Description safety loop: 4
If the emergency stop loop is closed, 24 V will be present on K5, contact 3. Another 24 V signal
is activated at 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.
