INTRODUCTION

The Clipsal® Two Channel (SLC5102BCLEDL) and the Four Channel (SLC5104BCL) Bus Coupler units are key input devices that allow voltage free mechanical switches, such as reed, pressure, micro or other switches, to be connected to the C-Bus™ Network. They transmit messages to output devices to control load states and provide all C-Bus switching commands, including: on, off, toggle, timer and dimming functions, etc. The Bus Couplers are designed to fit into typical wall boxes along with voltage free mechanical switches.

The Two Channel (SLC5102BCLEDL) Bus Coupler units may be wired to external LED to indicate the state of operation. The Four Channel (SLC5104BCL) Bus Coupler has built-in LED indicators on the front of the unit to indicate the state of operation.

The Learn Mode feature is also incorporated in these units, allowing a quick and easy way to program mechanical switches, to achieve various control functions such as: on/off, dimmer or timer.

A spring return type switch, such as a momentary contact switch, is recommended for dimming operations.

SAFETY PRECAUTIONS

This section contains important safety precautions that must be followed before attempting to install or maintain electrical equipment. Carefully read and follow the safety precautions below.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E.

• This equipment must be installed and serviced by qualified electrical personnel.

• Turn off all electrical power supplying this equipment before working on or inside the equipment.

• Always use a properly rated voltage sensing device to confirm that power is off.

• Replace all devices, doors, and covers before turning on power to this equipment.

Failure to follow these instructions will result in death or serious injury.



Megger® Testing

Do not Megger® test C-Bus data cabling or terminals. Megger testing of data cabling or terminals can degrade the performance of the C-Bus network.

HAZARD OF C-BUS NETWORK PERFORMANCE DEGRADATION

Do not Megger® test C-Bus data cabling or terminals as it can degrade the performance of the C-Bus network. Failure to follow this instruction will result in damage to the C-Bus network.

Transient Voltage Surge Protection

Use this unit only within the limits of the design specifications. Each unit incorporates transient protection circuitry. Additional external power surge protection devices should be used to enhance system immunity to power surges. It is strongly recommended that appropriate transient voltage surge protection be installed at all service equipment.



INSTALLATION

Follow the procedures in this section to properly install Two Channel and Four Channel Bus Couplers. Before installing the Bus Couplers, verify that wall boxes will accommodate both the switches and the Bus Couplers.

Network Considerations

The Bus Couplers draw 18 mA from the C-Bus network. Verify that an adequate number of C-Bus Power Supply Units are installed on the C-Bus Network to support the connected devices.

Configuration Options

The installer can program the unit in two ways:

• Using a personal computer

• Using Learn Mode.

Whichever method is used, each Bus Coupler must be assigned a unique unit address. A group address must be assigned for each channel on all bus coupler units.

When the units are being installed as part of a large or complex network, it is most efficient to perform the basic configuration before the units are physically installed. However, the units can be configured before or after physical installation.

Configuring with a Personal Computer

The following components are typically required to configure a Bus Coupler (specific items and product numbers can vary according to the C-Bus unit and network).

• PC with the C-Bus Toolkit software installed

• Bus Coupler Unit (SLC5102BCLEDL or SLC5104BCL)

• C-Bus PC Interface (SLC5500PC) or C-Bus Ethernet gateway (SLC5500CN)



Configuring without a Personal Computer using Learn Mode

The Bus Coupler is a C-Bus Input unit that allows users to set the relationships between Output Units and the Input Unit without a computer.

Note: Each output unit which is to be associated with the Bus Coupler in this way must be a C-Bus unit as well.

Learn Mode provides a quick and simple way to program the C-Bus Input units to provide basic functions.

To program the Bus Coupler using Learn Mode to turn on loads, connect each channel of the Bus Coupler to a conventional switch. Then do the following for each channel:

1. Enter Learn Mode by holding down a local override button on a C-Bus output unit for 10 seconds. The Unit and C-Bus indicators will begin to flash alternately.

2. Select the local override buttons on the output unit associated with the loads you want to control. The selected indicators will illuminate.

3. Place the (non C-Bus) switch you want to associate with the selected load in the ON position. The light on the Bus Coupler associated with this switch will light.

4. Exit Learn Mode by pressing any local override button on an output unit for 2 seconds.

Identifying the C-Bus Units and Their Locations

The location of each C-Bus unit must be tracked. Two recommended methods are given below, one for when the units are configured before installation (see section “Labeling the C-Bus Units”), the other for when the units are configured after installation (see section “Recording Each Unit’s Location”).

