To be able to start the machine the
safety loop must be closed . The safety
loop consists of:
E-Stops
Component flaps
protective covers
component tables
pressure sensor
With the safety loop closed two functions are fullfilled :
Via the SLIO-module 1
and the
CAN-Bus all devices
are recognized and no error message is sent from the
machine controller to the station computer.
24V are also connected to the SSK giving the
permission to activate the machine software .

The placement system cannot be used in placement mode until all the supply voltages have been
enabled by the protective circuit. The following conditions must also be fulfilled:
– All four component change-over tables must be docked.
– All covers must be closed.
– Both emergency stop push-buttons must be released.
– All four component flaps over the component tables must be closed.
– The software enable signal must have been sent.
The enable signal is then sent to contactor SZ4 in the power supply unit via port 2 (X2dm) of CAN
input/output module 1 in sector 4 of the distribution board (see block diagram "Distribution board,
sector 4, 00336153-XXXXXXTD3 in the detailed circuit diagrams).
Contactor SZ4 switches 24 VDC to
– L+ on the combined contactor/protective device SSK
– the Start button at X4 of the SSK and
– the emergency stop loop at X3 and X5 on the SSK.
If 24 V is present at L+ on the SSK, the green "Power" LED on the SSK will light up. The message
"M ready" is returned to the computer via port 1 (X1dm) of the CAN input/output module 1 in sector
4 of the distribution board. If the safety loop is closed (covers closed, emergency stop button not
pressed), 24 V is sent to terminals X3 and X5 on the SSK.
If one of the Start buttons is pressed, the SSK switches and the green LEDs for channel 1 and
channel 2 light up. The five normally open contacts on the SSK switch five independent circuits
(see HS-50 power supply, 00336145-010101LD4, in the detailed circuit diagrams):
