CRS receiving unit
Description
2 CRS receiving unit
2.1 Description
The receiving unit uses the CANopen® communication protocol to communicate in a CAN bus network. The receiving unit acts as a slave node within this network.
STOP and SAFETY commands are sent via CAN network and also activate their corresponding outputs.
It is not possible to only rely on the CAN communication status to maintain or bring the remote controlled
machine to a safe condition. Messages sent by the radio remote control via CAN network do not in fact ensure the same safety features as the corresponding commands that are directly carried out by the receiving
unit's safety outputs. Please refer to chapters 7 and 6 for instructions to correctly wire such outputs.