Labeling the C-Bus Units

When C-Bus units are configured before physical installation, it is important to label them to indicate where they are to be placed. One method for doing this would be to write each unit’s address directly on it.

NOTE: Verify that each configured unit has been marked to indicate where it should be placed in an enclosure or a building or site.



Recording Each Unit's Location

In order to track C-Bus units that will be configured after physical installation, they must be identified and their location must be recorded at the time they are installed.

NOTE: If a unit has already been configured and assigned a location on a site map, it is not necessary to make another record of its location.

HAZARD OF UNEXPECTED OR IMPROPER SYSTEM BEHAVIOR

• Properly record the physical location of each unit using the lift-and-peel label provided on the box and a site plan or location log.

• Retain location records and provide them to the person(s) responsible for configuring and commissioning the network.

Failure to follow these instructions can result in unexpected or improper system behavior.

Before installing a unit, use the following guidelines to record its location. Recording each unit's location is required for configuration with the C-Bus™ Toolkit software.

Each unit is identified by a unique serial number found on the box label (see the figure “Box Label with Lift-and-Peel Section”). The serial number provides important information for recording a unit's location.

Figure 1: Box Label with Lift-and-Peel Section

KEY:

A. Serial number

B. Bar code

C. Lift-and-peel section



The box label also has a bar code that can be read by an infrared scanner and used for a record of a specific unit’s location. A “lift-and-peel” section of the box label duplicates the box label’s information (see “Box Label with Lift-and-Peel Section” diagram).

To record the location of a unit, remove the lift-and-peel section from the box label and attach it to a site plan or other document. The lift-and-peel section now provides a record of the physical location where that unit is installed. When installing multiple units of one kind in an area or enclosure, such as six four-channel DIN dimmers in an enclosure, verify that the document or site plan indicates the relative position of each specific unit.

Connecting Bus Couplers to the C-Bus Network

Installation requires connection to the unshielded twisted pair C-Bus Network cable. Use a Category 5 data cable. Use the insulated bootlace terminals provided. Tighten the C-Bus Network terminal screws securely. The recommended torque for tightening terminal screws is 12 lb-inch (1.4 Nm). Do not exceed this torque.

NOTE: The C-Bus network connection is polarity sensitive. The polarity is clearly marked on the front of the unit

One loop-in removable terminal block is provided for easy wiring installation and maintenance.

HAZARD OF C-BUS NETWORK PERFORMANCE DEGRADATION

Do not Megger® test C-Bus data cabling or terminals as it can degrade the performance of the C-Bus network. Failure to follow this instruction will result in damage to the C-Bus network.

Bus Couplers do not have Remote Override (On/Off) functions. However, correct connections must be maintained for these services across the C-Bus Network.



Connecting Bus Couplers to Remote Switches and LEDs

The Two Channel Bus Couplers (SLC5102BCLEDL) with remote LED feedback and the Four Channel (SLC5104BCL) Bus Couplers enable the use of a wide range of conventional dry contact switch mechanisms to indirectly switch C-Bus loads.

The Bus Couplers are designed to fit within the wall box behind switches. Verify that the wall box will accommodate both the switch and the Bus Coupler. A small length of wire is used to connect these switches to the input terminals of the Two or the Four Channel Bus Couplers or remote LEDs to the input terminals of the Two Channel Bus Couplers (the Four Channel Bus Couplers do not offer remote LED indication).

Any type of appropriately rated insulated copper wire (solid or stranded) no greater than 12 AWG (3.1mm²) or less than 24 AWG (0.2mm²) may be used to connect between remote LEDs (SLC5102BCLEDL only), voltage free or dry contact switches or channel inputs (both SLC5102BCLEDL and SLC5104BCL). The maximum cable length is 39 in. (1m) per channel; however the total length of cable connecting the Bus Couplers to the remote switches in a single network should be kept to a maximum of 32.8 ft. (10m) to maintain communications across the C-Bus network.

Example:

• 10 channels at 39 in. (1m) or 20 channels at 19.68 in. (500mm).

If longer connections are required for the Two Channel or Four Channel Bus Couplers it is recommended that you use a Square D® Clipsal DIN® Mounted Auxiliary Input (SLCLE5404AUX), which has input isolation. The Auxiliary Input Unit is specifically designed for that type of application. However, the Auxiliary Inputs do not offer remote LED indication.


Isolate switch input and LED connection wires from all other electrical power source wiring, electrical noise sources, and grounded metal structures. Do not enclose bus couplers in multi-gang style wall boxes with switches wired to external power sources. Failure to follow this instruction will result in death, serious injury, and damage to the C-Bus network.



When connecting remote LEDs, use only those with a minimum current rating of 10mA.
