CAN Bus Terminator
The A3 assembly ensures that the CAN bus also functions with undocked changeover tables. During
undocking, a CAN terminating resistor is switched, which maintains the CAN bus function and commu-
nication.
If the terminating resistance is measured with the machine switched off and the changeover tables con-
nected, you will be able to measure 30 Ohms at the Sub CAN bus (with 500kbit/s). Reason: There are
4x 120 Ohm resistors switched parallel. When the machine is switched on, the resistors switched in A3
will be deactivated.
