The transition of the output signals when changing a cartridge on LUB-V in switched-on
state is shown and described below:
Description:
LUB-V is properly connected to an external controller via the electrical interface and
connected to the power supply.
Pulse control mode PUL is activated on LUB-V, E1 is displayed in the LCD and the red
LED lights up.
l
The empty cartridge is detected after a dispense, the output signal of LUB-V is initially
a 0.5Hz square wave signal (empty state signal) (0/+24 V).
l
Z1 indicates the period of removing the empty cartridge. The output signal of LUB-V
now changes from a 0.5Hz square wave signal to a permanent low signal (0V).
l
Z2 indicates the period of screwing on a new, full cartridge. The output signal of LUB-V
now changes from a permanent low signal (0V) to a permanent high signal (+24V). In this
way LUB-V signals to the external controller (PLC) that it is ready for operation again.
l
If the empty state signal has occurred during the execution of the control signal 12
seconds the outstanding strokes are continued after the new cartridge has been screwed
on.
LUB-V does not process any control signals until all errors have been eliminated.
