IntroductionWelcomeThis unit provides a very versatile interface between an iCANnet™ system and other control systems. Fitting in the smallest of the iCAN™ system controller boxes this compact unit can be mounted virtually anywhere. It has eight inputs, which may be configured to be either digital or analogue. The unit also has eight volt-free mains rated low power relays. These allow a wide range of external equipment to be controlled. All inputs and outputs have configurable functionality. In addition to the control inputs/outputs there are eight digital outputs which can be used for LED indication of switch activity or digital control channels in their own right. As well as the essential connections to the iCANnet network, there are also terminals provided for connection to RS485 systems.

This interface allows the iCANnet™ network to control other systems and other systems to communicate with the iCANnet™ network. The unit is fully configurable and may be programmed to perform many functions, including curtain or blind control, the control of screens, audio-visual and other presentation equipment or con-trolling contactors for heavier power applications. With the control inputs set to analogue, any 0-10V source can be programmed to control system functions. The unit may also be configured such that system sequenc-es could be activated by a motion detector or any other device on the iCANnet™ network.

The Relay Interface is built and tested to strict safety regulations. By following the steps listed below and else-where within this guide, you can ensure safe installation and operation of these controller units.

• The Relay Interface must be installed only by a qualified electrician.

• The installation must comply with the appropriate electrical codes and regulations in force in your area.

• The Relay Interface is designed for indoor installation and use only. The unit can, however, be used to control appropriately certified exterior fixtures.

• Ensure that all wiring used conforms fully to local specifications and is sufficiently rated for the installation.

• All new wiring must be fully verified before applying power.

• The high voltage supply should be fed to the Relay Interface via an external isolation breaker with sufficient capacity for the planned installation.

• Ensure that the supply is fully isolated at an external breaker before removing the chassis covers. Test that power has been removed before starting to handle conductors.

• Ensure that high voltage and low voltage wiring remains separate.

Ambient atmosphere requirementsTemperature: 0°C to +40°C (32°F to 104°F)Humidity: 0 to 95% non-condensing

Mounting HolesThe unit is provided with four 6mm (1/4”) diameter fixing holes for wall mounting.The mounting holes can be accessed by undoing the four screws on the front cover and removing it.

Connecting the SupplyThis unit requires a nominal 230V single phase supply (Live, Neutral and Earth) with 1A capability.Keep the supply wiring segregated from the relay con-nector cabling.Ensure all supply connections are fully tightened.A knockout, suitable for a 19mm (3/4”) cable gland, is provided for the supply entry point.

iCAN Connectors

iCAN devices are ‘daisy-chained’ on the network. Spurs from the Network are not permitted and will result in communications problems. Devices on an iCAN network can be wired in any order. Termination is required at both ends of the network.

RI-2

The RI-2 has in-built network termination. If the RI-2 is at the end of the network, ensure the CAN TERM jumper is fitted in the Termination On position.

additional 12V power supply is used.

RS485 ControlAn RS485 port is provided for connection to third party devices or PC integration.

The communications settings are configurable from iCANsoft.The default settings are:Baud Rate: 9600 BaudData Structure: No parity, 8 data bits, 1 start bit, 1 stop bit.

A removable 4 way connector block is provided for the connection of RS485.

RS485 TerminationRS485 networks are daisy-chained. Devices at either end of the network must be terminated. If the RI-2 is at the end of the network, ensure the appropriate jumper is fitted in the termination ON position, as in the diagram:

Alarm InputsThe default action for the alarm inputs is for all outputs to switch on. These are designed for integration with emergency control devices and building management systems, using volt-free switch inputs. The default action for the alarm inputs is for every chan-nel of the source controller to turn on. They will then remain in this state, regardless of any other command received, until the inputs are opened again.

Connections for RS485 and Alarm Inputs

OperationThe relay interface can be energised without network cables being connected.

A flashing green LED indicates that the unit is powered and operating normally.

When first energised after installation, the unit will switch all relay outputs on. This allows verification of the output load connections.

Intermittent flashing of the red LED indicates iCANnet messages are being transmitted & received.

An iCANnet fault (including non-connection to the net-work) will be indicated by a permanently lit red LED.

If iCANnet cables are connected after the unit has been energised, it should be noted that cables will be carrying low voltage signals and misconnection of these cables could result in damage to devices on the network.

Commissioning

The relay interface has two service switches with green & red LEDs located at the base of the unit.

The service switches are used for:• Sending a message to identify the device on the network• Entering Diagnostic Mode

In diagnostic mode, the outputs can be tested by switching them all on and off (override mode) or by switching them sequentially (sequential test mode).

It is possible to enter Diagnostic Mode even if the unit indicates an iCAN fault.
