4.2.8 Safety and Control Loop(HF/HF3 bis MA.Nr. xx)
Please Note: For machine type A you consult the enclosed circuit diagrams.
4.2.8.1 Émergency Stop Loop (safety loop)
Following contacts are switched in serial and build the safety loop: _ 4
– 4 protective cover switches (main cover).
– conveyor cover switch.
– contact on component change over table
– emergency stop button must be released
Fig. 4.2 - 13 safety loop
If the emergency stop loop is closed, 24 V will be present on K5, contact 3. Another 24 V signal
travels to each CAN I/O module as
’emergency stop loop OK’ and signalize that all covers are
closed and table connected.

4.2.8.2 Control loop
Component Table Loop 4
The 4 component tables are switched in parallel mode. If 1 or more table is not connetcted, the
contact is closed and the 24V signal is set on the CAN I/O module in section 2 and shows which
component table is not connected.
Fig. 4.2 - 14 component table loop
Cover control Loop 4
The cover control loop consists of 6 contacts (4 cover and 2 transport) and they are switched in
parallel mode. If 1 ore more cover is open, the contact is closed and the 24 V signal sets an input
on CAN I/O module in section 4 and shows, that any cover is open.

Stop Button Loop 4
The stop button loop consists of 6 contacts which are switched in parallel mode.
If 1 ore more stop button is pressed, the contact is closed and the 24 V signal sets an input on
CAN I/O module in section 4 and shows, that any stop button is pressed.
