Settings
Characteristic
curve
If a value for
End value
that is greater than the
Start value
is entered, the output

Explanation
Measured variable
Main variable
Adjoining variable
Main variable
designates the
actual measured parameter
of the sensor (e.g. pH, oxy-
gen, etc.).
Adjoining variable
desig-
nates an additional mea-
sured parameter (e.g.
temperature).
Start value
within the measur-
ing range (sensor-
dependent)
Minimum spacing:
5 % of the measuring range
End value
Frequency (f) min.
0 to 120 1/min
Minimum spacing:
10 1/min
Frequency (f) max.
Frequency with error
0 to 120 1/min
In case of system errors or
sensor errors (see
page 156), the relay
switches with the frequency
specified.
