5.14 CAN bus
The CAN bus is used in connection with the load dending start/stop features of the C6200 FlexGen.
The CANbus terminals are located on the front plate in the right side. The terminals are module
standard used in Data communication equipment. Therefore, use standard twisted pair patch cable
for CANbus wiring. The maximum cable length is 40 meters. The cable type should be 0.25 - 0.34
mm
2
(AWG23/AWG22). Cable resistance should be less than 26 m
Ω
per meter.
The first and the last module on the CANbus need a termination resistor (150
Ω) between lines A
and B. It is not necessary to connect external resistors. The C6200 FlexGen contains internal end of
line resistors for the CAN bus that can be activated by toggeling DIP switch 6 to ON position.
Therefore, on the first and on the last unit on the CAN bus, DIP switch 6 has to ON. Every C6200
FlexGen module must be connected to the same CAN bus network. Third party CAN nodes may
not be connected to the FLEXGEN CAN bus.
