CP Electronics EBDSPIR-DD-LV - Manual (Page 2)

page 2
The EBDSPIR-DD-LV PIR (passive infrared) presence detector provides automatic control of low voltage
loads including lighting and BMS systems with optional manual control. It can be used to control DSI or
DALI dimming ballasts. The unit detects movement using a PIR sensor and turns the load on. When an
area is no longer occupied the load will switch off after an adjustable time out period.
The dimming channel of the detector can be used to control the light output of luminaires that are fitted
with dimming ballasts. 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).
The switching channel of the detector can either be used to isolate the supply to the dimming ballasts
(saving on the standby current of the ballasts) or to switch a separate channel of standard, non-dimming
luminaires.
Two input terminals can be used to manually override the dimming levels and override the load on or off.
The flexibility of having two channels and two switch inputs allows the following example scenarios:
1.
Dim an outside row of luminaires whilst internal fittings are switched
2. Provide absence detection (see below) for two separate channels
3. Maintained illuminance system with manual up/down controls
An integral infra-red sensor in the unit allows the unit to be programmed using the optional DD-LCDHS
programming handset. This gives complete flexibility over many of the operating parameters. Without the
handset, manual adjustments can be made to the sensitivity, lux and time settings using the controls on
the rear of the sensor head.
The UHS user handset can be used to change output lux levels and override the load on or off.
Two standard units are available:
EBDSPIR-DD-LV - presence detection:
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.
EBDSPIR-DD-LV/ABS - absence detection:
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. Note that the EBDSPIR-DD-LV can be programmed to
absence detection using the programming handset.
In most applications the EBDSPIR-DD-LV can be used with simple manual adjustment. However, the
EBDSPIR-DD-LV unit has a comprehensive set of features that can be set using the DD-LCDHS handset.
Alternatively the units can be commissioned as follows:
On-site commissioning service - please contact our sales department for details.
Pre-commissioning service - the units will be despatched to site with the correct features set. The
part number will read ―Product code‖/PRG followed by the project reference number. Please
contact our sales department for details.

LOAD DOES NOT COME ON
Check to see if the supply to the circuit is good.
If the supply and wiring are good, check the LUX level setting. Increase the LUX level setting to allow the
controller to turn on at higher ambient natural light level.
If the detection range is smaller than expected, check the diagram above. Rotating the sensor slightly may
improve the range.
LOAD DOES NOT GO 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.
