By attaching a Bus Terminal the blade contacts on
the left hand side of the Bus Terminal are
connected to the spring contacts.
The tongue and groove guides on the top and
bottom of the Bus Terminal Controller and of the
Bus Terminals guarantees that the power contacts
mate securely.

DeviceNet 5 pin open style connector.
The BX5200 Bus Couplers module has a recessed
front surface on the left hand side with a 5 pin
connector.
The supplied DeviceNet connecting socket can be
inserted here.
The figure shows the socket in the BX5200 Bus
Coupler.

Pin 5 is the connection strip's top most pin and is
not used.
Pin 4 is related to the CAN high signal.
Pin 3 is related to the screen and is internally
connected to Ground, thus the mounting rail, via an
R/C network.
Pin 2 is related to the CAN low signal.
Pin 1 is related to CAN bus Ground.
If all the CAN ground pins are connected, this
provides a common reference potential for the
CAN transceivers in the network.
X21 - Programming (COM 1 - RS 232).
It is recommended that the CAN Ground be
connected to earth at one location, so that the
common CAN reference potential is close to the
supply potential.
Since the BX5200 Bus Couplers module provide
full electrical isolation of the bus connection, it
may in appropriate cases be possible to omit wiring
up the CAN ground.

NOTE: In order for the Power Source to be able to
interrupt the welding operation if there is
any heart bit in data transmission, the bus
node has a disconnection watchdog.
If no data transmission takes place within 1
s., all inputs and outputs are reset and the
Power Source is then in the "Default"
state.
Once data transmission has been restored,
welding is resumed by the "Robot ready"
signal.
All DeviceNet output signals, coming from
Power Source, are set to 0 if CANopen
communication is not active.
