Product Item

This guide provides installation, setup and specification information for the LEDsmart+ Push Button Dimmer/Switch, item number MMDM/PB.

Product summary and capabilities

Designed in Australia to provide optimized dimming of LED based lamps and drivers, this high quality, two-wire phase control dimmer can be connected in parallel to other LEDsmart+ devices to provide a simple solution to multi-way control.
Although optimized for LED lighting loads, the dimmer also provides excellent compatibility with other common lamp types such as incandescent lamps, 12V halogen (dichroic) lamps and dimmable CFL’s.

Programmable setup functions

dimming levels, it can flicker or pulse on/off. The dimmer’s minimum brightness can be set to a level above the point at which a lamp flickers/pulses
Maximum Brightness| The maximum brightness level provided by the dimmer can be set to suit customer requirements
Kick Start| This function is only required when dimming some LED and CFL lamp’s. To ensure these lamps switch on, they require the dimmer output to be set to 50% for 0.2 of a second when the lamp is turned on.

Default: The Kick Start feature is switched off

LED indicators| The dimmer’s white LED indicators can be set to glow on or turn off when the dimmer is switched off

Default: The white LED indicators are set to glow on when the dimmer is turned off

**Separate Switch Mode***| Some lamps, such as non-dimmable CFL’s, can flicker when switched OFF using the dimmer’s integrated switch. In these cases, the dimmer can be used in ‘Separate Switch Mode’ and combined with a separate mechanical switch

Default: Separate Switch Mode is switched off

Toggle / Memory Dimmer| The dimmer has the option to turn on at the brightness level set when the lights were turned off (memory dimmer), or to turn on at the maximum brightness level (toggle dimmer).

Default: the dimmer is setup as a toggle dimmer

MultiMate™ ON/OFF| MultiMate™ functions can be switched ON or OFF

Default: MultiMate™ features are switched on

• Note: Separate Switch Mode is suitable for single LED smart+ installations only. For multi-way installations, see the note below.

There are a wide range of LED and CFL lamps available from different manufacturers. The following issues are occasionally seen when used in conjunction with 2-wire dimmer/timer/switch products.

• When switched off, the LED/CFL lights flicker, pulse on/off or do not switch off completely
• When switched off, the LED smart+ LED indicators flicker
• When switching on, the LED/CFL lights have difficulty switch on and the dimmer indicators flicker or pulse

It is recommended to install a Diginet ‘Load by-pass’ device (Diginet item number MMBP) across Load and Neutral terminals to provide improved performance of these lamps.

Multimate™ technology

MultiMate™ is a technology inside Diginet’s range of high quality LEDsmart+ dimmers, timers and electronic light switches. It allows multi-way control of lighting without the need for an expensive control system. MultiMate™ technology is suitable for both new and retrofit installations.
MultiMate™ technology enables multiple LEDsmart+ two-wire devices to be wired in parallel when two-way, three-way or multi-
way dimming and switching is required. When connected in parallel LEDsmart+ dimmers allow dimming (and switching) of connected lighting loads from multiple locations without any additional wiring. No strapper wires, dedicated remote switch wiring or ‘control bus’ is required.
MultiMate™ is a patented technology, developed in Australia by Gerard Lighting.
The wiring example below shows three LEDsmart+ dimmers connected in parallel to provide three-way dimming and switching of four downlights without any additional wiring.

Products with MultiMate™ technology included
The following products all include MultiMate™ technology and can therefore be connected in parallel to allow multi-way control. Note that different types of MultiMate™ products can be connected in parallel. For example, switches and dimmers can be connected in parallel to control the same group of lights from different locations and/or provide additional functionality.

Dimmer installation

WARNING – This product must be installed by a suitably qualified installer
Electric shock may result in serious injury or death. Follow all warnings in this guide and on the product while working in accordance with the latest electrical safety practices for mains-powered electrical equipment.

The terminal block included with the dimmer should be used to carry out the electrical connections, as shown below

Once the connections have been made, the terminal cover is closed to ensure the screw terminals are not exposed The terminal block can then be cable-tied to the rear of the dimmer housing utilising the two loop holes

Wiring for one-way dimming and switching

The dimmer has a built in tap on / tap off switch. Therefore, to provide both dimming and on/off control, no separate switch is required.

New Installation – one-way dimming and switching

Replacing existing one-way switch with one- way switching/dimming

Existing one-way switching Replacement one way dimming/switching

Wiring for two-way dimming and switching

To achieve two-way dimming and switching using LEDsmart+ dimmers, the two dimmers are connected in parallel. Note that the dimmers have an integrated switch, therefore no separate switches or additional strappers are required for two-way on/off control.

