Description of operation mode of the Digital In.
The contacts are numbered from bottom to top.
The PLC inputs are working only if the correct location of control has been set.
The actual pin setting can be seen under Info / View internal data / page8.
Zero:

Change from low to high: activate zero

Change from high to low: deactivate zero
Start: 
Change from low to high: activate START
Stop:

Change from low to high: activate STOP

When this inlet is longer high than chosen then ventilate it additionally.
Purge/gas ballast: 
Change from low to high: activate purge/gas ballast 
Change from high to low: deactivate purge/gas ballast
Clear:

Change from low to high: confirm error message
CAL:

Change from low to high:

When machine is in standby mode: start internal calibration. In case machine is
measurement mode: start external calibration. (Premise: external calibration test
leak has to be open and leak rate signal is stable)

Change from high to low:

External calibration: approve that external test leak is closed and leak rate signal is
stable.

High means: U > 13V(approximately 7mA)

Low means: U < 7V

The level of the logic signals must not exceed 35V.
CAL intern:
Change from low to high: The Machine starts an internal calibration independent
from the mode the machine is running in.
CAL extern:
Change from low to high: The Machine starts an external calibration independent
from the mode the machine is running in.
Change from high to low: approve that external test leak is closed and leak rate
signal is stable.
Signals at these inputs are only accepted if the location of control is set to „PLC“,
“All“ or „Local and PLC“.
