2.6.4.1 Overview of safety cutoff
When the placement machine is ready for operation, the contacts of all position switches and the
EMERGENCY STOP buttons are unlocked. If a protective cover, for example, is raised, the cor-
responding 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 bumper for the Y axis must be present.
– 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 the safety-controlled
supply voltages on and the placement machine will be ready for operation.
Safety cutoff components 2
The following components are monitored by the safety cutoff:
– Position switch for the two protective covers on the placement machine
– Two EMERGENCY STOP buttons on the placement machine
– Position switch for the COT inserts on the placement machine
– Protective switch for detecting the Y axis bumper
