Description:
The FlexxPump 125 is properly connected to an external controller via the electrical
interface and connected to the power supply.
The Pulse-Control-Mode PUL is activated on the FlexxPump 125, E1 is displayed in
the LCD and the red LED lights up.
The empty state of the cartridge occurred after a donation, the output signal of the
FlexxPump 125 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
FlexxPump 125 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
FlexxPump 125 now changes from a permanent low signal (0V) to a permanent high
signal (+24V). In this way the FlexxPump 125 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 FlexxPump 125 does not process control signals until all errors have been
eliminated.
Z1: Removing the empty cartridge
Z2: Mounting the new cartridge
