'OneSwitch' Dimming
OneSwitch dimming affords local control to the end-user whereby
a simple, momentary, push-to-make wallswitch can be used to
raise or lower the lighting level or to toggle the output ON/OFF. A
short press of the switch (less than 1 second) will toggle the out-
put status while a longer press will raise or lower the output. Each
time the switch is pressed, the direction of dimming reverses. If the
switch has not been pressed for 5 seconds, the direction will be up
(brighter) - unless the output is already above 90% in which case
the direction is down. If the switch is held continuously, and the
output reaches maximum, the light output will remain at this level
until the switch is released - a latching switch may be connected
in parallel allowing the occupancy detection to be overridden on
(Note: If the initial direction was down, when the output reaches
minimum it will ramp back up automatically). A wiring diagram is
shown above.
Commissioning
Detectors are supplied factory pre-set which ensures the lighting will
switch on automatically as soon as power is applied. Final commis-
sioning of the detectors, including assigning to zones, requires the
use of the D HP2000 Programmer.
Please read carefully the operating instructions that accompany the
programmer prior to performing a programming operation.
Commissioning Detectors using the D HP2000
1. Switch on D HP2000 by pressing the red power button.
2. Point D HP2000 at detector and press the DOWNLOAD button.
The D HP2000 will confirm the product's identity and call up the
correct menu of parameters and their current settings.
3. Use a combination of UP, DOWN, FORWARD and BACK buttons
to navigate the parameter menu, selecting options for each
shown. (See Tips below.)
4. When options for all parameters have been selected, point the
D HP2000 at the detector and press the UPLOAD button. The
luminaire(s) will switch off briefly during the programming pro-
cess and the D HP2000 shows DATA OK to confirm operation.
5. After a short period of inactivity (default 5 minutes), the D
HP2000 hibernates retaining the most recent settings..

Tips
I. Where there are only two options such as ON/OFF, a double
click of the OK button toggles between them.
II. Where there are multiple options, a double click of the OK button
recalls a list of all options for that parameter. Use the UP, DOWN
and OK buttons to select.
III. Use the OK button to go forward (through the menus) without
displaying help pages.
IV. Press UPLOAD at any time to transfer all current settings from
the handset to the product.
Setting the Regulating Photocell
This product is intended for use with high frequency regulating
ballasts with digital control inputs. An infrared programming tool
D HP2000 or D HP10 is required for programming the regulating
light level set point. The setting is preserved in the event of a
power failure and can be re-programmed any number of times.
Using the D HP2000 MLS Programmer, enter the Utilities menu
and select 'Set Light Level'. Use the 'up' and 'down' buttons to
manually adjust the light output from the luminaire(s) and when
at the required level press and hold 'OK' to store. The luminaire(s)
will blink to acknowledge a successful store operation.
Important Additional Notes
1. All terminals on this product are provided for final connections.
It is not intended that the product be used as a junction box for
looping cables.
2. A means for disconnection must be incorporated in the fixed
wiring in accordance with the current wiring regulations.
3. Although nominally 12V, the dimming output is not SELV and
therefore should be treated with the same respect as mains with
regard to wiring practice. The 0V line of the dimming output is
almost at Neutral potential.
4. The dimming control output should be connected only to the
control input of the ballasts - never to other detectors.
5. This equipment should be used to control only those ballasts
powered from the same phase as the detector.
6. Due to the fact that the photocell is on the ceiling looking down,
it is not possible for measurements made with a lux meter on
the working plane to remain constant when daylight illuminates
the ceiling and the working plane to a differing extent. Therefore,
products of this type should be regarded as capable of maintai-
ning an APPROXIMATE light level only.
