– all four flaps over the push-buttons for raising and lowering the component changeover tables
must be closed.
– the minimum operating pressure must have been reached.
– the software enable must have been given, thus activating the safety circuit.
– the power supply must be sending 24 V to the Start buttons and the protective contactor com-
bination.
– If one of the Start buttons is now pressed, the protective contactor combination (PCC) will
switch and activate the following components:
– 200 V link voltage for the servo amplifier for the gantry axes
– 100 V link voltage for the star axes
– 230 V operating voltage for the lifting table motors
– the servo unit will receive a "Servo enable" signal for the servo amplifier
– 34 V operating voltage is switched to the component changeover tables
– 24 V operating voltage is switched to the used tape cutters.
The machine is now ready for service.

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 .
