MP2000UF
Universal Photocell
for Digital DSI, Digital DALI, Analogue1-10V
and non-dimmable ballasts
Parameter
Ballast
Selects ballast type (referred to as ‘Mode’ in this document).
Power Up
Modes affected: NON DIM only
If set to Auto, a light measurement is taken to determine
whether lights need to be switched on.
PCT (Passing Cloud Timer)
Modes affected: NON DIM, others if BRIGHT-OUT = YES
If the light level has been continuously higher than SET
POINT H (or lower than SET POINT L) for longer than the
duration of the Passing Cloud Timer the relay output will
switch off (on). If the level was not continuously higher than
SET POINT H or lower than SET POINT L then the PCT will
be refreshed.
PCT
In Asymmetrical mode the lights will switch on as soon as the
light level drops below the lower threshold (SET POINT L)
In Symmetrical mode the light level must be continually lower
than the SET POINT L value for the duration of the PCT
before the output will switch on.
Start Lamps
Modes affected: DSI, DALI & 1-10V
Dimming
Modes affected: DSI, DALI & 1-10V
100% = Regulate over the full range of the ballast’s capability.
Other % = Regulate within the stated percentage of the
ballast’s capability. (With 90% selected, the photocell will not
dim the lights to less than 10% output. With 80%, lights will
not be dimmed below 20% and so on.)
Bright-out
Modes affected: DSI, DALI & 1-10V
12Hr Reset
Modes affected: ALL
If set to YES and the unit is overridden using an HC6 Hand-
held Controller it will return to normal operation after 12 hours
or immediately if power supply interrupted.
If set to YES and the light level has been greater than the
value stored in Set Point H for the duration of the PCT, the
output will turn off. The output will turn back on immediately
when the light level falls to the normal regulating level stored
in Set Point L.

Parameter
Set Point L
Modes affected: ALL
This is the regulating set point. In NON DIM mode it is the
lower threshold. This is not a Lux value - it is a representation
of the Lux level at the time of programming.
Set Point H
Modes affected: ALL
This is the upper threshold.
This is not a Lux value - it is a representation of the Lux
level at the time of programming.
Set Light Level
Modes affected: ALL
See Commissioning
Request Download
Following a successful download, the number of perceived
light level units prior to the lights being turned off is shown on
the display. If the lights were already off then the perceived
level is the ambient light level.
In regulating mode with BRIGHT
OUT set to YES, this is the value at which the output will turn
off.

At the end of their useful life
the packaging and product
should be disposed of via a
suitable recycling centre.
Do not dispose of with normal
household waste.
Do not burn.

Installation
This photocell is suitable for flush fitting to a suspended ceiling of thickness up to
54mm. If it is to be fitted into a plasterboard ceiling, a PB64 (Plasterboard Fixing
Kit) should be used - contact Ex-Or for details.
A minimum clearance of 125mm is required between the front surface of the
ceiling tile/plasterboard and the end of the ceiling void.
Choose a suitable mounting location; ideally this would be within the area of the
controlled lighting at the furthest point from all sources of natural light.
Note: Do not mount within 0.25m of a luminaire.
To mount in a suspended ceiling, cut a hole in the ceiling tile using a 50mm hole
saw. Feed the MP2000UF into the hole and secure in position with the locking
ring.
For plasterboard mounting please refer to the dedicated PB64 installation
instructions.
Connection
Connect the MP2000UF in accordance with the diagram below observing the
following:
This equipment must be installed only by a suitably qualified person.
A means for disconnection must be incorporated in the fixed wiring in
accordance with the current wiring regulations.
Although nominally 12V, the dimming output is not SELV, and as such,
should be treated with the same respect as mains with regard to wiring
practice. The 0V line of the dimming output is connected internally to the
Neutral supply.

Commissioning - Dimming Photocell
The light level should be set using an HP2000. Select the ‘Set Light Level’ menu
item and adjust the light output of the luminaire to the approximate required lux
value using ‘Up’ and ‘Down’ as necessary. Once the correct light level is
achieved press ‘Send’ to store that level. See flow-chart.
Commissioning - Switching Photocell
Commissioning should be carried out at the time of day when the ambient light
level is near the desired switching level. If this is not practical, the desired light
level can be created by opening/closing curtains/blinds and by turning
uncontrolled luminaires on or off as required. Pressing SEND on the HP2000 will
store a snapshot of the light level.
There is a green LED on the front bezel to aid commissioning in Non-Dim mode.
The LED will be on when the MP2000UF requires more light. This is useful
because the relay may not be responding instantly to light level requirements
due to the passing cloud timer.
Note
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 different
extent. Therefore, products of this type should be regarded as being capable of
maintaining an APPROXIMATE light level only.
Light levels should be measured using a lux meter and commissioned at table
height, preferably without daylight contribution (i.e. at night).
After commissioning has taken place, the values stored in Set Point L and Set
Point H can be adjusted using the HP2000 if required. Please refer to the flow-
chart below and the default parameter values overleaf for further commissioning
information.

ImportantAdditional Notes
1. The dimming control output should be connected only to the control input of the
ballasts - never to other detectors.
2. This equipment should be used to control only those ballasts powered from the
same phase as the detector.
3. 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.
