This manual will guide you through the first run of the Central unit, providing an overview of the programming, firmware update, searching of connected units and basic functionalities.
Setting up CU Wiring - Basic Installation
It is essential to wire the central unit and associated components in a basic setup. This setup typically includes Central Units, Power Supply, Bus Separator, and Field Units like actuators or controllers.
Follow these steps to ensure a proper wiring configuration:
Central Unit Wiring:
a. Connect the power supply to the central unit using the bus cable.
b. Connect the data bus cables to the designated ports on the central unit. Ensure proper labeling and follow the color-coding specified in the manual.
Power Supply Connection:
a. Connect the power supply to the electrical mains according to the manufacturer's guidelines.
b. Connect the output of the power supply 27V DC to the designated input on the central unit or Bus separator.
Bus Separator Connection:
a. Connect the bus separator to the power supply 27V DC and the BUS terminals to central unit bus terminals using bus cables. Ensure correct polarity and secure connections.
b. If there are two bus, connect them to the bus terminals of the central unit using separate data bus cables.
iNELS Data bus carries both power and data, for CU3-08M, bus 2 power the central unit.
Field Unit (Actuators/Controllers) Wiring:
Connect the field units (actuators/controllers) to the bus lines using bus cables.
Check Connections and power on:
Double-check all connections to ensure they are secure and properly seated.
Verify that the wiring corresponds to the specifications in the installation manual.
Power on the central unit and associated components. Check for any error indicators or messages on the central unit. Refer to the manual for troubleshooting if necessary.
Following these steps should provide a solid foundation for a basic installation of the CU system.
To perform configuration, firmware updates, and programming on the Central Unit (CU), it is necessary to establish an Ethernet connection between the Central Unit and the iDM3. Follow these steps for a direct connection to a PC or laptop during the first run of the program:
Physical Connection:
a. Locate the Ethernet port on the Central Unit.
b. Connect one end of an Ethernet cable to the Ethernet port on the Central Unit.
c. Connect the other end of the Ethernet cable to the Ethernet port on your PC or laptop.
Network Configuration:
a. By default, the Central Unit comes with the IP address 192.168.1.1.
b. On your PC/laptop, change the network configuration to match the same network range as the Central Unit.
For example:
- IP Address: 192.168.1.X (X can be any number from 2 to 254)
- Subnet Mask: 255.255.255.0
- Default Gateway: Leave it blank
Open the iDM program on your PC or laptop.
In the dropdown menu, select the new project from default template
Configure the settings to recognize the direct Ethernet connection to the Central Unit. for that enter the IP of the Central unit. Use the Central Unit's default IP address (192.168.1.1) as the target address to connect to iDM.
Go to the device manager and select the Central unit and enter the iNELS address of the central unit.
Connect now to the Central unit
Using the connect button in the iDM connect to the central unit. Once it is connected the red connection will signalize to green.
Configuration and Programming:
Once connected, you can perform initial configuration, set up the device manager, function manager, system manager within the iDM program.
Firmware Update:
If a firmware update is required, use the download unit firmware option from drop down menu in iDM program to check the current firmware version and initiate the update process.
Always connect the CU to the iDM (laptop or PC) directly with ethernet cable to ensure a smooth firmware update.
Saving to Central Unit:
a. After configuring and programming, use the "Save to Central Unit" option in the Main Menu to upload the project to the connected Central Unit.
b. This step ensures that the configured settings and programming are stored in the Central Unit.
By following these steps, you should be able to establish the Central Unit for initial configuration, firmware updates, and programming during the first run of the CU program.
