8.5 Workflow: Current Loop Setup
8.5.1 Indroduction
The device writes the measured concentration of the main substance as electrical
current to the 0-20 mA-current loop interface.
The concentration range of the output substance is mapped to a sub-interval within
0-20 mA.
Outside this sub-interval a mA-error value and a mA-idle value can be defined.
The error value is set when a measurement has failed to produce a valid
concentration.
The idle value is set when no valid concentration is available yet or when the interval
mode is not active.
8.5.2 Electrical Interface
The current loop must be connected to the
Signal Converter

socket at
the rear of the housing according to the following diagram:

INFORMATION!
For concentration value output through the 0-20mA current loop the
