Configuration of the external control (Option: IO module)

This feature requires an I/O module (optional) and the function must be activated
This feature can be used for the external control of the analyzer. With the help of the external control follow
operations can be done:
Externally controlled sampling point selection,
•
Stand-by.
•
The commands will be given by a 4-bit binary number, which will be built through four external signals. The pins
for the signal are shown in the sketch below. It exists two different types to set the four pins:
Potential free relay contacts.
•
4-20 mA signal inputs.
•
Through one 4...20mA input.
•
The settings-menu can be found at the path:
The user can set three different types for the external control. The types can be found at the sketch below.
Connection of the external control via relay contact
This feature can be used for externally controlled sampling point selection, zeroing and stand-by, using external
potential free relay contacts, see also diagram in $4.4
The relay contacts build a 4-bit binary number: RC4 - RC3 - RC2 - RC1 open=0, closed=1.
Let us tell this number 'status number'.
