Pin assignment
Pulse module
Pin assignment
CH1P Volume pulses (independent of flow direction),
active „low“
CH1D Direction flag, „high“ = forward flow
CH2P adjusted volume pulse =
forward flow minus backflow,
active „low“.
During a backward flow no pulses are send
to the output. After renewed forward first the
pulse numbers which are stored in the
memory will be deleted. This pulse numbers
are generated from the previous backward
flow. After deleting the memory forward
pulses will be send to the output only.
CH2C Backflow compensations flag.
This flag is „low“, if currently a backflow
compensation is running
TAMP Alarm flag,
signalizes the removal of the pulse module
from the register or low charge of battery,
active „high“
GND Ground
