Chapter 6 Functional principle
6.1.2 Overflow module
This module monitors the measurement range limits of the raw value. If a universal input was, for example,
switched to "4-20mA" mode, a raw value of 2mA will violate the measurement range. The overflow module is
only available for the 4 universal inputs in "4-20mA", "0-20mA", "0-2V" und "0-10V"channel modes.
The following table specifies the relevant parameters for the module:

6.1.3 Scale module (inputs)
This module rescales the raw value (e.g. mA) to the required measurement value (e.g. mm). The scale
module is only available for the 4 universal inputs.
The following table specifies the relevant parameters for the module:

6.1.4 Trim/sensor offset module
The installation height of the sensor can be taken into consideration with the help of this module. It also
enables the zero point to be adjusted without having to change the value for the installation height again. The
trim/sensor offset module is only available for analogue modes ("0...20mA", "4...20mA", "0-2V", "0-10V"). The
"Trimming" parameter value and the "Sensor offset" parameter value are added to the output value of the
scale module (see "Scale module (inputs)" on page 29). This means that a negative prefix must be set for the
"Trimming" parameter (see "Additional explanation on the zero point adjustment and installation height of the
sensor" on page 79) if the scaled measurement value should be reduced during the zero point adjustment.
