MLS Digital Detectors with photocell
D MLS2001AF / D MLS2001ASM
for use with Analogue 1-10V ballasts
Important installation information!
Installation and commissioning may only be done by an authorised
electrician. Mains power (230V~/50 Hz) to electrical equipment must
be switched off during installation. Applicable laws and standards of
the country in which the device is operated must be observed!
MLS Digital Detectors are the high-performance, communicating,
presence detectors which lie at the heart of the advanced lighting
management system known as The PEHA MLS Digital. These
detectors are equipped with a regulating photocell to work with
analogue 1-10V ballasts.
Fixing
D 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.
D 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
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 out-
put 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 below.
