2.6.5 EMERGENCY STOP loops and signaling circuit
2.6.5.1 EMERGENCY STOP loop structure
The following contacts are connected in series and form the EMERGENCY STOP loop:
– Make contact elements for the four protective cover switches
– Make contact elements for service flaps (up to 4 service flaps available as an option)
– Normally open (NO) contacts for the two EMERGENCY STOP buttons
– Make contact elements for the four component trolleys
– Channels for the protective contactor combination SSK K6
In addition to analyzing the EMERGENCY STOP loop with the SSK K6, the software also checks
the signaling contacts of the monitored switches. If all contacts are closed (make contact), the soft-
ware sends a digital CAN bus output signal from the I/O control unit to the SSK K6.

2.6.5.2 Signaling circuit structure
The following modules in the signaling circuit are queried individually:
– The protective cover switches
– Protective switches for service flaps (up to 4 service flaps available as an option)
– Signaling contacts on the component trolley
– EMERGENCY STOP button
All the signaling contacts are closed when the machine is on standby. If a protective cover, for ex-
ample, is raised, the associated signaling contact opens. 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.
2.6.5.3 Description of the functions of the EMERGENCY STOP loops
The following conditions must be fulfilled in order to start and operate the machine:
– All component trolleys must be docked in and connected.
– All protective covers must be closed.
– All service flaps must be closed (up to 4 service flaps available as an option).
– Both emergency stop buttons must be released.
– The minimum operating pressure must have been reached.
– The software release ("Control ON") must be enabled, so that the start signal from the "Start"
button can switch on the SSK protective contactor combination.
– 24V- are made available by the output of the AC/DC converter to the start button and the pro-
tective contactor combination (SSK).
If one of the start buttons is now pressed, the protective contactor combination SSK K6 will switch
and the machine will be ready for operation.
