West Control Solutions CI 45 - Manual (Page 24)

A non-heated
l probe is used, if the temperature is not constant. In this case, the temperature in addition to the
probe mV value must be measured. For this purpose, any temperature measurement with analog input INP2 can be
used. During function selection, input INP2 must be set for measurement (
CONF/InP.2/I.Fnc=1).
Configuration:
O
2
-measurement must be adjusted in function 1 :
Func r Fnc.1 7
O2-measurement with constant probe temperature
(heated probe)
8
O2-measurement with probe temperature measurement
(non-heated probe)
Connection
Connect the input for the lambda probe to INP1 . Use terminals I and 2.
If necessary, temperature measurement is connected to INP2.
Input 1 is used to adjust one of the high-impedance voltage inputs as sensor type :
Inp.1r S.tYP
41 special ( -2,5...115 mV)
42 special ( -25...1150 mV)
43 special ( -25...90 mV)
44 special ( -500...500 mV)
47 special ( -200...200 mV)
These high-impedance inputs are without break monitoring. If necessary, input signal monitoring is possible via the
limit values.
Further recommendations for adjustment:

Input 1 must be operated without linearization:
Inp.1r S.Lin 0 no linearization
g
With O 2 measurement, specification if parameters related to the measured value should be output in ppm
or % is required. This is done centrally during configuration.

Whether the temperature of the non-heated
l probe is entered in °C, °F or K can be selected during
configuration.
