Commissioning
The units are supplied with the factory default settings shown below which
render commissioning unnecessary in many applications. To make use of the
programmable settings, an infrared commissioning tool is required (HP2000).
Aten-second "Walk Test" time delay is selectable to aid commissioning
Factory Default Settings
These are the settings to which the units have been programmed before they
leave the factory.
Gold Series LightSpot for use with Analogue 1-10V Ballasts
Only suitably qualified personnel should install this equipment.
This high-performance presence detector forms a stand-alone lighting control
unit. It is equipped with a regulating photocell to control analogue 1-10V
ballasts (when using the detector’s Dimming Output) and a volt-free output to
fully extinguish analogue dimmable loads or for control of non-dimmable
lighting loads. The detector incorporates Ex-Or’s OneSwitch Dimming,
allowing local manual operation of any controlled lighting load.
Electrical Connections
The detector should be connected in accordance with the diagrams opposite.
Each luminaire to be controlled must contain an analogue regulating type
ballast with the appropriate analogue input. Ballast types must not be mixed.
The analogue input terminals on the ballasts should be connected in parallel
with each other and to the analogue 1-10V output terminals on the rear of the
detector, observing the polarity. Also each of these analogue regulating
ballast Live inputs (maximum load 6 Amps) must be provided by the Volt-free
output (see 1st Wiring Example) from the detector.
When switching via the volt-free output multiple MS2421A detectors may be
connected in parallel provided the controlled load does not exceed 6 Amps.
(see 3rd Wiring Example).
DO NOT CONNECT DIMMING OUTPUTS TOGETHER .
OneSwitch
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 toggle the output of the unit ON or OFF. A short press (less than
1 second) toggles the relay output from OFF to ON or from ON to OFF. A long
press will ramp the analogue output either up or down with no effect on the volt-
free output. If the output prior to pressing the switch is above 90% the output
will ramp down; if below 90% it will ramp up. If the latest press and the current
press are within 5 seconds of each other it will ramp in the opposite direction.
Sensitivity to Movement
While the factory settings will be correct for many applications, the sensitivity
can be adjusted if required.
ON Sensitivity (ON Range): This sets the detector’s range when the lights are
ON. (i.e. the space is Occupied) Choose setting from 1-100 where 1 is lowest
and 100 is maximum. (Note: Choose the lowest level possible to give
adequate detection.)
OFF Sensitivity (OFF Range): This sets the detector’s range when the lights
are OFF. (i.e. the space is Unoccupied/Vacant) Choose % setting from 10% to
100% where 10% = 10% of ON Sensitivity and 100% = same as ON Sensitivity.
This is an approximation and should be tested on site during commissioning.
Generally the OFF Sensitivity should be significantly less than the ON
Sensitivity as in the ON/Occupied state small movements of e.g. seated
persons must be detected while in the OFF/Vacant state only the gross
movements of persons entering the space need to be detected. This
differential sensitivity prevents false triggering of the Presence Detection logic.
Like all programmable parameters, the sensitivity settings will be retained in
the event of a power failure and can be re-programmed any number of times.
Commissioning the Photocell
Commissioning the setpoints for Photocell based control requires the HP2000
Hand-held Programmer.This tool should be used aimed squarely at the front of
the Detector/Photocell at a distance of 1m although it can work at substantially
greater distances if aimed carefully.
Regulating Only: For this mode the PCELL RLY action should be set to
“DISABLED” and the lights will be on continuously during periods of
occupancy. The Analogue 1-10V output dims the ballast(s) in the luminaires.
It always tries to maintain a programmed light level on the working plane. It
aims for the level stored in the parameter Set-point Low.
Sometimes it is convenient to limit the extent to which the presence detector
with photocell is allowed to dim the light output of the luminaire(s). This can be
done by setting the "DIMMING" parameter. This setting determines the range
over which dimming can be operated e.g. setting 80% allows the lumiaires to
be dimmed down to a minimum of 20% of its possible output as natural light
strengthens.
If it is desired to operate the lighting without any automatic photocell based
control over the dimming process, (e.g. only manual control of dimming, by
OneSwitch, and/or scene setting by HC5 Infrared Hand-held Controller is
required) then the default values of 1023 should be retained in the parameters
Set-point Low and Set-point High.
Programming the Regulating level: Place a light meter on the working
plane underneath the presence detector with photocell. Adjust the light output
of the luminaire up or down manually by infrared. (On the HP2000, select
“UTILITIES” from the Main Menu and then “SET LIGHT LEVEL” from the
UTILITIES Menu. The up and down Arrow keys allow adjustment of the light
level up and down whilst pointing the handset at the presence detector with
photocell.) When the light meter reads the desired level, press and hold the
central “OK” button until the lights “blink” to acknowledge that the

it be installed on a rigid surface that will not itself be subject to movement or
vibration.
Please note that microwave detectors are not recommended for applications
where there are large surface areas of metal, e.g. metal ceiling or floor tiles, as
unpredictable sensitivity may result.
The units are graded according to four variations in operating frequency. Each
type can be identified by different colour-coding on the detector label and
carton. For reliable operation it is essential that units of the same colour code
do not occupy adjacent positions in open-plan areas or in adjoining rooms (see
below).
is an extremely sensitive movement detector; it is essential therefore that
Note: Should it be necessary to order additional detectors for an existing
installation and specific colour-coded detectors are needed, please add the
following suffixes to the part number: Y = Yellow, B= Blue, G= Green, R = Red.
(There is normally no need to specify the colour codes, as orders are
dispatched with a suitable colour code mix.)

