained illuminance or daylight harvesting).
Sensor functionality
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 EBDSPIR-AD is able to dim the lamps
using 1-10V, 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.
