2.5.3.1 Overview of safety cutoff
When the placement machine is ready for operation, the contacts of all position switches and the
EMERGENCY STOP buttons are closed. If a protective cover, for example, is raised, the corre-
sponding switch and safety cutoff will be triggered. For the operator's information, this status
change is signaled to the control computer via a digital CAN bus input signal from the I/O control
unit. An error message to this effect appears on the user interface.
Prerequisites 2
The following conditions must be fulfilled in order to start and operate the placement machine:
– All component trolleys must be docked into place.
– All protective covers on the placement machine must be closed.
– The two emergency STOP buttons must be released.
– The minimum operating pressure must have been reached.
– The software release ("Control ON") must be enabled.
If one of the start buttons is now pressed, the safety cutoff (CBS) will switch and the machine will
be ready for operation.
Safety cutoff components 2
The following components are monitored by the safety cutoff:
– Position switch for the four protective covers on the placement machine
– Two EMERGENCY STOP buttons on the placement machine
– Position switch for the COT inserts on the placement machine
