Topic 2: Installing load controllers
Overview
• This document is a guide to installing Philips Dynalite components to a state where it is really to be commissioned.
• Every Dynalite product is delivered with a comprehensive instruction manual. It is important that you read the installation instructions for each product before using this guide.
Learning outcomes
By the end of this topic you’ll be able to detail the installation steps for the following devices:
• Wall mounted devices
• DIN rail mounted devices
• Mounting structured wiring boxes
• Mounting panels
• Mounting sensors
• Mounting touch screens
• End of line resistors.
Hardware controls
Service LED and switch
The Service LED has 3 signaling modes, which are useful for troubleshooting:
• Blinking slowly (1Hz) = Normal Operation
• Blinking fast (0.25Hz) = Network Activity Detected
• On = Fault.
The Service Switch, when pressed, causes a “sign-on” message to be transmitted onto the network. If the transmission is successful, the Service LED will indicate “network activity detected”. The Sign-on message contains information about the device, such as: box number, device type and embedded software version. This information is captured by DLight
configuration software to speed up commissioning of large systems.
The Service Switch three states are:
• 1 push = Transmit Network ID
• 3 pushes = All Channels 100%
• Push & hold for 4 sec = Reboot.
AUX input
This is a dry contact interface that is active low. The dry contact is connected between the AUX and GND terminals on the DyNet connector strip. The function of the AUX input is
programmable. Ensure that the cable length between the dry contact and terminal strip is no longer than 2 meters.
Top set
This adjusts the maximum output that all other control sources can select, i.e. if the Top Set is fully clockwise, 100% selected by a control source will give 100% output. If it is fully anti-clockwise, 100% selected by a control source will give 50% output. This control is useful for extending lamp life and can be operated without any form of network control, effectively turning the device into a stand-alone power conditioner and lamp protector.
Wall mounted devices
Select a suitable location
Some of Philips Dynalite products are available in the wall mounted form factor, these include:
• Load controllers
• Network Bridges.
Wall mounted devices are designed for indoor use only. If installing in an external location, the device must be housed in a suitable well-ventilated enclosure. Choose a dry location that will be accessible after the installation is complete.
To ensure the cooling system functions correctly, the load controller should only be mounted vertically, the right way up.
The load controller will generate heat when operating, approximately 2 Watts per Amp of load, and requires an air gap of 200mm on each side and at the top and bottom of the device.
This air gap is also required to ensure serviceability of the load controller without complete removal from the mounting surface.
This device may emit some mechanical noise. Take this into account when deciding the mounting location.

Fixing the device
The load controller has integral mounting brackets attached to the enclosure. The brackets are designed to accommodate 4 fixing screws up to 8mm diameter.
The load controller can be fixed to the wall without opening the cabinet or removing covers.
Make sure no dust or other debris enters the device during installation.
Do not leave the front cover off for any length of time. Excessive dust and dirt can degrade the cooling of internal components.
Allow for cable entry
Supply and load cables enter the enclosure at the top. If these cables are fed from below the mounting position, they should be routed around the enclosure to enter at the top. An alternative method is to stand the enclosure off from the mounting surface by mounting it on a cable tray or a Unistrut style product.
The cables can then be routed between the enclosure and the mounting surface, and enter the enclosure via the cut out provided on the mounting face. The control cables enter at the bottom of the enclosure. Control cables should never be run in the mains voltage sections of the
enclosure.
Supply & load cable
Supply Cables -The supply input terminals are located toward the top of the enclosure and consist of Earth, Neutral, and Phase. The supply cables should have enough capacity to allow the device to be loaded to its maximum capacity.
Load Cables - Load cables can be terminated on the 4 x 3 way load terminal strips (one for each channel), a Neutral link and an Earth link located at the centre of the enclosure. It is important that an individual output circuit is not overloaded. Calculate the intended load, and ensure that it is below the maximum capacity of an individual channel. To ensure compliance with interference standards, the load neutral cables must be individually connected to the neutral link terminals inside the cabinet. Never use a common neutral at a remote location.
Emergency Lighting Connections - Connect the emergency lighting circuit active to the load side on the circuit breaker for the relevant channel, as indicated by the labels next to the circuit breakers. Do not remove any cables that may already be terminated at this location.
Energizing the Device - If it is necessary to energies load circuits before any control cables are connected, it is acceptable to replace the cover and energies the device immediately, as the default factory programming is to have all channels set to 100% output. This device should be de-energized before terminating the control and data cables.
Powering up the dimmers prior to commissioning
All devices are pre-programmed with a default configuration before leaving the factory. When all the devices are installed and networked together, every button panel will control all the dimmers.
The Dynalite engineer requires the system to be installed to this level to commission the project successfully.
All Dynalite load controllers are set to provide full output to the load as the default, irrespective of having the network connected. When the network is connected, every button panel will operate every circuit of every device.
Operating environments
This device is designed for indoor use only. If installing in an external location, the
DLE1205 must be housed in a suitable well ventilated enclosure. Choose a dry location that will be accessible after the installation is complete.
In addition the load controller must not be in a location that exceed the following limits for temperature and humidity:
0º to 40ºC ambient temperature 0% to 95% RH non condensing.
DIN rail mounted devices
Instructions
A number of devices are available in the DIN rail form factor, these include:
• Load controllers
• Time clocks
• Power supplies
• Network gateways
• Dry contact interface devices.
Follow the points below to ensure correct installation of DIN rail mounted devices:
• Mount the device on a DIN rail inside an approved enclosure.
• Calculate loads to ensure any channels are not overloaded, then connect loads to the output channels.
• This device must be earthed
• Connect data cables to the device as per diagrams in the previous topic.
• If the Auxiliary input is to be used, connect a dry contact device in between the AUX and GND terminals. Keep cable runs between the device and the dry contacts under two meters. The function of the Auxiliary input will need to be programmed at the time of commissioning.
• Every Dynalite product is delivered with a comprehensive instruction manual. It is important that you read the installation instructions for each product before installation.

