Connection of the external control via one 4-20 mA input signal
The user has the opportunity to control the analyzer with only the first 4-20mA
input (see sketch below). The different commands will be given by the changing
of the current signal. The offset-signal is 4 mA. Every 1 mA step describes a
condition of for the external control. Overall, the analyzer can take 16 different
statuses. The first status is by 5 mA (4 mA+1 mA) the second is by 6 mA (4 mA +
2 mA) and so on until the 20-mA signal is reached.
The connection of the one 4-20 mA signal is a two-wire connection.
