CP Electronics UNLCDHS - LUX Control (Ch 1 & 2)

21
UNLCDHS Programming – LUX Control (applies to both Ch. 1 & 2)
Basic Parameters for all models including ‘-PRM’, ‘-PRM-2CH’, ‘-DD/SR’ and ‘-AD’
Parameter Default Range / Option Description
Light Level (MI) 999 1 – 950 (999
= maintained
illuminance o)
Sets a target light level to be maintained by the lighting system.
(The maintained illuminance is not applicable to ‘-PRM’ products)
For version V3 sensors, limit the target LUX setting to within 950 LUX which when
mounted on the ceiling would equate to around 1900LUX on desk level for a reectance
factor situation of 0.5. For versions previous to V3, limit the target level to within 300
which would equate to 560 LUX on the desk under the same reectance conditions.
LUX Learn Level
(V3)
0 0 – 950 Use with the Readback function to get the LUX level the unit is currently reading.
Press Send to update the Light Level (MI) parameter with this value.
Auto Brightness %
(V3)
0 0 – 100 (0 = disabled) Instead of setting LUX ON and OFF as individual parameters, Auto brightness sets
these parameters as the assigned percentage of the LUX learn level.
(The maintained illuminance is not applicable to ‘-PRM’ products)
LUX On Level 999 1 – 9 (V2)
1 – 950, 999=disabled
(V3)
Sets the light level below which will turn on the output in conjunction with
movement control. The output will turn on without movement should the Disable
Detect parameter be set to YES.
Value 9 (V2) or 999 (V3) disables both LUX ON and LUX OFF functions.
The LUX O Level value must always be greater than the LUX On Level value.
LUX O Level 999 1-9 (V2)
1 – 950, 999=disabled
(V3)
Sets the light level above which will turn OFF the output in conjunction with
movement control.
Value 9 (V2) or 999 (V3) disables both LUX ON and LUX OFF functions.
The LUX O Level value must always be greater than the LUX On Level value.
LUX Time (V2) 0 0 (disabled) 1 – 99 mins If the detector measures the LUX level and decides that the output needs switching
on or o as a consequence, the LUX time must elapse rst. If at any time during the
timed delay the LUX change reverses then the process is cancelled.
LUX Time enables absence detection to be implemented with a LUX o level set.
When the button is pressed, the lights will go on, regardless of ambient light level.
However, if there is sucient ambient light, they will turn o again aer the LUX
Time.
Note: Whenever the an external switch is pressed, whether in absence or presence
mode, if the lights were out because of the LUX level, they will be immediately
turned on again for at least the LUX Time.
LUX On Time
(V3)
0 0 – 99 minutes When the ambient light falls below LUX ON Level, the time to wait before switching
on the lights. If at any time during the timed delay the LUX change reverses then the
process is cancelled. Minimum time of around 15 seconds is set for a value of 0.
If you try to turn lights on using a switch or handset, the lights will go on regardless of
ambient light level. However, if there is sucient ambient light, they will turn o again
aer LUX O Time.
LUX O Time
(V3)
0 0 – 99 minutes When the ambient light rises above LUX OFF Level, the time to wait before switching
o the lights. If at any time during the timed delay the LUX change reverses then the
process is cancelled. Minimum time of around 15 seconds is set for a value of 0.
LUX Switch NZOL
(V3)
No Yes / No For future use. Leave “No”
Note: Certain parameter functions are only available in specic versions of the detectors and these are indicated under the aected parameter headings
within the brackets e.g. LUX Learn Level (V3).
