CDH4U5

4-Channel Programmable

Intelligent Lighting Control Module

Installation and Commissioning Instructions

Introduction

The CDH4U5 is an intelligent LCM providing connections for multiple
luminaires*, up to 5 presence detectors and up to 5 SELV inputs. The product
simplifies installation whilst providing an intelligent lighting control system.
Provision is made for 4 volt-free power outputs rated for 415V isolation.
Additionally, the unit features a switched output for Maintained Live to allow
initiation of Emergency Lighting Test. The CDH4U5 has the ability to operate
from dual supplies with the capability to modify its operating behaviour when
failure is detected on one of the supplies. This feature is described in greater
detail in application note AN4027.

*Note: Refer to Technical Data section to find out maximum allowable number
of luminaires.

Electrical Connections

The connections to this equipment should be made only by a suitably
qualified person and in accordance with the current wiring regulations.

A means of disconnection must be incorporated in the fixed mains
wiring to this box in accordance with the current wiring regulations.

All the connections should be routed ensuring adequate strain relief on the
cable before termination to the unit’s pluggable connectors.

CAUTION: DO NOT CONNECT MAINS TO THE MLS BUS OR DIMMING
OUTPUTS.

should comply with EN 60715.

Connecting the Luminaires

Variants of the CDH4U5 are provided to control DSI, DALI and 1-10V ballasts. (See Part Numbers section for more details.)

Note: Dimming ballast types CANNOT BE MIXED on a single CDH4U5.

The CDH4U5 is equipped with 4 two-wire pluggable terminals for dimming outputs, 2 three-wire and 2 two-wire pluggable terminals for volt-free outputs.
The CDH4U5 has provision to connect more than one supply from different phases in three different scenarios: a) Single Supply, b) Essential and non-essential

supplies and c) Two supplies equally likely to drop out .

As shown in the diagram above, two equal supplies may be connected from a single phase or different phases. In order to maintain constant supply to the unit an
external change-over contactor* is required. Line terminals from each of the supplies (N1, L1 and N2, L2) are connected via the change-over contactor. The
Live and Neutral outputs from the contactor are connected to the mains input of the unit. In the case of failure of one of the supplies, the change-over contactor
switches to the alternative supply to ensure continuous supply to the unit. As shown in the diagram above, one or more channels may be wired to run from either
supply.

* Such as Lovato BG series mini-contactor.

Note: Please refer to AN4027 for recommendations on wiring supplies to the change-over contactor and part number.

Channel 1 & Channel 4 are equipped with three-wire pluggable terminals with provision of connecting Neutral and Live from each supply. On detection of supply
failure on Channels 1 or 4, the unit enters into special operating mode. During this mode, the unit controls the output of luminares connected to the channel(s)
fed by the remaining supply according to the settings of Scene 5. During this special operating mode, the unit will continue to respond to switch inputs and
occupancy detection. The unit automatically reverts to normal behaviour once the failed supply has been restored.

Note: Please refer to the Commissioning section for programming the channel output settings of Scene 5.

Connecting Presence Detectors

2

The following SELV detectors are designed to interface to the CDH4U5:

MLS2500CDR Corner-mount Microwave presence detector with photocell, semi-flush mounted. Available with surface mount (SM suffix).
MLS2401CDR 360° Microwave presence detector with photocell, flush mounted. Available in surface mount version (SM suffix).
MLS2001CDR 360° PIR presence detector with photocell, flush mounted. Available in surface mount version (SM suffix).
MLSM2002CDR Controller for a 360° PIR detector with photocell. Used with the DHS OR DHW mini-head to form an integral luminaire-mounted unit.
Each connects to the CDH4U5 by means of an Ethernet-style RJ45 connector terminated patch lead which are available ready-made in 3m, 5m and 10m

lengths. Up to five detectors may be connected to a CDH4U5.

Positioning Presence Detectors

For information on installing and positioning detectors, please refer to the installation instructions provided with the particular detector.

Connecting Switches

The CDH4U5 is equipped with SELV switch inputs which will typically be two way, centre off, momentary rockers, (e.g. the MK K4900 range). The logical
function of a switch can be configured from a wide range of options and its action can be associated with any combination of channels. The switch connection
consists of a 3-pole pluggable terminal block comprising a common and two returns from normally open contacts. Four plugs are provided with each CDH4U5,
additional plugs can be ordered using the code CDHIP (5 pieces per pack).

.

Note that if the SELV status of any one of the switches
is compromised by reason of inadequate insulation or
segregation of the cabling, then the SELV status of all
other switches AND OF THE DETECTORS will also be
compromised.

A

Com

B

The recommended cable for use with the SELV switches is 3-core 300/500v 0.75mm² cable to CMA Reference 3183Y or for LS0H, to CMA Reference 3183B.
The maximum allowable cable length between the switch mechanism and the CDH4U5 terminal block is 100m.

Three separate single wires should not be used.

Connecting the Communications Bus (MLS)

It is imperative that the MLS Bus be wired in the correct type of cable. Normally it should be 1.5mm unscreened twisted pair. See Application Note AN4001.

Do not connect Mains to the MLS Bus.

* Planned

The LCM is commissioned using a dedicated programme running on a Windows-based computer. Commissioning settings may then be directly uploaded from
the computer to the LCM or transferred to an HP2000 hand-held programmer for easy upload on site.

Communication from the PC can be by means of a USB infrared transceiver which can signal directly to the LCM’s on-board infrared port over a short range or via
any attached presence detector from beneath (range: 1-3m).

The main parameters for configuration are tabulated below. These parameters may be re-programmed any number of times and all settings will be retained in
the event of a power loss.
