Description:
The FP4 D is properly connected to an external controller via the electrical interface
and connected to the power supply.
The empty state of the cartridge occurred after a donation, the output signal of the
FP4 D is initially the 0.5Hz square wave signal (empty state signal) (0/+24 V).
Z1 indicates the time of removal of the empty cartridge. The output signal of the FP4
D now changes from a 0.5Hz square wave signal to a permanent low signal (0V).
Z2 indicates the time for screwing on a new, full cartridge. The output signal of the
FP4 D now changes from a permanent low signal (0V) to a permanent high signal
(+24V). In this way the FP4 D signals to the external controller (PLC) that it is ready for
operation again.
If the empty state signal has occurred during the execution of the control signal 12 se-
conds, the outstanding strokes are continued after the new cartridge has been screwed
on.
The FP4 D does not process control signals until all errors have been eliminated.
