4.11.6. EtherCAT/Ethernet Line Interface
Ethernet transceivers require either isolation transformers or capacitor coupling for proper
functioning. The Gold Bell unit does not include such isolation, therefore you must take this
into consideration when designing the integration board.
In Sections 4.11.4 and 4.11.5, a schematic connection with a standard RJ-45 connector that
includes transformer isolation is described.
Other recommended connection options are:
• Gold Bell to an RJ-45 connector without an integrated magnetic isolation (e.g., M12
connectors). An isolation transformer is required.
• Connecting two EtherCAT ports on the same board can be done using capacitive coupling
or transformer coupling.
For more detailed explanations, including layout recommendations and component selection
guidelines contact Elmo’s technical support.
4.12. Powering Up
After the Gold Bell is connected to its device, it is ready to be powered up.
Caution:
Before applying power, ensure that the DC supply is within the specified range
and that the proper plus-minus connections are in order.
4.13. Initializing the System
After the Gold Bell has been connected and mounted, the system must be set up and
initialized. This is accomplished using the Composer, Elmo’s Windows-based software
application. Install the application and then perform setup and initialization according to the
directions in the Composer Software Manual.
4.14. Heat Dissipation
The best way to dissipate heat from the Gold Bell is to mount it so that its heatsink faces up.
For best results leave approximately 10 mm of space between the Gold Bell's heatsink and any
other assembly.
4.14.1. Thermal Data
• Heat dissipation capability (θ): Approximately 10 °C/W.
• Thermal time constant: Approximately 240 seconds (thermal time constant means that the
Bell will reach two-thirds of its final temperature after 4 minutes.)
• Shut-off temperature: 86 °C – 88 °C (measured on the heatsink).
