With the machine switched on by the
main switch (Z1), power ist first supplied
over the inrush current limiter (EST) to
the primary side of the transformer
This causes a small feedback signal on
the secondary side, which activates
contactor SZ1.
With contactor SZ1 activated the inrush
current limiter (EST) is short circuit and
furthermore without function. The
machine is now ready for operation.
On the primary side can be found the power
supply for the service plug (Bu1),
the board net where the station computer and
the two monitor are connected to
and the power supply of the four lifting tavle
motor.

Supply voltage for the control unit
Supply voltage for the component table logic
Supply voltage for the component table to
drive the feeder modules
The SSK activates then contactor SZ2 and SZ3
by a 24V signal and voltage is supplied over
the inrush current limiter (ILS) to X and Y.
With a short delay also contactor SZ23 is
activated by the 24V to short circuit contactor
SZ3 as well as the inrush current limiter (ILS).
X and Y are now driven by full power.
