2.7.4 EMERGENCY STOP loops and signaling circuit
2.7.4.1 EMERGENCY STOP loop structure
The following contacts are connected in series and form the EMERGENCY STOP loop:
– Make contact elements for the two protective cover switches
– Make contact elements for the two bumper monitors of the Y axis
– Normally open (NO) contacts for the two EMERGENCY STOP buttons
– Make contact elements for the two component trolleys
– Channels for the protective contactor combination SSK K3
In the EMERGENCY STOP loop, the CAN bus signal from the signaling circuit (see section
2.7.4.2
, page 75) is fed to the protective contactor combination SSK K3. If the EMERGENCY
STOP loop is closed, and the signaling circuit is not signaling a malfunction, then the two green
LEDs for channels 1 and 2 light up, in addition to the green mains power check LED of the pro-
tective contactor combination.

2.7.4.2 Signaling circuit structure
The following modules in the signaling circuit are queried individually:
– The protective cover switches
– Bumper monitoring of Y axis
– 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 change of state is signaled to the
control computer via the CAN bus. An error message to this effect appears on the user interface.
2.7.4.3 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 stopper bumpers for the Y axis must be fitted.
– 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 K3 will switch
and the machine will be ready for operation.
