MLS Digital Detectors: MLS2001DF/SM for DSI ballasts & MLS2001DALIF/SM for DALI ballasts

Note: Connections to this equipment should be made by a suitably qualified person and in accordance with the
current wiring regulations.

MLS Digital Detectors are the high-performance, communicating, presence detectors which lie at the heart of the
advanced lighting management system known as The Ex-Or MLS Digital. These MLS Detectors are equipped with a
regulating photocell to work with digital DSI/DALI ballasts.

Fixing

Flush Versions: Depth required behind ceiling: 62mm from front flange plus an allowance for the minimum bend radius
of the cable. The sinking box fits into a 89mm diameter hole in ceiling tile or plasterboard ceiling. To avoid damage to
ceiling tile, do not overtighten. No access above the ceiling is necessary.

Surface Versions: The housing may be secured to a hard surface or a BESA box. The unit fits into the housing with a
simple bayonet action.

Note: Do not mount within 25cm of a luminaire.

Connection Overview (see last page for diagram)

Each luminaire to be controlled must contain a digital regulating type ballast with the appropriate DSI or DALI input.
Ballast types must not be mixed. Connect all ballasts in the control group (maximum 25) in parallel and also to the
polarity-free digital output of the MLS Detector.

Each luminaire is controlled completely by its digital input and therefore would normally have a permanent power supply.
Turning the power off to some lights within a control circuit will not affect the operation of those that remain powered-up.

The MLS Bus must be connected to the MLS bus wiring network. An MLS Bus Power Supply is required for each
network of up to 200 MLS Detectors. Please refer to Bus Power Supply installation instructions prior to commencement
of any bus wiring.

It is imperative that the MLS bus is wired with the correct type of cable; normally it should be 1.5mm unscreened twisted

2

pair. Please read Application Note AN4001 for more details. Do not connect mains to the MLS bus.

‘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 output 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 on the last page.

Setting the Regulating Photocell

This product is intended for use with high frequency regulating ballasts with digital control inputs. An infrared
programming tool QuickSet Pro 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 QuickSet Pro, enter the Utilities menu, select ‘LightSpot/MLS/LCM’ then ‘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.

Commissioning

Detectors are supplied factory pre-set which ensures the lighting will switch on automatically as soon as power is applied.
Final commissioning of the detectors, including assigning to zones, requires the use of the QuickSet Pro Programmer.

Commissioning Detectors using the QuickSet Pro

It is important that the Programmer be held perpendicular between 0.5m and 2m from the sensor.

1. Switch on by pressing any button (and unlock with top left rectangular button).

2. Point the programmer at detector and press the DOWNLOAD button. The programmer 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.

4. When options for all parameters have been selected, point the programmer at the detector and press the UPLOAD

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 maintaining an APPROXIMATE
light level only.