New Installation – two-way dimming and switching

Two-way dimming and switching using LEDsmart+ dimmers. Note the two-wire dimmers are simply wired in parallel.

Replacing existing two-way switching with two-way dimming/switching
When replacing existing two-way switching with two-way dimming/switching using LEDsmart+, the existing two-way ‘strapper’ wires can be re-used. No new wiring is required. See the wiring diagrams below.

Existing two-way switching

Traditional two-way switching using standard rocker switch mechanisms and scrappers between the switches.

Replacement two-way dimming/switching Rocker switches replaced with LEDsmart+ dimmers using the existing strapped wires. No new wiring required.

Wiring for multi-way (three-way or more) dimming and switching

To achieve multi-way dimming and switching using LEDsmart+ dimmers, the required number of dimmers can be connected in
parallel. Note that each LEDsmart+ dimmer has an integrated switch, therefore no separate switches or additional scrappers are required to provide multi-way dimming and on/off control.
The diagram below shows the required wiring for three-way dimming and switching using LEDsmart+ dimmers. If more than three-way control is required, further LEDsmart+ devices are simply wired in parallel.

New Installation – multi-way (three-way or more) dimming/switching

Existing three-way switching

Traditional three-way switching using two rocker switches and one intermediate switch, with stripers between the switches.

Replacement three-way dimming/switching

Rocker switches and intermediate switch replaced with LEDsmart+ dimmers. The existing stripers are used to connect the dimmers in parallel. No new wiring is required.

Rocker and flat push buttons

Two different styles of push buttons are included in the dimmer packaging, rocker and flat push button styles. These are interchangeable, depending on customer preferences.

Coloured Bezels
The dimmer’s LED indicators are white and the pre-fitted bezel provides a white glow around the dimmer button. Interchangeable blue, green and orange bezels rings are also included with the dimmer. These can be used to change the colour of the LED indicators to match customer colour preferences and/or to more easily identify different LED smart+ devices on the same grid plate.

Installing LED smart+ devices into Clipsal Saturn™ or Clipsal Saturn

Zen™ wall plates

Adaptor kits are available separately to enable LED smart+ devices to be installed into Clipsal Saturn™ or Clipsal Saturn Zen™ wall plates. Order codes are as follows.

Dimmer Setup

The LED smart+ push button dimmer has a number of useful functions which can easily be set up by entering setup mode and following three easy steps.

It is recommended that the MINIMUM BRIGHTNESS is always setup. The other settings are optional, depending on the dimmer application. To set the minimum brightness now, go to the next page.

Dimmer Setup Functions

A: Entering Setup Mode

If the dimmer has been powered up for LESS THAN 30 MINUTES see A1 below.

If the dimmer has been powered up for MORE THAN 30 MINUTES see A2 below.

Once in Setup Mode, options are selected by a series of ‘clicks’ of the dimmer push button. Each ‘click’ should be approximately 1 second after the previous click.

A1: Dimmer has been powered up via mains 240Vac for LESS THAN 30 MINUTES

Step 1 Press and hold the dimmer push button for 10 seconds
Note: Connected lights will dim up or down, this is normal

Step 2 The white LED Indicators will blink ON/OFF twice per second. This indicates that the dimmer is now in Setup Mode
Note: If more than one LED smart+ device is connected in parallel (see pages 5-7), all these devices will now enter setup mode. The blink ON/OFF will also be seen on all other LED smart+ devices connected in parallel.

Step 3 The dimmer is ready for the settings to be adjusted as required. Go to the relevant setup function instructions

A2: Dimmer has been powered up via mains 240Vac for MORE THAN 30 MINUTES

Step 1 Press and hold the dimmer push button for 30 seconds
Note: This resets the Setup Entry time back to 10 seconds (for the next 30 minutes) Note: Connected lights will dim up or down, this is normal

Step 2 The white LED Indicators will blink ON/OFF with twice per second. This indicates that the dimmer is now in Setup Mode
Note: If more than one LEDsmart+ device is connected in parallel (see pages 5-7), all these devices will now enter setup mode. The blink ON/OFF will also be seen on all other LEDsmart+ devices connected in parallel.

Step 3 The dimmer is ready for the settings to be adjusted as required. Go to the relevant setup function instructions

B: Setting Minimum Brightness

The minimum brightness level provided by the dimmer can be set to suit specific lamps and/or customer requirements.
For the majority of lamps a minimum level as low as 0% can be set if required. However, some lamps can become unstable at low dimming levels, in particular CFL’s.
If lamps become unstable at low dimming levels, they typically flicker or pulse on/off. The dimmer allows the minimum brightness to be set to a level above the point at which the lamp flickers/pulses.

