2.8.4.1 Structure of SIPLACE EMERGENCY STOP Loops
The following contacts are connected in series and form the EMERGENCY STOP loop:
– Make contact elements for the four protective cover switches
– Normally open (NO) contacts in the two protective switches for the cover flaps over the PCB
conveyor
– Make contact elements for the two EMERGENCY STOP buttons
– Normally open (NO) contacts for the feeder module cover flaps (option)
– Make contacts for the four component trolleys or SWS modules (wafer feeders)
– Channels for the protective contactor combination SSK K6 and extension K6.1 (3TK2830-
1CB30)
In EMERGENCY STOP loop 2, the CAN bus signal of the signaling circuit (see section 2.8.4.2
) is
fed to channel 2 of protective contactor combination SSK K6. If the EMERGENCY STOP circuit is
closed, and the signaling circuit is not signaling a malfunction, then the two green LEDs for chan-
nels 1 and 2 light up, in addition to the green mains power check LED of the protective contactor
combination.

2.8.4.2 Signaling Circuit Structure
The signaling contacts for the protective switches of covers, cover flaps above the PCB conveyor,
of component trolleys or SWS module and of EMERGENCY STOP buttons are all queried individ-
ually. All the signaling contacts are closed when the machine is on standby. If a protective cover,
for example, is raised, the associated signaling contact opens. This change of state is signaled to
the control computer via the CAN bus. The relevant error message will be displayed on the user
interface of the station computer and the SWS.
2.8.4.3 Function of SIPLACE EMERGENCY STOP Loops
The following conditions must be fulfilled in order to start and operate the machine:
– The existing component trolley must be docked and connected.
– The SWS modules must be installed and connected (
EMERGENCY STOP interface connector
X1x)
.
– The SWS EMERGENCY STOP circuits (one per SWS) must be closed.
– All protective covers must be closed.
– Both cover flaps over the PCB conveyor must be closed.
– The EMERGENCY STOP buttons on the placement machine (2) and on the SWS (1) must
be released.
– The cover flaps (option) over the feeder modules must be closed.
– The minimum operating pressure must have been reached.
– The "software enable" signal must be active. This ensures that the safety circuit is closed.
– The power supply must be sending 24 V to the Start buttons and the protective contactor
combination.
The machine is ready for operation as soon as one of the start buttons is pressed.