User Overrides
The end-user can configure a number of lighting scenes that can be recalled
using a hand-held override. With an HC5 hand-held controller lighting can be
overridden OFF or ON, or a set level can be chosen. Regulating and switched
loads can be adjusted independently through a combination of OneSwitch
Dimming and the HC5 Hand-held Controller.

photocell reading has been stored in the Set-point Low parameter. This is the
control set-point for the regulating process which tries to maintain this
photocell reading at all times by dimming or brightening the lights.
Switching the Lighting Load:
In addition to dimming the lighting load via the 1-10V output, the load can also
be controlled by the relay according to natuiral light level.This form of control is
governed by the setting of the parameter PCELL RLY. There are three options
for this parameter:-
DISABLED: In his mode the photocell has no effect upon the operation of the
relay - it will switch only according to detected occupancy.
PASSIVE: In this mode the relay will be inhibited from closing if the area is
entered when the ambient light level is above Set-point Low. If during the
period of occupancy, the light level falls below Set-point Low, then the lights will
switch on. In this mode the lights will never switch off during a period of
occupancy - no matter how bright it becomes.
ACTIVE: This is the same as PASSIVE mode except that, additionally, the
lights will switch off if the light level exceeds Set-point High even if the area is
occupied. For the switch-off to occur, the light level must persist at this high
level for the full duration of what is called a "Passing Cloud Timer" (PCT). The
PCT is usually of the same duration as the Off-delay used by the Presence
Detection logic; however when an unusually long Off-delay is configured the
PCT is automatically capped at 20 minutes. If the light level falls below Set-
point Low during a period of occupancy, then the lights are switched on
immediately without any delay.
Programming the Set-points:
1) Simple PCELL RLY Switching Control:
i) If PCELL RLY-ACTIVE switching action is required it is important that the
lights are switched on at least 15 minutes before this procedure is undertaken
to allow the tubes to reach full output. For PCELL RLY-PASSIVE switching
action this is not necessary.
ii) Download the settings already established within the Detector for non-
Photocell related features to the HP2000. Edit the Photocell setting to ACTIVE
or PASSIVE as required. Upload the whole configuration to Detector.
iii)Wait until the appropriate time of day for, or use blinds to create, the natural
light level, as measured with a light meter, below which you would want the
lights to be on and above which you would not want the lights to be on.
iv) Start the internal self-programming operation by selecting UTILITIES/SET
LIGHT LEVEL on the HP2000 and pressing and holding the "OK" button. The
Detector takes a Photocell reading, adds a small margin and stores the
resulting value as Set-point High. It then switches off the controlled lights and
takes another Photocell reading which it stores as Set-point Low. The lights
are now switched on again, completing the acknowledgement "blink". The OK
button can now be released. Note that the difference between the two Set-
point values, the Switching Hysteresis, is equal to the contribution to total light
made by the controlled luminaires. This is the ideal amount of hysteresis to
prevent oscillation without compromising control accuracy.

2) Regulating Control overlaid by PCELL RLY Switching Control
First carry out the commissioning procedure described for Regulating Only
control (under Photocell Commissioning). When the Regulating Only
commissioning procedure has been carried out the HP2000 parameter Set-
point Low within the Detector has acquired a new, non-default value. This value
should be read in a full download from the Detector to the HP2000 and retained.
The Set-point High value should now be manually edited on the HP2000 screen
to be about 25% higher in the same units, e.g. if a download from the Detector
to the HP2000 shows that 429 has been automatically stored into the Set-point
Low parameter, then the Set-point High value should be manually edited to 535
or 536. The PCELL RLY action should be set to “ACTIVE” or “PASSIVE”, as
required, and the whole configuration then uploaded to the Detector.

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. Ameans 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. 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 maintaining anAPPROXIMATE light level only.
6. This equipment switches lights no more frequently than would a responsible human occupant. However, manufacturers of some lighting types (e.g. ‘2D’
luminaires) may specify a maximum number of switching cycles in order to achieve a predicted lamp life. Please check with the manufacturer of the
luminaires to ensure that they are compatible with automatic controls in this respect.
7. The detectors are extremely sensitive to movement; they must be mounted on a solid surface which has no movement whatsoever.
8. This equipment should be used to control only those ballasts powered from the same phase as the detector.