Step 1
Enter into the dimmer Setup Mode – See PART A (page 9)

Step 2
Click the dimmer push button twice

Step 3
LED will blink 2 times
Note: To cancel/exit do nothing for 30 seconds
Note: If more than one dimmer is connected to the same load (see pages 5-7), all dimmers connected to this load will now blink 2 times

Step 4
Adjust dial to required MINIMUM brightness level
Note: If more than one dimmer is connected in parallel (see pages 5-7), wait for 3 seconds for the other connected dimmer to learn the new minimum level
Note: To cancel/exit do nothing for 30 seconds

Step 5
Click once to save & exit

Note: If more than one LED smart+ device is connected in parallel, the minimum brightness levels only needs to be set in one device. The setting is automatically saved to all other devices connected in parallel

Specifications

Maximum cable distance from any LED smart + device to the parallel junction point| 50m (for example, two dimmers can be separated by up to 100m provided that the maximum distance from the furthest dimmer to the parallel junction point is no more than 50m).

** Some LED lights do not turn off completely when used with two wire devices such as LED smart+. This is due to the small amount of current which flows through the device to the load when switched off. The result with some LED light sources can be a small amount of light output when the LED smart+ is in the off position. If this occurs, it is recommended that a Diginet ‘Load by- pass’ device (Item MMBP) is added to the lights / dimmer installation.

Compatible Load Types

| Dimmable LED Lamps| 400W| The LED driver must be dimmable. Maximum permitted number of drivers is 400W divided by the driver nameplate power rating. Due to variety of LED lamp designs, maximum number of LED lamps is also dependent on power-factor result when connected to dimmer.
| Electronic Transformers| 400W|
| Standard iron-core transformers| 250W| Due to variety of transformer designs, max LV lighting load is also dependent on transformer efficiency.
****| Toroidal iron-core transformers| 300W|
| Incandescent| 350W|
| Dimmable CFLs| 400W| Due to the variety of CFL designs, the maximum number is make/model dependent.

Incompatible Load Types
Ceiling Sweep Fans and Exhaust fans.

Multi-Gang De-Rating

Number of times per plate| De-rating factor| In applications where multiple dimmers are installed in a multi-gang plate, a de-rating factor is applied to the maximum load as follows.
---|---|---
1| No de-rating
2| 0.85
3| 0.7| | De-rating Example
4| 0.55| Two LEDsmart+ devices installed in a wall plate. The maximum LED load which can be connected to each device = 400W x 0.85 = 340W per device.
5| 0.4
6| 0.25

INTRODUCTION

LEDsmart+ dimmers, timers, switches and occupancy sensors include MultiMate™ technology. These devices have revolutionized multiple point control of lighting whilst using conventional wiring practices.
Even when not used for multi-way control, their superior compatibility with LED lighting loads makes them the best wall plate lighting controls in the market.

MULTIMATE™ TECHNOLOGY

MultiMate™ is the technology inside the range of high quality LEDsmart+ dimmers, timers, switches and occupancy sensors. It allows multi-way control of lighting loads without the need for an expensive control system. MultiMate™ technology is suitable for both new and retrofit installations.

MultiMate™ technology enables multiple LEDsmart+ two-wire devices to be wired in parallel when two-way, three-way or multi-way dimming and switching is required.

When connected in parallel, LEDsmart+ dimmers, timers, switches and occupancy sensors allow dimming and switching of connected lighting loads from multiple locations without any additional wiring. No strapper wires, dedicated remote switch wiring or control bus is required.

HOW MULTIMATE™ WORKS

MultiMate™ products use a patented method of communicating with each other using the mains wiring. By this means dimmers, timers, switches and occupancy sensors can communicate on/off, level, and settings to other LEDsmart+ products on the same circuit.

INSTALLATION

In normal cases, existing switches can be removed and replaced by MultiMate™ dimmers, timers, switches and occupancy sensors. Please refer to the installation instructions for common wiring methods used for 1-way, 2-way, 3-way and other configurations.

TROUBLESHOOTING

Like all products, sometimes there can be problems caused by the electrical behavior of the building wiring, or that of the lighting loads. This document describes some cases found from real-world product experience and their solutions.

Each of the following pages describes a problem and solution. In some case additional product(s) may be required.

APPLICABLE PRODUCTS

• Dimmers: MMDM/PB & MMDM/RT
• Timers: MMTM/PB & MMTH/PB
• Switches: MMSW/PB
• Occupancy Sensors: MMSE/PR

FLICKERING OR FLASHING WHEN OFF OR AT LOW DIMMING LEVELS

Modern LED lighting has revolutionised high brightness low power lighting.

