Electrical Installation

Important: Before servicing the equipment, isolate the controller from mains power.
Ensure the system is installed with a power disconnector conforming to regulations. Use cable lugs that are suitable for the terminals used. The maximum allowable length of the connections to the analogue/digital inputs and to the analogue outputs is 100 m; the temperature sensor’s maximum length is only 50 m. After making the connection, gently pull on the cables to ensure they are sufficiently tight.

Note

• Secure the cables connected to the controller with clamps placed at 3 cm from the connectors.
• Ensure the earth conductor is bonded to the conductor that is connected to the terminal from J1.

Important:

• To avoid damage to the device, terminate wires to all connectors prior to plugging the connectors to the controller.
• Using a supply voltage other than specified can seriously damage the system and void the warranty.
• The controller should only be installed, serviced and inspected by qualified personnel and in compliance with national and local regulations.
• All the extra low-voltage connections should have reinforced or double insulation from the power mains.
• Avoid touching the electronic components to avoid electrostatic discharges from the operator to the components, which may cause considerable damage.
• Do not press the screwdriver on the connectors with excessive force to avoid damaging the controller.
• Using the device in any way other than specified by the manufacturer can compromise its protection.
• Only connectors supplied with the kit shall be used.

Power Supply

• Only use the SMPS-1 240VAC/21.6- 29VDC 15W Switch Mode Power Supply that is supplied with the kit.

Important:

• Using a supply voltage other than specified can seriously damage the controller.
• Make sure that the earth conductor is connected to terminal GND. Proper grounding should be applied to all the devices connected to the GW100.
• The power supply to GW100 should be kept separate from the power supply to the other electrical devices.

Note: When the controller is powered, the seven-segment LED lights up to show 01.

Operating Conditions

• Storage: -40 To 90 °C, 90% RH non-condensing
• Operation: -40 To 90 °C, 90% RH non-condensing

Network Communications

Ethernet Network Connections and Connectors

• It is recommended to use Cat5e UTP or above Ethernet Cable (IEC11801 and EIA/TIA 568 Compliant).
• The maximum length of an Ethernet connection is 100 m between consecutive devices.

RS-485 Network

• To improve the controller’s immunity against electromagnetic interference, the serial connection cable should be a shielded twisted pair cable, 2-core twisted pair shielded or 4-core two twisted pair shielded, depending on the isolation of the serial connection. The following rule applies:
• The serial port (J3 Disp) is isolated (functionally) from the power supply. A third wire is required in the serial cable to act as a common reference for the controllers. The serial port (J4 FBus) is not optically isolated and the common reference is already present; no third wire is required.
• For the RS-485 network, use a shielded twisted pair cable. The maximum allowable total cumulative data cable length between all devices is 500 m.

Note: Enable the 120Ω, 1/2W terminating resistors on the ICUNO-MOD board first and last devices in the network. See ICUNO-MOD Installation and Commissioning Guide (9590-3013) for details.
Important: Any Earth connections made to any controllers shall be from a common main Earth point.

Procedure for Earthing the Shield

• The shield of the cable of the J4 FBus terminal on the BMS Gateway (GW100) should be earthed.
• Earth is only one end of the serial cable shield (shield connected to every second device).

Universal Inputs/Outputs
Universal inputs/outputs are distinguished by the letter U.

• U1 is designated as a digital input for network parameter reset.
• U6 has been designated as a 0-10VDC output, drivable by BMS.
• U2-U5 and U7-U10 can be configured to accept the following to be monitored by the BMS for site-specific purposes:

Analogue Inputs

• NTC (10K@25)
• NTC (50K@25K)
• PTC1000
• 0-10 Vdc signals *
• 4 to 20 mA signals **
• Ratiometric probes ***

These values must correspond with the configuration of all connected ICUNO-MOD cards.

BMS Network Connection

• Ports available for this are Ethernet or RS485. However, only one port can be used and set as the network connection at a time.

Ethernet

• Ethernet is the default setting. This is used for BACnet/IP and Modbus TCP/IP.

NOTE

• If Ethernet is selected, J3 can be used to plug a CP05 or a CP10 terminal display.
• Changing the Port selection requires the BMS gateway to be rebooted to take effect.

RS485

• RS485 is selected for BACnet MS/TP (terminal J3).
• BACnet MS/TP configuration settings

• BACnet MS/TP port settings

NOTE
If RS485 is selected, J3 can only be used for BACnet MS/TP and a display terminal cannot be connected.
Changing the Port selection requires the BMS gateway to be rebooted to take effect.

Network Configuration IP Settings

• This allows access and configuration of the Gateway’s IP settings.

• To save the network configuration, ‘Update Config’ must be set to Yes.

NOTE
The Net configuration menu is only visible when the BACnet port is set to Ethernet in menu Bc02

Troubleshooting

Restoring the Default values of the BMS Gateway
This provides the ability to physically reset the gateway’s network address to the default:

• IP: 192.168.0.1
• Subnet: 255.255.255.0
• Step 1. Turn off power from the mains supply by removing the fuse or switching the circuit breaker to the OFF position before performing the installation procedures.
• Follow sound LOCK-OUT/TAG-OUT (LOTO) procedures to ensure that the power supply is not re-energized accidentally.
• Step 2. Bridge U1-GND. Connect the ends of the jumper wire to the U1 and GND terminals to short.

• Step 3. Power system ON and wait to load.
• Step 4. Remove the jumper wire (connected to the U1 and GND).
• Step 5. Connect to the Gateway using the default IP address settings.
• Step 6. Configure desired IP address settings.
