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.

2.8.4.4 Structure and Control of SWS EMERGENCY STOP Loops
The following input and output signals control the EMERGENCY STOP circuit:
– Input 1 = 1 > EMERGENCY STOP button on the SWS is not pressed
– Input 16 = 1 > SWS EMERGENCY STOP circuit for switching device K3 is closed
– Input 1 = 0 / IN16 = 0 > EMERGENCY STOP activation of the SWS (internal)
– Input 1 = 1 / IN16 = 0 > EMERGENCY STOP activation of the SWS (external)
– Input 15= 1 > Contactors K1/K2 = on, 48 V DC control for the motor amplifiers = OK
– Output 1 = K4 (on/off 150 ms) > Resetting EMERGENCY STOP > Starting SWS
– Output 16 = 1 > K5 = On "Feeder Present" signal to the SIPLACE
2.8.4.5 Function of the SWS EMERGENCY STOP Loop
The following conditions must be fulfilled to ensure that the EMERGENCY STOP switching device
K3 is enabled after the SWS is switched on:
– The SWS EMERGENCY STOP circuit is closed, i.e. the EMERGENCY STOP button on the
SWS is not pressed.
– The SIPLACE- EMERGENCY STOP circuit is closed, i.e. the protective cover is closed and
the start button is pressed.
– The initial condition of the inputs IN1 and IN16 is 1.
After that, the reset / start circuit is closed (by means of output 1 = K4 (on/off 150 ms) > resetting
the SWS EMERGENCY STOP).
–The K1/K2 contactors are switched on (24 V DC loop).
– The link voltage of 48 V DC to the motor amplifiers DMC-19540(20) is supplied.
– The motor voltage is activated afterwards via the Enable signal from the motor controller.
– The ABORT signal (motor amplifier DMC-19540(20)) is disabled via the K2 break contact.
– A 24 V DC EMERGENCY STOP voltage is supplied.
– The compressed air main valve Y1/PRS for the die ejector lift is switched on.
– The operating status indicator (white) on the SWS is switched on.
The SWS is ready to operate.
Enabling the EMERGENCY STOP
An EMERGENCY STOP can be triggered by:
– Pressing the EMERGENCY STOP button on the SWS.
– Pressing the EMERGENCY STOP button on the placement machine.
– Opening one of the protective covers of the placement machine.
