The following wiring diagrams show how to connect some of the more
fully-featured products listed in the product table above. For clarity, the wiring
for some of the lesser-featured products is not shown, but the wiring principles
are the same and equally applicable. Simply omit any sections that are not
relevant to the product being installed.

Analogue ballasts cannot be switched off from the control terminals, so it is
necessary to switch the mains power from the sensor as shown in the diagram
below. Although switching the mains power is not necessary with digital ballasts,
they may be wired this way in order to reduce the quiescent power consumption
to an absolute minimum.

Bus (fig 4)
The diagram below shows how to connect a low voltage photocell to the
QuickLink bus. In this example, the QuickLink bus is powered by a mains
powered presence sensor.

Mounting (optional)
Product variants with “SM” suffix
on the part number are supplied
with the surface fitting kit as
standard. The surface mount kit is
available as a separate part,
please order Surfmt.
The sensor may be mounted to
any suitable surface, but is most
commonly fixed to a conduit
stop-end (fig 5 set) (BESA) box or
bushed to trunking.
See fig 1 for
connections
Uninstalling and Repositioning
Insert a flat headed screwdriver into the
slot as shown and twist the collar
anti-clockwise to release,
To separate the sensor from the surface
mount casing, push a flat headed
screwdriver onto the tab via the inside void
of the casing and pull the sensor
upwards,

Diagnostics
A number of LED indications are provided in order to help with fault-finding.
Sensors are supplied with the LEDs disabled, however they may be enabled
at the point of commissioning if required. Detectable wiring faults are always
indicated by the LEDs, irrespective of whether they are enabled.
Wiring faults on analogue dimming circuits are difficult to detect automatically.
If analogue dimming is not working as expected, the recommended method
for checking is as follows:
1. Disconnect the dimming control pair from the sensor.
2. With the [now open-circuit] dimming control wiring still connected to the
luminaires, the brightness should immediately go to full.
3. Briefly short together the two wires from the luminaire dimming pair, the
luminaires should go to low brightness, but not off.
4. If either of steps 2, 3 above do not work as described on every luminaire,
investigate the wiring. When working correctly, re-connect the dimming
pair to the sensor.

IMPORTANT NOTES
1. A means for disconnection must be incorporated in the fixed wiring in
accordance with the current wiring regulations.
2. Dimming (DALI, DSI and Analogue) and QuickLink terminals have only
basic isolation from mains and therefore should be wired in mains-rated
cable and treated with the same respect as mains with regard to
wiring practice.
3. This equipment is designed to switch lights no more frequently than
normal manual operation. However, manufacturers of some particular
lighting types (e.g. '2D' luminaires) may specify a maximum number of
switching cycles and/or a minimum on-time 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.
Out of Box Behaviour
Prior to commissioning, the default settings for each channel of the
sensor will be as follows:
Time Delay: 20 minutes
Photocell Setting: Always turn lights on
Dimming Level: 100%
Occupancy Mode: Automatic (lights Auto ON, Auto OFF)
Digital Ballast Type (DSI/DALI): Auto detect
NOTE: Please go to www.ex-or.com for a complete list
of programmable parameters.
4. In order to achieve satisfactory light level regulating operation, a sensor
must observe a substantially greater proportion of artificial light from the
luminaire(s) under its control than from neighbouring luminaires not under
its control. This is particularly important when planning the installed layout
of linear luminaires that have an integral detector positioned at one end.
5. Due to limited space within the enclosure, it is not recommended that this
product be used as a wiring junction box. System connections should be
made elsewhere and wiring not looped within the product enclosure.
