Safety loop
Description of emergency STOP circuit:
When the emergency STOP circuit is closed, there is 24 V present at K5, contact 3. A further 24 V signal
is sent as EMERGENCY STOP loop OK Sent to each CAN I/O module, indicating that the covers are all
closed and that the changeover tables are connected.

Control Loops
5.2.8.2 Control Loops
Changeover Table Loop
Changeover Table Loop
Changeover table loop
The 4 component tables are switched in parallel mode. If one or more tables are not connected, the
contact will close and 24 V will be present at the input of the CAN I/O module in sector 2 or 4.
Cover Control Loop
Cover Control Loop
Cover Control Loop
The cover control loop consists of 6 contacts (2 main covers, each with 2 contacts and 2 covers on the
conveyors (input and output)), which are switched in parallel mode. If 1 or more covers are open, the
contact will close and the 24 V will be present at the input of the CAN I/O module in sector 4. The same
applies to sector 2. This shows that one of the covers is open.
