4.3.2 Wiring of pH sensors
The converter CONTROL 200 can be connected to either a standard pH input or differential pH input. The
dual input pH is designed for use with pH electrode systems that incorporate a solution earth (ground)
connection to provide low glass impedance and out-of-sample/broken cable warnings.
The wiring of pH sensor PF12 with ABB combination electrodes to a converter C200 as sensor A and/or B is
described in the following tables:

For use with different sensors refer to corresponding instruction manual !
If sensor diagnostics are required, ensure that Diff. Input for the relevant sensors is
set to “YES” – see Instruction Manual Control 200, Part 2 - Software !
If sensor is equipped with a 2-wire temperature compensator, link terminals B9 and
B10 (and B1 and B2 if dual input analyzer) !
