MLS Digital Local Control Plate

MLSLCP4 MK2

for use with the MLS Digital range

Installation and Commissioning

Instructions

General Installation and Operation

The MLSLCP4 should be mounted on the supplied single-gang
sinking box supplied. When mounting ensure that the orientation
information on the plate is followed. Ensure that the mounting frame
and the metallic fascia plate are bonded to the building Earth grid via
the Earth terminal block provided on the mounting frame.

The MLSLCP4 Local Control Plate is designed to operate as part of an
MLS Digital installation. This device sends messages to other
equipment that is actually in control of the lights. It provides simple,
manual control over a group of light fittings programmed to the same
zone address, allowing the end-user to select one of three pre-set
scenes, to dim, brighten or switch off the lighting as required.

The MLSLCP4 also allows brightness control; this is initiated by a
long press on Button 2 (brighten) or Button 3 (dim). To facilitate
minor adjustments of the light level, the MLSLCP4 remains in
manual mode for a few seconds, allowing momentary presses of the
dimming buttons. The buttons revert to scene-selecting mode after
the short time out.

The MLSLCP4 will control the lights programmed to its zone only.
This is set via an 8-way dil switch on the reverse of the unit as in the
following diagram. Each switch has a value - 1, 2, 4, 8, 16, 32 and
64 (the switch designated ‘Mode’ should remain OFF). Using a
combination of these will allow any zone to be set from 1 - 100.

The MLSLCP4 connects directly to the MLS bus via the terminals
located on its reverse. 1.5mm mains-rated unscreened twisted-pair

must be used for this connection, however if just a short spur is
required to the plate then single cables may be used. Polarity must
be maintained throughout.

Commisioning

Adding together the value of

ONON

switches 1-7 that are set to
‘ON’ sets a Zone number for
the con tr ol p l a t e . T hi s
diagram shows values 2 and
16 set to ‘ON’ and therefore
denotes Zone 18.
