The temperature protection using the RTD sensors can be done using the function
block. The measured temperature can be fed from the RTD sensor to the function
input that detects too high temperatures in the motor bearings or windings, for
example. When the ENA_ADD input is enabled, the threshold value of the internal
comparator is the sum of the
Start value Add
and
Start value
settings. This allows a
temporal increase or decrease of the level detector depending on the sign and value
of the
Start value Add
setting, for example, when the emergency start is activated.
If, for example,
Start value
is 100,
Start value Add
is 20 and the ENA_ADD input is
active, the input signal needs to rise above 120 before MAPGAPC operates.