Unfortunately, some LED loads can have problems with dimmer compatibility. This can be observed when lamps flicker or flash when set to low dimming levels or when a MultiMate™ device is set to the OFF condition.

The MMBP load bypass is wired across the lamp. It will resolve almost all issues associated with dimming of LED lighting, including:

• Lamp glow when turned off;
• Flickering or pulsing of the lamp when turned off or to low dimming levels; and
• Flickering or pulsing of the dimmer LED status indicators.

Solutions for lamp flickering at low dimming levels
Solution 1: Use the setup functions of the dimmer, timer, switch or occupancy sensor to adjust the MINIMUM dimming level to a higher value. Refer to the product installation guide for details.
Solution 2: Fit a load bypass device – order code MMBP.
Solution 3: In extreme cases, both the MMBP and a raised minimum level may be needed.

Solutions for flickering or pulsing of dimmer LED status indicators.
Solution 1: Fit a load bypass device (MMBP).
Solution 2: Newer model dimmers introduce CLM mode. Use the setup guide for your product and activate CLM mode.
Solution 3: In extreme cases, both the MMBP and enabling CLM mode may be needed.

Solutions for lamp flickering or flashing when turned OFF
Fit an MMBP load bypass. It is designed for this issue. Similar products are also available from other manufacturers.

How to install the MMBP load bypass device
The MMBP load bypass device is installed in parallel with the load, across the switched Active and Neutral, as shown in the diagram below.

Caution: Do not wire the MMBP across the dimmer terminals. This will not be effective.

CROSSTALK

Crosstalk happens when several MultiMate™ circuits are installed in the same building, and adjustments on one circuit cause interference on another circuit. The interference may be observed as:

• Lighting changes on one circuit cause lighting changes (on / off / change of level) on some other circuit; or
• Lighting changes on one circuit cause another circuit to turn off.

If a lighting load is flickering or flashing at low dimming levels or when turned off (and no dimmer / timer / switch is being adjusted) the most likely cause is a poorly designed lighting load. In that case, please refer to the section “Flickering or flashing when off or at low dimming levels”.

Causes
If the mains supply has a high source impedance, this can cause crosstalk: where the communication of one set of dimmers interferes with adjacent dimmers – especially if the different dimmer circuits share a common active feed to the same switch plate.

Reasons for High source impedance may include one or a combination of:

• Old substation or local step-down transformer running close to maximum capacity;
• Long cable run from step down transformer to building;
• High resistance terminations on active feeds and/or neutral returns; and
• Neutral returns from a common active feed having significantly different run lengths back to the switchboard – good practice would be to link together neutral returns from a common active feed as close as possible to the loads.

A best practice is for wiring from the distribution panel to the multi-way control location to use twin & earth cabling, keeping active & neutral together for as long as possible. This results in the lowest supply impedance. Long runs of single-cable active wiring and separate neutral wiring should be avoided.

Solution when the Multi-way function is not required
If the multi-way dimming function is not being used: follow the directions in the product Setup Guide to disable the MultiMate™ operation. This prevents the dimmer / timer / switch / sensor from sending and receiving the MultiMate™ commands.
Change this setting for all affected dimmers in the building when multi-way dimming is not needed.

Solution when the Multi-way function is required
When the multi-way dimming function is required, an inline MMDM/ID Inductive Decoupler may be required – these should be connected between the last dimmer in the control chain and the load.

FANS, FLUORESCENT LIGHTING AND NON-DIMMABLE LOADS

MultiMate™ dimmers, timers, switches and occupancy sensors are designed to control dimmable lighting loads.

Sometimes these products need to control non-dimmable loads, for example fluorescent lighting, non-dimmable LED lamps, or bathroom exhaust fans.

Direct wiring of these loads to MultiMate™ products may cause incorrect function of the load or the MultiMate™ product.

To Control fans and non-dimmable loads

The MMSR MultiMate™ Slave Relay presents a dimmable load to MultiMate™ devices. When the dimmer level exceeds a threshold, the relay is operated and switches on a non-dimmable load.

Combinations loads are possible on a dimmer: a dimmable LED load may be used on the same circuit as non-dimmable loads. In this case, when the dimmer level is higher than a threshold, the relay is operated to switch the non-dimmable load(s) on and the dimmable load will continue to respond normally. This is shown in the wiring diagram below. Properties of the MMSR Slave Relay
The Slave Relay has voltage-free contacts, and is rated at 10AX. SELV load control is possible when using the isolating barrier that is included.

The Slave Relay is suitable for use with trailing edge phase control dimmers. The Slave Relay can satisfy the load requirements of LEDsmart+ dimmers / timers / switches or occupancy sensors by itself. Using an additional dimmable lighting load is optional.
