MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC
Input Type Redundant: Consolidation
If you select Redundant as Input type, you must configure the Consolidation
parameter which specifies the measurement value to be used.
Select the measurement values to be used by MA2/MA4
comparators and sent as analog data to M1S controller:

Input Ain1, 2: Use the values supplied by the connected Channel.

Ain1R, 2R: Use the values supplied by the connected Channel.

Maximum: Use the maximum value supplied by channels 1 or 2,
whichever is greater.

Minimum: Use the minimum value supplied by channels 1 or 2, whichever is less.

Arithmetic average: Use the arithmetic mean of the values supplied by channels 1 and 2.
Measurement unit: Scale and type of input
You must specify the unit (e.g. Celsius degree, Bar, kg, m/s) and the scale of the
measurement. The MA2/MA4 module will calculate the relationship between these
values and the corresponding measured current or voltage values (scaling) based
on the condition that the sensor has a linear characteristic.

Scale, minimum value: It is the lowest value in units corresponding to the minimum
output value of the sensor (4 mA for a 4÷20 mA sensor, 0 mA for a 0÷20 mA sensor
and 0 V for a 0÷10 Vdc sensor).

Scale, maximum value: it is the highest value in units corresponding to the maximum
output value of the sensor (20 mA for a 0/4÷20 mA sensor and 10 Vdc for a
0÷10 Vdc sensor).

MSD assumes that the sensors have a linear transfer function and, as a consequence,
automatically computes the slope and the offset of the transfer function on the basis
of the values entered by the user.

Do not use a configuration of the function block as 0÷20 mA or 0÷10 V input for safety purposes.
If you use a configuration of the function block as 0÷20 mA or 0÷10 V input for non safety
purposes, implement all measures required to avoid unintended equipment operation and any
other hazard.
