MLS2001AF & MLS2001ASM - MLS Digital Detectors for use with Analogue 1-10V 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 detectors are equipped
with a regulating photocell to work with analogue 1-10V ballasts.
Fixing
MLS2001ASM - The housing may be secured to a hard surface or a BESA box. The unit fits into the housing
with a simple bayonet action.
MLS2001AF - 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.
Note: Do not mount within 25cm of a luminaire.
Connection Overview
Each luminaire to be controlled must contain an analogue regulating type ballast with the appropriate analogue
input. Ballast types must not be mixed. Connect all ballasts in the control group (maximum load 6 Amps) in
parallel and also to the analogue output of the MLS Detector.
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
2
twisted 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 above.
Setting the regulating photocell
This product is intended for use with high frequency regulating ballasts with analogue 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 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.
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 button. The luminaire(s) will switch off briefly during the programming process.
5. After a short period of inactivity (default 5 minutes), the programmer hibernates retaining the most recent
settings.
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.