Multi controllers
When installing Multi Controllers there are some additional considerations to take into account regarding the controller modules.
Verify that the Output Cards supplied are suitable for your intended loads. Pay attention to any Output Card specific documentation that may be packed with Output Cards. When dimming electronic transformers, ensure that the intended transformer is included in Dynalite’s Compatible Electronic Transformer List, the latest revision is available at dynalite-online.com
1. Snap the cover off the base unit. Plug each Output Card into the slots provided on the main circuit board. Replace the base unit’s cover. If using different types of Output Cards, remember which type is associated with each set of output terminals.
2. Mount the device on a DIN rail inside an approved enclosure.
3. Calculate loads to ensure any channels are not overloaded, then connect loads to the output terminals. The maximum loading of this device is 16A. A de-rating factor may need to be applied if installed in a smaller sealed switchboard when using Leading or Trailing edge dimmers, contact your dealer for details.
The output card ratings are:
• DDBM100 Ballast Controller – Digital mode : 5 x Ballasts
• DDBM100 Ballast Controller – DSI mode : 15 x DSI Ballasts
• DDBM100 Ballast Controller – 1-10V mode : 10mA source, 20mA sink
• DDCM102 Curtain Controller : 2 Amps
• DDFM102 Fan Controller : 1 x Fan, max 400VA
• DDLM102 Leading Edge Dimmer : 2 Amps
• DDLM104 : Leading Edge Dimmer : 4 Amps
• DDRM104 Relay Controller : 4 Amps
• DDTM102 Trailing Edge Dimmer : 2 Amps
WARNING : Ballast controller output is referenced to mains neutral and is live. Only mains rated cables and control ports should be connected.
Ensure that lamp holders are marked with the maximum permissible lamp size that will not overload a channel. This is to protect the end user from inadvertently overloading a channel by replacing lamps with higher wattage types.
1. Every time the front cover is removed, ensure that all modules are correctly seated and locked into sockets before the cover is replaced.
2. Ensure that lamp holders are marked with the maximum permissible lamp size that will not overload a channel. This is to protect the end user from inadvertently overloading a channel by replacing lamps with higher wattage types.
3. Connect a single phase 16A feed to the supply terminals, via a 16A circuit breaker or HRC fuse. This device must be earthed.
4. Connect data cables to the device as per diagrams below.
5. The Auxiliary input is connected via a dry contact device in between the AUX and GND terminals. Keep cable runs between the device and the dry contacts under two metres.
The function of the Auxiliary input will need to be programmed at the time of commissioning.
Structured wiring boxes
Select a suitable location
This device is designed for indoor use only. If installing in an external location, the DBC905 must be housed in a suitable enclosure. Choose a dry location that will be accessible after the
installation is complete. To prevent dust or particle penetration the controller should be mounted so that connector apertures do not face directly upwards. Recommended mounting methods include surface wall, slab, cable tray or “drop rod” suspension.
Fixing the device
The controller has two keyhole slots located at each end of the housing, which can accommodate fixing screws up to 6mm diameter. The preferred method of mounting is shown below using
“drop rods” with appropriate fastening clips.

Wiring terminations
Removable connectors are utilized for all wiring terminations to simplify maintenance, installation and replacement. Note that controllers are supplied without connectors. Please order
connectors separately as required.
Figure 48
Supply and output connections
The DBC905 is available in two configurations supporting popular structured wiring brands; CMS Electracom / Modular Wiring tag series and Wieland GST18 series. Units are designated by item code as DBC905C (CMS) OR DBC905W (Wieland).
Both cable vendors offer a range of wiring solutions and accessories for both the upstream supply and downstream load wiring. The upstream wiring solutions combine both the mains supply and floor network circuits into one wiring assembly, which can dramatically reduce installation time.
Please refer to respective vendor for guidelines on connector and cable assembly selection.

Network connections
Serial ports are used to interconnect other dimmers, smart control panels, sensors and AV controllers.
The DBC905 circuit design incorporates multiple layers of isolation to deliver robust fault tolerance and uncompromising safety. It should be noted that most structured wiring solutions for upstream supply circuitry which include both network and power (i.e. 5 pole systems) only provide functional isolation between the data and mains circuits. Where such wiring systems are used, the floor network must be considered at mains potential not SELV and all floor network wiring should include the appropriate provision for prevention of access to live parts.
The main floor network port on the DBC905 is isolated for this reason. The isolation will tolerate a fault which raises the floor network to mains potential.
Note that this does not include mains potential applied across D+ and D- which would of course result in destruction of circuit components. Isolation is also separately provided to the local DyNet ports and switch inputs. This ensures that all switch inputs and local network circuits are SELV and prevents propagation of faults from these circuits across the floor network.
Where an upstream structured wiring solution is used, care should be made when terminating network spur wiring at floor bridges (area controllers), to again prevent access to parts and wiring considered potentially live. In this case only DBC905 controllers should be connected to the floor network as they incorporate the isolated port. Under no circumstances should a
standard user interface be connected directly to the floor network as this may permit user access to potentially live parts.
All user interfaces such as sensors and panels should be connected to the local network ports on the DBC905 which provide SELV isolation from mains and the floor network. Where it is necessary to connect user interfaces to a floor network of this type, a bridge should be always used to provide effective isolation.
